Symptom

Cause

Remedy

There is excessive shaft end play.

The internal clearance of the bearings
exceeds the recommended amount.

Replace the bearings with a
bearing of the correct type.

The snap ring is loose in the bearing-
housing groove.

Re-seat the snap ring.

There is excessive shaft and sleeve
runout.

The sleeve is worn.

Replace the sleeve.

The shaft is bent.

Replace the shaft.

There is excessive bearing-frame
flange runout.

The shaft is bent.

Replace the shaft.

The flange of the bearing frame is dis-
torted.

Replace the bearing-frame
flange.

There is excessive frame-adapter run-
out.

There is corrosion on the frame
adapter.

Replace the frame adapter.

The adapter-to-frame gasket is not
seated properly.

Re-seat the frame adapter and
make sure that the adapter-to-
frame gasket is seated properly.

There is excessive seal chamber or
stuffing-box cover runout.

The seal chamber or the stuffing-box
cover is not properly seated in the
frame adapter.

Re-seat the seal chamber or
stuffing-box cover.

There is corrosion or wear on the seal
chamber or stuffing-box cover.

Replace the seal chamber or
stuffing-box cover.

There is excessive vane-tip runout of
the impeller.

The vane is bent.

Replace the impeller.
