MAINTENANCE
4. Place stub shaft with parts assembled on motor shaft.
5. Stub shaft should be placed so after the pump adapter is installed, the distance between the
end of the stub shaft and the motor flange on the pump adapter is between
3 /
8
” and 3 /
4
”.
6. Tighten hex head cap screws evenly but not more than to allow the stub shaft to be moved by
gently tapping with a rubber or plastic tipped mallet. This will allow for possible adjustment
during setting of impeller clearance.
7. Assemble pump adapter (29) to motor with hex head cap screws (30) and washers (31).
Tighten hex head cap screws until tight.
8. Assemble casing (1) to pump adapter with nuts (13) and washers (14). Do not assemble
stationary seal components into casing. These parts should be assembled into casing
after the impeller clearance has been adjusted. Perform impeller clearance adjustment
without seals to prevent any damage to the seals.
9. Screw impeller (2) to stub shaft.
SETTING IMPELLER CLEARANCES WITHOUT SEALS

(0.6mm - 0.7mm). CL4311 and CL6410: Set clearance to 0.040" to 0.043" (1mm to 1.1mm).
