Removal
A split lip-type crankshaft rear oil seal is provided for servicing these engines.
1. Remove the oil pan and the oil pump, if required.
2. Loosen all the crankshaft main bearing cap bolts, thereby lowering the crankshaft slightly but not to exceed 0.794 mm (1/32 inch).
CAUTION: Use care to prevent scratching or damaging the crankshaft sealing surfaces.
3. Remove the rear crankshaft main bearing cap, and remove the crankshaft rear oil seal from the rear crankshaft main bearing cap and cylinder
block. 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.
4. Remove the oil seal retaining pin from the bearing cap if so equipped. The pin is not used with the split-lip seal.
