2.
Insert bearing housing and shaft assembly into frame (228).
3.
Reassemble column pipe (192), frame (228), discharge pipe (195), casing (100), discharge elbow
(315), and throttle bushing (473) as required.
4.
Position bearing housing shaft assembly so that the shaft is as far into the water end as possible.
This will assure proper placement of the impeller (101) on the shaft.
5.
Install nuts on bearing housing locking studs (370C).
6.
Slide shaft sleeve (126) onto shaft after coating shaft with an anti-seizing compound such as "Never
Seez" or equal.
7.
Remove protective tape from shaft threads.
8.
Thread impeller (101) onto shaft (122). Make sure impeller contacts shaft sleeve (126).
9.
Rotate shaft to assure that all parts are free.
10. Move impeller (101) by means of the impeller adjusting bolts toward the throttle bushing (473) as far
as possible.
11. Attach suction liner (1008) to the suction cover (182). Apply a small amount of "Never Seez" in cas-
ing fit to facilitate removal.
12. Place o-ring on suction cover (182). Position suction cover and suction liner assembly into casing
(100) and bolt it in place. Tighten all bolts evenly so that suction cover will not become misaligned.
13. Adjust impeller (101) using the adjusting bolts so that it rubs the suction liner (1008). Back off impel-
ler approximately .06in., the recommended operating clearance. Do not cock the bearing housing
(134A). Make sure the impeller turns freely through the entire rotation. Lock adjusting bolts in place.
14. Tighten bearing housing locking studs (370C).
15. Attach motor mount if direct connected pump.
16. Connect v-belt drive or coupling.
17. Follow procedure for installation of vertical pumps.
