2005 Buick LeSabre Parts Questions & Experts Answers

• Q: What tools are required to service and repair the flex plate and replace the engine flywheel on 2005 Buick LeSabre?

  A: Service and repair of the flex plate and engine Flywheel replacement requires the tools j 8001 dial indicator set (J 8001) and j 45059 torque angle meter (J 45059). Circumferential blades must be installed onto the Crankshaft before removing the transaxle and removing the 8 bolts which connect the Flywheel to the Crankshaft flange and discarding the bolts. You need to check the Crankshaft mating surfaces for burrs after the Flywheel removal. Perform cleaning examination on the engine Flywheel before performing its installation. During Flywheel installation the user should first tighten new bolts to a torque of 15 nm (11 ft. Lbs.) using j 45059 to proceed with an additional 50-degree bolt-tightening procedure. Use the j 8001 tool to check the Flywheel runout at the three attaching bosses while maintaining the Crankshaft end-play in one direction until measurements reach 0.381 mm (0.015 inch). A mallet should be used for tapping the high side to adjust runout till specifications are met and Flywheel replacement becomes necessary when runout cannot be adjusted. Finally, reinstall the transaxle.
