12. Attach the wet end to the pedestal by installing and fully tightening the alignment stud hex
nuts (427L).
13. Fully secure the wet end to the pedestal by installing the hex head capscrews (370Y)
through the holes in the pedestal's lower front ring into the gland half casing (100D).
14. Loosen the bearing adjustment frame threaded rod nuts (415A) on the forward (wet end)
side of the adjustment plates by turning them clockwise.
15. Loosen the hold-down bolts (352G) and nuts (427D) that clamp the adjustment plates
(234F) to the bearing cartridge housing (228) but do NOT remove. Bolts should remain
finger-tightened to keep the bearing frame constrained to the pedestal while allowing it to
slide along the pedestal rails.
16. Slide the bearing frame forward until the shaft (122) threads are inside the wet end and
engaged with the impeller (101).
17. Turn the shaft (122) clockwise to re-engage the shaft threads to the impeller. This will
cause the bearing frame to move forward on the pedestal until the shaft is fully threaded to
the impeller. Note: This will take 4 - 5 complete shaft turns.
18. Loosen the three adjustable seal ring jam nuts (357A) by turning them clockwise.
19. Turn the seal ring square head adjusting bolts (356F) sequentially, clockwise 1/3 of a turn
at a time, to move the adjustable seal ring backward in the casing until it is firmly seated
against the suction side liner (562).
20. Adjust the impeller gap (refer to the Maintenance section for instructions).
21. Fully tighten the hold-down bolts (352G) and nute (427D) that clamp the adjustment plates
(234F) to the bearing cartridge housing (228).
22. Tighten the bearing adjustment frame threaded rod nuts (415A) on the forward (wet end)
side of the adjustment plates by turning them counterclockwise.
23. Adjust the seal ring gap (refer to the Maintenance section for instructions).
24. Install the packing (106) and lantern ring (105).
25. Assemble and install the gland assembly (107) using the gland adjusting bolts (353).
Wet end assembly instructions
The following steps are used to assemble the wet end in sequential fashion for the XHD Value
Option model, as well as the XHD model when the complete wet end connection option is not
employed.
Install the knock-off ring
1. Coat the shaft (122) protuberance with an anti-seize compound.
2. Loosen but do not remove the hex head screws holding the knock-off ring assembly (149)
halves together.
3. Position the knock-off ring onto the shaft (122) and make sure that the part is properly
oriented. The side of the knock-off ring that should face the impeller is marked "THIS SIDE
OUT".
