®
SEAL
(WET-TYPE FLYWHEEL HOUSING)
The oversize inside diameter lip seal and wear
ring are shipped as an assembly, with the seal
installed on the wear ring. Do not remove the seal
from the wear ring prior to installation. The wear
ring and seal installer J 35529 is required for
installation. This tool presses both the wear ring
and the oil seal onto the crankshaft flange.
SPECIAL TOOL REQUIRED
r
Wear Ring and Seal Installer J 35529
Refer to Figure 255.
1. Remove existing wear ring from crankshaft
before installing new wear ring.
2. Thoroughly clean and dry the crankshaft
flange.
3. Apply a thin, even layer of Loctite
®
609 to
the circumference of the crankshaft flange.
Do not lubricate the lips of a Teflon

seal before
installation. Teflon

seals function most
effectively when installed dry.
4. The lip of one side of the seal is yellow.
Install the oil seal with the yellow lip toward
the transmission. Position the oil seal and
wear ring assembly onto the recessed side
of the installation tool adapter plate with the
yellow lip facing away from the direction of
installation (toward the transmission).
5. Using the three guide pins, attach the oil
seal installation tool adapter plate to the
crankshaft flange.
6. Install the press cup over the guide pins.
Then install the press cup driver hex nut.
7. Tighten the hex nut until a positive stop is
felt. At that point, the oil seal and wear ring
are properly installed on the crankshaft
flange. The double-lip seal is properly
installed to a depth of 0.250 inch
±
