Cylinder head and Camshafts

a. Install the new cylinder head gasket. Install the dowel pins and "o-rings".

b.   Install the cylinder head onto the cylinder. Pull the cam chain through the cylinder head as it is installed. Tie the cam chain so that it does not fall into the crankcase.

c.   Place the upper cylinder head nuts and washers in place. Follow the illustration for the proper tightening sequence. Torque all nuts in two stages and final torque the upper nuts to the specification.

Tightening torque: 2.0 m-kg (14.5 ft-lb)

Don't forget the lower nuts on the front and rear of the cylinder head. Torque to the specification.

Tightening torque: 1.0 m-kg (7.2 ft-lb)

1. Copper washers

NOTE
Tighten the nuts in two stages, 1/2 torque value and then full torque value. Also lubricate the bolt threads with the engine oil to achieve proper torque values.

d. Install the front cam chain guide being certain that it is in its holder down below.

1. Lock washer 2. Front cam chain guide

e. Rotate the engine in a counterclockwise direction until the crankcase pointer and "T" mark on the timing plate are aligned.

f.   With the cylinder No. 1 and 4 at the top dead center, slip the cam chain over the sprocket.

g.   Lubricate at! cam caps and cam bearings surfaces liberally with oil.

h. Place the cam caps in their proper positions. The caps are identified "1-1" through "I-4" for intake and "E-1" through "E-4" for exhaust. Install the bolts only finger tight.

CAUTION:
The cam caps must be tightened evenly or damage to the cylinder head, cam caps and cam will result. The spaces between the caps and cylinder head should be equal.

i. Torque the cam cap bolts in two stages and final torque to specification.

Tightening torque: 1.0 m-kg (7.2 ft-lb)
