Front Oil Seal
Illustration 43
Installation of the front oil seal and wear sleeve for the crankshaft
(1) Crankshaft pulley
(2) Front oil seal
(3) Hub of crankshaft pulley
(4) Wear sleeve
(5) Face front oil seal housing
(A) Depth of front oil seal
The front oil seal (2) is normally installed to a depth of 7.00
0.25 mm (0.2756 0.0098 inch) (A) from the face of the front
oil seal housing (5). The oil seal may cause wear on the hub
of the crankshaft pulley (3). This wear may allow oil leakage
past the oil seal. If this situation occurs, the front oil seal can
be installed to a depth of 9.3 mm (0.37 inch) from the face of
the front oil seal housing.
If a wear sleeve (4) is installed, the front oil seal is installed to a
depth of 9.30 mm (0.366 inch) from the face of the front oil seal
housing. When the wear sleeve is installed, the flange of the
wear sleeve does not require removal. If a wear sleeve is
installed, a new front oil seal must be installed.
