Illustration 1 g00477479
Use Tooling (A) in order to remove the crankshaft rear seal.
Illustration 2 g00477501
Install Tooling (B), as shown.
Care should be taken to ensure that the seal distorter does not cut through the wear sleeve. Damage to the crankshaft surface may occur leading to possible oil seal leaks.
Install Tooling (B) between Tooling (C) and the wear sleeve. Turn Tooling (B) with a wrench, until the edge of the tool makes a flat crease in the wear sleeve. Repeat this process until there are enough creases in the wear sleeve in order to allow the wear sleeve to be slipped off the end of the crankshaft.
Remove Tooling (B) and (C) and the wear sleeve by hand.
