Repair Procedures:
- The water jackets are chemically cleaned and hydro tested at 100 PSI to check for cracking. The water inlets and outlets are then rethreaded.
- The bearings are rebabbitted with lead-free, ASTM grade #2, high tin turbine babbitt unless otherwise specified by the customer. The methods used to rebabbitt are: Spin Casting, Pouring, Puddling, and/or TIG welding.
- The bonding of the babbitt to the bearing housing is confirmed by the ultrasonic testing of each bearing individually.
- The joints and bond lines are red-dyed. Then the joints are repaired, paralleled, and lapped to achieve an 85% blue-contact.
- Damaged dowel pins and dowel pin holes are repaired or replaced to ensure proper alignment.
- Damaged ball seats and ball fits are replaced or welded up and reground to guarantee proper fit.
- Bearing housings, carriers, rings, end bells, and end frames are repaired or remanufactured to ensure proper fit, alignment, contact, and torque.
- Finalized inspection reports are furnished to the customer with the repaired bearings.
- Bearings are boxed for long-term storage.
