The power divider style rear axle was used either in late 2006 or 2007. The cab air shocks were removed for the A1R, so late 2004 and onward.

The armored A1P2 has a lift system that is entirely different from the previous unarmored versions.

The greasy stuff is paraffin based rustproofing wax. And yes it will interfere with welding. It will catch fire easily also.

All surplus armor is to be scrapped. The government sold 3 million pounds of new LSAC cabs a few years back and all were scrapped. One can buy a cab from Oshkosh for $25K but you will likely need another $100K in parts to get it to work, as there are substantial differences in the truck between...

Here is a list of things that you will have to service eventually: Hydraulic pump Cab latch Fuel lines Cab mounts The obvious stuff, filters fluids etc. CTIS system will likely need addressing, axle seal failures are common, as are the control block.

Fuel is pulled from the tank by the pump/governor assembly. The 3116 doesn't have a typical injection pump, each injector is it's own pump.

I recall reading about 3116 injector sleeve problems, and they can be fixed by replacing the sleeves.

Red River parts had them, and knows how to ship them. Be fore warned, shipping will cost as much as the windshield.

They were rustproofed but not very well. There was also an option for the earlier trucks to have additional rust proofing. One problem was the undercoating was water soluble.

LMTV factory A/C is approx 30,000 btu. The heavy equipment air conditioners are typically designed to cool a volume not much larger than a person. There are also power supply issues with the LMTV alternator, a 100 amp alternator is far undersized to power a 7K btu cooling unit let alone a 30K...

McMaster Carr has something similar to that. Not sure if it's the same though.

Also the engines got quieter and smoother and more powerful over the years. The 3116 sounds like a clothes dryer full of rocks compared to a C7.

rebman333 I've got 4 LMTV's with C7's for sale.

Check the fuel lines, age causes them to crack and suck air.

Check the engine/trans mounts, I've bought a few rollovers and all had busted brackets, busted rubber mounts, and the frames that hold the trans/engine were twisted.

There are several slight variations of bumper, some had side marker lights, some had the towing electrical cable plug placed in different locations. For the most part the A0 and 3126 A1's had the same bumper. The A1R had a different bumper along with a different front skid plate. Not sure on...

I've got the newer tech manuals. And yes the 3126 had a better warning light system but still had the 3116 gauges. The C7 got an entirely updated gauge panel. Regarding electrials The 3116 had the realy/circuit breakers. The 3126 had the huge circuit panel that sucks. The C7 got the Power...

For the most part the trucks are all the same. Here are some notable changes 1993 to 1998 was the 3116 engine. 1999 to mid 2004 had the 3126 later 2004 to present had the C7 1998 to 2005 had the WTECIII trans controller Late 2005 had Gen IV trans controller and 3500SP transmission 2006+ saw the...

Not all A1's have the battery disconnect solenoids. That appears to be a running change in the 2003 model year. Older A1's have the same battery wiring as the A0.

It's a C7.
