Waiting for some parts for the transmission, so here's a photo of the new fuel line installed. I went off of what I saw in the TMs, so I'm not sure how accurate it is. There was a filter with a glass bowl previously installed.

Thanks - Exactly what I needed to see.  I ditched the French fuel line/system and wasn't sure on how to do this.  I picked up a rebuilt carb and had all the pieces except for the 90 degree elbow.  Between your pictures and the photo in the TM, I have a pretty good idea on how to run the line now.

I made some more progress on the transmission today with the arrival of some new parts.

A couple more problems with the old parts. The countershaft bearing surface is pitted. The bearing washer that bubba put in is wrong.


Here's the pretty much new countershaft gear set.

In between working on the transmission/transfer case I am working on a couple of other parts also.
 I got tired of looking for someone to repair the cylinder in the original hydrovac. The best answer I got on it was "if you just use it in parades moving slow it should be ok". That wasn't an answer I wanted to hear so I roughed in a modern one.

Nice.where did you pick up the booster and how much. I have a new Hydrovac in the box that sat for 40 plus years so I'm assuming all the seals are bad so until I get it rebuilt I need a sudsitute.

I bought mine at a local carquest. I used the numbers from a post here. I can dig up the one i bought, there are 2 different ones. This one is the larger of the two. I would have bought the other one, only for ease of mounting due to the smaller size. I have also seen this one used on a couple of halftracks succesfully. The cost was $160. Its tight and hangs below the step about an inch.

The transmission is finally done.

These were the big hold up, most are close. The original is in the lower left corner, it was bouncing around on the shaft. A friend finally matched one up at a Peterbuilt dealer. The snap ring would fit the shaft, but I wanted to stay with the constant section snap ring.  It holds 3rd gear in place.


Now onto the transfer case, here's the internals.

The transfer case is almost done. I have to get some shims in order to set up the end play on the shafts to  finish it up. Here's a couple of pics.
The intermediate shaft gear and needle bearings.

The gears placed in the case.

Setting the shaft end play on the intermediate shaft. I ran into a potential problem doing this, I will make a post in the transmission/transfer case section.
