Crankshaft Rear Oil Seal

 

Removal

  1. Remove the oil pan (6675). Refer to Oil Pan/Oil Pump Screen Cover and Tube in the In-Vehicle Service portion of this section.

  1. Loosen all the crankshaft main bearing cap bolts, thereby lowering the crankshaft (6303) slightly but not to exceed 0.7938mm (1/32 inch).

  1.  CAUTION: Use care to prevent scratching or damaging the crankshaft sealing surfaces.

    Remove the rear crankshaft main bearing cap, and remove the crankshaft rear oil seal (6701) from the rear crankshaft main bearing cap and cylinder block (6010). On the cylinder block half of the crankshaft rear oil seal, use a seal removal tool, or install a small metal screw in one end of the crankshaft rear oil seal, and pull on the screw to remove the crankshaft rear oil seal.

Installation

  1. Carefully clean the seal groove in the rear crankshaft main bearing cap and cylinder block with a brush and solvent such as lacquer thinner or Metal Surface Cleaner F4AZ-19A536-RA or equivalent meeting Ford specification WSE-M5B392-A. Also, clean the area where sealer is later to be applied. Dry the area thoroughly, so that no solvent touches the crankshaft rear oil seal.

  1. Dip the split lip-type seal halves in clean engine oil.

  1.  CAUTION: Be sure no rubber has been shaved from the outside diameter of the crankshaft rear oil seal by the bottom edge of the groove. Do not allow oil to get on the sealer area.

    Carefully install the upper half of the crankshaft rear oil seal (cylinder block) into its groove with undercut side of crankshaft rear oil seal toward the FRONT of the engine (6007)(with the tab side of the crankshaft rear oil seal directed toward the rear face of the cylinder block), by rotating it on the seal journal of the crankshaft until approximately 9.525mm (3/8 inch) protrudes below the parting surface.

Allow the crankshaft rear oil seal to protrude approximately 9.525mm (3/8 inch) above the parting surface to mate with the upper half of the crankshaft rear oil seal when the rear crankshaft main bearing cap is installed.

  1. NOTE: Sealer sets up in 15 minutes.

    Apply a continuous even 1.588mm (1/16-inch) diameter bead of Gasket Maker E2AZ-19562-B or equivalent meeting Ford specification WSK-M2G348-A5 to the crankshaft rear oil seal area of the cylinder block starting from the forward face of the oil return groove and overlaying end of wire seal retainer. Do not allow sealer to contact inside diameter of the crankshaft rear oil seal.
