How should both halves of the rear main oil seal be serviced as a unit on Buick Skylark?

Always service both halves of the rear Crankshaft Seal as a unit. While replacing this seal is much easier with the engine removed from the car, it can be done with the engine in place. Begin by removing the oil pan and oil pump, followed by the rear main bearing cap from the engine. Use a screwdriver to pry the lower half of the Crankshaft Seal from the bearing cap. For the upper half, utilize a small hammer and a brass pin punch to roll the seal around the crankshaft journal, tapping one end until the other end protrudes enough to pull it out with pliers. Clean all sealant and foreign material from the cylinder bearing cap and case without using abrasive cleaners, and inspect components for nicks, scratches, or burrs at all sealing surfaces. Coat the seal lips of the new seal with light engine oil, avoiding oil on the seal mating ends. A small plastic installation tool should be included with the purchase of the rear Crankshaft Seal. Position the narrow end of this tool between the crankshaft and the seal seat to protect the new seal from damage. Raise the new upper half of the seal into position with the seal lips facing the front of the engine, pushing it onto its seat while using the installation tool for protection. Roll the seal around the crankshaft, using the tool as a shoehorn, and once both ends of the seal are flush with the engine block, carefully remove the installation tool without withdrawing the seal. Install the lower half of the Crankshaft Seal to the bearing cap, again using the installation tool for protection, ensuring the seal is firmly seated before withdrawing the tool. Smear a bit of sealant to the bearing cap areas adjacent to the seal ends, then install the bearing cap with the seal and torque the attaching bolts to about 10 to 12 ft-lb. Tap the end of the crankshaft first rearward, then forward to align the thrust surfaces, retorque the bearing cap bolts to the proper specification, and finally install the oil pump and oil pan.

Buick Skylark Crankshaft Seal

The Crankshaft Seal in Buick Skylark cars is sitted at the front of the engine and its main function is to prevent the oil from spilling out of the crankcase. Generally made up of metal and rubber, this round seal is used mainly to ensure that lubrication is conducted to the engine hence reducing the level of friction between the parts of the engine. Different types of Crankshaft Seals may have been used at different years of production of Buick Skylark models, however, the role of Crankshaft Seal stays the same. There are indications that indicate that the Crankshaft Seal is failing, and these include, oil leakage and performance problems when the car is old. Crankshaft Seal must be checked often and changed frequently so that the Buick Skylark will have a good running engine and a long life.

Each OEM Buick Skylark Crankshaft Seal we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
