NEVER PRESS OR HIT AGAINST THE OUTER RACE, BALLS, OR BALL CAGE DURING
BEARING INSTALLATION ONTO THE SHAFT. PRESS THE INNER RACE ONLY.
Use the bearing snap ring to attach the outboard bearing on the shaft.
Weir Specialty Pumps recommends the use of a WSP shaft installation tool or a
properly tapered sleeve if the WSP shaft tool in unavailable. This will prevent the lip
of the oil seal from rolling as the shaft and bearings are installed in the bearing
housing.
When the lip seal sleeve is installed, lubricate the lip seal portion of the shaft before
sliding the shaft and assembled bearings into the bearing housing. The retaining ring
on the outboard bearing should be seated against the bearing housing. Next,
remove the installation tool or properly tapered sleeve.
Once the lip is positioned as shown in Figure 7, push the inboard oil seal into the
bearing housing bore.
Now, push the outboard oil seal into the bearing cap while the lip is positioned as
noted in Figure 7. Replace the bearing cap gasket and attach the bearing cap with
its hardware. Take care not to damage the oil seal lip on the shaft keyway.
Figure 7
Follow instructions in Section VI. LUBRICATION, to lubricate the bearing housing
correctly.
