1. Adjust forcing screw (A) on JDG698 Seal and Wear
Sleeve Remover and position screw so it centers tool
on crankshaft flange.

IMPORTANT: Holes must be drilled at outer edge of
seal case. Screws will pull seal against
wear ring, thereby removing both
pieces.
3. Drill a 3/16 in. hole through wear sleeve lip and seal
casing at the three marked locations.
4. Position JDG698 Remover on end of crankshaft.

with washers (B) into slots of removal tool and thread
screws into holes in seal casing. Evenly tighten screws
until plate is flush with rear face of crankshaft.

the three screws) until seal and wear sleeve assembly
is removed from engine.
