Working with a member on his A0 brakes. Considering deleting the Load Sensing Valve since the A1+ trucks including my A1R don't use it and seemingly have no issues without it. Here's the A0 pneumatic diagram and the A1R pneumatic diagram. It would appear they simply deleted it. The later...

My engine mounts were shot. And every other truck I've looked at was in similar condition. Speaking with someone in the know - apparently even Acela doesn't change these. 2008 M1079 w/25,000 miles. Before. You can see the "fretting" from vibrations that is causing that characteristic red...

This is the correct FMTV cab support tool for working with the cab up, but not fully forward - in cases where you don't really want to unload everything and prepare for full forward cab tilt. This is part of the FMTV special tools kit that every Army unit with FMTV's is supposed to have at least...

I've been fighting my air system not holding (perfect) pressure overnight since I bought this truck in '21. Even after fixing every leak I could find, the pressure would drop overnight - depending on ambient temperature - usually from full tanks to about 60 psi but at times if it was fairly cold...

M1009. Was in a sorry state when I got it (and still pretty rough). Hadn't run in a while. Showing 8,400 miles on the odometer. Replaced all the battery cables, rebuilt both alternators (one had a shorted regulator, the other had one brush lead that turned green and fell off) - they came apart...

For convenience of the soldiers, the PMCS portions of the -10 manuals have been digitized and QR codes produced so they can simply scan the code on the dash of the truck and go through the PMCS using their phone. I present them here. You can print, laminate, and post it somewhere on your truck...

Those of you who have not driven an A1R or A1P2 probably will not understand this post. The C7 trucks (serial #100,001+) including both A1R and A1P2 have a different air brake pedal valve and if you have driven A0, A1, and A1R you may have noticed that the A1R trucks seem to have a brake pedal...

I got this M1009 unit running and first drive - no shift out of 1st gear. Got 20" of vacuum from the pump. Nothing from the regulator valve. I took it apart and cleaned it up - did get it to function at least a little bit by unscrewing the top to put more tension on the spring inside. Got it...

https://www.jegs.com/i/JEGS/555/511457/10002/-1 Picked up a new problem child - there's a giant hole in the radiator and someone soldered up about three rows of tubes. So I'm looking at options - this is the only one with pretty detailed pictures and appears to have the trans cooler, engine oil...

I've seen a few questions posted about replacement canisters - which are a bit difficult to find and expensive on the surplus side. I recently replaced the diaphragm's in all of mine and other than dealing with the paint on the clamp bolt threads it's an extremely easy process. On my 2008 A1R...

I replaced the ECM to engine wiring harness on my 2008 M1079 A1R due to multiple occurrences of connection issues with all three of the pressure sensors - the oil pressure, boost pressure, and atmospheric pressure sensors would throw codes and the boost pressure sensor in particular would put...

Well this is going to make a few people (including myself) feel really silly...... I've been getting pretty deep into a CTIS diag on a friends truck and had the occasion to swap modules between my truck and his, and vice-versa. And I've been going over documentation and troubleshooting info and...

Swapping out my small windows for something more suitable to it's new life. Got the door window installed and the passenger side wall upgraded. I'll be masking the glass and going over the outside with CARC so they look factory. Might figure out some drop down canvas covers for them as well.

Ok I'm *almost* ready to charge the system. The only remaining question/discussion I would like to have is regarding the system capacities. The TM lists the capacity as approximately 4 lbs. I'm told by someone that has installed a number of these that it's 3.75 lbs. I can go off system...

Has anyone encountered one of these?

Get out there and service your dryer. Less than 1 year on this cartridge. Drain my tanks weekly (never any moisture I can detect), and daily drive my truck:

This is the latch used on the PDP panel cover. I sent them an email asking if the spring steel safety catch is available on its own (both of mine are broken) but even if it isn't the whole latch is only $10. https://southco.com/en_us_int/91-562-07

The parts reference spreadsheet only lists the Stant AA02516 - this being a military part number without any cross-reference. Doing some digging around it appears that a Stant 10230 is a proper fit and is stocked at nearly every auto parts store in the USA. Autozone part number 7016 (it's a...

I'm considering a pair of these. They come with shunts and are 12/24v and they are relatively inexpensive. One for each side of the 260A alternator. My main need beyond monitoring the draw on the stupidly expensive alternator is to ascertain how much overhead I have to work with on the 24v side...

This is an annual service item and I'm not finding any availability on the civilian market. It's a Bosch filter: NSN: 2910-01-375-7624 Part number: 3032141112, or 3032.141.112-0CB I have a surplus filter but curious if anyone has found a cross-reference that's commonly available.
