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

  A:

  One should begin crankshaft balancer replacement by removing both the Drive Belt and cooling fan. A shorter bolt matching the crankshaft balancer bolt should be inserted into the crankshaft before using j 23523-f (J 23523-F) to prevent crankshaft damage. Begin by taking out both the crankshaft balancer bolt along with washer then move to extract the Crankshaft Pulley bolts and pulley. The procedure of removing and reinstalling the crankshaft balancer requires j 23523-f which should have its j 23523-f plate and bolts installed on the balancer while torquing bolt sets to 25 nm (18 ft. Lbs.). You should insert the j 23523-f forcing screw into the plate before rotating it clockwise to take out the balancer. Record the position and length of each balancer weight before cleaning and inspecting the balancer unit. If using a reused seal on the crankshaft front cover remove a small amount of grease for effective sealing. Apply a minimal amount of grease to the crankshaft front cover seal after ensuring the balancer weight(s) occupy proper positions during seal reuse. Apply adhesive into the crankshaft balancer keyway to seal the joint and position the keyway properly for the balancer and crankshaft while using j 23523-f to push the balancer onto the shaft. After installing the j 23523-f plate and bolts with a torque of 25 nm (18 ft. Lbs.) put in the j 23523-f forcing screw, bearing, washer, and nut before turning the nut clockwise until the balancer hub meets the crankshaft position sensor reluctor ring. Place the j 23523-f aside before installing the Crankshaft Pulley followed by its bolts. Begin by lightly tightening the bolts then finish tightening them to 58 nm (43 ft. Lbs.). Position the crankshaft balancer washer crown toward the opposite direction of the engine then add the washer and bolt along with torqueing the bolt to 95 nm (70 ft. Lbs.). Afterwards, restore the cooling fan and Drive Belt.
