e) Inspect bearings immediately. If there is any question as to the condition of a bearing do not hesitate
to replace it. There are many conditions that contribute to the deterioration of the bearings. A qualified
bearing representative should be consulted if there is any question of bearing condition.
f) Inspected bearings which will be reused should be packed with new grease or dipped in clean
lubricating oil, covered with clean lint free rags or other suitable covering and placed in a clean box or
carton until ready for installation.
Under no circumstances the bearings are to be left exposed.
23.1.7. Labyrinths or bearing isolators (if fitted)
a) The lubricant, bearings and bearing housing seals are to be inspected for contamination and damage.
If oil bath lubrication is utilised, these provide useful information on operating conditions within the
bearing housing.
b) If bearing damage is not due to normal wear and the lubricant contains adverse contaminants, the
cause should be corrected before the pump is returned to service.
c) Labyrinth seals and bearing isolators should be inspected for damage but are normally non wearing
parts and can be re-used.
d) Bearing seals are not totally leak free devices.
Oil from these may cause staining adjacent to the bearings.
