CLUTCHING
4.36
Installation
1. Install proper number of spacer washers on jackshaft
between clutch and jackshaft bearing.
Inspect Jackshaft
Bearing
Excessive vibration or abnormal drive belt wear can
be caused by a worn bearing or jackshaft on the driven
clutch side. To inspect bearing fit, watch the bearing
area closely as you try to force the jackshaft up and
down. If movement is detected, disassemble to
determine which parts are worn. Replace the
jackshaft if the new bearing is loose on the shaft. The
bearing should be greased at 1000 mile (1600 km)
intervals and before storage.
NOTE: Spacer washers between driven clutch and jack-
shaft bearing set the offset. Refer to adjustment proce-
dure on page 4.40 to adjust offset between the drive and
driven clutch.
2. Lightly grease jackshaft keyway or spline. With
square key in place slide clutch onto jackshaft.
3. Install spacer, bolt and washer to hold driven clutch in
place.
4. P-85 driven clutches should float from side to side
(.040-.080s (1-2 mm)). Without a slight free float,
jackshaft bearings could be side loaded, causing
premature bearing failure.
