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.
The fan housing wear liners are replaceable. To replace
the wear liners:
1. Shut o󰀨 engine and allow fan to completely stop.
2. Remove the fan intake weldment from the fan housing.
3. Remove the 7/16" × 1-1/2" bolt and washer from the
end of the engine crank shaft.
4. Remove Cat Claws™ (SN: J03492 and above),
bushing and fan from the engine crank shaft.
5. From the outside of the vacuum shredder housing,
remove twelve 5/16" nylock nuts that hold the three
wear liners.
6. Remove the old wear liners and insert the new liners.
7. Install the new wear liners with twelve 5/16" × 3/4"
carriage bolts and nylock nuts. Feed the carriage
bolts from inside the vacuum shredder housing.

9. Reinstall the 7/16" × 1-1/2" bolt and washer to the
engine crank shaft. Torque to 50 ft-lbs.
10. Make sure approximately 1/4" clearance exists
between the fan housing and the fan plate.
5.4 REPLACING THE WEAR LINER
The vacuum shredder is designed to be used in fairly dry
conditions. Wet material, along with too much debris and
large sticks, can plug the fan or hose. A plugged fan bogs
down the engine and can possibly stop the engine if the
fan is severely plugged. To clear the fan:
1. Shut o󰀨 engine and allow fan to completely stop.
2. Remove spark plug wire.
3. Loosen the six 5/16" nuts that hold the intake
weldment to the vacuum shredder frame.
4. Turn the vacuum intake counterclockwise to remove
it.
5. Check the hose for clogs and clear debris from the
fan.
6. Turn the fan by hand to verify it is unplugged.
7. Place the intake weldment over the six frame nuts
and turn it clockwise to set the studs in the weldment
notches. Tighten 5/16" nuts to 17 ft-lbs.
8. Reconnect spark plug wire and resume operation.
5.5 CLEARING A PLUGGED FAN
1. If the hose becomes plugged during operation,
straightening the hose may dislodge the clog.
2. If straightening the hose does not work, shake the
hose in an up and down or side to side motion.
3. If the clog remains after performing the above two
steps, shut the engine o󰀨 and wait for all moving parts
to stop moving. Then, remove the hose from the fan
housing and manually unplug the hose.
