CHANGING OIL IN DRIVE BEARING HOUSING
When changing the oil in the drive bearing housing the unit should be setting firmly on
the ground with the hydraulic couplers disconnected. We recommend removing the existing oil
with a fluid removal pump.
1. Remove one of the plugs in the drive bearing housing and place the extraction hose into
the housing so that it reaches the bottom.
2. Place the output hose into an approved container or drum that will hold the waste oil.
3. Following the instructions for your fluid removal pump, remove all oil from the drive
bearing housing. Once the oil has been drained from the housing, remove the pump.
4. GSE Series (20-34 GPM) Cutters: Fill the housing up to the plug with a mild extreme
pressure lubricant API-GL-5, No. 80 or 90 weight gear lubricant.
GS Series (30-45 GPM) Cutters: Fill the housing with approximately 2.50 quarts (2.4 li -
ters) of a mild extreme pressure lubricant API-GL-5, No. 80 or 90 weight gear lubricant.
NOTE: Oil level should be approximately 2” (51mm) from the top when measuring
down from the plug.
5. Replace plug. Torque to specification. See Bolt Torque Specifications
