Reassembly

Install Intake Cam on Cam Shaft

1. Lift the intake cam lever and install the intake cam
gear onto the intake cam shaft, engaging the slot
with the upper drive pin. Rotate the gear and shaft
so the "IN" timing mark on the cam gear is in the
4 o'clock position. Install the thrust washer onto
the cam shaft. See Figure 10-26.
Figure 10-26. Installing Intake Cam Gear and
Thrust Washer.

Install Crank Gear

1. Orient the crankshaft so the key is in the 12
o'clock position. Hold the crank gear with the
timing marks visible and slide it onto the
crankshaft and key, so the timing marks on the
crank gear align with the timing marks on the
cam gears. See Figure 10-27.

Install Flywheel Side Oil Seal

1. Lubricate the outside diameter and lip of the
flywheel end oil seal. Support the closure plate
and install the oil seal. Using a seal driver, drive
the seal to a depth of 5 mm (0.196 in.) in the seal
bore. See Figure 10-28.

Install Closure Plate Gasket, Closure
Plate, and Wiring Harness
NOTE: The special gasket used between the closure
1. Make sure the sealing surfaces of crankcase and
closure plate are clean, dry, and free of any nicks
or burrs. Install a new closure plate gasket onto
the crankcase.
Important!
2. Apply grease to the outside flat surfaces of the
balance weight guide shoe. Position the guide
shoe so the solid end is toward the crankshaft.
See Figure 10-29. Make sure the guide shoe
stays in this position during the next step.
3. Ensure the gasket, cover plate, and governor
gear assembly, have been properly assembled to
the closure plate (refer to Section 9). Start the
closure plate onto the crankcase. Be sure the
guide shoe is aligned with the guide channel in
the closure plate, and the cam shafts and
governor gear shaft are aligned with their mating
bearing surfaces. See Figure 10-29. As the plate
is lowered into final position, rotate the crankshaft
slightly, if necessary, to help engage the governor
gear.
Not For Resale
plate and crankcase controls crankshaft
endplay, no shimming is required. Do not
use RTV sealant in place of the gasket.
