SERVICE & MAINTENANCE

WARNING

BEFORE INSPECTING OR SERVICING ANY PART OF THIS MACHINE, SHUT OFF POWER SOURCE, 

AND MAKE SURE ALL MOVING PARTS HAVE COME TO A COMPLETE STOP.

1.  Remove the discharge door, discharge screen, belt 

guards and rotor shaft end cap.

2.  Loosen the bushing bolts holding the drive pulley to 

the shaft and remove the pulley.

3.  Loosen the set screw in the lock collars. Using a 

punch and hammer, tap the lock collars in the opposite 

direction of normal rotation. Remove the lock collars.

4.  Loosen the set screw in the center of the rotor 

assembly.

5. 

Remove the two 3/8" × 1/2" bolts running through the 

rotor shaft.

6.  Using a rubber mallet or other soft hammer, drive the 

shaft towards the chipper chute side of the machine.

7.  Once the shaft has been removed, the rotor assembly 

can be removed through the discharge opening.

8.  To ease reinstallation, smooth any divots or marks in 

the shaft caused by the set screws. Clean the shaft as 

much as possible before reinstalling into the machine.

5.12 REMOVING THE ROTOR

The rotor weighs in excess of 100 lbs. It is extremely 

important to support the rotor to prevent it from falling 

or shifting as the shaft is removed.

WARNING

5.13 PTO DRIVELINE LUBRICATION

1. 

Every  8  hours,  lubricate  PTO  cross  journals.  Make 

sure grease purges through all four bearings. 

2.  Every 8 hours, lubricate PTO inner tubes. Telescoping 

members must have lubrication to operate 

successfully.  Telescoping  members  without  fittings 

should be pulled apart and grease should be added 

manually with a brush. 

3.  Every 8 hours, lubricate the PTO shield retaining 

bearing. Molded nipples on the guard near each 

guard  bearing  are  intended  as  grease  fittings  and 

should be lubricated every 8 hours of operation.

To  prevent  personal  injury  or  property  damage: 

Disconnect the PTO driveline from the source providing 

power or disconnect the driveline from the chipper 

and make sure that all moving parts have come to a 

complete stop, before servicing, adjusting or repairing.
