• Q: How to replace the harmonic balancer on 2007 Chevrolet Corvette?

  A: Begin the crankshaft balancer replacement by taking out the air conditioning (A/C) drive belt along with power steering gear and Starter motor then proceed with the right transmission cover and bolt removal. Before removing the crankshaft balancer from manual transmission vehicles you must mark its position because it does not have a keyway for positioning. Follow the instructions by implementing the j 42386-a flywheel holding tool (J42386-A) with its corresponding m10 - 1.5 x 120 mm and m10 - 1.5 x 45 mm bolts. Apply 50 n.m (37 lb ft) torque until the tools start operating properly. You will reinstall the crankshaft balancer bolt (139) after its removal phase. The removability of crankshaft balancer (138) requires j 41816 crankshaft balancer remover (J41816) together with j 41816-2 crankshaft end protector (J41816-2). Keep track of the positioning of crankshaft balance weights during this procedure. Set the balancer vertically onto the crankshaft during its installation sequence. The ls2 engine already contains a thin washer. Therefore you can skip replacement. But if there is no washer you should install one (P/N 12598247). Professional installation of the balancer requires the j 41665 crankshaft balancer and sprocket installer (J41665) to guide your work. Perform the four-step tightening process initially using bolt (139) for the first stage and subsequently using a new crankshaft balancer bolt while progressively applying torque to 330 n.m (240 lb ft) and up to 50 n.m (37 lb ft) and 140 degrees using the j 45059. The final step involves eliminating j 42386-a items while reinstalling the Starter motor and power steering gear as well as the a/c Drive Belt then executing the crankshaft position (CKP) system variation learn procedure.
