  Q: How to replace the Harmonic Balancer on 4.8L, 5.3L, and 6.0L engines on Chevrolet Silverado 2500?

  A:

  After collecting the crankshaft balancer remover (J 41816) and crankshaft end protector (J 41816-2) along with the Flywheel holding tool (J 42386-A) and crankshaft balancer and sprocket installer (J 41665) and angle meter (J 45059), one can proceed with the crankshaft balancer replacement on 4.8l, 5.3l, and 6.0l engines. Start by disconnecting the air conditioning Drive Belt and the lower Fan Shroud followed by removing the Starter motor then position the teeth of Flywheel holding tool (J 42386-A) to hook on the engine Flywheel. Use the crankshaft balancer remover (J 41816) together with the crankshaft end protector (J 41816-2) to remove the crankshaft balancer along with the crankshaft balancer bolt which must be maintained for later reinstallation. The crankshaft balancer requires cleaning along with thorough inspection before you install it. The balancer must sit straight on the crankshaft before using the crankshaft balancer and sprocket installer (J 41665) to install it while ensuring proper assembly of the threaded rod and nut and washer. First tighten the previously used crankshaft balancer bolt to 330 nm (240 ft. Lbs.) before removing it. A measurement of the balancer installation status should be performed to check if it is properly seated; redo the installation if necessary. New crankshaft balancer bolts must be installed and taped first to 50 nm (37 ft. Lbs.) then measured to 140 degrees using the angle meter (J 45059). The last step involves removing the Flywheel holding tool (J 42386-A) with its bolts while reinstalling the Starter motor and lower Fan Shroud and air conditioning Drive Belt then conducting the crankshaft position system variation learn procedure.
