A. Loosen both brake mounting bolts 1/2 to 1 full
turn as shown in
Figure 60 .
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 62 and Figure 63 .
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
(page ) .
•
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 blade-control switch (PTO)
is in the O
FF
position and the clutch is
disengaged.
Note:
If the clutch does not disengage,
install the shim, and refer to (page ) .
iii. Engage and disengage the blade-control
switch (PTO) 10 consecutive times to
ensure that the clutch is functioning
properly.
Note:
If the clutch does not engage
properly, refer to (page ) .
