Wandering Neurons. Arrived and set up home just east of Colorado Springs a couple of months ago. Had my M1081 LMTV transported out, and drove out my kit truck, clone of HMMWV, after 4th of July. I see there’s a few other Colorado Springs residents on various forums here. Lots of stuff to do!

So my M1081 from Ft. Bragg has the dovetail plate and an antenna wire sticking out, on the passenger side behind the door. Was wondering what this was for and if I could use it for anything. Though I pulled the passenger side radio rack out, it was empty, and put another storage bin in its...

Talk to Joey Magee at United States of Freight - 561-617-0120. He arranged shipping for my M1081 from Southern Maryland to Colorado Springs for a good price, and it was done quicker than expected.

Understood, neither my Zombie Truck nor my M1081 have OBD. I bought a plug that allows me to feed the OBD plug that services the HUD. So I go from +12v to the OBD cable that feeds the HUD. Not elegant but works. And keeps my phone off the dash.

I've used several of the cheap heads-up displays from the "big-A" site. My Zombie Emergency Response Vehicle (kit HUMMER) has a goofy speedometer, so the HUD is the replacement. The HUDs rely on GPS for speed and time, and you'll need a VIN plug to power the HUD. My HUD has a mini-USB cord that...

Ok, that makes sense. The picture looked funny, thought it had been a 6x6 minus the rear axle initially. Matt really had to do something different and makes sense based on the owner’s need and your parts availability. In the interest of expenses and trouble, I’ll pull my drive shafts and have...

But is it truly worth the trouble? If it’s not a simple bolt-in I’m outa luck. I use a torch to turn metal pieces into expensive scrap.

I grok the definition between LMTV and FMTV. Was just thinking about drive shaft angles. Didn’t realize that the 6x6 used different mount points for the axles. Oh well, another theory shot.

Ok, stupid question: why can’t a FMTV intermediate axle be used as a rear axle in a 2-axle LMTV to reduce the drive shaft angle, assuming that air pressure is used to engage the power divider all the time? Is there some fitment that wouldn’t work?

Even a 10% increase in effort still puts it well below what an M35 driver has to deal with. The original definition or “Armstrong Steering”. I remember well the agony of driving my old truck. The LMTV is so much better.

D1 is the fault code position. 21 is the main code, 12 the subcode. According to this (http://ww2.justanswer.com/uploads/HE/HeavyEquipmentTech/2013-09-22_223029_allison_transmission_md3060_trouble-shooting.pdf) for WTEC II (same code for III), you've got a Throttle Position Sensor failed or out...

If my experiences with my RV's Allison transmission are similar enough to yours, you might have a sensor-related problem. There's three sensors feeding input into the TCU. If any one of them go wonky, the TCU will "lock" the trans into the lowest normal gear so you can move, but that's all it'll...

What changed between Start #1 and Start #2? Batteries? Sounds like you've got more than one with bad cell or shorted internally?

Update: Searching for "3116 aneroid governor" I found a decent writeup on turning up the fuel on the Caterpillar 3116: https://www.justanswer.com/heavy-equipment/1xedq-3116-cat-engine-dump-truck-turn-power.html There's three things to do: 1. Block the aneroid line that feeds air pressure into...

aneroid makes sense. Pressure sensing valve. Thanks much!

Thanks for the info, something to add to potential mods on my truck!

Well, the brass valve on the PCU has been checked and swapped, so I just ordered a set of filters, though the order may take a few days. I'm going to double-check the wheel valves, I may have tested them while the CTIS was pressuring the tires. But that's an easy test... Thanks for the info...

OK, not 100% operational as hoped. From HWY, if I select XC or SAND, get about 30-40 seconds of pressure coming heavily from both QRVs underneath (verified by crawling underneath and checking both). After the 30-40 seconds, HWY and XC lights come on steady. Press XC or SAND again, another 30-40...

I think that the ECU, when it first powers up looks at the pressure transducer even before there's air pressure. That's why my ECU was throwing a fault whether I was using the engine compressor or shop air to supply air. With the engine compressor, it'd take a minute or two for pressure to come...

PM me. I've got my old parts
