Front Crankshaft Oil Seal

REMOVAL & INSTALLATION

NOTE: This procedure applies to engines with timing belts, on which the seal is located at the front of the oil pump body instead of in the engine front (timing belt) cover.

Except GLC and 1979–82 626
  1. Remove the timing belt covers, timing belt, and timing belt crankshaft pulley, as described later in this section.

  2. With a small prytool, carefully pry the seal out of the front cover. Be careful not to damage the bore of the oil pump housing with the screwdriver blade.
  3. Clean the seal bore out thoroughly. No dirt or grease should be allowed to remain inside the bore, since such foreign matter will cause premature failure of the new oil seal.

    To install:

  4. Coat the lip of the new seal with engine oil. Using a piece of pipe or a socket slightly smaller than the bore of the oil pump (and about the diameter of the seal itself), tap a new seal into place. Position the seal so its front edge is aligned with the front edge of the oil pump body.
  5. Install the timing belt crankshaft pulley, timing belt and timing belt covers in reverse order of their removal.
