Bearings inspection
Condition of bearings
Do not reuse bearings as this is typically a false economy. The remaining life available on a
bearing cannot be determined through simple inspection. The condition of the bearings will
provide useful information on the operating conditions seen by the bearings in the bearing
frame.
Checklist
Perform these checks when you inspect the bearings (103), (105):
•
Note the lubricant condition
– color, smell, free water and residue. For example, a burnt
aroma or cloudiness of the lubricant can indicate abnormal operation. In such cases
further oil analysis from a specialist company is recommended.
•
Inspect the bearings to see if they are loose, rough, or noisy when you rotate them. In
the case of separable bearings, inspect each component individually noting the location
and magnitude of wear.
•
Investigate any abnormal lubricant or bearing damage to determine the cause. If the
cause is not normal wear, correct the issue before you return the pump to service.
Replacement bearings
Replacement bearings (103), (105) must be the same as, or equivalent to, those listed in
these tables.
