28 PNEG-914 Flex-Flo
Auger
The auger should be handled with great care. Do not install the auger until the kinks have been removed.
The kink may be removed by straightening the auger. A kink may cause extensive wear on the system
and premature part replacement. In the event that the kink cannot be removed by straightening, the kink
must be cut-out and the auger welded. (See brazing recommendations in
Figure 5X on Page 29 .)

Auger Installation
Two (2) persons are required to install the auger. One person feeds the auger into the tubing while the other
makes sure the auger is not damaged. Make sure no metal wires or loose ends enter the system.
1. The auger must be fed into the Flex-Flo System through the unloader. Remove the anchor from the
unloader. Remove the control unit cover plate as well.
2. Feed the auger carefully into the Flex-Flo System through the unloader. Remove the anchor from the
unloader and remove the control unit cover plate.
3. Push the auger in until it reaches the control unit at the other end. Fasten the end of the auger to the
clamp pin in the control unit driver assembly. Tighten the 5/16" hex head cap screw holding the auger
lock clamp pin to 23 ft-lbs. If the auger end is not in the appropriate orientation for connection, the
driver assembly may be rotated by turning the motor drive shaft.
4. Pull and release the free end of the auger gently a few times. This action should relax the auger into
its natural position.
5. A certain mechanical stress must be applied when installing the auger; therefore stretching the auger
is very important. This is performed by drawing the auger out of the tubing. An important factor is the
total system length. The auger should be drawn out of the tubing 2'' (5 cm) for every 50' (15 m) of
length for single feed tanks. For tandem systems, stretch the auger 4" (10 cm) for every 50' (15 m)
of length.
6. While the auger is in the relaxed state, mark the auger at the unloader inlet.
