Installation

1. Ensure No. 1 piston is on TDC of compression stroke and ignition rotor is at
position noted at removal. Ensure all gasket mating surfaces are clean. Properly
position new cylinder head gasket on cylinder block. Carefully install cylinder head.

2. Install cylinder head bolts finger tight. Tighten cylinder head bolts in sequence to specifications in 5 steps. See Fig. 4. See TORQUE SPECIFICATIONS.

3. Install camshaft in cylinder head. Rotate camshaft until knock pin in front of
camshaft is at 12 o'clock position. Install rocker arm shafts. Rocker arm shafts
must be installed to original location and position. Evenly tighten rocker arm
shaft bolts from center working outward to specifications in 2 or 3 steps.

4. Ensure camshaft knock pin is at the 12 o'clock position. Position No. 2 hole on camshaft sprocket at 12 o'clock position in alignment with knock pin on
camshaft and install timing chain on sprocket. See Fig. 5.

5. The timing chain has a Silver marked link which must align with the No. 2 dot
on outer edge of camshaft sprocket. See Fig. 5. Install camshaft sprocket with
timing chain on camshaft. Ensure No. 2 hole of camshaft sprocket is fitted to camshaft knock pin at the 12 o'clock position.

6. Install camshaft sprocket bolt and tighten to specifications. Apply sealant to front saddle of cylinder head where rubber plug seats and install rubber plug in head. Adjust valves.

See VALVE CLEARANCE ADJUSTMENTS
7. With valves adjusted, install new valve cover gasket. Install valve cover and bolts. Tighten valve cover bolts evenly to specifications.

NOTE:
DO NOT rotate camshaft or crankshaft with timing chain disconnected, as valve(s) may be damaged due to insufficient clearance with pistons.
