Clutch Air Gap Inspection and 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 arma-
ture and the rotor must be set at .5 mm (.020 inch).
If the air gap is too narrow, the clutch armature may
drag when disengaged, causing premature failure.
If the air gap is too 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 needed.
1. Locate the three inspection windows (A) on the
clutch.
2.
A
Insert a .5 mm (.020 inch) feeler gauge through
the inspection window and into the slot between
the armature and the rotor.
3. Tighten or loosen the clutch adjustment nut (B) as
needed to achieve the .5 mm (.020 inch) air gap.

WARNING
If the power unit is not adequately supported, the
unit could fall and trap or crush a person or append-
age, causing severe injury or death.
3. Lift up the corner of the power unit and secure
with a jack stand.
4. Remove the lug nuts and lift the wheel o the
mounting studs.
Wheel Installation:
1. Place the wheel onto the mounting studs with the
hub side of the rim against the axle hub. NOTE:
if the wheel is equipped with a single valve stem,
the valve stem will be to the outside of the power
unit. If the wheel is equipped with dual valve
stems, there is a decal on the rim that indicates
the hub side of the rim.
2. Install the lug nuts and tighten by hand until the
