A
tank loader’s seat adjuster is good
for only one thing—to adjust the
loader’s seat.
It may look like a good step when
getting in or out of your tank, but guess
what?
Your weight will strip and break
the seat adjuster’s pin, NSN 5315-01-
285-4536.
So use the seat adjuster for its intend-
ed purpose and keep your big feet off!

M1-Series Tanks…

hecking your tank’s engine exhaust seal is a
monthly check, crewmen. But what you do after
the check can make or break the seal.
After closing the exhaust grille doors, you need
to secure them in place with two bolts and J-hooks.
The bolts are supposed to be torqued to 295-350 lb-
ft. Since crewmen don’t have a torque wrench, a
mechanic should do the job.
Unfortunately, some crewmen tighten the bolts
anyhow. When the bolts come loose, the grille
doors bounce up and down and tear the seal. Then
you have to call in a mechanic to replace it.
So do the job right the first
time and ask your mechanic
to torque those bolts.
Mechanics, before you do,
make sure you coat the bolt
threads with antiseize com-
pound, NSN 8030-00-597-
5367. That makes the bolts
easier to remove next time.
Also, you may notice a little
gouging on the surface of the J-
hooks as you torque down the bolts.
The J-hooks are made from a lower-
grade steel, so gouging is common.
Don’t let it stop you from tighten-
ing the bolts to the proper torque,
though. Replacing a J-hook is a lot
cheaper than buying a new grille
door or exhaust seal.
