Bearing-frame inspection
Checklist
Check the bearing frame for these conditions:
• Visually inspect the bearing frame and frame foot for cracks.
• Check the inside surfaces of the frame for rust, scale, or debris. Remove all loose and
foreign material.
• Make sure that all lubrication passages are clear.
• If the frame has been exposed to pumped fluid, inspect the frame for corrosion or pitting.
• Inspect the inboard-bearing bores.
If any bores are outside the measurements in the Bearing fits and tolerances table, replace
the bearing frame.
