Bearings

1. Ball bearings (112A, 168A) should be inspected for

contamination and damage. The condition of the

bearings will provide useful information on

operating conditions in the bearing frame.

Lubricant condition and residue should be noted,

oil analysis is often helpful. Bearing damage

should be investigated to determine cause. If

cause is not normal wear, it should be corrected

before pump is returned to service.,

DO NOT RE-USE BEARINGS.
