Snug Filler Plug
Operation at the worksite causes vehicle
vibration. Vibration loosens the plug in the
transmission’s oil fller tube. Once loosened,
the plug can Fall oFF. A missing plug means
that sand, dust and water can get into the
dozer’s transmission.
So beFore the day’s run, make sure the
plug is snug. Never stuFF a rag or anything
else in the fller tube iF the plug is missing.
Instead, have your mechanic replace the plug
with NSN 4730-01-249-8409. It’s shown as
Item 7 in ±ig 82 oF TM 5-2410-237-24P.

Breather Valve Reminder
A plugged breather valve will KO the dozer’s transmission. It usually gets
overlooked because oF its location under the operator’s seat. Two things happen
when the valve gets clogged:
•
Pressure builds in the transmission and causes seals to blow. When the seals go,
lube goes, too. No lube means added Friction and gear damage.
•
Pressure build-up also creates a vacuum in the transmission. That causes the
transmission to stall or lock up. Then you can’t move!
So keep the breather valve
clean. It’s simple to do. Just tap
on the valve with your fnger
to loosen any dirt stuck inside.
IF the valve won’t go down
or come back up, have your
mechanic replace the valve,
NSN 2520-01-164-0077. It’s
shown as Item 9 in ±ig 83 oF
TM 5-2410-237-24P.
