130G Grader…
Oil Level
Make sure the grader is on
level ground before you do the
tandem oil check shown on Page
2-27 of TM 5-3805-261-10. That
way you get an accurate reading.
Keep the level between the ADD
and FULL marks on the dipstick.
Too much oil in the tandem is
just plain wasteful. Not enough
oil means the drive wheel com-
ponents inside the tandem don’t
get lubricated.
Dipstick Vent Hole
Once you’ve checked the
oil level in the tandem, make
sure the vent hole in the dip-
stick cap is clear. When it’s
clean, the cap acts as a
breather valve for the tandem.
Use a paper clip to clean any
crud out of the vent hole.
Air Line Bind
Eyeball the air line that’s mounted along the grad-
er’s tandems. This air line is part of the vehicle’s air
brake system.
Look for dents and holes in the air line caused by
rocks and gravel. During construction operations,
rocks and gravel pile up on the tandem. A large rock
thrown on the tandem will dent the air line. Enough of
a dent or hole means loss of air pressure for the grad-
er’s air brake system and loss of brakes at the worksite!
So look real
close for any
dents or holes
in the air line.
It could mean
the difference
between get-
ting the job
done and no
brakes at all.
They’re in
tandem with your
grader’s mission
requirements.

Hey, big
guy, you
ready for
the day?
Not until you
run through
some tandem
checks.
Keep these
PM tidbits in
mind
before
the day’s run.
