Rear Oil Seal
a. Coat the lip of the oil
seal (5) lightly with
engine oil (single lip
seal) or vegetable
shortening (double-lip
seal). Do not scratch or
nick the sealing edge of
the oil seal.
b. Drive the seal into the
housing with installer
J9727 and handle until it
is seated against the
seal spacer (if used) or
on shoulder in the
housing bore. The
installer prevents damage
to the seal by exerting
force only on the outer
edge of the seal casing.
If it is necessary
to install the oil seal
with the flywheel housing
on the engine, place
oil seal expander against
end of crankshaft. Then,
with the lip of the seal
pointed toward the
engine, slide the seal
over the tool and onto
the crankshaft. Remove
the seal expander and
drive the seal in place
with installer J9727 and
handle.
c.
Remove any excess sealant
from the flywheel housing
and the seal.
