  Q: How to replace the harmonic balancer on Chevrolet Suburban 2500?

  A: A basic replacement of the crankshaft balancer requires initial removal of the air conditioning (A/C) belt and subsequent removal of the fan and Starter motor. The teeth of Flywheel holding tool (J 42847) should engage engine Flywheel teeth before installing j 42847 into Starter bolt holes and tightening bolts to 50 nm (37 ft. Lbs.). You should now remove the crankshaft balancer bolt together with washer while fitting the crankshaft balancer protector button (J 42846) at the end of the crankshaft. The Harmonic Balancer remover (J 38416-B) with j 42846 tool enables crankshaft balancer extraction by positioning its legs into the balancer inner hub recesses and tightening the center screw until the balancer clears the crankshaft nose. Take off the j 42846 when the crankshaft balancer removal is complete. Mount the balancer directly on the crankshaft end in a straight alignment while applying grease or clean engine oil to stop galling. The crankshaft balancer installer (J 42845) with lubricant must be applied to ensure proper installation of the balancer. Use the j 42845 to tighten it until complete balancer contact occurs with the crankshaft sprocket before removing the j 42845. Combine the crankshaft bolt with the washer then install it while tightening the crankshaft balancer bolt to 255 nm (189 ft. Lbs.). After removing j 42847 install the Starter motor and replace the fan and a/c belt.
