2008 Chevrolet Corvette Harmonic Balancer Parts Questions & Experts Answers

• Q: How to replace the Harmonic Balancer on a 6.2L engine on 2008 Chevrolet Corvette?

  A: The crankshaft balancer replacement procedure starts with removal of the air conditioning Drive Belt and power steering gear and Starter motor. First remove the right transmission cover together with its bolt while remembering to record the initial position of the crankshaft balancer because it lacks a positioning key. Fasten the j 42386-a using one m10 - 1.5 x 120 mm and one m10 - 1.5 x 45 mm bolt then tighten them by 50 n.m (37 lb ft). The bolt numbered 139 will serve its function again for the fitting phase. Detach the crankshaft balancer (138) by using the j 41816 and j 41816-2 while recording the weight positions. Pass the j 42386-a between the crankshaft and position its straight alignment before reinstalling the two bolts while tightening to 50 n.m (37 lb ft). Place the new balancer at the identical spot where the old one used to be while adding weight if required and fitting the balancer onto the crankshaft. The installation of the balancer requires using the j 41665 to construct the threaded rod along with the nut and washer and balancer installer before tightening until the assembly completely sits. Mount used crankshaft balancer bolt (139) before tightening it to 330 n.m (240 lb ft) and then uninstalling it. The correct installation of the balancer needs to be verified by measurement before repeating the installation process. The new crankshaft balancer bolt (139) needs installation by first reaching 50 n.m (37 lb ft) torque then continuing to 140 degrees using j 45059 torque specification. Conduct the crankshaft position system variation learn procedure after installing the Starter motor along with the power steering gear and air conditioning Drive Belt while using j 42386-a for removal and reinstallation.
