Hydraulic System Cleaning Procedure After a
Hydraulic System or Transmission Overhaul
The hydraulic/hydrostatic system must be cleaned if
during repair the cause was from contamination and
the transmissions show wear on the pistons and
shoes, rotating piston blocks, valve plate or cam
plate.
IMPORTANT: Do not use the gear pump and charge
pump to flush the system with solvent. The solvent
will not provide enough lubrication to protect moving
parts inside the transmissions or gear pump.
1. Drain all remaining oil from the hydraulic system.
2. Remove fill cap, 1, and screen by removing the
six retaining screws, 2, from the reservoir fill.
Thoroughly clean the screen and fill breather cap
in solvent.

3. Drain and flush the hydraulic oil reservoir.

and belly pan.
CAUTION
Use a floor jack to support the belly pan to
prevent serious injury.
