Title: M2A1 Front End and Engine Rebuild
Post by: steve1973 on February 04, 2015, 02:34:33 AM
Well, this will be another chapter in my halftrack restoration. I left off two years ago with rebuilding the entire rear of the halftrack from the B pillars back down to the frame. I rebuilt the rear drive axle, installed a original rear floor, had made new track armor and installed new tracks. All this just in time for the MVPA convention in 2013. This last summer, 2014, I put some 200 miles on my track ending at Don's house for his yearly Camp Gleason. Just prior to all this I blew a head gasket. While changing that the cylinders were inspected and were in rough shape with pitting where the engine sat for many years. My mechanic adjusted the timing and it started easier but ran rough driving. Afer the event he came out to Don's to look at both of our tracks as his was running rough also. we put new plugs in mine and he re-adjusted the timing. It was then he gave me the bad news. I have a low end rod knock. That was it so me. Don trailered my track back to the shop awaiting a new engine.

So, the game plan is to remove the front armor, drop the transmission and transfer case, pull the engine for rebuild, repair radiator and radiator armor and put everything back together. If time allows I will also pull the cab/cowling as an assembly for rebuild, sand blast and paint everything and have it ready for the 2016 convention in California if not Tower Park first.

So on Monday, with the help of Don, the hood, fenders and front armor came off. I think I busted every knuckle I have. All I can say is I love my air tools and air chisle to split nuts.  ;D  Here are som photos of my progress so far.

Upon further inspection I found several items needing replacing. They are:

Driver's side radiator support. Not sure if there is a difference between left and right. Mine is broke.

Control rod to open and close the shutters along with turnbucle in cab.

(http://www.surfacezero.com/g503/data/500/medium/DSCN2257.JPG)

Upper radiator armor brace. I will have to verify wich side and will get a photo. This looks to be a cast piece and has a raised mount for the X-brace.

That's all for this report.

I finished disassembling the front nose section. The broken brace I need is for the driver's side. See photo below. I also rummaged through one of my parts bin and found a control louver rod so that is one item off my list.

(http://www.surfacezero.com/g503/data/500/medium/DSCN2260.JPG)

So, I need one of the braces above and a radiator side rod support. any help is greatly appreciated.

There are two or three types of front end armor as fare as the way it is put together. I will try and get some photos next week of mine and it is in pieces now.

Made a little more progress since I last posted. I removed all three drive lines, removed the PTO, removed most of the front floor boards and the lower cross brace under the transmission. I hope to remove the radiator and transmission tomorrow, I still need to remove the exhaust first. Here are some new photos.

The one smart thing I did this time was to remove the steering wheel for more room. Sure is nice having the right tool for the job. I got the puller from Saturn Surplus.

I'm making slow progress on my track. I got the winch off today and removed the rest of the floor plates and supports. I'm having trouble seperating the tailpipe form the muffler. That is the only thing holding me up from removing the transmission. I'm hoping to have the transmission out by Friday. Photos below.

I made some big progress on Monday with the help of Don. We removed the front armor/cowling, transmission and engine. The halftrack looks kind of funny with only the rear armor on it. Once I get back from Tower Park I will finish stripping the frame getting it ready to clean and paint. I will most likely remove the front axle as I have a broken leaf spring to replace and it will be easier to clean.

It's been two long months since I last worked on my track. Monday I put 12 hours in at my shop and with help from Don and my mechanic Matt I got a lot done. Thanks guys. First, finish stripping the front half of the frame. The front axle was removed along with the springs and spring hangers. There where some other brackes and brake fittings that were also removed. I also put a temporary pintle on the front bumper. I made a bar wit D rings on both ends so that I can move my track in and out of my shop with my truck. I made two videos on Youtube in the past loading two halftracks on a flatbed truck using same method.

Here are the videos

The second haf of the day was spent tearing down not one but two motors. The first was my spare motor that I purchased from my mechanic some years ago and the second came from my track. This took the rest of the evening and wrapped things up at 8 PM just in time for me to go to work. What a day. We got a lot done. Now for some cleaning.

