Figure 11-9. Torquing #1 Rod Cap.
NOTE: Make sure to align the chamfer of the
connecting rod with the chamfer of its
mating end cap. When installed, the flat
faces of the connecting rods should face
each other. The faces with the raised rib
should be toward the outside.
6. Repeat the above procedure for the other
connecting rod and piston assembly.
Install Camshaft
1. Inspect the edges of the camshaft keyway, make
sure they are not nicked or burred. Use a seal
protector (11/16") to prevent damaging the seal
lips, or dislodging inner spring when the
camshaft is installed. Cellophane tape over the
keyway is also recommended. See Figure 11-10.

Protector.
2. Lubricate the camshaft bearing surfaces of the
crankcase and camshaft with engine oil. Apply a
small amount of grease to the lips of the oil seal.
3. Rotate the crankshaft and position the timing
mark of the crankshaft gear at the 12 o'clock
position.
4. Turn the governor cross shaft clockwise until the
lower end of shaft contacts the crankcase (#1 side).
Make sure the cross shaft remains in this position
while installing the camshaft.
5. Slide the camshaft into the bearing surface of the
crankcase, positioning the timing mark of the
camshaft gear at the 6 o'clock position. Make sure
that the camshaft gear and crankshaft gear mesh,
and the timing marks are aligned. See Figure
11-11.
