4.
Check the condition of the wire-harness leads,
connectors, and terminals. Clean or repair them
as necessary.
5.
Verify that 12 V is present at the clutch connector
when the you engage the PTO switch.
6.
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 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
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
Troubleshooting (page
•
If the gap is sufficient, proceed to the
safety check in step F.
