1 Remove the seals from the housing with a
suitable lever. Ensure that the seal housing is not
damaged. Do not try to press the seals out of the
housing as there is a shoulder in the housing (A).
2 Clean thoroughly the oil seal housing. Inspect the
oil seals for damage. If only a small scratch can be
seen across the lip of the seal, do not fit the seal.
3 Before the oil seals are fitted into the housing
ensure that the correct seal is fitted to the correct
side of the housing. Each of the seals has an arrow
(A2) and (A3) on the flat face of the seal. This
arrow indicates the correct direction of shaft
rotation for the seal.
4 Lubricate lightly the outer circumference of the
front oil seal and the bore of the housing for the
front seal with clean engine oil.
5 With the flywheel side of the seal housing on a
suitable support, press the new front seal into the
housing. Use a suitable tool which will apply
pressure only to the flat inside face of the seal. Use
only enough pressure to ensure that the flat face of
the seal is against the shoulder in the housing. Too
much pressure could damage the shoulder.
6 Lubricate lightly the outer circumference of the
rear oil seal and the bore of the housing with clean
engine oil.
7 With the engine side of the seal housing on a
suitable support, carefully press the rear oil seal
onto the shoulder in the housing with the same tool
as for the front seal. Ensure that the seal is against
the shoulder in the housing.
Caution: The rear oil seal must not be fitted if the
engine is to be operated before the oil is added to
the flywheel housing. The seal must be fitted to the
seal housing after the engine has been run.
