3. Visually inspect volute (aa) for wear and damage. Look for signs of

wear on volute cutwaters and surfaces facing impeller.

6.5.3.3 Impeller Clearance

1. Measure the distance between impeller and volute after assembly.

Keep a recommended clearance of 0.3–0.5mm (0.118–0.196in).

—If measured distance between impeller is greater than 0.5mm

(0.196in), pumping capacity drops.

—If measured distance between impeller is less than 0.3mm

(0.118in), impeller may contact volute, slow rotation, overload

motor and cause premature failure.

6.5.3.4 Impeller Reassembly

Note: Draining oil is not required to disassemble, inspect and

replace impeller. However, if further disassembly and testing

is required, drain oil.

Note: If, upon inspection and testing, a pump component requires

replacement, use only original manufacturer’s replacement

parts.

1. With the pump on its side, replace the key (bi) properly in the

keyway of the rotor shaft.

2. Align and install impeller (am) over keyway of rotor shaft.

Note: Impeller vanes may be very sharp due to excessive wear.

Handle with care.
