I have an oil leak and it is coming from the open hole at the rear of the oil pan. It is a threaded hole. Am I missing a plug? Is this a vent hole? And last but not least could I have a rear main seal leak? Thanks guys!

I finally got around to replacing the gaskets. I did not pull the bearings, they still had a lot of grease in them so I just pumped some more grease in them with the gun and buttoned it back up with the new gaskets. The gaskets were a perfect fit......AND CHEAP. Thank you!

I agree! I snapped my left one in half!

I went with 2 group 31's. 1170 cranking amps each.

Like Simp I drive my M925A2 a LOT but it is working pulling a load regionally. 100-300 miles 1 way multiple times a month. In the winter it sits a bit more but still gets driven.

It is a pain to pull the bearings and repack them but worth it. You will need the 2 axle nut sockets. Use either blue marine grease or red n Tacky. There are videos on YouTube to walk you through it.

First thing I would recommend you to do is pull all the wheel bearing and re-pack them! It is very common that at least one has been put in DRY. I found out the hard way! Then go through and replace all the filters and fluids. Just a tip to save you a massive headache down the road.

Fyi those solenoids SUCK! You can completely remove it and just use the emergency shut off to shut down the truck. They are over $100 plus shipping and prone to failure. I removed mine and it has been off for over 6 months. No issues. I actually like it better this way.

Don't have Fakebook. Can you upload to YouTube?

Thanks Simp!

My M322 trailer is starting to leak slightly around the axle flange gaskets. I figure it is time to re-pack the bearings. Does anyone know the part number for the gaskets and would Napa have them? It is a Terex trailer so I thought that they might. Thanks

I had the same problem. There are direct replacements on army truck part supplier sites. Very easy to swap out.

How much power did you add going all the way out and is that too much fuel for a heavily loaded truck?

What is the normal operating EGT of these trucks and what is the max sustained EGT before getting too hot and damaging the motor? I have the gauges, just need to install them.

I finally fixed mine. I had no idea how bad the muffler was. Rotten all over. So much quieter now and have the stack on. Putting a pop cap on it to keep the water to a minimum to prevent a repeat.

Mine rolls at 60 at WOT fully loaded, it is just slow as molasses on a cold winter morning on hills. I really want to just be able to run 65 with a 70 sprint. Honestly, my goal is not only to get to where I am going faster but to hug the rear of another truck and let them push the wind and...

I am getting the itch to buy a M931A2. Does anyone know the towing specs on this truck and will civilian trailers mate up with it? I need a lowboy 40 foot trailer behind it. Thanks guys.

Even with fuel turned up?

Exactly.......but I WANT to tamper with it....lol.

How do you get the tamper proof screw off the back of the pump? I am about ready to get into the pump and turn it up a tad.
