Thrust Bearing Adjustment
1.
Loosen axial setscrews in face of end cap on the thrust bearing
assembly. If rotor shaft cannot be turned by hand, back off the
thrust bearing assembly until there is a noticeable drag of the shaft.
Note mechanical seal will provide some drag and this is a normal
condition. The thrust bearing assembly must be turned in until it can
just be turned over by hand. This ensures the rotor is against the
head and a zero end clearance condition exists.
2. Make a mark on the OD of the bearing housing and a corresponding
mark on the bracket. Back off thrust bearing housing the required
number of marks or distance on the OD as shown below.
3. Tighten the axial setscrews in the face of the thrust bearing
assembly. Make sure the rotor shaft turns freely. If it does not,
repeat steps 1 and 2.
*Each small notch on outer end cap represents .001 inch end clearance.
