8.7 Adjusting Crankshaft End Play
See Graphic: wc_gr001906
Adjust the end play to 0.2 mm (0.008 in.) using the proper spacer.
Determine the proper spacer in the following manner:
8.7.1 Measure the height “A”. Distance from main bearing cover mating
surface (a) to the inner race of the ball bearing (b).
8.7.2 Measure the depth “B”. Distance from the crankcase mating surface
(c) to the crankshaft gear (d).
B-A = side clearance
Side clearance - 0.2 mm (0.008 in.) = thickness of crankshaft shim.
Spacer shims are available in the following thicknesses:
0.6 mm (0.024 in.)
0.8 mm (0.031 in.)
1.0 mm (0.039 in.)
8.7.3 Reference: crankcase (e); crankshaft (f); depth gauge (g).
