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, you can remove the shim to
extend the clutch life.

4.
Check the condition of the wire-harness leads,
connectors, and terminals.
Note:
Clean or repair as necessary.
5.
Verify that 12 V is present at the clutch connector
when the blade-control switch (PTO) switch is
engaged.
6.
Measure the gap between the rotor and
armature. If the gap is greater than 1 mm (0.04
inch), do 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 you remove the
shim to ensure proper brake torque.
