  Q: What tools are required to service and repair the pushrod and valve rocker arm on Buick Lucerne?

  A:

  The repair and servicing of valve Rocker Arms together with push rods requires torque angle meter (J 45059) as essential equipment. Use a clean surface along with proper storage to place the valve Rocker Arm cover(s) and valve Rocker Arm bolt(s). Then continue with the valve Rocker Arm(s) removal and valve Rocker Arm guide plate removal if all rocker arms need replacement. Complete the task by removing the push rod(s). Start by removing the valve Rocker Arm(s) together with the valve Rocker Arm guide plate when replacing all rocker arms then proceed to remove the push rod(s). You need to clean the push rods and valve rocker arms together with their bolts as well as guide plates in suitable solution to remove all thread adhesive from the valve Rocker Arm bolts. After clearing the Cylinder Head tapped holes with compressed air distribute prelube oil on the push rod endings before repositioning them to their original slots. The valve Rocker Arm guide plate(s) and the valve Rocker Arm(s) require installation after threadlock application to the Rocker Arm bolt threads. Use the torque angle meter (J 45059) to tighten valve Rocker Arm bolts to 15 n.m (11 lb ft) until reaching an additional 90 degrees angle then install the valve Rocker Arm covers and perform a noise inspection of the valve train system.

  Q: How to replace the pushrods and valve rocker arm on Buick Lucerne?

  A:

  The first step to replace valve Rocker Arm and push rods begins by extracting the valve Rocker Arm covers. Rephrase the section by first loosening valve Rocker Arm bolts then removing rocker arms along with pushrods while keeping in mind that intake push rods measure 147.51 mm (5.81 in) and exhaust push rods measure 154.87 mm (6.1 in). A single application of prelube at the Pushrod ends will guarantee correct insertion in the lifter bore. Apply prelube on the surfaces that make contact in the rocker arms before installation. Installation of newly reconditioned Cylinder Head or its parts could require shims (part number 88894006) under valve Rocker Arm pedestals. Rocker arms should be installed followed by tightening the Rocker Arm bolts. The last step involves placing back the valve Rocker Arm covers.
