Maintenance
4. Install and then hand-tighten the casing bolts (370).
Refer to the bolt torque values for information on how to tighten the casing bolts.
5. Install and tighten the casing jackscrews (418).
NOTICE:Do not overtighten the casing jackscrews. Doing so may result in equipment
damage.
6. Reinstall the shims under the frame foot and tighten the frame foot to the baseplate.
Make sure that you use the proper shim. Mount a dial indicator in order to measure the
distance between the top of the frame and the baseplate. Make sure that the distance does
not change as you tighten the frame-foot bolts.
7. Check the total clearance of the impeller in the casing.
With new parts, an acceptable range is 0.030 in. (0.76 mm) to 0.065 in. (1.65 mm). If the
impeller clearance is outside of this range, you either have the incorrect parts, an improper
installation, or too much pipe strain. Determine the cause and correct the problem before
you proceed.
8. Adjust the impeller clearance.
Refer to the Impeller clearance setting section for more information.
9. Replace the auxiliary piping.
10. Fill the pump with the proper lubricant. See Lubricating-oil requirements.
11. Reinstall the coupling guard.
