Checking/Setting Camshaft End Play
1. Install the shim removed during disassembly
onto the camshaft.
2. Position the end play tool on the camshaft.
3. Apply pressure on the end play checking tool
(pushing the camshaft toward the crankshaft).
Use a feeler gauge to measure the end play
between the shim and the end play tool. See
Figure 11-12. The camshaft end play should be
0.076/0.127 mm (0.003/0.005 in.).
Figure 11-12. Checking Camshaft End Play with
Tool.
4. If the camshaft end play is not within the
specified range, remove the original shim and
reinstall the end play tool. Use a feeler gauge to
determine the clearance between the camshaft
and the tool. Subtract 0.100 mm (0.004 in) from
the measured clearance to obtain the required
shim thickness. Refer to the table below and
install the shim that matches the calculated
thickness. See Figure 11-13. Repeat steps 1-3 to
verify that the correct end play exists.

Camshaft Shims
White: 0.69215/0.73025 mm (0.02725/0.02875 in.)
Blue: 0.74295/0.78105 mm (0.02925/0.03075 in.)
Red: 0.79375/0.83185 mm (0.03125/0.03275 in.)
Yellow: 0.84455/0.88265 mm (0.03325/0.03475 in.)
Green: 0.89535/0.99345 mm (0.03525/0.03675 in.)
Gray: 0.94615/0.98425 mm (0.03725/0.03875 in.)
Black: 0.99695/1.03505 mm (0.03925/0.04075 in.)
Oil Pump Assembly
The oil pump is mounted to the inside of the closure
plate. If service was required, and the oil pump was
removed, refer to the assembly procedures under "Oil
Pump Assembly" in Section 10.
Governor Assembly
The governor assembly is located inside the closure
plate. If service was required, and the governor was
removed, refer to the assembly procedures under
"Governor Assembly" in Section 10.
Thrust Bearing, Washer and Shim
Some specifications use a thrust bearing, thrust
washer, and shim to control the end play of the
crankshaft. See Figure 11-14. If these items were noted
during disassembly, make sure they were reinstalled
in the proper sequence, as illustrated. A different
procedure must be followed to check and adjust
crankshaft end play on these models.
