8. Assemble the backplate and install the impeller. (See Figure
123.)
9. Before installing the
casing, visually inspect the impeller hub
and seal face to ensure that there is clearance between
them. If no clearance is visible, disassemble the pump and
move the stub shaft forward, to provide at least 0,032" (0,813
mm) clearance between the impeller hub and the seal seat
face. (See Figure 123.)
10. Reset the seal drive collar if
necessary. When the drive collar
is properly positioned and the seal components are properly
installed, the pump shaft should rotate freely by hand. If
excessive effort is required to rotate the shaft, check to be
sure that all components are properly installed.
11. Assemble the casing gasket and casing, and then install the
clamp
. Use a soft rubber mallet to line up the casing and
tighten the clamp, then install the guard assembly.