Now that summer is over I can get back to work on my halftrack. progress has been slow. I still need to clean the frame but the front axle and all the front suspension components have been cleaned. Some parts have been painted and re installed. I delivered my engine to my mechanic, Matt, so he can start on the rebuild.

(http://www.surfacezero.com/g503/data/500/medium/20150922_115810.jpg)

The block will be bored out .040 over while the crank will be .010 under on the rod and main bearings. The cam will remain standard. All the parts have been ordered to rebuild both engines. I sent out the shocks, carburetor and fuel pump for rebuild and just got those back today. They look great.

I got some more grunt work done over the past two weeks. I finally was able to get my track pulled out of the shop for pressure washing. I spent a good three hours getting as much grease and dirt off the frame. I got the track back in just before the rain started.

This weekend I spent a few days with Bud going over some halftrack stuff and to deliver my exhaust manifold to get repaired. one of the ends was cracked bad. I found a place in Portland, Oregon that does this kind of repair. They recommended that due to the age of the exhaust manifold that I should have it ceramic coated. This will prevent future cracks and strengthen the manifold. the other big plus is that it will retain 50-60% of the heat. This may help in the vapor lock problems.

I made it back from my trip last night so today I spent cleaning the frame with wire wheels, 3M sanding discs and my grinder with sanding discs on it. What a mess it makes! ;D Here are the results so far.

Not much new to report. I've been busy with other things lately. Here is what's new with my project. Frame is painted. I still need to get some other small parts painted before the engine can go back in. The engine is looking great. I had a small hang up when I found out I hade the wrong bearings for the rods and crank. I had to order new bearings and a harmonic balancer. I did find out the NOS radiator is French. Here is the brass name tag on the radiator.

Here are some engine photos.

(http://www.surfacezero.com/g503/data/500/medium/20151130_135509.jpg)

The exhaust manifold had a crack that was professionally repaired the ceramic coated. this will reduce heat loss and help prevent any future cracks.

I made a lot of progress in the last three weeks. I turned the front half of my shop into a paint booth and am turning out 1 to 2 batches of painted parts a week. I have also taken three truck loads of parts to get sand blasted and now awaiting paint.

(http://www.surfacezero.com/g503/data/500/medium/20160621_201112.jpg)

I have re installed most of the components back on the frame and touched up painting the bolts. One upgrade I did was install a later brake/clutch peddle assembly that omits all the old brake monkey motion. I had new brake lines made and installed. Lastly, I started to install my new wiring harness from Vintage Wiring of Maine.  This is a must have for any restoration but is a whopping $1400 for the harness. Well worth the price though.

Everything was going great. I got word my engine will be ready soon as my mechanic was finishing up installing all the external stuff. The next day I got some bad news. While installing the intake/exhaust manifold assembly on end broke off while snugging up the bolts. OUCH!!!

(http://www.surfacezero.com/g503/data/500/medium/DSCN3317.JPG)

Good news, I have a new end on the way thanks to Gary. The other good news is my engine was delivered on Friday and looks great.

I have a few more things to do on the front frame like securing the wiring and install a few more pieces then the engine will be ready to go in. I’m awaiting for another shipment of parts from Kevin and then it will be ready to install. Next Tuesday I get my transmission/transfer case back. I need to mock that up to the engine then do some massaging on the bell housing where the U-joint for the PTO hits to create clearance. Once this is done the assembly can be re installed.

Looking great Steve.

Just an FYI...You probably know this but I will mention it anyway. Make sure they re-machine the mounting surfaces on the intake and exhaust manifolds so everything is on the same plane. When I replaced my exhaust manifold the first time (about 5 years ago) I did not do this as they looked "ok". Well it wasn't a perfect match and led to the exhaust manifold cracking. This last time when I had it off and repaired I made sure to have them both machined as a matched pair.

a quick tip I had to learn the hard way, but was able to fix b/c I saw it happening.  When removing the steering wheel, do not fully remove the steering wheel nut.  If you do and you use the tool that is shown in the picture with the correct piece that fits inside the column, the threaded area will be crushed and you'll need to either file out the threads, or re-tap them you catch it in time.  I destroyed one steering column that way many years ago.  When you leave the nut on, it spreads the force out over a much larger area, when the steering wheel starts to come off, just back the nut off a little more, catch up with it, back it off more until everything comes off.




