A replacement procedure for crankshaft balancer starts by disconnecting the
Battery Cable's negative end then continuing with removing both the
Fan Shroud assembly and
Drive Belt. After removing the crankshaft balancer bolt with its washer you must detach the bolts which hold the Crankshaft Pulley in place. Use the balancer remover and installer (J 23523-F) to uninstall a crankshaft balancer by mounting the j 23523-f plate with bolts onto the component before torquing bolts to 25 nm (18 ft. Lbs.), then placing the j 23523-f forcing screw into this plate. To extract the balancer the j 23523-f forcing screw should be rotated clockwise before tool removal. Check the position and length of front groove pins when present before thoroughly cleaning all parts for inspection. The front seal of the crankshaft front cover requires application of grease during reinstallation when using the existing seal while maintaining proper position of the front groove pin. Place gm p/n 12346141 adhesive or an equivalent substance onto the crankshaft balancer keyway then position this mark with the balancer key before you fasten the balancer to the crankshaft. Start by placing the j 23523-f onto the crankshaft using its plate and bolts which need to be tightened to 25 nm (18 ft. Lbs.). Proceed to add the j 23523-f screw then the bearing and washer followed by the nut until the balancer hub rests against the crankshaft position sensor reluctor ring during a clockwise rotation. The j 23523-f should be removed while you install the Crankshaft Pulley and bolts with 58 nm (43 ft. Lbs.) torque value. Then align the crankshaft balancer washer crown to face outward from the engine before installing the washer and bolt which must be tightened to 95 nm (70 ft. Lbs.). Reinstall the Drive Belt before adding the Fan Shroud assembly and then reattach the battery negative cable.
