5. Hoist column section over pump, keeping tension

on tail rope. With column in a vertical position,

remove drag-line and traveling block, lower column

until bottom line shaft is properly aligned with

pump shaft coupling.

6. Apply a thin film of oil to the threads on the

lineshaft (646) and the coupling (649) (for non-

galling material or Molykote if galling material).

Use "MOLYKOTE" Dow Corning or

CAUTION

equal for all galling material such as 316

stainless steel.

7. With lineshaft in proper position on the coupling,

remove tail rope and screw lineshaft into coupling

until resistance is felt. A fine wire inserted in the

hole at the center of the coupling can be used as a

gage to determine when the coupling is correctly

positioned on the shaft. Remove the wire after

installing the shaft. Complete tightening the joint

by using a pair of pipe wrenches. Use care not to

damage any bearing journal areas of the shaft.

NOTE: Shaft threads are left-handed.

Make up threaded joints manually to

CAUTION

verify that the threads are properly

engaged prior to applying a wrench. If cross-threading

occurs, break the joint and repair the threads. If the

threads are beyond repair, replace the damaged part.

8. Carefully lower column section until lower end

of the tube section rests on the adapter bearing

(668). The end faces of the tube should be clean

and free of nicks. Remove tail rope, clean outside

of the adapter bearing and lubricate with thread

compound. Screw tube section onto adapter bushing

manually, until resistance is felt. Complete tube joint

by utilizing a pair of pipe wrenches or chain tongs,

butting the end of tube against the upper end of the

tube adapter bearing.

9. Clean column threads and lubricate with thread

compound.

10. Lower column until column pipe engages in the

COLUMN

discharge bowl. Manually thread the column into

discharge bowl. Complete joint by tightening

column, utilizing chain tongs until the end of the

column butts firmly against discharge bowl.

11. Lift the pump assembly and remove elevator clamp

secured to discharge bowl. Slowly lower assembly

into well or sump until elevator clamp gently comes

12. Remove the exposed lineshaft bearing, pour oil into

(CLAMP)

the tubing and reinstall the bearing. The amount of

oil to be poured is given in the following table:

Tube Size

1¼, 1½, 2

2½, 3, 3½

4 and larger

See pages 19-20 for recommended oil.

13. Repeat the preceding procedures. Throughout

the column assembly, install tube stabilizer (658)

over the enclosing tube (654) every 40 ft. The last

one should be less than 40 ft below the discharge

head. Use soapy water as lubricant when sliding the

stabilizer over the tube.

14. Continue the procedure until all column sections

for the proper setting have been installed, excluding

the column adjusting nipple (631) and tube nipple

(629), if provided.

15. Install the top shaft or stub shaft and coupling. If

pump is equipped with column adjusting nipple and

tube nipple, install them with longer threaded end

upward. Screw the lock ring (639) on to the column

nipple until the end of thread. (See page 13 for

adjustment instruction.)

CAUTION

cause serious damage to the pump and any downstream

components. Any foreign object dropped into the column

assembly must be retrieved prior to continuing assembly.
