4. Verify that 12V is present at the clutch connector
when the blade-control switch (PTO) switch is
engaged.
5. 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, hold
the tab and remove the shim
Note:
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. Torque each bolt (M6 x 1) to 13 N∙m (10
ft-lb) +/-0.7 N∙m (0.5 ft-lb).
E. Using a 0.25 mm (0.01 inch) thick feeler
gauge, verify that a gap is present between

the rotor and the armature face on both
sides of the brake pole as shown in
76 and Figure
Note:
Due to the way the rotor and the
armature faces wear (peaks and valleys) it
is sometimes difficult to measure the gap
accurately.

If the gap is less than 0.25 mm (0.01
inch), then install the shim; refer to
Troubleshooting (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 with the blade-control switch
(PTO) in the O
the clutch is disengaged.
If the clutch does not disengage,
install the shim again; refer to
Troubleshooting (page
iii. Engage and disengage the
blade-control switch (PTO) 10
consecutive times to ensure that the
clutch is functioning properly.
