Valve Rocker Arm, Shaft, and Push Rod Installation

1. Install the valve pushrods with the copper-colored, painted or marked end upwards.

IMPORTANT: Ensure that the ball ends of the valve pushrods seat in the valve rocker arms.

NOTICE: Install the valve pushrods with the copper-colored, painted, or marked end up in order to avoid damage or premature wear.

2. Install the valve rocker arm shaft assembly.

3. Install the bolts.
3.1. Rotate the crankshaft, until the mark on the crankshaft balancer is at the 2 o'clock position.
3.2. Rotate the crankshaft counterclockwise 88 mm (3 1/2 inch), aligning the crankshaft balancer mark with the first lower water pump bolt, at approximately the 12:30 position.
3.3. This procedure will position the engine so that no valves are close to a piston crown.
3.4. Finger-tighten the bolts.
Alternately tighten the bolts to 55 Nm (40 ft. lbs.).

NOTICE:
^ Improper installation of the valve rocker arm shaft bolts may cause valve rocker arm shaft breakage and piston to valve contact.
