6) If
bracket screw plugs
(Ref. #12) are provided,
press them into the hole over each bracket screw.
The hole in the plug should face up
(Fig. 8). Used
only on pumps designed for non-metallic solution
contact.
7) Lubricate the seal ring of your impeller with
vegetable oil. Place the impeller completely onto
the shaft by placing pressure onto the impeller hub.
With full pressure applied, slowly rotate the impel-
ler to insure that it does not touch the bracket. If
the impeller touches the bracket, add one or more
impeller shims (Ref. #30) under the impeller hub
until clearance is obtained. Remove the impeller,
insert the key into the impeller keyway and slide
the impeller onto the shaft (Fig. 9, 10, & 11).
Note: A small dab of Crisco vegetable shorten-
ing on the key will help hold it in place during
assembly.
