An
installation tool should always be used
when installing an oil seal. The use
of a tool can make installation easier
and lower the possibility of seal cocking.
A hydraulic or pneumatic press is advised
to supply necessary force to install
the seal.
Figure below describes examples of both
recommended and improper installation
methods. In each preferred method, installation
load is absorbed by either housing or
bottom plate to prevent seal damage
and to locate the seal properly within
the bore.
IMPROPER METHODS
PROPER METHODS
Shaft
Chamfering
Without proper chamfer on
shaft, the seal lip may be damaged or distorted
resulting in dislodged garter spring. We
suggest chamfer as below table to assist
in the installations process
