No not really. Just for looks. A few have cracked so a few days ago I pulled them off actually. What IS good are the silicone "powder coating" thread protectors I used on the wheel-half studs. Those are excellent. Amazon has them. 5/8" IIRC.

Oh yeah. The factory Red Dot AC system is the killer app for these trucks. That and ceramic window film (tinted or not). A1R's have better cab insulation as well and are quieter than older trucks. Honestly the only models worth looking for at this point - especially with prices having dropped or...

PTP is my go-to for turbo blankets: https://www.ptpturboblankets.com/collections/t3-t4/products/t3-t4-turbo-blanket-hybrid

Our turbo (3126/C7) is a Borg Warner S300 (made for CAT) and my spare M-ATV turbo (370 HP C7) is a T3 flange but based on that chart it's a 7 cm thick turbine housing so I guess a T4 blanket?

It likely won't take it all. You'll have to run it briefly to pump it through the cooler, and filters, etc before it will take the rest of the fluid.

Ah yes. 42nd week of 2016. Well you know the military was using it!

I think that's still a current menu item and near as I can tell it was introduced in 2014. There is likely a date code on the package. It was probably consumed within 1-2 years of production.

Then you have a significant chance of encountering more electrical problems as you continue to own the truck. The first thing every owner of these trucks should do is clean EVERY ground connection on the truck. Some, like the main cab ground strap, should just be replaced with one that is easier...

How many of the ~100 grounds have you cleaned so far? There's at least one or two behind each turn/park housing and some are nearby on marker lights, headlights, or inside the driver's side step with the washer bottle..... Also could be the flasher module or the column switch. Clean ALL...

Correct - the gauge runs off the MMDC on a closed loop CANBUS - they are entirely digital so just put that guy back in the dash. You will have to put a switch on the signal from the sending unit going into the MMDC (under the dash). While you are at it, add some inline filters to the front and...

I've used the Timesert kits. Used one on an aluminum Ford transfer case a lot of years ago. Worked without issue. The other option would be to get something like a Fumoto valve and epoxy it into the hole. Then you never actually have to remove it again. I use one of these for my engine oil...

The troubleshooting for that fault runs right to PDM 1 and when your reading is 0v at CB86's socket it tells you to replace PDM 1. 😅 I don't know about that. I think I would be checking for where PDM 1 is getting it's constant +12v from and where else it's sending it......

Maybe if you pull the gauge panel. Haven't looked at accessibility for that. Hopefully you can get to it. Otherwise it's going to be a lot of disassembly.

Yep. Worth testing but I'm guessing the constant +12v power supply to the PDM module for the accessory outlet is the issue. It is not ignition switched. The accessory outlet has power all the time unless you switch off the batteries.

Unlikely. There's no solder in the modular PDP panels. It's just riveted bussbars. I opened one:

Does anyone else think that railing would make a perfect push-bar for our trucks? :LOL:

The vast majority of operators don't know how to use the CTIS and definitely don't know what MODE does or how to manually shift down. Also they tend to not realize that it takes TIME for the CTIS to do it's thing so they push the button and immediately full send the truck to it's doom with no...

Supervising. Anytime you have more than three soldiers in a detail one of them transforms into a supervisor. This is even worse with civilian contractors. The effect seems to be exponential such that a sufficiently large detail has only chiefs and no braves.

Huh. Never seen one disabled on purpose. I doubt that story. The outlet is there to keep soldiers from running their own wiring to the batteries. I used to carry an inverter with alligator clips to run my portable DVD player off the HMMWV batteries. Fuses? We don't need that foolishness. And the...

If you want the most up to date electronic TM's send me a PM. The system has to have it's viewer software that is highly vertically integrated into the military maintenance support device (MSD). It's not just a manual - it's a maintenance system that integrates the manuals with the test hardware...
