15 TIMING CASE AND DRIVE ASSEMBLY
Front oil seal
To remove and to fit15A-02
A special front oil seal is used in engines where
immersion of the seal in water is possible. The
water immersion seal has a flexible front lip that
protrudes onto the boss of the front pulley. This
front lip prevents the leakage of water past the oil
seal. As the front lip on this type of oil seal is very
flexible, the oil seal must be kept on the plastic
mandrel (A1) supplied with it until the seal is to be
fitted. The plastic mandrel must be fitted to the seal
immediately the crankshaft pulley is removed. This
will ensure that the front lip of the seal will keep its
correct shape.
To remove
1Remove the fan, operation 21A-04 and the drive
belts, operation 23A-03.
2Remove the crankshaft pulley, operation 14A-01.
3 Remove the oil seal with a suitable lever behind
the main lip of the oil seal. Do not damage the edge
of the oil seal housing.
To fit
Special tools:
Replacer tool for front oil seal (main tool), PD170
Pressure plate for use with PD.170, PD170-1
Sleeve for use with PD.170, PD170-2

The standard seal is fitted to a depth of
6,75/7,25 mm (0.266/0.285 in) from the front face
of the oil seal housing to the flat front face of the oil
seal. If, in service, there is wear in the seal location
area of the crankshaft pulley, the oil seal can be
