1.
Use straps and a crane to insert the rotating element into the casing lower half. Use precaution to
not scuff the impeller (101), impeller nuts (124) and (130), or throat bushing surface.
2.
Slowly lower the rotating element into the case lower half. Make sure to center the impeller in the
discharge volute. Move and position the throat bushing, along with the case wear ring such that
these components are located on the proper bores and that the anti-rotation pins are fully seated in
their respective slots.
3.
Use straps and a crane assembly to assemble the upper half of the casing.
4.
Torque the bolts to the values found in the maximum torque values for fasteners table.
5.
Apply an anti-seize compound to the bolts and to the face of the head where the nuts make contact.
