Maintenance
Install the back pull-out assembly in the casing
1. Install a new casing gasket on the gasket surface of the casing.
You can apply anti-galling compound to the casing fits to aid in assembly and disassembly.
2. Replace the back pull-out assembly in the casing using a lifting sling through the bearing
frame or other suitable means.
3. Slide the back pull-out assembly into the proper position in the casing by loosening the
jacking bolts evenly.
Make sure that the casing gasket is not damaged.
4. Install the casing stud nuts.
5. Inspect the gap between the seal-chamber cover and casing and adjust the casing stud
nuts as necessary to make the gap uniform.
6. Tighten the casing stud nuts uniformly, using an alternating pattern, until the seal-chamber
cover is in metal-to-metal contact with the casing. Tighten each nut to the torque values
shown in the Maximum torque values for 3700 fasteners table.
7. Verify that the shaft turns freely.
If you detect any rubbing or excessive drag, then determine the cause and correct it.
8. Reinstall the coupling spacer, coupling guard, auxiliary piping, tubing, and equipment that
was removed during preparation for disassembly.
9. Lubricate the bearings.
