4.4.7 Install coupling
NOTE Not all components or sub-
assemblies of a pumping unit are
necessarily supplied by Flowserve
or part of this delivery.
These user instructions apply only
to the components or sub-
assemblies supplied by Flowserve
in this delivery, see Chapter 12.1
"Scope of delivery".
The coupling between motor and pump bowl as-
sembly depends on the type of pump bowl assem-
bly delivered.
Flowserve manufactures two coupling variants for
the Byron Jackson Double Mechanical Seal Motor:
•
Variant A: Motor half coupling
•
Variant B: One-piece coupling
Both are described in the following. See Chapter
12.1 "Scope of delivery" to determine the coupling
delivered and follow the respective instructions.
Variant A: Motor half coupling
1. Motor half coupling is factory installed. Refer
to Figure 11.
2. Clean coupling and shaft, and lightly oil both.
3. Slip coupling on shaft with keyways aligned.
NOTE Do not attempt to force the cou-
pling.
If the coupling will not seat freely:
- remove the coupling
- verify that the shaft is free of dirt
and foreign matter
- replace the coupling.
4. Insert key (676-1), round end down, in the
keyway.
5. Install socket head set screw (806-1) through
its hole in the coupling (529) to engage its
hole in the shaft.
Use wrench provided to tighten set screw
(806-1).
6. Identify the shaft adjusting button (130),
alignment jig (265), screws (806-3) with
washers (690-4), shaft button screw (806-2)
and shims (262-6 and 262-7).
7. Remove string from shaft button screw
(806-2) which holds shim in place.
Verify that the shims (262-6 and 262-7) are
attached to the screw (806-2).
8. Install alignment jig assembly in motor half
coupling (265).
9. Install cap screw (806-2) and use wrench pro-
vided to tighten screw (806-2).
10. Remove the coupling lock screws (806-3) and
washers (690-4).
Set these pieces aside for later use (see
Chapter 4.4.8 "Install pump bowl assembly",
Page 30).
11. Remove alignment jig (265) and hold for stor-
age in motor shipping cap (112-1).
12. Clean the motor flange face of any dirt or for-
eign matter.
Verify that the balance line hole in the flange
face is open and clear.
13. Cover the coupling (529) and shaft with a
clean cloth.
The motor is now ready to receive the pump bowl
assembly.
