Spicer strongly recommends using seal drivers when installing
new seals. Use the proper driver to make sure that the seal is
square and installed to the proper depth.
Oil seals can be easily damaged prior to installation.
Use care when handling the new seal to prevent damage
or contamination. Leave the seal in its package until
installation. On new yokes, leave the protector on the
yoke until it is installed on the shaft to prevent damage
or contamination.
1. Remove the old yoke using appropriate tool. A yoke
puller tool may be made from the center section of
most gear puller tools, or may be purchased from
your local tool distributor.
2. Remove seal. Use care when removing the old seal
to prevent damage to the housing seal bore .
3. Inspect the seal bore area for any damage (nicks,
gouges, corrosion). Carefully remove any slight
damage with a crocus cloth. Clean the bore area to
remove any loose debris .
Do not use any silicone or permatex-type bore sealant with
this seal.
4. Remove the new seal from its package and install
with the proper driver :
R - Pinion Driver - 210749
R - Pinion Insert - 131472
Due to the resiliency of the plastic driver, hammer rebound
may occur when the seal is seated. Keep clear of the ham-
mer rebound path!
5. Handle the seal by its outside diameter avoiding any
contact with the seal lips. During installation, use the
proper driver to make sure that the seal is mounted
properly.
6. Use a rubber mallet to drive the seal tool in until the
flange bottoms on the housing cover bore face. The
flange will locate the seal at the proper depth.
