After removing the rotor, remove the engine start drive gear
if it is damaged. To do so, you must remove the small
Woodruff key that indexes the engine start drive gear to the
crankshaft. Gently tap the Woodruff key out with a
screwdriver and a hammer.
Remove the engine start drive gear. If you need a
replacement engine start drive gear, please call us at 909 445
0900.
Assembly is the reverse of disassembly. When assembling the left engine cover to the engine, use a
new gasket (please call us at 909 445 0900 if you need a new gasket). Apply Loctite to the rotor
crankcase bolt and torque the rotor crankcase bolt to 45 ft-lbs. Torque the engine cover mounting and
countershaft cover bolts to 7 ft-lbs.
