6. Slide the spacer ring and inner bearing spacer into the spindle housing, then
install the upper bearing cone and oil seal into the top of the housing.
Note: The upper seal must have the lip facing in (down). Also, install upper
seal so it is flush to 1.5 mm (0.060 inch) recessed to the housing surface
(Figure 301).
7. Examine the spindle shaft and shaft spacer to ensure that there are no burrs
or nicks that could damage the oil seals. Lubricate the shaft and spacer
with grease.
8. Install the spindle shaft spacer onto the shaft. Place a thin sleeve or tape on
the spindle shaft splines to prevent damage of the seal during the installation
of the shaft.
9. Carefully slide the spindle shaft with the spacer up through the spindle
housing.
Note: The bottom oil seal and spindle spacer fit together when the spindle
is fully installed.

A pneumatic grease gun can produce high pressure inside the
spindle housing that can damage the spindle seals. Thus, do not use
a pneumatic grease gun for greasing of the spindle housings.
12. Attach a hand pump grease gun to the grease fitting on the housing and fill
the housing cavity with grease until the grease starts to come out of the
lower seal.
