Using the Clutch Shim
Some later model year units have been built with
clutches that contain a brake shim. When the clutch
brake has worn to the point where the clutch no longer
engages consistently, the shim can be removed to
extend the clutch life.

Removing the Clutch Shim
1.
Shut off the engine, wait for all moving parts to
stop, remove the key, engage the parking brake,
and allow the machine to cool completely before
starting these instructions.
2.
Using an air compressor, blow out any debris
from under the brake pole and around the brake
spacers
(Figure

3.
Check the condition of the wire-harness leads,
connectors, and terminals.
Note:
Clean or repair as necessary.
4.
Verify that 12V is present at the clutch connector
when the blade-control switch (PTO) switch is
engaged.
5.
Measure the gap between the rotor and
armature. If the gap is greater than 1 mm (0.04
inch), proceed with the following steps:
A.
Loosen both brake-mounting bolts 1/2 to 1
full turn as shown in
Note:
the field shell/armature. The brake pole has
worn to match the armature and needs to
continue to match after the shim is removed
to ensure proper brake torque.
