2002 Buick LeSabre Flywheel Parts and Q&A

• Q: How to service and repair the engine flywheel on 2002 Buick LeSabre?

  A: Start service and repairs of the engine Flywheel by first removing the transaxle then removing eight bolts that attach the Flywheel to the Crankshaft flange where you should dispose of these bolts. The assessement of Crankshaft mating surfaces for burrs leads to cleaning the engine Flywheel followed by inspection. The installation process begins with properly positioning the Flywheel before bolting its replacement parts with 15 nm torque (11 ft. Lbs.) and extending the bolt torque with the torque angle meter (J 36660-A) by an additional 50 degrees. Use the dial indicator set (J 8001) to check runout at the three attaching bosses on the engine block while keeping the Crankshaft end-play in one direction; the acceptable Flywheel runout range is 0.381 mm (0.015 inch). You need to replace the Flywheel if correcting its runout exceeds specification and you cannot fix it by tapping the higher side with a mallet. Finally, reinstall the transaxle.
