If your line-
shaft cou-
pling is...
Then...
Threaded
1.
Apply a thin film of oil to the coupling threads if it is a non-galling material. Use a suitable
anti-seize if the coupling is a galling material.
2.
Manually start the thread until you feel resistance.
Use a fine wire inserted in the drill hole at the center of the coupling as a gauge
to determine when the coupling is correctly positioned on the shaft.
3.
Remove the wire after you install the coupling.
4.
Complete the joint using a pair of pipe wrenches, one on top of the pump shaft and the
other on the coupling.
5.
Run the upper lineshaft into the coupling and hand-tighten.
Do not apply wrenches on the bearing journal surfaces.
Keyed
1.
Insert the key into the pump shaft.
2.
Lower the sleeve over the pump shaft, to approximately 25.4 mm | 1.0 in. below the top of
the shaft.
3.
Lower the lineshaft until it touches the pump shaft.
4.
Insert the split ring into the grooves of the pump shaft and lineshaft.
5.
Raise the sleeve until it covers the split ring.
6.
Insert the key into the lineshaft.
7.
Raise the sleeve to the top of the key.
8.
Secure the sleeve to the split ring with a lock screw and lock wire.

Attach the column to the bowl assembly:
a) Attach a sling to the swivel hoist rings and to the hoist hook.
b) Hoist the column section towards the bowl assembly.
c)
Move the column over the lineshaft until the column flange engages the discharge-bowl flange
register.
d) Insert as many capscrews through both flanges as possible and gradually tighten them in dia-
metrically-opposite pairs.
