• Q: How to replace the front harmonic balancer on 2008 Chevrolet Silverado 1500?

  A: Starting the crankshaft balancer replacement requires Drive Belt and cooling fan removal. A shorter bolt with matching threads to those of the crankshaft balancer bolt should be installed to protect the crankshaft before using the crankshaft balancer removal tool. Start the process by uninstalling both the crankshaft balancer bolt along with its washer then move to disassemble the crankshaft pulley bolts and pulley. A technician should employ the crankshaft balancer remover and installer (J 23523-F) to eliminate the crankshaft balancer. Put the j 23523-f plate along with bolts onto the crankshaft balancer before torquing them to 25 n.m (18 lb ft) while inserting the forcing screw and rotating it clockwise for balancer removal. Safety checks should be performed on the crankshaft balancer together with a visual inspection to confirm its weights have the original length and position. Lubricate the crankshaft front cover seal with grease when using it again and verify the correct position of the balancer weights. Start by applying adhesive into the crankshaft balancer keyway next to the crankshaft key before pressing the balancer onto the crankshaft with j 23523-f. Afterward mount the j 23523-f plate with its bolts onto the front of the balancer. Tighten these front bolts to 25 n.m (18 lb ft) then put in a forcing screw followed by the bearing and washer. Finish by turning the nut clockwise while letting the balancer hub rest against the crankshaft position sensor reluctor ring. Loosen the j 23523-f then attach the crankshaft pulley using its bolts which need light tightening first before achieving 58 n.m (43 lb ft) torque. Fit the crankshaft balancer washer crown in the direction opposite to the engine before installing the washer and bolt which must be tightened to 95 n.m (70 lb ft). Close the procedure by installing the Drive Belt along with the cooling fan.
