The problem is there is no voltage anywhere. I'm wondering if there is a wiring diagram somewhere I can access it. Thanks for the replies. Steel Soldiers has always been a huge help in the past.

I am hoping someone out there can help. I have a M920, the truck has less than 500 miles on it. I am having trouble with the engine retarder or "Jake Brake". Where or what do I need to check first? Thanks

Hi Everyone, We just got our 1985 M923. The front wheel assist is not working. We can hear the air valve working but it does not lock in the front axle. Any idea of what to start with first? Thanks for your help, Glenn and Judy

Hi Everyone, We are working on our M818. The front axle was leaking oill. We pulled the wheel and saw the seal in the hub but our first question is - Is there a seal in the knuckle? Also we would like to know if you need to pull the wheel to adjust the brakes. Help! Thanks for all your help...

Awesome, thanks so much for all your help!!

R Racing, thanks for the info...will do tomorrow. When you say to shift up to 6 then down to R2, meaning every gear until the oil does it's trick? How do we adjust our air governer? Also, how often do you have to add oil to your M920?

where do you put the air tool oil in at?

Here's our problem...The truck, M920, only has 200 miles on it. With the air shift CAT 7155 trans we have had consistant problems getting it to go into reverse. Now we are also having problems getting it to shift into the forward gears. It has always needed at least 120 PSI to go into reverse...

We are having problems with our CAT 7155 transmission and are thinking about swapping it out. What auto transmission will fit?

Hi R, glad to hear you are ok but sorry to hear you are without power. Did you receive any damage from the storm? Any help would be greatly appreciated. This M920 was rebuilt in 2008 and only has 186 miles on it. It make all the usual noise like all shift changes but will not go into reverse...

Hi R, well I did as you advised. The first time I put in 2 oz and then the remaining 2 oz. The forward gears are much better but the reverse gears are still a problem. It absolutely not go into reverse until at the air pressure exceeds 110 psi. Other time it just will not go into reverse no...

Hi R Racing, thanks for the reply. My truck has been painted and everything is green. Is it the line that comes out of the back of the tank directly under the driver's side door?

Hi, I just got my M920 home and am having some trouble with the CAT 7155 tranny. She will not shift into gear until at least 110lbs pressure and sometimes she just will not shift into gear no matter how much pressure. Geting into reverse seems the most difficult. Any advice? I'm hoping ya'll can...
