General Model 108 FLEX-AUGER® Feed Delivery System
6MA1714C
Capacities and Specifications of the 108 FLEX-AUGER®Feed Delivery
System
The Model 108 FLEX-AUGER®Feed Delivery System is available with either PVC or steel auger tubes. PVC
and steel tubes should not be mixed in a system.
DO NOT USE PVC AUGER TUBING WITH FEEDS CONTAINING CALCIUM. The steel auger tubes should
be used for feeds with calcium.
The Model 108 FLEX-AUGER®Feed Delivery System has an approximate conveying capacity* of 220 pounds
per minute (100 kg per minute), or 13,200 pounds per hour (6,000 kg per hour). A high capacity Model 108 system
may be ordered for applications requiring up to 250 pounds per minute (113 kg per minute). The maximum
recommended running time per day is 4 hours.
*Carrying capacities are based on feed density of 40 pounds per cubic foot or 640 kg per cubic meter.
The Model 108 is designed to carry feeds such as mash, crumbles, shelled corn, high moisture corn, or pellets up
to approximately 3/16” x 1/2" (4.7 x 12.7 mm) in size. Applications other than conveying poultry and livestock
rations will void the warranty.
Adequate support must be provided to prevent the tubes from sagging and support the weight of the Control Unit.
The auger, tubes, and feed weigh approximately 8 lbs/ft. (12 kg/m). The Control Unit weighs approximately 100
lbs. (45 kg).
MAXIMUM MOISTURE CONTENT OF CORN FOR THE MODEL 108 FLEX-AUGER®IS 27%.
MAXIMUM MOLASSES CONTENT IS 2%.

MA1714C
Planning the Feed Delivery System
Carefully plan the Model 108 Fill System installation. Make sure the system will not interfere with other
equipment, doors, windows, etc.
The charts below provide power unit recommendations and maximum system line lengths. The top chart applies
to standard 348 RPM systems. The lower chart applies to (optional) High Capacity 425 RPM systems.
*Maximum line lengths should be reduced for elevations over 8’ (2.4 m) and/or inclines steeper than 45 degrees.
Maximum lengths for 108 systems include use of two PVC elbows. If additional elbows are used, decrease line
length by 30 ft. (9 m) per elbow. Length of extension systems do not include elbows. Decrease maximum
extension system lengths by 30 ft. (9 m) per elbow if used in the system.
Horsepower requirements are based on length of the Model 108 FLEX-AUGER®system and type of system
installed--i.e. number of turns.
See the sections starting with “Model 108 Flex-Auger® Systems Bin Placement Chart” on page 10 for
typical bin to building placement using various elevations, boots, and screener options.
1.For the easiest installation and most trouble-free operation, locate the feed bin in a direct line with the FLEX-
AUGER®Feed Delivery System. The layout charts on page 10 and page 11 provide some points of reference
for bin placement according to the height at which the FLEX-AUGER®tube enters the building. Remember,
these are only examples. The layouts can be modified by changing the elbows, the tube sections, and/or the dis-
tance from the bin to the building.
FLEX-AUGER®Feed Delivery Systems operate best at an angle of no more than 60 degrees from horizontal
to the entry of the building at the desired height. Chore-Time considers a 45 degree elevation to be stan-
dard. The lower the angle, the more reliable the system.

