2. Apply a dab of grease to the formed groove in
the thrust washer. Slide the washer onto the
cam sha so the short drive pin is seated in
the groove. The grease will hold the washer in
position. Pivot the exhaust cam lever toward
the push rod bore, then insert the cam sha into
the counterbore of the crankcase. Make sure the
pin stays in the groove of the thrust washer. See
Figure 10-27.
