I attached the lube order for your truck. According to page 2, the multifuel takes OE/HDO 30, which I think is 30 wt. Others can probably give you better guidance.

It's my understanding that the problem with the AT1545 on the M35A3 is that it wasn't really designed for the loads the truck was designed to operate with. The GVWR of the truck is around 19000 lbs, going up to about 25000 lbs GCWR. The truck's GCWR is actually a little over the AT1545's load...

The main weakness I've read about the M939 trucks involves low range and reverse gear - just don't give it too much gas pedal :poop: Also it seems the fuel shutoff solenoid likes to stick closed. I think the Cat 3116 is a good motor. It has seen wide application from 150 to around 700...

Yeah, there's mention about it in the LO, the TM, and some posts here about maintaining it. My understanding is that you can go a few thousand miles between PMCS with it though, like everything else on the truck (the LO says to check bearing nut tightness and lubricate every 3000 miles). I...

One of the things I want to check on my truck sometime soon is the rear suspension spring seat. I've seen horror stories on here about that spring seat bearing getting out of adjustment and stripping the threads right off it. A good chunk of the rear end has to come apart to pull that piece...

That's a great-looking 5-ton :cool: I hope you find it a nice home! That said, I've seen drivable M54 trucks go for between $5k and $15k. I agree with @98G that this truck would probably be near the top end of what I've seen considering its condition.

I remember looking at that listing. That seemed like a nice truck! I wish I could've put an offer on it but my wife needs another minivan more :rolleyes: Though she likes trucks painted in desert tan!

When I did my tire replacement I discovered gear oil leaking from three of my rear axle hollow studs. I plan on doing the seals this spring, but I'm wondering now: could a malfunctioning CTIS power manifold cause blown seals? The CTIS ECU on my truck doesn't turn on and the wheel valves are...

Maybe there's too much moisture in the system and it's freezing the air pressure sensor in the manifold? Maybe the air dryer needs to be serviced. Just a guess - I've never had mine apart as I've removed all the CTIS wheel valves from my truck and the system ECU never worked for me.

Nice project! I never realized how much the MTVR dwarfs a commercial tractor cab o_O

I took a closer look at the rim. I think that would go on an older 5-ton since it only has ten clamp ring studs on it - probably came off an M939A1 or A2. I think the FMTV wheels have 20 studs. Looks like you have NDT, Michelin XML, and XL tires there.

The one wheel looks like it goes to a 5-ton or FMTV - ten stud holes there. Three kinds of tires there too anyway.

They need to realize that "zero" is a digit and add them to the VIN :rolleyes: I think that's what NY DMV does in their computers for older vehicles.

I appreciate your attention to historical detail! I wanted to maintain the CTIS on my truck for the same reason, but I don't have the time or budget to keep it up. Good luck with your project :)

That's funny - the wheel weights on my M35A3 weren't consistently installed in the right spot either. The TM doesn't even have words to specify where to put them, so I went off the illustrations and my best judgement relative to the position of the CTIS valve. That was shortly before I decided...

What are common rust locations on the HMMWV? The only things I've read about so far that really seem susceptible to rust are the frame rails and the wheels, but I get the feeling there are other places too despite the aluminum in these trucks. Are there other rust locations that occur when the...

When did this end up in the HMMWV forum? :giggle:

The red part looks like an add-on. I think that truck should have a PTO-driven pump, though if it isn't working it would be easier for some to just attach another pump and hose.

Super singles are easier to handle than I expected, which was nice to find out! The OP seems to be dealing with duals and wants to remove them as duals.

If you go the pallet jack route, make sure you get one with wide enough forks to capture the wheel without having to jack up the truck higher than you need to. The one I got for free was too narrow to support a 46" super single without jacking up the truck a couple inches higher than I wanted...
