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

Removing the Clutch Shim
1.
Park the machine on a level surface, engage the
parking brake. shut off the engine, wait for all
moving parts to stop, and remove the key. 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.

3.
Check the condition of the wire harness leads,
connectors, and terminals. Clean or repair as
necessary.
4.
Verify that 12 V is present at the clutch connector
when the PTO switch is engaged.
5.
Measure the gap between the rotor and the
armature. If the gap is greater than 1 mm (0.04
inch), proceed with the following steps:
A.
Loosen both brake mounting bolts one-half
to one-full turn as shown below.
Note:
Do not remove the brake pole from
the field shell/armature. The brake pole
has worn to match the armature and needs
to continue to match after you remove the
shim to ensure proper brake torque.
