4. Tighten the locknut until the spring washers are flat
and then back off a 1/4 turn to properly set the
pre-load on the bearings (Figure 64).
Important:
Make sure the spring washers are
installed correctly as shown in Figure 64.
5. Install the dust cap (Figure 64).

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. Stop the engine, wait for all moving parts to stop,
and remove the key. Engage the parking brake.
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 66
3. Check the condition of the wire harness leads,
connectors, and terminals. Clean or repair as
necessary.
4. Verify that 12V is present at the clutch connector
when the PTO switch is engaged.
5. Measure the gap between the rotor and armature.
If the gap is greater than .04 inch (1 mm), 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 the shim is removed to ensure proper
brake torque.
