Clutch Air Gap Inspection & Adjustment
The electric clutch is activated by the PTO switch to
engage or disengage power to belt driven attach-
ments. The clutch also provides braking action to
stop the attachment when the PTO is disengaged or
the operator presence circuit is interrupted.
For proper operation, the air gap between the
armature and the rotor must be set at .020” (.5 mm).
If the air gap is to narrow, the clutch armature may
drag when disengaged, causing premature failure.
If the air gap is to wide, the clutch may not engage
correctly or it may disengage when it becomes hot.
Check the air gap annually and adjust the clutch air
gap as necessary.
1. Locate the three inspection windows (A) on the
clutch.

2. Place a .020” (.5 mm) feeler gauge in the slot