Made a little more progress since I last posted. I removed all three drive lines, removed the PTO, removed most of the front floor boards and the lower cross brace under the transmission. I hope to remove the radiator and transmission tomorrow, I still need to remove the exhaust first. Here are some new photos.

Lots of work has been done since my last post. First thing is I needed to fix a clearance problem with my PTO driveline. I had someone come out from a driveline shop and it was determined that shaving a little off of the U-joint corners would do the trick.

(http://www.surfacezero.com/g503/data/500/medium/DSCN37741.JPG)

(http://www.surfacezero.com/g503/data/500/medium/DSCN37771.JPG)

Next item on the list to complete was the wiring and replace the fuel line from the fuel block to the filter. I ended up taking a shower in gas on that one. Yes, I did drain the gas tank with the help of Don. If I remember correctly it was below the fuel pick up line. A good two gallons came out. What a mess. After that was cleaned up I installed the new line and then moved on to the wiring. I got as much as I could done with in the frame until the cowling gets reinstalled. One thing I can't stress enough is to take lots of photos when dismantling your halftrack. I took many photos of the wiring, brake and fuel line routs in the frame. This made an easier job when reinstalling new stuff.

(http://www.surfacezero.com/g503/data/500/medium/DSCN3786.JPG)

Next item was to paint the transmission and PTO before installation.

(http://www.surfacezero.com/g503/data/500/medium/DSCN3780.JPG)

Sunday was a big day. Engine install day!! ;D I had the engine in by 10 am and the rest of the day spent getting ready for the transmission install on Monday.

Installing the clutch was the first order of the day. No problem their or so I thought. Once installed I went to remove the pilot tool, spare input shaft, and I hear a thud. I tried to reinstall the tool and would not go in. the clutch plate dropped due to no pressure on it. I ended up adjusting the clutch by turning the adjustment clockwise until I had pressure on the disc to hold it in place. Once that was done it was time to install the transmission. Well, the tranny was stubborn and did not go in easy. I ended up using a hydraulic jack between both driveline mounting flanges to push it in gently. I did go in and everything seems to be ok. Big thanks to my Dad and another friend for their help in this. Here is the end product of the day.

The next step is to adjust the clutch properly and install the radiator.

Looking good.

The new mfg drive line flanges are slightly larger than the originals. So I had to shave mine down as well.

Thanks for the nice replies.

Made some more progress. Working on cleaning parts ready for paint. These are some of the small detail pieces. Sandblasting is time consuming isn't it. but when done it makes a great start for new paint. I also have a large parts wash tank and vibratory tumbler which does a fantastic job of cleaning bolts. Here are some of my results.

At the same time I'm starting to disassemble the dash and cowling. I just need my helper to finish it up.

(http://www.surfacezero.com/g503/data/500/medium/20160906_214602.jpg)

I'm hoping that I can finish this up by the end of the week if my helper has time. ;)

Well, I got busy with work again since my last post and a cold but got a lot done in the past few weeks. I was able to finish stripping the firewall/cowling to get ready for disassembly. Another good friend Steve J. helped me with that.

(http://www.surfacezero.com/g503/data/500/medium/DSCN3871.JPG)

I also got another batch of parts painted.

(http://www.surfacezero.com/g503/data/500/medium/DSCN3873.JPG)

Here are a few detail photos of the rigid vacuum line and oil gauge lines. I recall someone asking for these in the past.

(http://www.surfacezero.com/g503/data/500/medium/DSCN3870.JPG)

My breather for the hydrovac on my halftrack is tucked up underneath the dash. When I removed it I tilted it over and a bunch of oil came out. Does anyone know if this is a oil bath air cleaner and does it come apart?

