I figured I would start a thread to do with military convoy trucks cause they don't seem to be getting much love...HEMTT, HET, 915, 916, 920...Anything running the roads here in Iraq...
80% of my work here in Iraq is M1070 HET trucks (we have done over 30 since we took over on October 1), MAC time on an engine or tranny swap says it takes 13 hours just to pull the cab with 4 men, we have got it down to 1.5-2 hours with 3 or 4 men using mostly hand tools...We can pull the engine/tranny pack just after lunch and have the tranny ready to slide into the new engine before the end of a 12 hour shift normally (day 1), after installing the tranny you got to reinstall your hydro and air pumps (PITA) along with all your ancillary stuff (front pulley, alternator mounts, A/C compressor) and drop your pack back into the truck and hook everything back up and be ready for the cab by late afternoon, drop the cab, and start hooking everything up and have it almost ready to fire by the end of the day, (day 2) we double check all the fluids, test fire, troubleshoot if there is a no start (normally it wont start), fire and run it some, check fluids, bolt it together enough to do a test drive around the yard, bring it back and check for leaks, no leaks (yeah right
) we recheck all the fluids and fill them up, put everything back on but the BII box and the spare tire and send the beast to QA/QC for inspection, after it passes we bolt the last 2 pieces of the puzzle together and put her on the ready line for pick up (day 3)...
For those of you that dont know what M1070 HET is, here is what one looks like...They are powered by a 500 HP 8V92TA 2 Stroke Detroit (700 HP C16 Cat in Europe for emissions) backed by a 5 speed Allison Automatic, 6/8 wheel drive (selectable), front and rear axles steer, the M1000 HET Trailer has 40 tires, each set of axles turns opposite of the trucks direction (it can turn around in spots smaller than some crew cab pickups with gooseneck campers) and the deck has 3 hydraulic controls so you can drop the curb side or street side angle of the deck for weight distribution and also drop the back half of the deck almost on the ground for easier loading, has about 30 inches of useable suspension travel on the trailer...Empty in full battle rattle it weighs just shy of 100K, fully loaded with an M88 Recovery Unit it weighs a svelt 280K pounds...Top speed is 48 MPH...
