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.
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 and refer to
Troubleshooting (page 64).
•
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 the blades do not engage with
the PTO switch in the Off position, and
that the clutch is disengaged.
If the clutch does not disengage, install the
shim again and refer to Troubleshooting
(page 64).
iii. Engage and disengage the PTO switch 10
consecutive times to ensure that the clutch
is functioning properly.
