Diameter of rotating member at clearance Minimum diametrical clearance
600.00 to 624.99 24.000 to 24.999 0.91 0.036
625.00 to 649.99 25.000 to 25.999 0.94 0.037
For diameters greater than 649.99 mm | 25.999 in., the minimum diametrical clearances shall be
0.94 mm | 0.037 in. plus 1 mm for each additional 1 mm | 0.001 inch for each additional inch of diameter
or fraction thereof .

6.6.1 Assemble the rotating element
WARNING:
Lifting and handling heavy equipment poses a crush hazard. Use caution during lifting and
handling and wear appropriate Personal Protective Equipment (PPE, such as steel-toed shoes,
gloves, etc.) at all times. Seek assistance if necessary.
NOTICE:
• Make sure that all parts and threads are clean and that you have followed all directions
under the Preassembly inspections section.
• Check for magnetism on the pump shaft and demagnetize the shaft if there is any de-
tectable magnetism. Magnetism attracts ferritic objects to the impeller, seal, and bearings
which can result in excessive heat generation, sparks, and premature failure.
1. Assemble the impeller onto the shaft. The impeller is a slip fit onto the shaft (0.0127 mm to 0.0508
mm | 0.0005 in. to 0.002 in. clearance). Position the impeller to the X value recorded during disas-
sembly, or refer to the Impeller setting table in the Disassembly section. Apply a liberal amount of
an anti-seize compound onto the shaft.

2. Assemble the impeller locknuts.
One locknut has a right-hand thread, the other one has a left-hand thread.
If this is a repair, it is likely that only one locknut was removed. Keep the second locknut on the
shaft in order to maintain the impeller centering. Use the previously recorded dimension from the
bearing shoulder to the face of the impeller hub, or refer to the Impeller setting table in the Disas-
sembly section.
