  Q: How to replace the valve rocker arm and push rods on Chevrolet Silverado 3500 Classic?

  A:

  After removing the Rocker Arm cover position all rocker arms pushrods and pivot support in a rack where their original positions can be preserved before starting the replacement process. Unbolt all Rocker Arm pieces then take off the rocker arms and Rocker Arm pivot support as well as the pushrods. Inspection of rocker arms and pushrods can be followed by cleaning procedures. After reinstallation all components must return to their original positions because valve lash emerges as an automatic result without requiring adjustments. A clean engine oil coating should be applied to both the Rocker Arm sections and pushrods followed by flange lubrication of the Rocker Arm bolt. Screw in the Rocker Arm pivot support while checking that pushrods drop into valve lifter sockets and manholes of the rocker arms yet refrain from bolting the Rocker Arm shafts. The Crankshaft should be rotated to reach its top dead center compression point with the number one Piston which sets the number one cylinder rocker arms beyond their lift range and positions the Crankshaft sprocket key at 1:30. Apply 30nm torque to all Rocker Arm bolts securing the cylinders 1, 2, 7 and 8 exhaust valves and the cylinders 1, 3, 4, 5 intake valves while the engine maintains its current position. Apply 30 nm torque to the Rocker Arm bolts of cylinders 3, 4, 5 and 6 exhaust valves after rotating the Crankshaft by 360 degrees and apply 30 nm torque to the bolts of cylinders 2, 6, 7 and 8 intake valves at this point. Rocker Arm cover must be installed at the end of the process.
