I think the automatic in the A3 is the weakest link. It's max load is around 26000 lbs, which a fully-loaded and towing M36A3 is reallllly pushing. Makes me wonder what the Spicer's max load is - has to be at least 24000 lbs.

An update: It appears the oil gauge troubleshooting instructions for the M35A3 are incorrect. The gauge is working properly- I just had to follow the M998 HMMWV troubleshooting procedure to figure that out :rolleyes: I'm not sure if this is just a thing with gauges going up to 120 psi. The...

We need more pics - that van looks nice!

I'm questioning whether the troubleshooting instructions in the M35A3 TM are correct now. I compared those instructions with the M998 HMMWV and the M939 5-ton: For the M939, if lead 36 is disconnected at the sender and the gauge needle deflects when lead 36 is grounded to the frame, the...

I'm looking for a new oil pressure gauge for my M35A3 and came across Federal Military Parts. I've never heard of them before and they advertise as a HMMWV parts and accessories vendor. Does anyone here have experience with them?

I'm trying to figure out if my oil pressure gauge is shot. The last drive during cooldown the gauge was reading under what idle pressure should be. Prior to that the gauge was reading properly with the truck parked and driving. I thought the truck was idling lower than usual, which could've...

I installed the new sensor today. I managed to start it in the threaded flywheel housing hole from the engine bay, running my arm underneath the steering shaft and squeezing my hand around a ground strap to get to the spot. After I got a good bite in the hole, I went into the cab and finished...

My dad with his leet trucker skills can do that. I haven't had enough experience with manual truck transmissions to pull that off!

Isn't the M35 transmission syncronized? Granted the syncros on @Redleg130 's truck may be worn to near uselessness. I've never driven a manual M35 - my A3 has a 4-speed automatic :p

I'd never put a vehicle in neutral to come to a stop, regardless in size. It's definitely a control issue. That said, with all the manual transmissions I've worked (from a 1999 Jeep Wrangler to a 1942 Autocar halftrack), I've found that downshifting by one gear or to the middle gear works the...

The big "C" on the valve cover that @porkysplace pointed out seems to be a good clue that the motor is a Cummins.

How many lugs on the wheels? It's a 5-ton if it has 10 per wheel.

My wife gives me almost the same argument every time I tell her I want a wrecker :p I had the opportunity to acquire a gasser 5-ton tractor-wrecker that had the same paint thing going on - yellow underneath camo. The Air Force used those trucks for wrecked aircraft recovery.

From what I could tell the speed sensor was never replaced before. I'm pretty sure it came from the factory like that. There's no maintenance interval for the sensor itself - just replace it when it's not working. I'm surprised as well that it worked for as long as it did! It makes me wish I...

3 years later the tach finally quit working. I decided to tackle it now since I think I have a low-idle problem to troubleshoot. Running through the TMs diagnostic instructions, I determined that the tach was okay and the induction sensor was dead. I think I see why it quit working... It was...

I definitely count - unlike the Army I can't afford to break anything :p

I've never started a multifuel motor - I have an M35A3, which has the stright-diesel Cat 3116. That starts instantaneously for me on days where it's 55+ outside! The multifuel TM says to not crank for more than 10 seconds: Based on that I'd say if it takes more than that to start the truck...

I know this is an old thread, but I've been looking up stuff about axle seals and wet bearings and couldn't let this question go unanswered. If there's oil in the hub, it will get into the CTIS components and gunk things up. That leads to wheel valves not functioning correctly. If a wheel...

You could just drive it with the windshield down - one problem solved!

Are you going to be trashing steering knuckle boots enough to need those? I'd consider getting zipper boots and replace them as needed.
