Dear Half-Mast,
While servicing M920 tractor trucks, I’ve noticed a recurring problem.
The wooden spacer plate, NSN 5365-01-079-6540, that goes under
the batteries often rots and needs replacing. That part costs almost $50.
It sure would be nice to have this plate last longer in bad weather and
battery leakage. Do you have a tip that can help us?
SGT B.L.R.
Dear Sergeant B.L.R.,
Certainly. You still have to use the
spacer plate, but here’s a tip that should
help you out. Use battery box liner, NSN
The battery box liner should absorb
and neutralize battery acid and prevent
corrosion to the box. You’ll have to cut
enough liner to cover the entire bottom
of your truck’s battery box.
Then replace it
whenever you
need to.
Battery Spacer Plate’s Fate
hey buddy,
what’s up
with you?
T
he spare roadwheel hanging on the side of your M88-series recovery vehicle will
turn into a rusty ornament if you don’t keep it dry, mechanics.
When bolted to the side of
the vehicle, the roadwheel sits
at an angle. That allows rain and
wash water to pool in the bottom
of the roadwheel. The water sits
there until it evaporates.
When this happens over and
over, rust is the result. Not only
does the bottom of the roadwheel
develop severe rust, but the lug
nuts can actually rust in place
on the mounting bolts. Those
rusted bolts often snap when
you try to remove the nuts.
You can prevent the damage, but it’ll take a little work on your part. First, use
a little antiseize compound on the lug nuts and bolts when mounting the spare
roadwheel. That prevents rust and makes the nuts easier to remove later. Get a 4-oz
tube of antiseize compound with NSN 8030-00-059-2761.
Second, after washing your vehicle, and after any rainfall, take a few rags and soak
up the pool of water in the bottom of the roadwheel. That will keep the roadwheel
ready when you need it.

I hope they
remember to dry out

when it clears up…
…’cause I
hate rust!
