Driveshaft and Clutch Group Disassembly Procedure

Disassemble the driveshaft and clutch group only when necessary in order to clean, inspect, or replace one or more parts of the group separately.

Removing The Pinion Stop:

1. Remove the stop rings and the pinion stop.
1.1. Position the driveshaft and clutch group on a work bench with the internal gear end down.
1.2. Place an open tube with a diameter (2) of 22 mm (0.87 in) over the slightly smaller 14.2 mm (0.60 in) diameter (1) of the shaft.
1.3. With the tube, drive the pinion stop toward the clutch drive until the pinion stop clears the stop ring.
1.4. Pry the stop rings out of the driveshaft groove. Slide the stop rings off the shaft, being careful not to scratch the driveshaft.
1.5. Inspect the edges of the shaft groove for burrs. Burrs may make removal of the pinion stop and clutch drive assembly difficult.
1.5.1. If burrs are found, use a file in order to carefully remove the burrs without damaging the base metal.
1.5.2. Thoroughly clean away any metal filings.
1.6. Slide the pinion stop off the driveshaft. Discard the old pinion stop and stop rings.
