4. Make sure Fly stamping on piston is facing towards
flywheel side of engine. Use a hammer with a rubber
grip and gently tap piston into cylinder. Be careful
that oil ring rails do not spring free between bottom
of ring compressor and top of cylinder.
5. Install inner rod cap to connecting rod using screws.
Three different types of connecting rod bolts have
been used and each has a different torque value. If 8
mm straight shank type bolts are used, torque in
increments to 22.7 N·m (200 in. lb.). If 8 mm step-
down bolts are used, torque in increments to 14.7
N·m (130 in. lb.). If 6 mm straight shank bolts are
used, torque in increments to 11.3 N·m (100 in. lb.).
Illustrated instructions are provided in service rod
package.
6. Repeat above procedure for other connecting rod
and piston assembly.
Install Camshaft
1. Liberally apply camshaft lubricant to each cam lobe.
Lubricate camshaft bearing surfaces of crankcase
and camshaft with engine oil.
2. Position timing mark of crankshaft gear at 12 o'clock
position.
3. Turn governor cross shaft clockwise until lower end
of shaft contacts cylinder. Make sure cross shaft
remains in this position while installing camshaft.
4. Slide camshaft into bearing surface of crankcase,
positioning timing mark of camshaft gear at 6 o'clock
position. Make sure camshaft gear and crankshaft
gear mesh with both timing marks aligned.
Determining Camshaft End Play
1. Install shim removed during disassembly onto
camshaft.
2. Position camshaft end play checking tool on
camshaft.
3. Apply pressure on camshaft end play checking tool
(pushing camshaft toward crankshaft). Use a feeler
gauge to measure camshaft end play between shim
spacer and checking tool. Camshaft end play should
be 0.076/0.127 mm (0.003/0.005 in.).
4. If camshaft end play is not within specified range,
remove checking tool and replace shim as
necessary.
Several color-coded shims are available:
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.)
5. Reinstall end play checking tool and recheck end
play.

1. Check to make sure that there are no nicks or burrs
in crankshaft bore of oil pan.
2. Apply a light coat of engine oil to outside diameter of
