INTRODUCTION
Seal installation procedure (with lip facing outwards)
It is essential to use a tool (3) which supports the seal by
its rigid base, without causing deformation or damage to
the sealing lip.
Move the seal until the rigid face reaches the bottom of
the housing, but without forcing it.
Observations:
• The displacement of the seal into the housing must be
in an aligned manner. Therefore, it is important that the
tool
(3) has an extension that facilitates the alignment.
• Before installing a seal, make sure that the housing is
clean and dry, free of grease or oil.
• After installing the seal, grease the seal lip.
• Take care when mounting the shaft that goes through
the seal, especially spline shafts with key slot and an-
other type of edge that can damage the retainer lip.
• Tiny cuts on the lip cause leaks.

INSTALLATION OF SEALS IN HUBS WITHOUT GREASE FITTING
In these cases, the replacement is performed with the dis-
assembly of the hub.
This way, the seal does not have the function of allowing
the outflow of excess grease. Therefore, it is installed with
the lip facing inward (and the flat face outwards).
To install it with the lip inwards:
• See the remarks of the previous item (seal with lip fac-
ing outwards).
• Lay the tool
(4) on the rigid (flat) face of the seal (2)
• Typically, the depth of the seal installation must be such
that the flat face is aligned with the outer surface (5) of
the hub.

REPLACEMENT OR REUSE OF BEARINGS
To decide on the reuse of bearings, the first step is to
perform a thorough cleaning
(1) .
In step (2) analyze the bearing for damage such as
signs of overheating (bluish surfaces), wear, scratches or
breaks in its rollers or balls, and the surface of the tracks
and other damage.
