11. Fill the remainder of the baseplate with grout and allow the grout to set for at least 48
hours.
12. Remove the leveling jackscrews after the grout hardens in order to remove any stress
points.
13. Tighten the foundation bolts.
14. Recheck the alignment.
Perform a final “soft foot” check
A final check for soft foot should be made after completion of coupling alignment and grouting.
A soft foot condition may result in body stresses that may result in shortened bearing life. Soft
foot may be checked as follows:
1. Attach the base of a dial indicator to the base plate, placing the tip of the indicator one of the
pump’s feet.
2. Adjust the indicator to read zero.
3. Loosen the hold down bolt at the foot on which the indicator is reading.
4. If the indicator shows movement of greater than 0.05mm (0.002in) the foot is said to be
“soft”.
5. Shim under the soft foot to reduce the indicator travel to less than 0.05mm (0.002in). If multiple
shims are already in place, the use of fewer, thicker shims will reduce the tendency of soft foot
to occur.
6. Repeat this process until all of the pump feet have been checked and corrected for a soft foot
condition.
If a dial indicator is not available, feeler gauges may be used
