1.
Secure the Wear Plate in a vise.
2.
File the edge of the Wear Plate to take out any nicks and to
square rounded edges (Figure 39).
3.
Check with a Straightedge to ensure that the Wear Plate edge is
flat and straight.
Note:
If the Wear Plate is filed enough times that the proper gap between the
Knife and Wear Plate cannot be set with the Gap Gauge, you will need to replace
the Wear Plate.
Removing and Replacing the Wheels
The flywheel will still rotate for A WHILE after the engine is shut off. Shut down the engine, wait for all moving parts to come
to a complete stop, remove spark plug wire, then wait 5 minutes before moving or working on the chipper.
The Wheels on the MACKISSIC GRAVITY SELF FEEDING CHIPPER are pneumatic and have pressed in Bearings for easy
transport. With use,
tires or Bearings may need replacing. The following procedures will explain the replacement
procedures.
Tools and Parts Needed:
Large Flat Head Screwdriver
Cutting Pliers
Fine Tooth File
Soft Faced Hammer
Push Nut w/Cap

Pry the Cap off the axle with a Flat Head Screwdriver (Figure 40).
3.
Bend the Push Nut out with the Flat Head Screwdriver and cut it
with Cutting pliers so it can be pulled off the Axle.
4.
Remove the Pneumatic Wheel from the Axle.
Note:
There are spacers behind the wheel that must remain on the Axle
when the
Pneumatic Wheel is replaced.
Note: File off any marks in the Axle if Wheel will not slide on easily.
