Reassembly
Install Flywheel End Oil Seal and
Camshaft Oil Seal
1. Check to make sure that there are no nicks or
burrs in the crankshaft and camshaft seal bores
of the crankcase.
2. Apply a light coat of engine oil to the outside
diameter of the flywheel end oil seal.
3. Install the oil seal into the crankcase using a seal
driver. Make sure the oil seal is installed straight
and true in bore, until the tool bottoms against
the crankcase. See Figure 11-1.

Using Tool.
4. Apply a light coat of engine oil to the outside
diameter of the camshaft oil seal.
5. Install the camshaft oil seal to a depth of 1.0-1.5
mm (0.039-0.059 in.) below the top of the seal
bore. See Figure 11-2. Do not bottom the seal in
the bore or the oil passage may be obstructed.

Install Governor Cross Shaft
1. Lubricate the governor cross shaft bearing
surfaces in the crankcase with engine oil. Apply a
small amount of grease to the lips of the oil seal.
2. Slide the small lower washer onto the governor
cross shaft and install the cross shaft from the
inside of the crankcase. See Figure 11-3.
Figure 11-3. Installing Governor Shaft.
3. Install the nylon washer onto the governor cross
shaft, then start the push-on retaining ring. Hold
the governor shaft up in position, then place a
0.25 mm (0.010 in.) feeler gauge on top of the
nylon washer, and push the retaining ring down
the shaft to secure. Remove the feeler gauge,
which will have established the proper end play.
See Figure 11-4.
