b) Secure the columns with capscrews and hex nuts until all column and lineshaft sections required
for the proper pump setting are assembled.
c) Tighten the capscrews into the hex nuts gradually and uniformly.
Install the enclosed lineshaft
CAUTION:
Do not use automotive oils.
Pump lineshafts are connected with either threaded or keyed couplings. This section describes both
procedures.
See the Certified Pump Outline Drawing for the number of column and shaft sections required.
1. Check the headshaft and lineshaft for straightness.
The average TIR should be less than 0.0005 in. (0.013 mm) per ft. (0.305 m) and not exceed 0.005 in.
(0.127 mm) for every 10 ft. (3 m).
2. Install the coupling:
If your
lineshaft
coupling
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.
For an illustration of the threaded coupling, see the VIT-FF product lube in the Parts List
chapter.
Keyed 1. Insert the key into the pump shaft.
2. Lower the sleeve over the pump shaft, to approximately 1.0 in. (25.4 mm) 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.
