2006 GMC Sierra 1500 Harmonic Balancer Parts Questions & Experts Answers

• Q: How to replace the harmonic balancer on 2006 GMC Sierra 1500?

  A: As the first step to replace the crankshaft balancer you must remove both Drive Belt and cooling fan from the engine. Before using the crankshaft balancer removal tool you need to install a shorter bolt exclusively made for the crankshaft balancer bolt in the crankshaft to maintain its safety. Initial steps require cranking the crankshaft balancer bolt with washer while also removing the crankshaft pulley bolts together with their pulley. The crankshaft balancer remover and installer (J 23523-F) allows you to take off the balancer following its specified method while you must place the plate and bolts onto the balancer before tightening its bolts to 25 nm (18 ft. Lbs.). The j 23523-f forcing screw installs onto the plate before a clockwise rotation to eliminate the balancer component. Record the positions along with length of all balancer weights during removal before cleaning and inspecting the balancer as needed. When reinstalling the crankshaft front cover seal apply a small amount of grease to secure the seal before placing the correct weight position of the balancer. Form gm p/n 12346141 (Canadian P/N 10953433) adhesive should be applied into the crankshaft balancer keyway before placing the balancer on the crankshaft by setting the keyway into alignment with the crankshaft balancer key. The j 23523-f tool allows installation of the balancer by pressing it onto the crankshaft followed by securing the j 23523-f plate along with bolts at 25 nm (18 ft. Lbs.). After installing bearin, nut and washer and forcing screw to the j 23523-f tool the technician should turn the nut clockwise until the crankshaft position sensor reluctor ring receives complete contact with the hub. After placing the j 23523-f tool aside, mount the crankshaft pulley together with its bolts. First tighten these by hand before achieving 58 nm (43 ft. Lbs.) torque. To achieve proper installation position the crankshaft balancer washer bloc with its face resting against the engine direction. After adding the washer and bolt tighten it to 95 nm (70 ft. Lbs.). Reinstall the cooling fan combined with the Drive Belt.
