MAINTENANCE
CUTTERHEAD BEARING YEARLY SERVICE
(if machine built pre 4/20)
DANGER
!
Before attempting any type of maintenance, disengage clutch, wait for the cutterhead to come to a complete
stop, turn off engine, remove the ignition key, make sure the ignition key is in your possession, wait 2 minutes
and then disconnect the battery.
1. Follow all pre-maintenance shut down procedures.
2.
Clean off and around bearing.
3. Mark the bearing cap and bottom of the bearing housing to make sure the bearing cap is installed
correctly after greasing the bearing.
4. Release belt tension before removing the 2 cap bolts and 2 bolts that pass through the entire housing
and mounting pad from the bearing housing.
5. With a pry bar, pry sequentially under the cap pry slots at each corner of the bearing.
6.
Lift off the bearing cap, inspect, and wipe off the interior.
7. With nitrile gloves on and a clean rag, manually scoop and wipe out the grease from the bearing cavity
and place in a disposal bucket. See Figure 1.
8.
Manually work new grease into existing bearing while slowly turning the bearing and remove the old
grease as it gets pushed out by the new grease. See Figure 2.
9.
Fill the bottom bearing housing to approximately 1/2 full and apply some grease to the bearing cap.
See Figures 3 through 5.
10. Ensure mating surfaces are clean and labyrinth seals are seated properly. Match marks have to line up.
11. Reinstall the bearing cap and tap with a rubber hammer until the top and bottom halves of the bearing
housing are seated.
12. Clean the bearing housing cap bolts and lightly oil.
13. Reinstall the four bearing housing cap bolts and retorque sequentially (a clockwise pattern is suggested
in 5 ft-lbs (7 Nm) increments are suggested). The 2 cap bolts that go into the bearing housing are torqued
to 375 ft-lbs (508 Nm) and the 2 cap bolts that go through bearing housing are torqued to 40 - 45 ft-lbs
(55 - 67 Nm) cutterhead bearings. See Figure 6.
