CAUTION:

The seal lip and the sealing surface on the crankshaft must be free of all oil residue, to prevent leaks. The crankshaft and seal surface must be completely dry when the seal is installed.

  1. Clean the cover and the gear housing gasket mating surfaces and use caution not to damage the surface. Ensure these surfaces are clean of prior sealant material and do not sand these mating surfaces as this will cause potential leaks. Ensure the front crankshaft seal lip and the crankshaft mating surfaces are free from all oil residue to prevent seal leaks.
  2. Inspect the gear housing and front cover for damage or cracks and replace if necessary. Inspect the crankshaft mating surface for any grooves or nicks that would affect the integrity of the new seal. Ensure the surface is free of debris before installing the crankshaft seal.
  3. Apply a bead of Mopar® Stud AND Bearing Mount to the outside diameter of the seal. Do not lubricate the inside diameter of the new seal.
  4. With the engine timing cover supported by wood blocks, install the seal (2) into the rear of the cover using the (special tool #10136, Installer, Crankshaft Front Oil Seal) (1) and (special tool #C-4171, Driver Handle, Universal) (2). Strike the driver handle until the installation tool bottoms out on the inside of the engine timing cover. Ensure the front cover is not damaged from installation of the seal during repair.
