Valve Springs and Valves

Valve Installation

CAUTION: When tapping the valve stems tap it at a right angle to the stem end so as not to bend the stem.
• When installing the valves in the cylinder head, coat the valve stems with oil before inserting them into valve guides, and make sure the valves move up and down smoothly.
• When the valves and springs are in place, lightly tap the end of each valve stem two or three times to ensure proper seating of the valve and valve keepers.

Camshaft/Seal and Rocker Arms

Installation

CAUTION:
•   Make sure that all the rockers are in alignment with the valves when torquing the rocker assembly bolts.
•   To prevent the rocker arm assembly from coming apart, leave the cam holder holding bolts in the holes.

1. After wiping down the cam and journals in the cylinder head, lubricate both surfaces and install the camshaft.

2. Set the camshaft and camshaft seal as shown below.

3. Install the camshaft seal with the open side (spring) facing in.

Lubricate the cam lobes after reassembly.
