29.Pick-up assembled volute and assemble to motor frame (aa) with

four bolts (ai) and four lockwashers (aj).

30.Slide sleeve (bd) onto rotor shaft. Press into place. Sleeve should

fit inside oil seal (bc) previously assembled to volute.

31.Slide thin shim (be) onto rotor shaft.

32.Apply oil to key (aq) then place into keyslot of rotor shaft.

33.Align impeller key with rotor shaft keyway and slide impeller (bf)

onto rotor shaft.

34.Secure impeller with thread cover (as), lockwasher (at) and acorn

nut (au).

35.While keeping impeller and rotor shaft from rotating, tighten acorn

nut (au).

47.Position gasket (av) and suction cover (aw) to housing cover and

secure with three bolts (ay) and three washers (ax). Thread the

longest end of the bolt into volute. With suction cover secure,

measure the clearance between impeller and suction cover.

36.Measure the distance between the impeller and the volute after

assembly. Keep a recommended clearance of 0.3–0.5mm (0.118–

0.196in).

Note: If necessary, add (or remove) gaskets to obtain proper

clearance.

—If the measured distance between the impeller is greater than

0.5mm (0.196in), the pumping capacity drops.

—If the measured distance between the impeller is less than

0.3mm (0.118in), the impeller may contact the volute and slow

rotation, overload the motor causing premature failure.

37.Position strainer (az) to three protruding stud bolts (ay) and secure

with three nuts (bb) and three lockwashers (ba).

38.Turn pump on its side and remove oil plug (op) with plug gasket

(pg) attached.
