The platform is made to raise/lower. Aluminum hull, V8 gas engine and what appears to be an Allison transmission. I am thinking about buying one to make it a tank look-a-like.

No idea. So will a Ontos top fit on it?

Looks like a XM474E2 Pershing Missile Carrier chassis. Wehring has one and it is a blast to drive. 75M Chrysler 361 engine, Allison Trans, Allison Cross Drive, all from the M113.

I told you NDT was the man to talk to about it. Good deal.

Bought both of them, hopefully going to have them hauled home next week. Going to attempt to sell the one in the back of the above picture, but I kind of want to keep it and get it going too so I can have TWO.

Yeah I see your reasoning behind buying them now. The lower half of them does look just like any generic tank hull. Should be an easy, but probably pricey build. Are you going to use aluminum plate or AR500?

My PLAN is to build one into a tank, and the other into an APC. Hopefully I can get the M75 running that is already in the one, and put a 5.9 cummins in the other one. I have thought about building an inner frame structure out of steel tubing, then skin it with plywood for awhile. I would eventually replace the plywood with AR500 steel as aluminum would be VERY expensive. 1/4" AR500 would stop basically all small rifle rounds, especially if there is a 'slope' to it to deflect the bullet. I think the tradeoff of using 1/4" and having weaker 'armor' will be a good tradeoff for the cheaper cost and lighter weight of 1/4" vs. 3/8" or 1/2". Not like I plan on ever NEEDING the armor anyways.
The first order of business on these will be to strip ALL the hydraulic components that were used to raise/lower the platforms, I have kind of thought about using those hydraulics to put a dozer blade on one of them.

The engine orientation will make for swapping in a different engine/transmission, but will definitely be a big hindrance on space savings.
I also do not think these are the M474e2's like NDT thought, they are some sort of aircraft loading platform, I am not sure of the model number though.

Agreed, wrong ID on my part. Undercarriage is 113 though.

OK, finally redeeming myself on the ID. Found your track listed on page 384 of the Crismon book "US Military Tracked Vehicles". It is a A/S32H-12 Aircraft Cargo Loading and Unloading Tracked Truck. Built 1964. The suspension could be raised and lowered as well as the platform using hydraulics. At the lowest point, the hull would be 2.5" off the ground. The original "lowrider".

Awesome! That sounds like it might could be fun to mess with people with!

I just googled it, too bad I can't find any info on them... I wish I knew if they used the same drive gear housing and tracks/suspension as a m113 or not. If it is going to be one of those things that has 'unobtanium' parts on the suspension I will be a lot more likely to keep both of them.

The engine, transmission and cross drive should be the same as gas 113. The final drives are likely as well. The road wheels and track are 113. But the suspension is torsion bar only on the 113, whereas these must have hydraulic cylinders at each suspension arm.

After googling "A/S32H-12 " I don't see any tracked vehicles. Just some vehicle that looks nothing like these. Am I missing something with the numbers?

NDT, thanks a bunch for the info. I haven't looked very closely at these things yet because I figured I would just dig in and start removing unneeded stuff right off the bat (everything for the platform) and just figure out everything else along the way. While they sat at the junkyard I did notice a heavy linkage down at the bottom of the hull that went from the front to the back on both sides, I am going to guess that was used for the suspension. I am going to GUESS it uses a torsion bar suspension like the M113, but that the hydraulic system would release pressure off the torsion bars to lower it down. I would guess that it could be bypassed completely, BUT it seems like a pretty cool option, although I am not sure what I'd use it for. Maybe make some side skirt armor that fully covers the track system (or all except the bottom couple inches) when the suspension is lowered, but would not interfere with off-road performance when suspension is raised?
I can't wait to get one of these things going....

Neil, if you search for "A/S32H-12 Tracked" you find a VERY little bit of info, there is something with that designation, but I have not seen any pictures of it.

wonder if the transmission will bolt up to the cummins I have? The cummins does have an SAE bellhousing, so just wondering if the torque converter and stuff will swap over? I also wonder what the gear ratio's are in this transmission and if it will limit my top speed greatly by swapping to the diesel. Does anyone know where to look for info on the Allison transmission?

I called Allison, but she wasn't able to help much, and she kind of sounded like a dude

The Allison automatic has a 1:1 top gear. Your road speed will have a lot to do with what the ratio is in the final drives. This thing could have a special ratio given it's purpose. Otherwise there are two ratios available, the M548 Cargo Carrier ratio and the M113 APC (faster) ratio. The M113 could do 40 mph.
