5.
Verify that 12 V is present at the clutch connector
when the blade-control switch (PTO) switch is
engaged.
6.
Measure the gap between the rotor and
armature. If the gap is greater than 1 mm (0.04
inch), do 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 you remove the
shim 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 the
clutch is functioning properly.

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 12.3 to 13.7
N∙m (9.5 to 10.5 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

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.
•
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.
iii.
Engage and disengage the
blade-control switch (PTO) 10
consecutive times to ensure that the
clutch is functioning properly.
