Installation

1. Remove the rear crankshaft oil seal from the
flywheel housing by drilling two 3-mm holes
180 degrees apart into the outer edge of the
seal. Remove the seal with a slide hammer
fitted with a No. 10 sheet-metal screw.
Thread it into each of the holes alternately
and work the seal free.
2. Using standard shop cleaning procedures
for aluminum, clean the seal mounting
surface.
3. Insert the two dowel pins in the cylinder
block if they were removed. Refer to
