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.
5.8 clearinG a pluGGeD roTor
1. Shut off engine and allow all moving parts to come to
a complete stop.
2. remove the retaining bolts holding the access cover to
the main frame assembly and lift up access cover.
3. Clean the debris out of the chipping rotor. Turn the rotor
by hand to be sure it is free to rotate.
5.9 luBricaTion
Figure. 5.9, Grease zerk locations
lubricate the machine periodically with a lithium-based
grease. Extreme working conditions will require more
frequent greasing.
grease the following points every 50 hours of operating
time:
• Two bearings on the rotor shaft.
• One grease zerk on the discharge chute.
• One grease zerk on belt engagement lever.
9. Slide the bushing and sheave off the rotor shaft.
10. Remove the two 1/2" bolts on each rotor bearing and
remove the roll pin from the rotor shaft.
11. using an overhead hoist or lifting device, lift the rotor
assembly completely out of the frame. The complete
rotor assembly is 140 lbs.
12. Once the rotor assembly is out of the frame, remove
both bearings and place new bearings on shaft.
13. replace roll pin.
14. use the overhead hoist or lifting device to return the
complete rotor assembly to the chipper frame.
15. Install the 1/2" bolts on engine side bearing and tighten.
Install the nuts onto the other bearing and tighten. slide
rotor over to the engine side until the roll pin is tight
against the bearing. lock the set screws and torque to
160 inch-lbs. Torque bearing bolts to 75 ft-lbs. Check
and adjust chipper anvil to 1/16” clearance if needed.
16. Install the spacer on the shaft.
17. Slide the sheave onto the shaft and then install the
bushing and slide it all the way up to the spacer. Align
drilled holes in the bushing flange with the tapped
(threaded) holes in the sheave. Install the capscrews
through the bushing holes and into the tapped holes
in the sheave. Tighten the capscrews evenly and
progressively in rotation. Torque to 180 inch-lbs.
18. Recheck pulley alignment. Pulley faces should line up.
If not, readjust and repeat alignment check.
19. Replace drive belts on pulleys, install the idler
assembly, slide engine back into place, and retighten
bolts. Check alignment of pulleys and belt tension.
Adjust if needed.
20. Move the engagement lever to the CHIPPINg position
and install the belt guides so you have an 1/8" of
clearance.
21. reinstall belt guard.
22. Move the engagement pedal back to the START
position, start engine, engage drive belt slowly, and
test unit. Readjust pulleys if needed.
4. Close rotor access cover and replace bolts.
5. start engine and engage drive belt to resume
operation.
noTe
Do not over grease bearings. Overfilling can lead to
excessive heat and/or unseating of the seals. Add
grease slowly and under light pressure. Whenever
possible, rotate bearing slowly while lubricating.
imporTanT
Polyurea and lithium-based greases are not compatible.
Mixing the two grease types may lead to premature failure.
