Mopar 4667198 Crank Seal

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, modular clutch assembly (if equipped), and driveplate. It is important to ensure that the Crankshaft Seal is installed flush with the outer surface of the block. Pry out the old seal using a 3/16-inch flat blade screwdriver, taking care not to scratch or damage the crankshaft sealing surface or the seal bore in the engine block to prevent an oil leak. Clean the crankshaft and seal bore thoroughly, degreasing the areas with a rag soaked in lacquer thinner or acetone, and do not lubricate the lip or outer diameter of the new seal; it must be installed dry as it comes from the manufacturer. Position the new seal onto the crankshaft, ensuring that if marked, the words THIS SIDE OUT on the seal face outward, 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; if driven in past flush, an oil leak will occur, so check that the seal is indeed flush. The remaining installation steps follow the reverse order of removal.
