It's basically a one way valve so you have to take the pintle out of the injector at a minimum. Probably the nozzle and the guts of the unit for better flow. The pressure tester has a check valve. I haven't done this yet as my engine runs smoothly and hasn't called for me to do it (also I have...

Found the little compression fitting in my box. The part number is A-250610R2 a simple internet search: https://www.worthingtonagparts.com/injection-pipe-sleeve-to-fit-internationalcaseih-new-aftermarket-wn-250610r2?srsltid=AfmBOoqubpNGOVQgQ4PasCBBtB6_i5UbzBXVX44GH4tYOgvUKmFw6LBD Can't remember...

If you buy a pop tester off fleabay it's going to be an "India" type. That is to say, the land of plentiful Massey Ferguson tractors, type tester. If you've ever been to India/Pakistan/Afghanistan you'll know the whole place runs on these simple machines (and their simple injectors). IIRC mine...

There are enough surplus nozzles around that lapping new ones is cost prohibitive. You just buy new ones. As for cleaning and testing these are pretty low pressure (for injectors). You can buy a bench pop tester for a bit over $100 on fleabay and track down the adapter bits you need. I keep a...

OK here it is: SR5014602RD Many thanks to Wes for sharing the parts interchange page for the M939. You need to do that. Go to the M939 truck forum and click on the link Wes posted for the shared spreadsheet. He gave me access almost immediately after requesting it. @simp5782 you rock thank you!

Haha I'm being silly we should let somebody else do the research...

That's one of the spots the part number leads to. Not a lot of info on cross over.... Good one might take some sleuthing.....

From TM9-2320-272-24P-1, page 680. Looks like they are only listed as the backing, the liner and the rivets. No complete assembly. You can search for the NSN and part number on the web then comb the results. Usually you'll get crossovers, other manufacturers, etc... These are standard truck...

The little star adjusters? Clearance is 0.020" to 0.040" it's pretty basic. The wedge style brakes are different but really simple. I had to use a mallet to get mine off, rocking it side to side and striking it, but it wasn't anything abnormal. Just a 3# dead blow for a dozen whacks side to...

Dumb question.... you did cage the brakes before pulling the drum, yes?

It's in my shop someplace in it's project box.... It's really basic you have to break out power and comms from the plug. Problem is the plug is a solder cup style and the wires are quite small. I highly doubt you will be able to solder them into the factory plug simply because there's no space...

I have a couple "Force Protection" MRAP winch kits brand new in crates. I had to buy a lot of three to get one for my deuce. It'll yank the deuce all over no problem. Usually I'm in the cab with the engine throttled up on the brakes with the remote. They are pretty strong winches: 24V...

Looks like there's one hosted here: http://manuals.chudov.com/M939-Series-Trucks/CTIS-AXTS-0015.pdf The FMTV is the "flange mount wiring diagram" page 66.

Nice to see somebody do this on a bench. I made a "breakout harness" for my M936A2 that uses the same STE ICE components but on the truck. So I test and program on the vehicle. It's different for the FMTV I have to make another breakout harness. The pins are in different locations. I bought the...

Sounds like the CTIS is failing the pressure check. It sends a pulse to check and if the sensor sees it fall (when the pressure should be steady) it faults out because quite obviously there's a leak. Here's what I would do: -Get an air supply for the truck you can't work on it with it running...

Pull the pump and check it out. Mine was filthy but even after cleaning would only run upside down. Since it's really hard to drive the truck that way I needed a new one. Honestly the stock pump is a crappy design. Why replace it with the same junk? I installed a Walbro for half the price and...

I took the test in my M936A2 which weighs about 37k. For what it's worth the DMV didn't seem to care that the vehicle wasn't commercial. At the time it had Michigan Antique plates and registration as I was still in the process of getting CA Historical Vehicle status (I told them as much). They...

Yes my experience is with probably the strictest state and my particular experience in it. That said it may prove valuable or useful to somebody which is why I posted it. If you are exempt as a farm vehicle then yes you can drive anything over 26,000 pounds such as a HET (within certain...
