Crankshaft End Play
Check and adjust crankshaft end play with spacer
shims. Three thicknesses are available: 0.6, 0.8 and
1.0 mm (0.024, 0.031 and 0.039 inch). To pick the
best shim:
1. Measure and record the A and B distances
(Figure 9-12). Figure 9-13 shows a method for
determining the B distance. B is equal to Read-
ing 1 minus Reading 2.
2. The thickness of the compressed gasket is
0.014 inch (0.36 mm). Thus:
3.
A + 0.014 inch – B = Clearance (inch)
[A + 0.36 mm – B = Clearance (mm)]
4. Thus, to obtain an end play of 0.008 inch
(0.2 mm):
5.
Clearance (inch) – 0.008 inch = Shim Thickness (inch)
[Clearance (mm) – 0.2 mm = Shim Thickness (mm)]
