  Q: How to replace the pushrod and valve rocker arm on Chevrolet Suburban 2500?

  A:

  Before replacing the valve Rocker Arm and push rod mark the components initially then sort them properly to ensure their correct restoration in the final assembly process. The repair must start by taking off the valve Rocker Arm cover and progressing to the valve Rocker Arm nuts and balls together with the valve rocker arms. The exhaust valve pushrods extend beyond the length of intake valve pushrods. After removing valve pushrods and Pushrod guides with valve Rocker Arm studs, you should clean and examine both rocker arms and pushrods. The installation of valve Rocker Arm stud-to-Cylinder Head threads requires gm U.S. P/N 12346004 or canada P/N 10953480 or equivalent sealant material. Install Pushrod guides together with valve Rocker Arm studs while tightening the studs until they reach 50 nm (37 ft. Lbs.). During the installation procedure remember that exhaust valve pushrods exceed the length of intake valve pushrods. The valve pushrods need installation before coating the valve Rocker Arm surfaces along with the valve Rocker Arm ball bearing components using gm u.s P/N 12345501, canada P/N 992704, or equivalent. Put the valve rocker arms along with valve Rocker Arm balls and valve Rocker Arm nuts into place before tightening them slowly to 25 nm (18 ft. Lbs.) to ensure the tips of the rocker arms remain on top of the valve tips. Place the valve Rocker Arm cover as your last step.
