6.6.2 Install the rotating element assembly
1.
Use straps and a crane to insert the rotating element into the casing. Use precaution to not scuff the
impellers (101 and 145), impeller nut (124), or throat bushing surface.
a) Assemble new spacer gasket (351W) on the casing spacer (443D). Apply a liberal amount of
high-vacuum grease to hold the gasket in place.
b) Insert the rotating element enough to support the radial end of the shaft in the throat bushing
bore of the casing (100). This will prevent the pump from slipping and causing possible human
injury.
c)
Reposition the straps and slide the rotating element the remainder of the way into the casing
(100).

NOTICE:
Make sure to position the shaft fully into the radial end of the pump before starting the head-to-
casing assembly. This prevents damage to the internal components.
