Driveshaft Lube
Three grease fittings on the hydraulic pump’s driveshaft are overlooked during
scheduled services.
Without lube, the U-joints on the pump’s driveshaft shake loose from vibration and
excessive wear. Also, the shaft’s bearings rust and burn out.
Eventually, the driveshaft and
pump stop working. Then no
hydraulic fluid gets pumped to
the grader’s blade, circle drive,
scarifier or front wheel tilt. Their
components shut down and your
grader is NMC.
So keep the pump’s driveshaft lubed. During scheduled services every month, give
each of the fittings four or five pumps of grease.
Centershift Pin
The centershift guide pin rusts in place
when the grader sits too long without exercise.
When that happens, you can’t move the pin
in and out of the centershift hole to position the
grader’s blade. That means your grader’s slop-
ing operations just came to a screeching halt!
It just can’t be said often enough—exercise
your grader! Operate the centershift pin from
its hole
at least once a week.
That way rust
won’t “freeze” the pin in place.
Pages 2-8 and 2-9 of TM 5-3805-261-10 have the lowdown on the centershift pin.
