1. Clean the pulley (3) and clean the thrust block
(2). Inspect the pulley (3) and the thrust block (2)
for wear and for damage. If necessary, replace
any damaged component. Inspect the area on
the pulley that is normally in contact with the
crankshaft front seal. If there is excessive wear
then a wear sleeve can be installed. Refer to the
Disassembly and Assembly Manual, "Crankshaft
