Model's are A1(R) and A1P2 - actually the military doesn't officially recognize the "A1R" - it's just a late model A1 in terms of the EMS-NG system - but some documentation including PS Magazine articles and some of the schematics mention it so it's kinda stuck. A1P2 is the "phase 2" which are...

A fellow member mentioned to me that he had a family member that owned a tire shop and got them for a little bit less than is shown in that ebay ad - but not much. The military gets huge volume discounts - in fact if it weren't for them the factory making these wouldn't even have a market to...

Well that appears to be the original 1997 MD3070 transmission - which was originally either a WTEC II or III. The transmission control module and the shift selector is for the WTEC-IV 3700SP transmission used in the A1R trucks starting with transmission serial 6510653277 and later. The two...

He is referring to the torque changing due to the addition of lubricant - which it does. Unfortunately without actual testing of dry vs. lubed using a dial indicator to check stud stretch it's impossible to say with much accuracy. Probably easier to clean the anti-seize off and reinstall them...

That video from Michelin makes it sound easy - having experienced a front right sidewall failure on my DOT 2008 Goodyear MV/T's - the amount of sidewall on these tires and how far the truck drops on that one corner is ALARMING and the violence of the shredded rubber not evenly rolling under the...

It's an all-day job to do 6 of them for sure. Not as hard as that video makes it out to be if you have the proper tools - primarily you need the Ken Tool slide hammer bead breaker: https://www.jbtools.com/ken-tool-35926-heavy-duty-impact-bead-breaker/ This makes short work of the bead and is...

Tires are a HUGE concern especially if they are that old - judging by the mismatched rim colors this has already been a problem for it. If you lose a steer axle tire on the interstate you will, in all likelyhood, die horribly in the roll over and potentially take other motorists with you. IMO it...

The governor both unloads the compressor (it sends tank air to the unloader pistons on top of the head and these hold the intake disc valves open), and controls the dryer purge at the same time. When wet tank air pressure drops below the governor set-point it vents the air from the unloader...

My M0179 A1R with ECO hubs gets a little over 10 mpg if you drive careful with cruise control (yes it has electronic cruise control through the CAT computer) and kept to a reasonable speed. The 7.2 Liter C7 CAT engine runs about 30psi through a Borg Warner S300. The FMTV's have tons of support...

900 series trucks were damn good. But can't match the FMTV / ECO hub combo for fuel economy. But damn I do love me a 916A3 Freightliner..... The 900 series trucks don't have any significant edge in terms of parts availability to the FMTV - there's plusses and minuses in both categories. The...

M35's are great - for parades. And if you want the engine to last any significant amount of time you will run primarily diesel in it - all "other" fuels were emergency authorization only. I worked on and drove a lot of those turds (52D Motorpool vet) and the FMTV replaced it for GREAT reasons...

If the pressure is up and the system isn't activating you can just insert a jumper wire between the two pins on the harness connector for the pressure switch at the wet tank and that will fool the controller into beginning it's pressure check/inflate/deflate cycle. Most of the time it's a wet...

Well that's interesting. Looks like poor connections at the alternator may have caused excessive heat and a fire or the alternator was short circuited or something. You can check the alternator carefully with the troubleshooting guide but I would expect is is probably toast. Before you attempt...

Aftermarket throttle controllers are "piggyback" devices that attempt to fool the ECM into believing the input has changed in some different way than reality. Be very careful with such things. Not only can they have unintended consequences, but the prosecution will crucify you in court if you...

The only time I've seen a seal messed up is from improper installation of the hub onto the spindle. And usually they have no idea till it's in operation. Seal driver won't help with that. Not opposed to them - but if it's more than arms reach away I'm not going to bother for this application...

What you need to pay attention to is lifting the heavy hub onto the spindle so you don't cut any of the seals. If you really want to play engineering then design a fixture for holding the hub and centering it on the spindle as it's being installed. I've seen lots of 18 year old kids do this...

Yup. Don't need any seal drivers. This is an Army truck not a Space Shuttle. Whack it in with a hammer and be done with it. CTIS seals can be installed with a large flat blade screwdriver - just keep to the edge of the seal so you don't damage it. I've done enough 3D printing to have put...

Ok! Will do that tomorrow and report back their answer!

Most of the failures are due to both over-filling (common problem in the Army - aerated fluid compromises lubrication properties) and the tendency for people to change the fluid in response to transmission behavioral issues that turn out to be transmission failures in progress - they then...

I can't find a Champion radiator listed that's even close to the stock CUCV radiator size. The largest radiator they list is a 33" wide unit. The CUCV radiator is 41" wide. Unless I'm missing something on their web site.....
