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
Figure
70 and Figure 71 .
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 76) .
•
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
FF
position, and that
the clutch is disengaged.
If the clutch does not disengage,
install the shim again; refer to
Troubleshooting (page 76) .
iii. Engage and disengage the
blade-control switch (PTO) 10
consecutive times to ensure that the
clutch is functioning properly.
