INSTALL CRANKSHAFT REAR OIL SEAL
AND WEAR SLEEVE (WITHOUT ENGINE
DISASSEMBLY)
NOTE: These instructions are for use when the oil seal
housing and oil pan would not be removed. Refer
to INSTALL CRANKSHAFT REAR OIL SEAL
AND WEAR SLEEVE (WITH ENGINE
DISASSEMBLED), later in this group, for
instructions with oil seal housing and oil pan
removed.
Installing Crankshaft Rear Oil Seal/Wear Sleeve
1. Apply a light coating of LOCTITE 609 Retaining
Compound, or equivalent, completely around the
leading edge of crankshaft flange. Wipe away any
sealant that may have gotten on I.D. of seal housing
bore.
2. Install JDG477 (85) Pilot (A) on end of crankshaft
using the Allen head cap screws (B) supplied with tool
set. Tighten cap screws securely.
IMPORTANT: Handle seal and wear sleeve assembly
carefully. If assembly becomes
separated, discard these parts and
install a new assembly. (See
CRANKSHAFT REAR OIL SEAL AND
WEAR SLEEVE HANDLING
PRECAUTIONS, later in this group.)
When installing the JDG478 Driver on
JDG477 (85) Pilot and crankshaft flange
to position oil seal/wear sleeve
assembly, locate crossbar of installer at
right angle (90) to Allen head cap
screws. This allows the crossbar to
bottom on pilot, not head of cap
screws, assuring correct installation.
3. Carefully start oil seal/wear sleeve assembly (C) over
JDG477 (85) Pilot and crankshaft with open side of
seal toward engine.
