MECHANICAL SEAL REPLACEMENT
Refer to Seal Replacement Figures 1 & 2.
IMPORTANT: Always replace the seal assembly (Ref. No. 9)
to insure proper mating of components! Also, impeller o-ring
seal (Ref. No. 13) (where applicable) should be replaced if
worn or damaged anytime impeller nut (Ref. No. 14) has been
removed.
1. Unthread fasteners (Ref. No. 17) and remove pump casing
(Ref. No. 16) and casing seal (Ref. No. 15).
2. Remove impeller fastener, impeller seal (where applicable),
and impeller (Ref. No. 12).
3. Shims (Ref. No. 11), seal spacer (Ref. No. 10) and seal
head can now be pulled from shaft.
IMPORTANT: Care should be taken to ensure that the same
number of shim washers (Ref. No. 11) are replaced behind
impeller as were removed. These shim washers are located
directly behind impeller.
NOTE: Some motors (Ref. No. 1) use an open end 7/16"
wrench across flats on rear of motor shaft (remove bearing cap
for access) to prevent shaft from turning. Other motor shafts
have a screwdriver slot instead of flats.
