IMPORTANT: If couplers were not disconnected prior to removing the control valve, oil
will drain from the skid steer causing extensive oil loss.
3. Remove the capscrews holding the motor to the drive bearing housing, and remove the
motor. Check motor seal for damage and replace if required.
NOTE: If motor shaft seal was damaged you will need to drain the existing oil from the
drive bearing housing and replace with new before installing the new motor. See in-
structions for Changing Oil in Drive Bearing Housing.
4. Grease the new motor spline shaft and install the new motor with o’ring onto the drive
bearing housing using the existing hardware. Torque to specifications. See Bolt Torque
Specifications.

hardware. Be sure o’rings are properly positioned when installing valve. Torque cap -
screws to specification. See Bolt Torque Specifications.

Torque Specifications.
REPLACING DRIVE BEARING HOUSING
(GS SERIES CUTTERS ONLY - 30-45 GPM)
When replacing the drive bearing housing, the unit must be detached from the prime
mover in a clean, open location with a hoist available that has adequate lift capacity for lifting
the attachment. Be sure all rotation has stopped before making any adjustments or re-
pairs.
1. With the unit disconnected from the prime mover and the front shield removed, attach
a hoist to the two front lift locations on the push bar and slowly lift the brush cutter and
place it upside down with the blade carrier wheel exposed.
NOTE: Be prepared for possible shifting of the brush cutter as it is clears the ground.
Block the cutter, if required, to ensure it is completely stable before proceeding.
2. Remove the eight capscrews securing the drive bearing housing to the blade carrier.
