So let me begin with we were using the M936 today putting together the final drive on a Dresser DT15 and all of the sudden the truck tries to take off. The T-case will not go in neutral, even when it is in neutral. I got under it and checked oil, all is good. It is hot where you can't hold your...

So here we go, have some questions for all you transmission gooroo's. The 6 bolts that hold the flex plate on the engine came loose and let the torque converter eat its way into the transmission and messed up the seal on the output shaft. I did not know all of this at the time, I just thought...

So I am thinking about putting backup lights on the M872A1 cattle trailer because sometimes the sun goes down before we are done working for the day. Sometimes there is not a pickup to shine the lights on when needed backing up to a loading shute. So I ask how does one go about wiring it so I...

So the transfer case went out on the M936, well it is just a bad bearing. Getting it home took some time for it would not want to stay in low or high for very long. I had it up a canyon loading saw logs to make lumber. Driving it to the low boy was about 5 miles, but getting it home was another...

When using the M936 the other day the T case got hot where the short drive line come in from the transmission and started smoking. The truck did not want to move so I let it cool down and checked the oil level (Oil was good and has been changed not long ago) after letting cool down all was good...

Does anyone know what the Napa,Carquest, National # for the seal that goes on a TH400 transmission behind the torque converter? I have taken the old seal in to town to get one and the one they ordered was wrong. I am in kind of a pickle for I live 60 miles one way from town and I can't just...

We use our MEP's for pumping water for cattle, all wells have submersible pumps (3 and 4 horse) and every pump has a control box and on the bottom of the control box has 2 reset buttons. So here we go with the question, the ranch bought 2 MEP802a's and at one pump station sits a 002a with dead...

First let me say sorry for no photos, I never have a camera with me. But the good news is the Ranch bought 2 "new to us" CUCV's for ranch trucks. One I have questions about. I think someone tried to convert it to a 12V system, the slave wires are cut, the batteries are not wired in series, the...

Yesterday we were pulling pipe out of a windmill using the M936. The boom up and down did not want to respond as it should and noticed that the Hydraulic oil got hot enough to fry an egg on top of the tank so we shut it down to let it cool off. After about 5 minutes all the sudden she blew the...

So changing out the engine that came out of a M939 series truck into a M818 we put the starter that came with new engine, all worked fine with changing the front of engine. The starter was off the M939 series engine and it is dragging bad. Do I need to shim it back/out? It is fresh rebuilt so I...

So where to start? My nephew blew the engine in the M818, long story short, we got a new engine from Kansas (Glen) and it came with a Allison glued to it. I have both engines sitting on the M1061A1 trailer so I can put stuff that belongs off one to the other. We took the Allison off today so we...

I had a hydraulic hose break on the M936 and it drained all the oil out of the storage tank. Has anyone played with the idea of installing a ball/gate valve so if this ever happens again one could shut it off saving oil? Is the any maintenance that need to be done before I refill? Is it a good...

Would you all mind helping design a trailer out of a 1973 white tractor truck. The truck is being scraped out but this is my idea. I will leave all axles rolling on 1100-20's on the frame front axle included, what I need is ideas how to make the front wheels follow the 5 ton's like a M989A1...

The Ranch bought a M923 that had been sitting for who knows how long. Long story short the PT pump was gummed up (remind you of pine tar) the throttle shaft was so sticky that the spring on the throttle linkage was not strong enough to pull it back to Idle, so reaching down or pulling up with...

I have trouble getting a grease gun on the zerks on the short drive line that hooks to the engine (5 Ton), does anybody have a trick they would like to share? I have tried a needle with no luck, thanks in advance.

The brakes don't work very good when this little part went fubar on me, can anyone tell me what it is, and can I plug it off and get by or need to replace? It was located on the frame rail drivers side in between the fuel tank and back tires, it leaks out air only when brakes are applied. There...

Fist off I hope I am not beating a dead horse, if so I will take my butt chewing. I always try to win at least 2 gensets so I can try to make one good one. I picked the best out of the 2 latest ones I won and got her running. When I first started it it was overcharging voltage big time, 1st...

The winch on the boom went to leaking hydraulic oil when running and or lifting. It runs out so bad that it is coming out of the vent cap on top of the winch itself (not gear oil). Is there a seal that keeps the oil from entering the winch from the hydraulic pump, if so how hard is it to change...

So let me start by saying that I did search for all problems and with no luck have I got my M35A2 running like it should. It has been at the mechanic shop for 2 years (he lost interest in it and gave up) so now I have my neighbor helping me that is a great mechanic but we are stumped. I bought a...

The PT pump in my M936 is leaking bad (like runs out on the oil filter canister) where the throttle shaft comes out, I did my research and seen that I have to sent it to Cummins to get rebuilt, but my Nephew (bless his heart) blew the engine in my M818, and it ran like a champ. Can I take the...
