Holy crap. My wife's cousin farms hogs. One day, the boar abruptly copped a major attitude with her and probably would have killed her had she not ventilated his skull with a .357 she carries. My point being that I'm glad you made it out OK.
My bad, I should have explained a little better. The pigs we have are Guinea pigs. I reread my post and realized I wasn’t clear on the pigs I was talking about. Two of my wife’s male Guinea pig’s got frisky and were beating the daylights out of each other. I thought they were going to kill each other. So I stuck my hands in their crate to separate them. It was a mistake! Them little buggers tore into me like a tornado in a trailer park. Got cuts all over my hands as well as a deep puncture wound that required 5 stitches to close. It’s still leaking ‘cause one of them nicked a vein.
Sorry for the confusion.

Finally got to work on the M52A2. The wiring is a real pain to figure out. Fortunately, I found TM 9-8028, which has a fairly complete set of wiring diagrams. Much easier figuring out which wire goes to what component.

Not much to report. Still trying to figure out the fuel pump wiring. Also got to figure out how to insert a small light in line to the aux pump. No wiring data for that. Got the engine shut off lever installed. What a pain. Still in work getting the throttle lever correctly installed. I think I’ve got it figured out, just need to route is as good as possible. Pics show the engine shutoff and throttle linkage. Not much room to work with. Now would be a great time to have functioning wrists.3B2D2DD1-2E1C-4E4F-B1DE-0C423E71CC7D.jpeg4E21025A-B17D-4E88-ABD2-3248805BB7DB.jpeg5803A00F-39D1-4E73-B485-05B90B472835.jpeg

Jeff,

I am not a truck guy, but if you want to insert a light in the same cuircuit as the AUX pump, I assume to let you know when the AUX pump is in operation, its easy. Pull the electrial connector to the AUX pump. Insert a "Y" connection to the PLUG side. The hook one of the "Y" legs to the AUX pump, The other leg gets a wire that runs up to the dash(if thats where you want it) and hook it up one side of a add on light socket. Then the other side to ground. When the Aux pump comes on, the 24 VDC Path to pump (and light) will be completed.

This will NOT tell you when the pump fails. The light will ALWAYS come on, when the AUX pump is turned on. To wire it up so you can see when the pump fails, you need to put the light in series, BEFORE the Aux pump. Hot wire comes from the source, to one side of the light, out the other side and then to the pump. When the pump runs, the light is lit. The pump provides the path to ground. If the pump fails, (shorts out, burns up and so on) the path to ground is broken and the light will not illuminate.

Thank you very much! I’m a passively good at mechanical issues. I’ve never been very good at electrical stuff.

Time for an update:got all the wiring installed. I’m having to go back and de-bug some of the connections. Yesterday I confident that I could attempt a start, so I powered up and hit the start button. It took a few revs to kick over but she ran okay for a truck that been sitting for years. Today when I opened up the engine compartment, I found the air pump fan belt broken. I’ve never seen one snap like this one did. After digging through my stash of fan belts, I found one that should fit. Hope to have it replaced by tomorrow. If it starts, I’ll try a short drive. I still don’t like my aux pump light. Instead of the light coming on only when the pump is energized, it comes on as soon as power is applied. Turn on the pump, light goes out. Very confusing. o_O

Draw a picture of how you wired it up. Lets take a look see.
Thank you, I will get one drawn. I need to get that drawing posted. So much to do...

I haven’t gotten enough time as yet to do an in depth troubleshooting. Once Toys For Tots is over for the year, I’ll focus more on getting “The Beast” up and running.

I stumbled upon some books on the 5 ton series and strongly believe that even a pig can't argue about the details in these books. Let me know if you need anything.........I have versions in both French or English. How's the healing going?

Plowboy,

I stumbled upon some books on the 5 ton series and strongly believe that even a pig can't argue about the details in these books.

Mostly it not a matter of not enough, or not clear enough info. Its a matter of taking the time to read it. The first few years in the Army, I read very little. Later, when I got smart and read, I was simply blown away at the amount of information. And when I started reading everything 2-3 times, it was like a light popped on in my head.

We had some nice weather so I took the opportunity to get the 5th mount closer to being attached. The original 5th mount had a set of adapter plates, which gave a solid mount to the frame. In an attempt to make stuff work, I have a 800 series set of plates and, along with the hitch, a set of 900 series plates. I was stumped getting everything to line up. Pretty much the only way I could get it to work was by putting holes in both sets of plates and the support base for the mount. I have some drill bits that would work but they were filer than my jokes. Plasma cutting was considered but due to labor costs, I had to find another way. I decided to get two 5/8 inch drill bits. They had what I needed at Menards. Using some cutting fluid I got somewhere, that drill went through the steel plates like a knife through butter. I’ve bolted to plates to the base and when the temp goes up again, I’ll get the holes drilled into the base. After that, put everything together. Pics will be posted soon.

I don't even own an 800 series but I found a huge stack of working manuals at a wrecker and scooped em'.

PC020467.JPG

They were in a wrecked gubermint truck and I suppose someone was cleaning out the mechanics desk and tossed them. The capacity charts, lube charts, dimensions and pictures are always handy.

I’ve got a bunch of the digital TM’s for the 800’s. There’s a bunch of similarities between the M39 series and the 800’s. The 900’s are completely different.

Update for today: got the 800 and 900 series adapter plates drilled and installed. Also got holes drilled in the big mount plate that all other parts are bolted to. It took an excessive amount of time to get everything just right. Everything is now installed and will be bolted down tight as soon as weather allows. As I finished after dark, no pictures until tomorrow.

Pictures of the installation of the fifth mount. In the 4th picture is a close up of the stack. The 800 series plate is against the frame. Since the frame has raised rivet heads, I reamed out spaces in the bottom of the plate so it can fit snug against the frame. The top plate has two spacers(?) installed that the plate rests on. The only way I could figure out how to make everything fit was to keep the 800 plate and add the 900 plate. This gives enough space for everything to fit correctly. I have the two frame rails that I’ve been hemming and hawing on whether to install them. I’m thinking it’s a good idea to install them. It’ll give more attaching points to the frame. In the off chance I ever find a trailer I can afford, having everything bolted securely is the best plan.

That truck is such a beast. It's going to need a trailer to slow it down. Fortunately, we're expanding the wheel choice up here and polished aluminum is the new camo. Now you can blend in with the fleet with anything. Thanks to cmv dm for the photo.

There's a nice single wheel trailer option over here with a decent pic of the combo. Keep it up.

That little trailer would definitely fit the bill. Not too big, just big enough.
There’s a National Guard museum here in Cheyenne. They have a 155 cannon on display. I’ve thought of offering to tow it in one of the CFD parades. Not sure they’d take me up on it...
What kind of tank is that? Not familiar with armor except the M-1 Abrams and the M-2 Bradley.
