4. Install mechanical seal (69) or (70) using the following procedure:
a. Clean and oil sealing faces using a clean light oil (not grease).
CAUTION: Do not use oil on EPDM parts. Substitute glycerin or
soap and water.
b. Oil the outer surface of the seal seat, and push the assembly
into the seal bore in the bearing housing (1), or seal gland and
housing, seating it firmly and squarely. On double seal models
install seal gland on shaft.
c. After cleaning and oiling shaft, slide the seal body along the
shaft until it meets the seal seat.
d. Install seal spring and spring retainer or seal housing with O-
rings (72 and 270) on shaft.
5. The flexible joint (24) and rotor (22) may be installed using the
following procedure (do not bend joint more than 15 degrees):
a. Pin flexible joint (24) to shaft (26) using the shaft pin (46).
b. Pin rotor (22) to joint using rotor pin (46). Support joint while
installing pin.
6. Secure suction housing gasket (83) (cast iron pumps only) and
suction housing (2) to bearing housing (1) using lock washers
(215) and screws (112).

7. Slide stator support retainer (39) on stator (21).
8. Screw coupling (9) on stator (21) in a clockwise direction
(RH thread).
NOTE:
Apply pipe “dope” on all pipe threads before
assembly.
9. Lubricate rotor (22) surface to assist installation of stator
(21). Slide stator on rotor, and screw into suction housing
(2) by turning clockwise (RH threads). An additional assist
in installing stator is to lock the shaft from turning and
rotate the stator counter-clockwise while pushing towards
suction housing.
10. Secure clamp assembly (40) to the stator support (38) and
the support retainer (39) using the clamp assembly (40)
screw.
11. Proceed as in installation instructions.
WARNING: Replace belt or coupling guards before
reconnecting power.
