compound in the bore before pressing in the
If new seal is pre-coated, sealing
compound is not required.
Cement a new
gasket (10) to the bellhousing (9), allowing the
cement to dry sufficiently to prevent the gasket
from slipping at installation.
(2) Clean and polish the oil seal surface of the
crankshaft to remove nicks or scratches. Use
crocus cloth or very fine polishing cloth.
(3) Apply a thin coat of oil soap to the seal and the
seal surface of the crankshaft. If seal is already
oil treated, additional lubricant is not required;
however, take care to keep the seal surface
clean during reassembly. Make sure that the
top rear cam thrust plate attaching screw hole is
plugged with a setscrew. This hole runs into an
oil hole in the block.
Carefully place the
bellhousing (9) on the cylinder block so that the
seal is not damaged as it engages the
crankshaft. Align so that the dowels properly
enter their respective holes.

be installed in one position. This ensures proper
location of the flywheel on the crankshaft for
timing purposes. Draw the flywheel onto the
