E
xperience is never a substitute for the education you get from your
vehicle’s TM. Sadly, a seasoned mechanic found that out the hard
way. While replacing the cab hydraulic cylinder on an M1078 LMTV,
the 3,000-lb cab dropped on him. He didn’t survive.
Mechanics, make sure you follow the guidance in the TM
every
time
you work on vehicles. You’ll Fnd the procedure for replacing
the cab hydraulic cylinder in your ±MTV’s maintenance TMs. They
call for the use of a cab support tool that keeps the cab from falling.
Your unit can order the cab support tool using NSN 2590-01-559-
7459. It can be used on ±MTV -A0, -A1, and -A1R trucks and is
included with the ±MTV Feld-level maintenance special tools kit,
NSN 5180-01-545-9967. There’s no requirement for a cab support
tool to be used on ±MTV -A1P2 LTAS trucks.
Or the life-saving cab support tool can be made using ²at bar steel,
a piece of angle iron, and Insulgrip (PN H.S. 105VW-1). You can use
the fabrication details that start on Page E-6 of TM 9-2320-365-20-4.
Keep in mind that if your unit doesn’t have a cab support tool,
you shouldn’t be doing maintenance that requires it. Make sure you
use either a cab support tool or a suitable lifting device to protect
yourself.
On the work order, show the truck in a “P” status until the tool
is available. That means it’s NMC for lack of facility, tools, test
equipment or completion of intra-shop work requests.
