How to remove and install rocker arms and rocker arm shaft assembly?

First, remove the rocker arm covers, then the rocker arm shaft assembly bolts and finally the rocker arm shaft assembly. The nylon arm retainers have to be removed in order to get the rocker arms off the shaft. With a pair of pliers, this can be done or they can be broken by hitting them below their head with a chisel. After that, take out the rocker arms from the shaft making sure they are put in order. Each rock arm also has an external rib which points away from between each pair of rocker arms up to the one at each end closest to its respective bolt on the opposite side of a valve cover. If you are installing new rocker arms, be aware that replacement units would have R or L on them indicating right or left side installation only and they cannot be interchanged. Fit on oil-lubed shaft then install it back onto both ends and tighten nuts to 25 ft lbs (32 Nm). In case you should decide on installing new retainer using hammer and drift 1/2 inch diameter or bigger.

To replace, perform removal steps conversely and adjust Pontiac engines' rocker ball retaining nut up to 20 ft.lbs (26 Nm). On Chevy engines, start nut onto stud and set valves according. For 263 (Diesel), 307, 350 (Gas and Diesel), and 403 Oldsmobile engines, start by removing valve covers. Each pair of rocker arms are taken out by first removing two bolts that keep the pivot attached to head for every cylinder; this procedure is repeated twice for other pairs of rockers arms so that for proper reassembly all should be kept in order. Ensure that lifters are off cam lobe and valves are closed before installing rocker arms. Attach remote starter or have an assistant bump engine over until valves close for each cylinder. With valves closed install paired rocker arms lubricating all pivot and wear points between them with white grease before installation.

Buick Regal Rocker Arm

Rocker Arm in Buick Regal automobiles is a functional part of the valvetrain system; it helps in the conversion of the movement from pushrod to the intake and the exhaust valves. Usually made from stamped steel or aluminium, these parts translate the plunger's movement from the vertical to the downward force required to open the valves. For high-RPM engines, aluminium is used because of its low density whereas for diesel engines, cast iron or forged carbon steel is used. There are different types of rocker arms, including the roller rockers, that utilizes needle bearings to minimize the contact points between them thereby minimize wear and tear and increase efficiency of the rocker arms over other kinds. The rocker ratio of current engines stand between 1.5:1 to 1.8:1 and this affords higher camshaft lift which in turn raises performance level. Traditionally, such ratios as 1:1 were typical up to the 50s of the previous century. Larger diameter fulcrum bearings are also used in engines where higher RPMS are encountered to deal with the stresses required and increase the life of the part adding to the functionality of the Rocker Arm.

Each OEM Buick Regal Rocker Arm we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
