Note

Allow approximately .001 in. for pull of rivets.

When correct clearance between washer and starter clutch is obtained, feed rivets into countersunk holes from inside of sprocket shell. Head rivets until flush to .010 in. maximum above face of starter clutch. Seal rivets on both sides using a solvent-proof sealer.

With lip facing in, press oil seal (17) into clutch shell.

ASSEMBLING CLUTCH (Fig. 4B-8)

Assembly is essentially the reverse order of disassembly. Be certain that all parts are clean, free of oil and dry before reassembling.

Press 1966 and earlier extension (29) in clutch gear using aluminum paint as a sealer and install hub nut "O" ring (28). Install oil seal (27). Do not forget to insert clutch release rod - left (9, Fig. 4B-6). Apply a light coat of grease to needle roller bearings, and compensating sprocket shaft extension and install spacer (20 or 20A) and "O" ring (18) on clutch gear. Assemble clutch sprocket, front chain and compensating sprocket in one move. Be sure chain adjuster is positioned loose behind chain. Reassemble compensating sprocket as described under "Assembling

Compensating Sprocket."