(http://www.surfacezero.com/g503/data/500/medium/DSCN3875.JPG)

 We got everything removed and now ready for Don and I to disassemble. We did this last Monday and took everything to the sand blasters on Tuesday.

(http://www.surfacezero.com/g503/data/500/medium/DSCN3880.JPG)

 By then I got another cold and have been sick ever since. I'm over my fever now and starting to feel a little better now and hope to get back at it on Monday.

Steve,
That is an oil bath filter. I have the same one. If I remember it does screw apart. Once you clean up the canister you will see the fill line.

Made some more progress this week. It's all about sand blasting and painting for a while. I should be able to re assemble the firewall and cowling by Friday. I will be painting the windshield frame and top cowl piece today. Don has my dash and is going to remove the bolts we drilled out. That is after he gets over the cold I gave him, sorry Don. :-[

Cowl/firewall section going back together.

(http://www.surfacezero.com/g503/data/500/medium/DSCN3884.JPG)

Another batch of parts being painted. Doing a lot of cleaning, sand blasting and painting now.

(http://www.surfacezero.com/g503/data/500/medium/DSCN3883.JPG)

Getting my e-break ready to install. I also need to install the PTO. That will get done in the next few days I hope.

(http://www.surfacezero.com/g503/data/500/medium/DSCN3885.JPG)

Doing some repair work on the dash before painting I hope to reassemble the dash next Monday. I also need to replace two windshield retaining studs. I will be doing that tomorrow.

Post by: steve1973 on March 02, 2017, 09:50:24 AM
One thing to note. As I've been sandblasting parts I've been looking at the stamp on all the original parts. I know by the frame number it is a White unfortunately I don't have the original data plate. that is the biggest bummer. What I have noticed are the marking for the armor plate manufacture. Majority of the symbols are square, according to Kevin, are White. I have also found a lot of Diamonds which I think id Diamond-T and keystones which must be Autocar. All this armor is from cab forward and when disassembled looked to be all original fasteners, never touched in many years. My thought it must have gone through a rebuild and when they disassemble the vehicle all the parts go in like piles for inspection, cleaned and put back out for reassemble with the first piece going to witch ever vehicle needs the part. Not manufacturer specific. I have also notice some small cracks in the armor in at least 3-4 pieces so far. Paint hid them well.

Today's list of things to do:
1.    repair and paint the dash - Most important thing today
2.    repair windshield frame
3.    pain another batch of parts
4.    bead blast small parts
5.    put PTO back on transmission

I hope to get most of this done today.

Been busy the past week. The dash and windshield frame are both repaired and painted.

(http://www.surfacezero.com/g503/data/500/medium/DSCN3887.JPG)

(http://www.surfacezero.com/g503/data/500/medium/DSCN3888.JPG)

(http://www.surfacezero.com/g503/data/500/medium/DSCN3897.JPG)

I did get the PTO mounted back on the transmission and decided to fill with gear oil. I tried using a pail pump from Harbor Freight. That was a bust as the tubing ruptured and oil went everywhere. There are some things not to get at harbor Freight and this is one of them. 

(http://www.surfacezero.com/g503/data/500/medium/DSCN38901.JPG)

I ended up taking that back and getting a better hand pump at a farm store. I will be using this today.

(http://www.surfacezero.com/g503/data/500/medium/DSCN3911.JPG)

Got more parts painted and now running out of space to store the finished parts.

(http://www.surfacezero.com/g503/data/500/medium/DSCN3898.JPG)

(http://www.surfacezero.com/g503/data/500/medium/DSCN3899.JPG)

Now the fun part. I get to put stuff back together. I reassembled the floor vents and the radiator armor. One louver is missing as I needed to do some body work on it. It was very pitted so some body filler was used and will be painted today.

(http://www.surfacezero.com/g503/data/500/medium/DSCN3907.JPG)

(http://www.surfacezero.com/g503/data/500/medium/DSCN3909.JPG)

Starting to get parts laid out to do back on the dash and firewall.

