What fluid is compatible with the OE/HDO 10 spec for the transmission fluid? Thanks.

On the passenger side top of the transmission where the air lines connect to the transfer case - air is blowing out between the the connections where the lines go into the top of the transmission. Any body know what is wrong? Cannot operate the truck anymore.

Can someone point me in the right direction for the wiring diagrams for the M920 - that shows the solenoid for the transmission. Thanks

All of the sudden when I cut the headlights on, the truck shuts down. It seemed like a short circuit, the volt meter pegs to zero (all the way left). I have spent hours and hours trying to trace the issue. I discovered that my solenoid has melted (the one by the ether can on the drivers side)...

I have an M917 and am looking for advice on the air shift front axle/diff lock. Has anyone had any issue with it not engaging?

These were just bought from Gov't Liquidation. They are brand new. They will not fit the M800 series or the M900 series. Anyone know what they go on? The bolts holes are smaller and are not beveled; and the hub size is larger (11").

Tried to put 22.5" super single rims with 445 65 22.5 tires today on my M916 today and the rims would not fit over the brake drum. The stock rims are 24". It looks like others have super singled out the front of a M916 or M920? What rims did you use? Thanks

When installing a new airpack, do you bleed the system with air pressure in the tanks or not? Does it make a difference? Also, do you need to air air tool oil to a new one? I installed a new one and my brakes locked up. I know I bled the system completely. Cost a fortune in DOT5. This is...

Installed a new air pack. Bled the brakes (engine off, no air pressure in tanks). Drove truck, brakes lock up almost right away. Released air pressure from the service line (lots of built up pressure) so I could move the truck. I have missed something. Do I need to bleed the top bleed screw...

On my 916 the interaxle differential works, but the front axle doesn't pull. On the transfer case - there is a slight amout of air constantly coming out of the breather fitting. The light comes on an off inside the cab and all sounds normal, but front axle does not pull. Any ideas? Is the...

Just took delivery of a M916. It is my first, sold the M818. Anybody have a link to the tech manuals? I need to sit and read and figure this truck out. Thanks.

My M817 front axle does not dependibly pull. It just started a couple of weeks ago. When it does pull, it pulls well. No odd noises, etc. Any advice on what it could be? Is there any specific maintenance item I need to look at? I have to put it in first and then reverse and then first...

Need help. Any advice on parts for the drivers side landing gear? I need the major bolt - thread style rod that raises and lowers the leg.

Got an M172A1 for my M818 to haul my excavator. Where can I find manuals or information about the trailer?

Need some help. Broke a lug bolt on the front right today. What do I have to pull off to get to the back to replace it?

Is there an adjustment for the brakes? I have been hauling for some time and the petal seems to be getting closer to the floor.
