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
Figure 59 .
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 the proper brake torque.

B. Using needle-nose pliers, or by hand,
remove the shim.
Note:
Do not discard the shim until you
confirm that the clutch functions properly.

C. Using a pneumatic line, blow out any debris
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
Figure 61 and Figure 62 .
Note:
Due to the way the rotor and
armature faces wear (peaks and valleys), it
is sometimes difficult to measure the true
gap.

•
If the gap is less than 0.010 inch,
then install the shim and refer to
Troubleshooting (page 56) .
•
If the gap is sufficient, proceed to the
safety check in step
F .
F. Perform the following safety check:
i. Sit on the seat and start the engine.
ii. Make sure that the blades do not
engage when the PTO switch is in
the O
FF
position and the clutch is
disengaged.
Note:
If the clutch does not
disengage, install the shim, and refer
to
Troubleshooting (page 56) .
iii. Engage and disengage the PTO
switch 10 consecutive times to
ensure that the clutch is functioning
properly.
Note:
If the clutch does not engage
properly, refer to Troubleshooting
(page 56) .