(http://www.surfacezero.com/g503/data/500/medium/DSCN3906.JPG)

(http://www.surfacezero.com/g503/data/500/medium/DSCN3905.JPG)

As far as the ignition system goes I'm making a few changes for the better I think. All this stems from my experience with old Chevy trucks. I still have my 1951 Chevy that I need to finish some day. here is my list of changes.

1.   Add a pertronix unit to replace the points and condenser. This was done several years ago and works great.

(http://www.surfacezero.com/g503/data/500/medium/DSCN38161.JPG)

2    Add a multi spark ignition module. This will be hidden in the original coil box. this will give multiple sparks per cycle instead of just one. it should help starting, idling and prevent plugs from fouling.

(http://www.surfacezero.com/g503/data/500/medium/DSCN3900.JPG)

3.   Add a vacuum advance unit to the distributor. This is a factory bolt on item that Chevy used on its six cylinder engines using a similar distributor. I only need to machine an 1/8" from the base.
4.    Change the air cleaner to the paper element.
5.   This next item came with my halftrack. A Marvel Mystery Oil Inverse Oiler. This devise put the correct amount of Marvel Mystery Oil into the intake manifold and lubes the valves and keeps things running good.

The one change I had made a while back, adding an electric fuel pump, I'm changing back to original. This is so I can use my windshield wipers. I may add a vacuum reservoir.

That's about all I have to report for now. More to come.

Well, it's been a while since my last post. I've been having difficulty with my health lately. Anyway, I finally was able to get some work done on my halftrack. I have since finished my dash and installed it back in the cowling.

I'm still plugging away on the firewall and dash. It's amazing how fast it is to take one of these machines apart and how slow it is putting it back together getting all the gingerbread details just right. Anyway, I had another slow down in my work. Kidney stones, I don't recommend them. They are not fun. I'm feeling a bit better now. Got some parts re plated and look great.

(http://www.surfacezero.com/g503/data/500/medium/20170817_102411.jpg)

I didn't want to paint them. They look better plated. I hope to be ready to install this onto the halftrack by sometime next month. Enjoy.

Made lots of progress this last week. First, thanks for all the kind comments! ;D The one thing I like where my shop is that I'm close by many great parts places. I have a rubber and line place, fastener place several parts houses and a auto paint supplier. Anyway, back to my progress. All the fuel and vacuum lines are in. Thanks to Eric at Pacific Rubber for that. Here is the fuel line set I had made up. It runs from the frame mounted fuel filter to the fuel pump. $50.00 plus shipping if anyone is interested.

(http://www.surfacezero.com/g503/data/500/medium/20170921_151216.jpg)

I filled up the engine with break in oil, did some more painting and sandblasting. Finished up all the electrical on the firewall and my add on spark module in the coil box. Installed the generator with the help of my crane.

Hi Gary,

When I got my halftrack it came with two unique items. One, was a Stewart Warner electric fuel pump for a Ford GT-40 race car and this canister. After doing some research I found out it was an accessory item, non military, from the 30's and 40's made by Marvel Mystery Oil and is called an inverse oiler. Using vacuum it draws in metered drops of this fluid into the intake which allows lube to the engines top end. I thought it was worth to keep this item. I went on eBay and purchased an NOS one and will sell the one I removed. The fuel pump is also for sale.

Post by: steve1973 on September 30, 2017, 08:01:35 AM
Made some headway this week in preparation for the first engine start now planned for this Sunday. Monday I purchased a new 8D battery and installed it using the original battery hold down brackets. The battery is a little narrower than the original Willard battery so I had to use some extra nuts as spacers to cinch up the end brackets. I will need to make some new rods in the future to correct this.

(http://www.surfacezero.com/g503/data/500/medium/20170925_144600.jpg)

 The rest of last week I was busy with work so I didn't get much done till yesterday. Friday I started going through my mental check list making sure things are ready for Sunday. I did some more painting for the exhaust brackets and such, tightened up the lower generator bolts and then decided it was time to fill the engine up with coolant. For reference, the cooling system holds 24 quarts or 6 gallons. Everything was going good till I put the last gallon in, LEAKS!!! ??? :o It was now time to chase and fix leaks.

