Bearings inspection
Condition of bearings
Do not reuse bearings. The condition of the bearings provides useful information on operating conditions
in the bearing frame.
Checklist
Perform these checks when you inspect the bearings:
• Inspect the bearings for contamination and damage.
• Note any lubricant condition and residue.
• Inspect the ball bearings to see if they are loose, rough, or noisy when you rotate them.
• Investigate any bearing damage to determine the cause. If the cause is not normal wear, correct the
issue before you return the pump to service.

• Inspect the bearing-housing (134) bore according to the bearing fits and tolerances table.
