I need some pics of the original chain that goes on the end of the winch cable. Got my new pto shaft installed and 240' of cable wound on the drum so trying to come up with what the chain is supposed to look like. (length, attachments, etc). Yea, I know I'm a little short on the cable, but when you get the cable for free you don't complain about it not being long enough. ;)
Thanks,
Steve

Thanks Steve. But at 20 links (about 2') that seems a little short compared to the chains you see on a lot of HT's? All the ordnance pics in Hunnicutt"s book the hook is on one of the tow hooks and the chain runs across over the other hook and part way back to the winch before the cable starts. I just can't see it good enough to count the links. Also the hook is permanently attached to the chain with a link, not with a clevis.

Hey Outsider, What size cable / wire rope did spool on your winch?

KC, 1/2" cable that came off an overhead crane.
Also I think I am going to use a "hammerlock" to attach the hook to the chain. If I were to cut a link and reweld it, it would weaken the link and knowing me I will probably end up using the winch some day. So stronger is better (and safer).

im glad i didnt buy any of those when i first saw them.
im planning on using the ones i pulled off cckw trucks. do they look like the halftrack style?
here is a pic one

The one you have there is 34 links, plus one oversize link on each end. From what I could tell from the pics in Hunnicutt's book (using a magnifying glass), that looks pretty close, including the cable clamp.

Well, Here is what I did.
Steve-O's picture of the cckw chain had 34 links, plus one oversize link on each end. Since I used the hammerlock on the one end I only had to make up for the one on the cable end. What I did was add 2 extra standard links to the total to make up for the length difference. The hook was an old one I had laying around that seems to match the original ones.

Here are a couple of pictures with the chain in the "storage" position as shown in the ord. pictures in Hunnicutt's book.

And a view from underneath.

Now for a little touch up paint, and the canvas cover and it will be good to go.

I was going to use the hook and chain from a CCKW but when I compared it to the original hook it was quite a bit smaller,so I assumed the chain was smaller as well. Could someone measure the links on a original chain for me, I need the length and width of the link,I have friend with a heavy equipment yard from an old mine,I'm sure they will have something I can use.
-
I don't have the dimensions of an original chain, but I used standard 1/2" lifting chain on my ht. It will match the strength of the 1/2" cable if I ever decide to use the winch for real. 1/2" tow chain will be the same dims as lift chain, just not as strong.

I actually use my half-track quite often to pull trucks out of the sand, I've helped place two mobile homes and have pulled three semi trucks out of the sand after they dug them selves down to the axels, so I will most likely use the winch at some point!

If you are going to use the winch you will need G70 or higher rated chain, and I would use a G70 or higher rated hook as well. Also you will want to find a snatch block or two so you can double or triple up the cable for a heavier pull.

I don't know why it is so hard to get the factory dimensions for this chain but no one would give it to me so I improvised, I have some friends with a large bone yard so I took the CCKW chain up with me and picked a couple of sections of 1/2 chain to match up with factory pictures, with new chain the links are too short, they looked stubby, but I found a piece with links that are 2 7/8 long and 1 3/4 wide, that looks much more correct,I used the elongated end rings off a CCKW chain,I cut and welded them,I made the chain 5 feet long, some of the period pictures they have the chain wrapped from hook to hook with the end of the cable just under the spool,I measured that it I got five feet, I wouldn't want to use it for lifting a load but for horizontal pulling I'm not too worried.

I've been sick for the last several weeks and didn't have a chance to reply. So here is a photo of an original hook. It is roughly 10 to 10-1/2 inches tall.
(http://www.surfacezero.com/g503/data/500/medium/DSCN0235.JPG)
As for the chain there is 33 links of 1/2" diameter links 2" wide and 2-1/2" tall. At each end is a pear link 1/2" diameter, 3" at widest, 4-1/2" tall. The cable or "rope" per manual is 5/8" 220 feet long. I know a lot of people use 1/2" instead of the 5/8" though. Below is a photo of an actual surplus winch chain and hook assembly.

Hope this helps.

Caution!!!!! You will snap those welded links in a heartbeat! even on an just a level pull.

I may have found a stock of these. 33 links plus 2 pear links which seems to be the consensus of the forum members. But the hooks on this thread are all over the place. In one photo it shows a hook over 10" tall. The next photo of an assembly shows a smaller and slightly different hook. I will have some photos of the assemblies I found asap but would like to be as sure as possible when I buy them. That hook appears to be around 8" or 9" tall and has a slight shape difference.

Kevin,
If you found a source for the complete assembly with hook that are original I would be interested.

the cckw hooks are about 9" long with a 1 1/2" eye hole 3/4" thick. the chain is 1/2"
they where made by crosby
i like this size but i haven't found specs in the halftrack manuals for the original hooks.
some stuff on ebay.

these have 3/8 chain and smaller hooks so they are not correct

Hey all,
I am working through a wrecker operator I know so not sure how old these are. He is bringing a sample to me. I hope in two weeks. I know the original winch chain and hook info is sketchy but just wanted to have a consensus regarding the size of hook. The 6.5 x 10.3 w/ 1.75 hole seems large for 1/2 chain but it does look correct when compared to original photos. I only have a couple winch tracks and pretty sure the winch line and hooks have been replaced so I cannot use them as a pattern.

Any source for the "cable clamp" that looks like the ones on the Halftrack and CCKW cables?

Interesting timing on this post coming up! Last month I had to load a 1954 M-245,thats a 35,000 pound 5 ton 6X6 aircraft recovery truck, I tried to use the yard truck to pull it out of the hole it had been sitting in for the last 20 years,but those old 7.50-20's just couldn't get any traction in my soft sand,I even tried a snatch block and the winch to get it moving and it just slid the whole truck,so as usual out came the half-track,it had no problem dragging it out,then came the fun part,loading it onto the flat bed,the outside wheels were the same width as the bed so it had to be lined up perfectly,but these trucks came with power steering,and like all vehicles with power steering when it isn't running it's much harder to turn,we used the CCKW to run the truck up the onto the bed but it was about 6 inches off kilter,I tried to use the cckw to slide it over but again it just slid in the sand,so I tried to use the half-track and just dug huge trenches,so I turned the half-track around and hooked up a snatch block to the bed side and the hook to the truck, no problem she slid far enough to make the load legal and get that monster out of my yard!
I check my welded links afterward and could see on signs of cracking or fatigue, when I welded them I ground then out to a deep V and used my arc welder to weld them closed,since that was the biggest piece of equipment in my yard I shouldn't ever have to move anything bigger!

dont know about other stuff, but this outfit made the leader chains for Dodge WCs during the war.
