Buick 10101369 Crankshaft Balancer Assembly

Remove the cable from the negative battery terminal, then loosen the accessory drivebelt tension adjusting bolts and remove the drivebelts, tagging each belt for easier reinstallation. Jack up the vehicle and secure it on jackstands before removing the right rear wheel. Take out the right rear inner fender splash shield by pulling out the plastic pop fasteners, as this is necessary to access the crankshaft pulley. If equipped with a manual transaxle, apply the parking brake and put the transaxle in gear to prevent the engine from turning over, then remove the crank pulley bolts. For vehicles with an automatic transaxle, remove the starter motor and immobilize the starter ring gear with a large screwdriver. A breaker bar may be needed due to the tightness of the bolts. To loosen the crankshaft hub retaining bolt, thread a bolt into one of the pulley bolt holes, place a large breaker bar and socket on the retaining bolt, immobilize the hub with a large screwdriver, and then remove the bolt. Remove the crank hub, using a puller if necessary, and carefully pry the oil seal out of the front cover with a large screwdriver, taking care not to damage the cover. Install the new seal with the lip toward the engine, driving it into place with a seal installation tool or a large socket. Apply a thin layer of multi-purpose grease to the seal contact surface of the hub, position the pulley hub on the crankshaft nose, and ensure it aligns with the Woodruff key. Use the crankshaft hub bolt to press the hub into position and tighten it to the specified torque. Install the crank pulley on the hub, applying thread locking compound to the pulley-to-hub bolts before installation, and finally reinstall the drivebelts and the right rear inner fender splash shield.
