Tools Required

1. Drain the engine coolant from the cooling system. Refer to Cooling System Draining and Filling in Engine Cooling.
2. Remove the engine oil pan. Refer to Oil Pan Replacement .
3. Remove the engine flywheel. Refer to Engine Flywheel Replacement .



4. Remove the crankshaft rear oil seal housing bolts.
5. Remove the crankshaft rear oil seal housing.

Important: Make sure not to damage the crankshaft OD surface with any tool.

6. Remove the gasket from the crankshaft rear oil seal housing and the cylinder block.



7. Place the crankshaft rear oil seal housing face down on a clean surface and support with blocks of wood.
8. Use a suitable driving tool and hammer and lightly tap around the outer edge of the seal to remove it.
9. Clean and inspect the crankshaft rear oil seal housing making sure it is free of any foreign material.
10. With all bolts removed from the housing, place it face up on a flat clean surface.

Notice: Do not apply or use any oil lubrication on the crankshaft rear oil seal, or the seal installer. Do not touch the sealing lip of the oil seal once the protective sleeve is removed. Doing so will damage/deform the seal.

Notice: Clean the crankshaft sealing surface with a clean, lint free towel. Inspect lead-in edge of crankshaft for burrs/sharp edges that could damage the rear main oil seal. Remove burrs/sharp edges with crocus cloth before proceeding.

1. Carefully remove protection sleeve from the new rear oil seal assembly.

Important: Notice the direction of the rear oil seal. The new design seal is a reverse style as opposed to what has been used in the past. "THIS SIDE OUT" has been stamped into the seal as shown in the graphic.

2. Install the seal onto the EN-47623 by placing the seal on an angle and using a twisting motion until it is fully seated.



3. Using the EN-47623 and J 8092 , install the rear main crankshaft oil seal into the housing using constant downward force until the seal is fully seated.



4. Clean the crankshaft sealing surface with a clean, lint free towel. Inspect the crankshaft sealing surface and leading edge of the crankshaft for burrs/sharp edges that could damage the rear main oil seal. Remove any burrs or sharp edges with crocus cloth before proceeding.

Notice: Do not use a sealant or adhesive when installing this component. Use of a sealant or adhesive can cause improper sealing. A component that is not sealed properly can leak leading to extensive engine damage.

Important: Always install a new crankshaft rear oil seal housing gasket.

5. Install a new crankshaft rear oil seal housing gasket and the housing onto the engine.

Important: The plastic inserts found on the rear oil seal housing retaining bolts are used to aid in production assembly only. The inserts are not required for service.

6. Install the crankshaft rear oil seal housing bolts and finger tighten.




Notice: Correct alignment of the housing is crucial to sealing ability of the rear main and the oil pan. Take care when installing the housing to ensure that the housing is properly aligned. Failure to follow these procedures may result in oil leaks.

7. Place a straight edge on the engine block oil pan flange and the crankshaft rear oil seal housing flange. Use a feeler gage to ensure that there is no more than a 0.10 mm (0.004 in) step on each side. If necessary, gently rotate the crankshaft rear oil seal housing to make the step equal on each side.

Notice: Refer to Fastener Notice in the Preface section.

8. Tighten the crankshaft rear oil seal housing bolts.

Tighten
Tighten the crankshaft rear oil seal housing bolts to 15 N·m (11 lb ft). Use the J 45059 to tighten the bolts an additional 50 degrees.

9. Recheck the step height on each side to ensure that the crankshaft rear oil seal housing did not move. If the step height is beyond specification, reinstall the crankshaft rear oil seal housing and measure the step again. Replace the crankshaft rear oil seal housing if the clearance is still beyond specification.
10. Install the engine flywheel. Refer to Engine Flywheel Replacement .
11. Install the engine oil pan. Refer to Oil Pan Replacement .
12. Fill the cooling system with engine coolant. Refer to Cooling System Draining and Filling in Engine Cooling.
