Military Tractor Pix

Found military site with pix of several tracked tractors that may be of interest to some here, ie: fixerupper (M4 AC's), Lavoy (Cletrac M2 High Speeds), several IH TDxxs, and others. Enjoy!!
poke here

Thanks for the link. Went through it four times. Didn't see the M4 High Speed but there were a few in there that I've had wrenches on. The amphibious looked a little like a DUKW but more modern. I replaced the transfer case in a DUKW. You drop everyting in from the top. If you need a wrench that's on the shop floor you crawl out, go down the ladder and crawl back up and in. It has a zillion U joints. There's a propeller shaft between the tranny and the transfer case, separate drive shafts to each rear axle clear from the transfer case to the axles. Drive shaft from transfer case to front axle, drive shaft to the prop, drive shaft to the winch, and lessee, I think that's about it but added to that are quite a few carrier bearings with U joints at each carrier. If I remember right there are thirty some U joints to keep track of.

Replaced the rod bearings in a MASH ambulance Dodge powerwagon and a couple of M38 Powerwagons too. Did a complete resto on a 1942? WW2 Dodge 1/2 ton Command Car, A 1944 Ford GTB'Burma Jeep',1941 Ford GPW jeep,1944 M-4 Autocar half track and the 1944 High Speed Tractor. I'm not doing anymore for awhile. Too much of my own stuff to catch up with now and I'm not getting any younger. Jim

We set up one of those amphibious DUKW's on a stationary dynamometer. We removed the prop and had the machine shop to make an adapter to fit the prop shaft. This was back in the 1950's. One of my former Army buddy's has a Dodge ambulance. He had a Weasel and a GMC truck it had a hydromatic tranny. Hal

The DUKW had a Chevy six for an engine but I don't know the cubes offhand. I did replace the engine in a Weasel too, I forgot about that. The Weasel was made by Studebaker. There is just no room to work beside the engine and if you drop a wrench you grab a magnet and go fishing down there. You can't get under it because the Weasel is made to be able to float. It's a neat, smooth running little vehicle that'll float on about anything and it's as quiet as a whisper when it runs. A lot of Weasels went to Norway and Alaska. The one weakness is it'll climb a pretty darned steep slope and then the engine starves for oil and spins crank bearings. Did I hear somewhere that Studebaker engines tended to do that anyway? Jim

Jim, if you go to "search by category" dropdown box under picture area and scroll down through "tracks", you should see a section toward the end: tracks-tractor-M4HST----Just above engineering section. (17 pix).
Also has caption on/off feature under pic--good info.
Been thinking about a M116. Thanks to all for comments.

I think they used a GMC engine that's was similar to the Chevy engines. We received a LARK to replace the DUKW. The LARK was lot faster and it took an experience driver when picking up people in the water. We ran a lot of amphibious tests on Army vehicles including power boats that were used for setting up bridges. We ran fuel consumption tests in the water and measured speed. Nice to have a job you loved to go to. Hal

Oh yeah, thanks for explaining how to navigate the site. It's on my favorites now. I could spend hours with it. Jim

It was spelled LARC and here's a picture. Hal

Here's a different view. They were also very fast in the water. Hal

We tested both the M114 and the M116 and both used the 283cid Chevy engine. This was back in 1960's. Hal
