it’s this
throttle
lever
--
it won’t
budge!
what’s
wrong?!
the linkage for the
governor control
lever (throttle)
gets corroded
from moisture.
over time,
enough corrosion
or rust makes
the lever Hard to
push or pull… if
it moves at all.
a stuck
lever isn’t
much good
when you
need to
increase or
decrease
engine
speed
during
operations.
positioning the grader blade is a
“sticky” business when the vehicle
sits too long without exercise.
no exercise means the
grader’s centershift
pin rusts in place.
then you can’t move
the pin in and out of
the centershift hole to
position the blade.
your grader’s sloping
operations just came
to a screeching halt!
here are
two
things
you can do to help get
the centershift pin out.
by the way, WP 0039 and
WP 0041 of tm 5-3805-
261-10 have the lowdown
on the centershift pin.

Lube Helps “Sticky” Pin
Paint Shop Reminder
Before your dozer heads off to the paint shop, tape over the throttle linkage where it
connects into the mounting bracket. That way the linkage won’t get stuck “in place.”
Just make sure the tape is removed when the dozer comes back from the paint shop.
To
prevent
these
problems, wipe off the
throttle linkage with a
brush or clean rag. Then
spray pivot points and
connections with a shot
of
lubricating
spray,
Move the throttle lever
back and forth a few
times to work it in.
Make sure to spray the linkage at
every scheduled service. Lube puts the
slide and glide back into the linkage for
smooth operation of the throttle.
