  Q: How to replace the harmonic balancer on Chevrolet Avalanche 1500?

  A: Tool requirements for replacing the crankshaft balancer include crankshaft balancer remover (J41816), crankshaft end protector (J41816-2), Flywheel holding tool (J42386-A), crankshaft balancer and sprocket installer (J41665) and torque angle meter (J36660-A). Begin your replacement of the crankshaft balancer by disconnecting the air conditioning Drive Belt when installed or proceed with the accessory Drive Belt if absent. The maintenance process demands next the removal of the lower shroud and Starter motor alongside the correct insertion of Flywheel holding tool (J42386-A) between teeth on the engine Flywheel. Fasten the j42386-a and bolts together by using a m10-1.5 x 120 mm piece and a m10-1.5 x 45 mm piece then tighten them to 50 nm (37 ft. Lbs.). Use the crankshaft balancer bolt during reinstallation because you will need it for the procedure. The crankshaft balancer remover (J41816) and crankshaft end protector (J41816-2) need to be used for removing the crankshaft balancer while cleaning and checking the part is done when needed. To install the Flywheel holding tool (J42386-A) position its teeth correctly onto the engine Flywheel. Position the crankshaft balancer onto the crankshaft by using the crankshaft balancer and sprocket installer (J41665). After tightening the used crankshaft balancer bolt to 330 nm (240 ft. Lbs.), remove it to verify that the crankshaft nose penetrates 2.4-4.48 mm (0.094-0.176 inch) into the balancer bore. Perform another installation sequence of the j41665 if required. Secure the new crankshaft balancer bolt by tightening it to 50 nm (37 ft. Lbs.) followed by torque angle meter (J36660-A) usage to achieve 140 degrees of torque. After you remove the Flywheel holding tool (J42386-A) and bolts the procedure requires you to reinstall the Starter motor and lower Fan Shroud along with the accessory Drive Belt when the vehicle is not equipped with a/c system and the a/c Drive Belt when it is equipped. Finish by performing the crankshaft position system variation learn procedure.