Water pump drain loose and was tightened, leak stopped.
Temperature sensor loose and was tightened, leak stopped.
Various hose fittings leaked. I got a set of the old style hose clamps and they leaked at the same spot where the clamp was drawn together. Out with the old style and back to the newer style. Problem fixed except for one. I can't seem to get the hose below the oil cooler from weeping coolant. I may have to replace that hose, we'll see.

(http://www.surfacezero.com/g503/data/500/medium/20170929_174542.jpg)

That's all. More to come. I will be installing the exhaust today and testing the electrical especially for proper groundings.

OK guys, the first engine start was a success!! Only a couple of problems. I had the distributor wired for counter clockwise and I was off one plug location. Not bad I think. Once fuel got to the cark it fired right up and sounded great. Oil pressure stayed between 40-60 psi and temp was 160. I still had some coolant leaks to fix. I noticed a big difference on how strong the engine sounds from before. I think the Pertronix ignition and MSD spark control helped a lot with that.

Note: if you are at the same point as me. Fill with water first. once you have leaks fixed then add coolant. lesson learned. ;)

I want to thank my mechanic Matt for the terrific work he has done and to Don, Steve J., Steve Sr. for there help when needed. Also a big thanks to Eric for coming out to my shop and making all my brake, fuel and vacuum lines. Enjoy the video.

Hope everyone had a great Thanksgiving.

This is a little off topic but thought I would share it anyway. I just returned from Hawaii with my Dad. I was able to visit the USS Arizona memorial, USS Missouri, air museum on Ford Island and touring the USS Bowfin WWII submarine. The highlight of my trip was staying overnight on the USS Missouri in an actual bunk, it was a little on the tight side. Also, my Dad had arrange for us through public affairs at the sub base on Pearl Harbor for a grand tour of Pearl Harbor and Ford Island. On the tour we saw the old hospital that was shot up, the location where the USS Nevada beached herself trying not to block the harbor, USS Oklahoma Memorial, USS Utah Memorial and the WWII submarine memorial on the sub base. Other highlights included the sub barracks where my Dad stayed, Beeman's Liberty Center and the dive tower where they practice surfacing from the deep. Last but not least we spent 3 hours on board the USS Olympia SSN 717, Los Angeles class fast attack nuclear submarine. How can you top that! ;D Due to time and lots of traffic I was not able to visit any of the Army museums. :( I guess that is for next time. ;)

OK, back to my halftrack project. I spent the day taking apart the passenger side half of the front axle for cleaning and inspection. I got most of it apart today. tomorrow I will be cleaning and hopefully reassembling it then moving onto the Driver's side. Here are some photos.

In a prior posting some years ago I had already did the front breaks, bearings and drums so it all came apart nicely. I do need to put new wheel cylinders in again as the ones I rebuilt leaked. Thanks to Kevin Lockwood I have all new wheel cylinders to install.

Here is the link to the previous work on the front axle and brakes.

http://g503.com/forums/viewtopic.php?f=24&t=212293

The driver's side was much worse as there was quite a bit of rust and debris on the axle and in the axle tube. I had to come up with a way to scrape out the inside of the axle tube.

(http://www.surfacezero.com/g503/data/500/medium/DSCN4546.JPG)

I went to the local hardware store and got a 1/2" X 3' threaded rod with a 2" fender washer at the end.

(http://www.surfacezero.com/g503/data/500/medium/DSCN4548.JPG)

With the axle tube scrapped out I used my small shopvac to vaccum out all the loose debris. I then cleaned the Driver's side axle shaft of old grease and rust then prepared both axles to re insert back in the axle housing. I installed two new wheel cylinders the proceeded to put the axle back together drums and all.

(http://www.surfacezero.com/g503/data/500/medium/DSCN4549.JPG)

Now that the axle was done I moved onto installing the floor supports. With that it was time to wire in my master cut off switches for the ignition and radio.

