6 APPENDIX A - IMPELLER CLEARANCE SETTING
If a gradual loss in head and/or capacity occurs, you can restore performance by
adjusting the impeller clearance, which is the measurement between the impeller vanes
and the surface of the casing.
Table 6
displays the suggested impeller clearance
settings based on the temperature of the liquid.

6.1 FEELER GAUGE TECHNIQUE

Lock out driver power before beginning
work on pump
TO USE THE FEELER GAUGE TECHNIQUE FOR IMPELLER CLEARANCE SETTING
1. Lock out power to the pump driver.
2. Remove the coupling guard.
3. Loosen jacking bolts (370D) and jam nuts (423).
4. Tighten bearing housing bolts (370C) evenly, while slowly rotating the shaft until the
impeller starts to rub on the casing.
5. Using a feeler gauge, set the gap between the 3
housing bolts (370C) and the bearing housing
(134). (Refer to Table 6 for settings.)
6. Tighten jack bolts (370D) evenly until bearing
housing backs out and contacts the bearing
housing bolts (370C).
7. Tighten jam nuts (423) evenly, rotating the shaft to
make sure the assembly turns freely.
8. Reinstall the coupling guard.
9. Unlock power to the pump driver.
