Rocker Arm Operation:
A cast or stamped preformed actuator that pivots either on a stud or on a shaft. This pivoting motion caused by the cam lobe eccentric enables the pushrod to change the upward movement of the pushrod stem into the downward movement of the valve. Mounted on top of the cylinder head, it transfers motion from the camshaft to the valves.
How To Instructions:
- Check for obvious problems.
- Do the jobs that fix your car.
- Out with the old, in with the new.