The next project I worked on was to fix the fuel valve to the gas tanks. Earlier on in this rebuild I added an original fuel filter to the frame. Doing this I had to make a new flex fuel line from the gas tank fuel valve to the fuel filter. To change out this line I removed the lines to the tanks. Well, when I went to reinstall the tank lines I got the driver's side one in at an angle and damaged some threads. Luckily with the help of my line guy, Eric, using a 1/2"-20 bottoming tap he was able to fix the threads.

One thing I have to mention is that the jerry can holders come in very handy as tool tray. Plus you have one on each side. ;D

First, I want to tank everyone for your kind comments. ;D

At this point I decided to fix my leaking steering box. I rebuilt this a while back but didn't seal the cover very well and it has been leaking gear oil ever since. Here is a link to the steering box rebuild http://halftrackinfo.com/index.php?topic=941.0. Since my halftrack is an M2 variant it uses a Ross "T" steering box which is also shared with the M3A1 Scoutcar. I sent off the cover to my gasket maker and they made a template for their file and sent me back 10 gaskets. I'm keeping 2 and the rest are for sale, $15 each and $7 for shipping if interested.

Back to the front axle. It's dust boot time! When Don and I did Zelda's boots I can recall some not so fun times. Due to the age of the NOS boots they have shrunken in size. They were a bear to put on and after many attempts and several days later we got them on. Well, I'm going to try newer made M35 boots and wire bands. This is my project for the week. Fun times ahead. ;)

Hello everyone. It's a new year and time to get things rolling again. I left off working on getting those boots installed. Well, I fought for a day trying to get one on myself and ended up only getting the inner ring mounted on one side. I needed an extra set of hands. I had a co-worker that was nice enough to come help me for the day. The passenger side went on fast. It was done within an hour. I did find out that the outer clamping ring is a bit brittle as it broke when locking the two nuts together. ??? Good thing I have spares! ;D The Driver's side inner was a chore. We were having trouble getting the two ends close enough to put the screw and nut on. My co-worker, Ryan, had the bright idea of looping a piece of wire around the ends and then twist to draw the ends closer. this worked great and got the screw and nut on then cutting the wire loose. Boots done!! :P

(http://www.surfacezero.com/g503/data/500/medium/DSCN4589.JPG)

The M35 boots were much easier than the original NOS ones Don and I put on Zelda. I would recommend loosening the bottom plate of the steering knuckle when doing this.

Since I had some extra help we moved on to putting the two toe boards in. This is another two person job. Once those were in we installed the draft seals for the clutch and brake pedals. The draft seal kit can be purchased from Kevin Lockwood.

(http://www.surfacezero.com/g503/data/500/medium/DSCN4590.JPG)

I was going to install the steering column but needed to clean up the draft seal clamp for the column shaft first. I was also going to install the dimmer (tilt) switch but didn't have any number 12 screws. That will be the next project.

Making more progress over the last weekend. I got the steering column back in but had a problem. When the column is mounted in place there is a clamp that goes over the pitman shaft housing from the steering box. My halftrack has two brass shims that go around this housing before being clamped in place.

(http://www.surfacezero.com/g503/data/500/medium/20180130_141903.jpg)

Well, I put everything back as original and was unable to turn the steering shaft freely. I loosened up the column and things moved fine. I decided to take out one shim and everything seems to work fine.

(http://www.surfacezero.com/g503/data/500/medium/20180130_141919.jpg)

The drag link was installed next then all grease points up front were lubed. With excess grease wiped off I painted all the zerk fittings red and once dried installed the covers on the drag link ends. These are from Kevin Lockwood.

(http://www.surfacezero.com/g503/data/500/medium/20180129_151643.jpg)

One of the next items to reinstall is the drive line. Before I did that though I decided to put new U-joints in.

(http://www.surfacezero.com/g503/data/500/medium/20180130_141647.jpg)

The front axle was finished up by installing the flexible brake lines. At this point it is time to sand blast and paint more parts.

(http://www.surfacezero.com/g503/data/500/medium/20180203_212601.jpg)

I was able to get some small parts done in my small blasting cabinet but I heard from Don that the place we take our big stuff to get sand blasted burnt down to the ground last week. :'( I will have to see if they will still be in business or temporarily find another place.

