  Q: How to replace the harmonic balancer on Buick Enclave?

  A:

  Replace the crankshaft balancer by starting with the removal of the engine mount strut bracket followed by the Drive Belt and Starter. The en 46106 (Flywheel Holding Tool) must be installed through the Starter hole while right frame side support comes from jackstands. The right side frame reinforcement bolts must be taken out while right side frame bolts are loosened to drop the right side frame approximately 2 inches. First use the j 38416-2 (Crankshaft Button) to insert into the crankshaft nose then apply the j 41816 (Crankshaft Balancer Remover) for removing the crankshaft balancer from the crankshaft. Installation of en 46106 to flywheel occurs as a part of the process. Use the j 41998-b (Crankshaft Balancer Installer) while inserting a nut and bearing and washer to install the crankshaft balancer by neglecting lubricant application on the front oil seal and balancer sealing surfaces of the crankshaft. Place the balancer on the crankshaft while lubricating its hub bore with the j 41998-b tool installed before the tool reaches 10 threads in the crankshaft. ((J 41998-B)) nut should be tightened until the large washer rests against the crankshaft end before (.J 41998-B') removal allows for (J 45059) installation of the crankshaft balancer bolt which needs to be threaded to 100 nm (74 lb ft) and further tightened for 150 degrees. The final step involves Starter reinstallation followed by use of an engine support fixture to raise the engine. Additionally, the engineer must install the engine mount strut bracket together with the Drive Belt.
