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.
Replacement bearings
Replacement bearings must be the same as, or equivalent to, those listed in this table.
NOTICE:
Thrust bearings must have machined bronze cages (retainers).
