  Q: How to replace the harmonic balancer on Chevrolet Uplander?

  A: The replacement process for crankshaft balancers requires several tools including balancer and crank sprocket installer (J 29113), Flywheel holder (J 37096), crankshaft balancer remover (J 41816), as well as angle meter (J 45059). The replacement process requires removal of the Drive Belt followed by taking off right front tire and wheel together with the right engine splash shield. You need to set adjustable jack stands under the frame before you can loosen the bolts on the left side of the frame and completely remove the right side bolts to drop the right side frame for accessing the crankshaft balancer. The procedure begins by unplugging the engine to transmission bracket bolts with subsequent removal of the bracket then moving on to unscrew the torque converter cover. Affix the Flywheel holder (J 37096) to avoid Flywheel rotation before you remove the crankshaft balancer bolt together with its washer. Use the crankshaft balancer remover (J 41816) according to the procedures to remove the crankshaft balancer. Place the new crankshaft balancer on the crankshaft key after applying sealer to its keyway and secure it with the balancer and crank sprocket installer (J 29113). Use the angle meter (J 45059) to torque the new crankshaft balancer bolt first to 125 n.m (92 lb ft) then 130 degrees. Reinstall the torque converter cover before adding back the engine to transaxle bracket along with its bolts. Remove the Flywheel holder (J 37096) initially. The frame can be returned to its initial position while torqueing frame bolts to values marked on specific torque charts before the jack stands are removed and the right engine splash shield and right front tire and wheel are reinstalled, and the Drive Belt is restored.
