All of the CTIS boxes are 24 VDC - indeed the M939 has only 24 VDC systems so I'm not sure what SUPPLIER 16V is in reference to exactly. Nothing important I would say. I have the software on my google drive because no one can seem to find the Dana download for it anymore. It's only 8 Mb...

Check the filters? Perhaps the fluid is too thick when cold and not flowing through clogged, collapsed, or damaged filter elements? I would get the 15w40 out of it and put in Dexron ATF. The military stopped using 15w40 in the FMTV's and the ATF shifts better.

Yeah doesn't look like there's any habitat suspension or articulation capability. Looks like any off-road would destroy the house in short order. Aux cooler would be better between the frame rails with fans that push air into the low pressure area under the truck (ground effect).

What did you for isolation between the box and frame? With the frame that long there's going to be some flex and you don't want to destroy the box.

It's pretty much the same as the power steering - suck all the fluid out of the pump, refill with proper fluid, exercise all parts of the system as much as you can and then rinse repeat till you have changed what you figure to be about 1/2 the capacity 4 times over, or about 2/3 of the capacity...

It's not that bad...... System only takes about three quarts so this $30 gallon jug will do the job. Get two and have enough to properly flush it and some spare on hand. Republic Oil 5606 Super Clean Hydraulic Oil 1 Gallon 5606A 5606H 5606J https://a.co/d/475npWk

The cab lift system does not use AW32 hydraulic fluid. It uses MIL-PRF-5606H mineral oil aviation hydraulic fluid. AW32 and ATF and all the other stuff that people put in there is part of what causes the seals to fail and clog up the cylinder check valves, etc. 5606H has an ISO 15 VG - it is...

Jack up the front with the wheels off the ground, suck out the reservoir, refill with new fluid, and steer the wheels lock to lock a dozen times. Repeat this process two or three or however many times you like till the fluid you suck out looks like the fluid you put in. It's cheap AW32 tractor...

That need will come up again - run a fuse panel off the 12v ignition relay under the PDP for accessories.

Yet another example of MWM's turd polishing practices. They don't equip the trucks with the right parts - they equip them with what returns the most money. And the AD9 can be found all over for dirt cheap. It's new and shiny and that's all you need to lure a first time buyer. Acela is the same...

If they are anything like my steering tie rods and drag link they will pop out with a couple good smacks on the housings, etc. The TM just says "remove two self-locking nuts" and "remove torque rod" The prescribed tool list: General Mechanics Tool kit, jack, jack stands, goggles, torque...

Ah I see. You are too light in the back. Makes sense.

Maybe! These things have SUPERB traction due to literally tons of weight on a massive contact patch so it's pretty hard to lock up the tires. Put the tires at 90 psi for the attempt.

If you can get the ABS to activate on anything less than ice or snow my hat's off to you sir.

My guess is someone hooked up incorrectly or applied power to the coms port and blew those resistors. Your DC meter readings on the coms bus is showing the meters averaged interpretation of the 5v square wave. It's not going to be exactly 2.5v because the on and off times are not exactly 50/50...

That part doesn't exist in the Army system. That doesn't mean it's not the same but that CAT part number has no National Stock Number cross.

No a gimmick. A band-aid for a poorly sized alternator.

The original one with all the individual wires is a known issue. There's a PS magazine article about making new small interconnect wires for them. But there's a new version from Bussmann if you don't want to delete it.

So what symptoms are you having when you try to run an inflate or deflate?

There is no need to retract the cylinder. Once the cab latches and the pin retracts you can stop.
