f you can’t remember the last time you serviced the FMTV’s air dryer, it’s probably
been way too long, mechanics.
If the paint hasn’t
been disturbed on the
line fittings and canis-
ter hardware, chances
are the air dryer isn’t
doing much drying
anymore. That means
water is in the air lines
and tanks. Rust—and
ice in winter—won’t
be far behind.
A
loose starter on your HMMWV is the start of a big problem. Eventually it’s
going to end up on the ground.
It’s tough to tell if the starter’s loose just by looking at it, though. Loose bolts may
look tight. And it’s hard to tell with a visual inspection if the mounting bracket’s
cracked.
Your best bet is to crawl under
the vehicle and push up on the
starter. If it moves, call in your
mechanic to fix the problem.
FMTV…
You’ll be referred to Para
23-6 in the -365-20-5 TM or
Para 23-11 in the -366-20-5
for servicing instructions.
The IETMs provide a service
button that takes you to the
servicing instructions. Those
sections tell you how to
remove and replace the desic-
cant cartridge and check the
heating element that removes
moisture from the air before
it goes to the primary and
secondary air tanks.
