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.
See Install the coupling guard for more information.
NOTICE:
Risk of damage to the mechanical seal or shaft sleeve on units supplied with cartridge mechanical seals.
Prior to startup, make sure to tighten the set screws in the seal locking ring and remove the centering clips.
