3.
Coat the seal cover-to-volute liner gasket (351Q) with lubricant and install into the casing volute lin-
er (561).
4.
Support the casing volute liner (561) using the proper end of the Goulds-provided impeller/casing
volute hook tool.
5.
Lift the liner into position and insert into the gland half casing (100D) using the installed retention
studs (353K) as a guide.

the volute liner retention hex nuts (355C).
6.4.6.10 Install the impeller - Metal-Lined
Two (2) people should work together to install the impeller for safety purposes.
1.
Loosen the adjustment plate bolts (352G) and nuts (427D) but DO NOT remove bolts or adjustment
plates (234F). Bolts should remain finger-tightened to keep rotating assembly constrained to the
pedestal.
2.
Slide the power end forward towards the suction side of the pump to allow better access to the shaft
(122) impeller threads.
3.
Apply anti-seize compound to the shaft (122) impeller threads.
4.
Lift the impeller (101) using a Goulds-provided impeller hook or a chain/sling threaded through a
vane passage attached to the hoist.
5.
Guide the impeller (101) into position to engage with the shaft impeller threads.
6.
With one person holding the impeller steady, the other should turn the shaft (122) clockwise to
screw the shaft into the impeller. Begin this operation by hand and finish with an adjustable spanner
wrench.

7.
After the shaft (122) has been tightly screwed into the impeller (101), the bearing frame can be slid
backwards toward the drive end until the impeller sits completely recessed in the casing volute liner
(561).
