Cutting Units: Service and Repairs
If you are replacing the bearings, ensure that you use the spacer ring
that is included with a new bearing set; refer to
7. 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.
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; refer
to Figure 52.
8. 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.
9. 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 and 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.
