• Lifting eyebolt (dependent on pump size)
Drain the pump
CAUTION:
• Risk of physical injury. Allow all system and pump components to cool before handling.
• If the pumped fluid is non-conductive, drain and flush the pump with a conductive fluid
under conditions that will not allow for a spark to be released to the atmosphere.
1. Drain the pump by removing the drain plug if equipped.
Do not reinstall the plug or close the drain valve until the reassembly is complete.
2. Remove the coupling guard.
Remove the coupling
Remove the coupling in accordance with the recommendations of the coupling manufacturer.
Remove the back pull-out assembly
WARNING:
Lifting and handling heavy equipment poses a crush hazard. Use caution during lifting and
handling and wear appropriate Personal Protective Equipment (PPE, such as steel-toed shoes,
gloves, etc.) at all times. Seek assistance if necessary.
1. Is your bearing frame oil lubricated?
• If No: Proceed to step 2.
• If Yes:
1. Remove the bearing-frame drain plug (408A) in order to drain oil from the bearing
frame.
2. Replace the plug after the oil is drained.
Oil analysis should be part of a preventive maintenance program that determines the cause
of a failure. Save the oil in a clean container for inspection.
2. Place one sling from the hoist through the frame adapter (108) and a second sling from the
hoist to the bearing frame .
3. Remove the hold-down bolts of the bearing frame foot.
4. Remove the casing bolts.
WARNING:
• Risk of severe physical injury or death from explosion of trapped liquid. Never use heat to
remove parts unless explicitly stated in this manual.
5. Tighten the jackscrews evenly, using an alternating pattern, in order to remove the back
pull-out assembly.
You can use penetrating oil if the adapter to the casing joint is corroded.
6. Remove the back pull-out assembly from the casing (100).
7. Mark and remove the shims from under the frame foot and save them for reassembly.
8. Remove and discard the casing gasket.
You will insert a new casing gasket during reassembly.
9. Remove the jackscrews.
10. Clean all gasket surfaces.
Clean surfaces prevent the casing gasket from partially adhering to the casing due to
binders and adhesives in the gasket material.