More armor being painted.

(http://www.surfacezero.com/g503/data/500/medium/20180203_212539.jpg)

Time for another update. Lots have happened since my last post. The big news is that I found a house and moving to the country, Yeah!! ;D With my closing date looming I need to kick it up a notch and get to work on getting the halftrack rolling again. I've been off work since last Friday through next Monday doing nothing but working on the halftrack. I've been at the shop everyday working at least 10 hours each day to get the halftrack rolling again. At this point it is not about getting it done but to get it at a point where it will move safely under its own power for the up coming move. Here is some of what I've done.

The all three drive lines are in place and the main fuel line is hooked up again.

(http://www.surfacezero.com/g503/data/500/medium/DSCN46561.JPG)

Painting parts is going on every day with the doors all done and finishing up the hood today. I still have to clean all the hinges and door components though.

My parts remaining and staging area. I'm running out of parts to put on. :o I guess that's a good thing. ;D

(http://www.surfacezero.com/g503/data/500/medium/DSCN46541.JPG)

Finally, the halftrack as she sits today. The winch is installed, top center hood piece in place. Almost ready to roll....

Made a lot of progress since my last post. I got my other gas tank back from Don since he has his own tanks now. Both tanks are wired in and the fuel gauge works! That's a big plus. One modification I did was to notch the gas tank covers so I don't have to remove the fuel line each time. I've seen this on several halftracks as a field modification.

(http://www.surfacezero.com/g503/data/500/medium/DSCN46621.JPG)

I finished pluming the fuel line to the engine so it can run from the tanks but had problems starting the engine. It just didn't want to start but would run if dribbled fuel down the carb. After some trouble shooting It was found that the float wasn't allowing fuel in the bowl. Once adjusted the engine fired right up.

Don came over this morning to help with a few things like bleeding the hydrovac and brakes. I ended up having to disconnect my rear brakes due to rear hub seal leaks on both sides. So I'm using the front brakes for now. Once that was done we put the floor plates in and the front tires on. Lastly the steering wheel was installed.

You know what that means....

TIME FOR A TEST DRIVE!!!!!!!!!

This is the first time running under it's own power in two years. I don't know who was more excited me or Don. ;D

https://youtu.be/5tF8EpxxHow

Once the ride was over we went out and celebrated with lunch then came back and worked on doors. The lowers are on but will need to do some massaging on the driver's side door. That's all for now.

OK guys, here is a long overdue update on my halftrack. Sorry, no photos with this update.

Between getting inspections done on my new house, signing papers and getting ready to move, the halftrack took to the side lines for a while. I have since installed the fenders, front bumper, doors, windshield armor, hood and headlights.

On the passenger side door I added the pocket for the lube chart. Some years ago I purchased one from Outsider, painted it and then put it in that safe place. Well, when I needed it I couldn't find it so I bought another one from Outsider and installed it. Yesterday I was showing Don something and I found it! :D

For the most part the halftrack is done. I still have a few items to address but for now it can be moved or so I thought.

Since the first test run I have been having problems with fuel starvation. I've tried changing carburetors, bypassing both fuel filters and fuel pump with no luck. From the fuel tank selection valve forwards all have been bypassed. this means the problem is somewhere from the valve back. Just when I was ready to give up Don, once again, suggested that I blow the line with air. I finally agreed and so far that did the trick. Big thanks to Don!! :D

This Saturday Don and I are invited to a car show so I have a few more thing to do to get ready for Saturday. I'm going to make another test run today and finish up a few more items then its of to the car show. I will try and get some more photos posted soon.

Time to jump back three years and finish this post. For all you newbies here are links to my prior restoration posts.

http://halftrackinfo.com/index.php?topic=913.0

At this point I am scrambling to get the halftrack done for the move to the new house. I needed to get moved out of both of my warehouses ASAP as they were getting too expensive especially with my new house. So, they had to go. I do miss them to this day. Anyway, While getting the halftrack together I was getting a pole barn built to be my new shop at my new house. Here are some more photos as I get the fenders, winch bumper and lights mounted.
