How to remove the Pushrod and Rocker Arm on 4.3L V6 engine on Chevrolet Avalanche?

You can start by removing the rocker arms, which will be loosened and stored in containers labeled as rocker arm support bars. Keep their different pushrods separately. If necessary, inspect each rocker arm for damage on the pivoting area and cracks or wear on the bearing surface; after that replace any defective ones, making sure roller bearings rotate freely. Look at the pushrods to see if they have cracks, are too worn out or bent. For reinstalling, lube the push rods and put them back into their original position with full seating in the lifter being noted. After that, place back the rocker arm support with arrows up and also wipe off grease from valve stems and ends of pushrods. Then fit all rocker arms one by one, lubricating roller bearings lightly and tightening the rocker arm bolts evenly according to a specified torque. Lastly, you can start your engine up and check it for oil leaks or noises from the valve train mechanism.

Chevrolet Avalanche Rocker Arm

The Rocker Arm in Chevrolet Avalanche automobiles plays a crucial part of an automobile engine system particularly the valvetrain; which is responsible for moving the pushrod and hence the opening and closing of the intake and exhaust valves. Conventionally, made of stamped steel or aluminum, these parts translate the vertical 'pushrod' travel into the right vertical movement to open the valves. Aluminum is used where the engine is required to run at high RPM, since it is light in weight, while cast iron or forged carbon steel is used in the diesel engines since they are strong. Some styles of rocker arms are called roller rockers and consist of the contact points containing needle bearings to decrease both friction and wear. The rocker ratio that vary from 1.5:1 to 1.8:1 in modern engines increases the lift of the camshaft to improve on performance. New superior bearings are also used in the fulcrum-cum-Rocker Arm in the harness to meet the elevated stress conditions in high-RPM engines and to provide an excellent lifespan of Rocker Arm system.
