Procedure:
With engine off, key removed and clutch disengaged and
using a pneumatic line, blow out any debris from under the
brake pole and around the aluminum spacers. Figure 4-28
Check the air gap between rotor & armature with feeler
gage. If the gap is less than .070”, then follow the
troubleshooting procedure outlined in Warner Electric P1177
installation troubleshooting guide available on Warner
Electric’s web site, www.warnerelectric.com. If the air gap is
over .070”, follow the procedure outlined below. Figure 4-29
1. Loosen both brake mounting bolts 1/2 to 1 full turn as
shown in Figure 4-30.
2. Using needle nose pliers, or by hand, take hold of the
tab and remove shim (do not discard shim until proper
clutch function has been confirmed). Figure 4-31
3. Using a pneumatic line, blow out any debris from
under the brake pole and around the aluminum
spacers. Figure 4-28
4. Re-torque each bolt (M6 X 1) to 120 in.-lbs (13.5 N•m).
A. Brake fastener
B. Brake spacer
C. Field shell
D. Brake pole
E. Armature
F. Re-gap shim
G. Rotor
H. Gap
Figure 4-27
Always wear adequate eye protection when servicing
the mower.
Figure 4-28
A. Gap between the rotor and armature face must be
greater than .070" prior to shim removal.
Figure 4-29
Do not remove brake pole from field shell/armature.
The brake pole tracks match with the clutch brake
and need to continue to match after shim is removed
to ensure proper brake torque. Figure 4-27
