The one-piece rear Crankshaft Seal is pressed into a bore machined into the rear main bearing cap and engine block. Begin by removing the transaxle, the clutch components if equipped, and the
Flywheel or driveplate. The oil seal is installed flush with the outer surface of the block, so pry out the old seal with a 3/16-inch flat blade screwdriver. To prevent an oil leak after the new seal is installed, be very careful not to scratch or otherwise damage the crankshaft sealing surface or the bore in the engine block. Clean the crankshaft and seal bore in the block thoroughly and degrease these areas by wiping them with a rag soaked in lacquer thinner or acetone. Position the new seal onto the crankshaft, ensuring that if marked, the words THIS SIDE OUT on the seal face out, toward the rear of the engine. Using an appropriate size driver and pilot tool, drive the seal into the cylinder block until it is flush with the outer surface; driving it in past flush may result in an oil leak. The remainder of installation follows the reverse order of removal.
