2. Engage the parking brake and wait for the
machine to cool completely.
3. Using an air compressor, blow out any debris
from under the brake pole and around the brake
spacers.

4. Check the condition of the wire-harness leads,
connectors, and terminals. Clean or repair them
as necessary.
5. Verify that 12 V is present at the clutch connector
when you engage the blade-control switch
(PTO).
6. 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:
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,
remove the shim.
Note:
Do not discard the shim until you
confirm the proper clutch function.

C. Using a pneumatic line, blow out any debris
from under the brake pole and around the
brake spacers.
D. Torque each bolt (M6 x 1) to 12.3 to 13.7
N∙m (9.5 to 10.5 ft-lb).
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 in
Note:
Due to the way the rotor and
armature faces wear (peaks and valleys), it
is sometimes difficult to measure the true
gap.
