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 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.

B. Using needle nose pliers, or by hand, take hold
of the tab and remove the shim (Do Not discard
the shim until proper clutch function has been
confirmed).

C. Using a pneumatic line, blow out any debris
from under the brake pole and around the brake
spacers.
D. Re-torque each bolt (M6 x 1) to 10 ft-lb (13 N-m)
+/-0.5 ft-lb (0.7 N-m).
E. Using a 0.010 inch thick feeler gauge, verify that
a gap is present between the rotor and armature
face on both sides of the brake pole as shown.
(Due to the way the rotor and armature faces
wear (peaks and valleys) it is sometimes difficult
to measure the true gap.)