Planning Model 108 FLEX-AUGER® Feed Delivery System

2.Lay out the system as straight as possible. Avoid extra elbows and curves by locating the feed bin in line with
the feeders. One horizontal 90 degree turn is permissible inside the building. 180 degree turns are not
recommended under any conditions.
If additional turns or elbows are required, use an Extension Boot. Remember: one 90 degree elbow
requires the same power as 30’ (9.1 m) of straight line.
3.Plan the system so that the auger tubes are directly over the feeders or hoppers to be filled, if possible. The
drop tubes may be angled to a maximum of 45 degrees from the vertical if necessary. At angles greater than
45 degrees, bridging in the drop tubes may occur.
4.The control unit must be located over a feeder or hopper that will require as much or more feed than any of
the other feeders or hoppers. If frequent filling is desired, mount the drop tube switch or hopper level switch
low so that this feeder or hopper will have a low feed level. This allows the feeder to call for feed more often,
the system will restart, and the other feeders will be refilled sooner.
5.Do not locate outlet drops on or just before an elbow. Install the drop after the elbow so feed will cushion the
auger through the curve. If there is some reason why the outlet drop cannot be moved, it must have some
"feed bypass" to cushion the auger through the elbow.
6.Avoid horizontal left-hand turns if possible. The elbow in a left-hand turn is not cushioned by the feed and
will wear faster. On systems with a 90 degree horizontal left-hand turn, reduce the stretch to reduce wear.
NOTE: A rule of thumb for left-hand turns is to reduce stretch to 6" per 50’ (150 mm per 15 m) of auger
on initial installation. After the system has been broken in, it may be necessary to increase the
auger stretch to prevent auger surging.
7.On any Extended Length System, balance the power requirements between the power unit that takes feed
from the bin and the power unit on the Extended Length System.
To do this, determine the total length of the system and divide by two. Subtract 20’ (6.1 m) from the standard
system and add 20’ (6.1 m) to the extended system.
Example: On a 240’ (73 m) system, the center of the system would be 120’ (36.5 m). Subtract 20’ (6.1 m)
from standard system, and add it to the extended length system. The first power unit should be located
approximately 100’ (30 m) down the system. Locate the second power unit approximately 140’ (42.7 m)
from the first power unit.

Model 108 Flex-Auger®Systems Bin Placement Chart
Use this chart to determine the distance from building to center of bin ("X") at the various entrance heights ("H")
and degrees of elevations listed below.
Degree of elevation = Angle at which the system is installed, including the 30 degree or straight-out Upper Boot.
These layout charts are for planning and reference purposes only. A combination of elbows and straight tube may
be required for your installation, depending on the distance from the bin to the building and the height at which
the auger tubes are to enter the building. The elbows may be easily cut to any angle required.
PAY PARTICULAR ATTENTION TO THE MINIMUM DISTANCE BETWEEN THE BIN AND THE
BUILDING.
Many installation and operational difficulties can be avoided if the bin is located farther from the building. If in
doubt, it is BETTER TO BE TOO FAR AWAY THAN TOO CLOSE.
The maximum recommended angle of elevation above the horizontal is 60 degrees. The maximum elevation is 30
feet (9.1 m) . . . if the angle of elevation is no more that 45 degrees.
All systems require adequate support of the auger tubes to prevent sagging and/or excessive forces being
transmitted to the bin boot.

Bin Location Information
For easiest installation and most trouble-free operation, locate the feed bin directly in line with the FLEX-
AUGER®System. The “Model 108 Flex-Auger® Systems Bin Placement Chart” on pages 10-13 provide
some points of reference for bin placement according to the height at which the system enters the building.
The 30 degree or straight-out boots combined with various elbow hookups offer a wide range of possibilities.
The charts are only for reference. Modify and adjust elbows and tube sections as needed.
NOTE: Two 45 degree PVC elbows are standard with Model 108 FLEX-AUGER®Delivery Systems. If
additional elbows are required they must be ordered separately.
The bin collar is installed during bin assembly. Chore-Time bins have a welded collar. Bin Adapter Kits are
available to modify existing bins so that the welded collar can be used. In addition, a Universal Adapter Plate
is available to allow the FLEX-AUGER®boot to be installed to other manufacturers’ bins.
Tighten all bin-seal bolts from the nut side. This prevents cutting and "spinning out" of the plastic washer.
Boot Installation
1.Insert the upper boot into the bin collar and turn it to line up with the direction that the auger line will go. The
boot must be as far up into the opening as it will go. Use the holes in the ring for drilling guides and drill 11/
32" (8.8 mm) holes in the upper rim of the boot. Attach the boot to the bin collar with the hardware provided.
See Figure 1.
MPORTANT: Failure to install the hardware as shown in Figure 1 may cause breakage of the red boot
body.
2.Attach the transfer plate to the upper boot. Use truss head bin-seal bolts installed from the inside of the plate,
with flat washers placed under the nuts.
3.Insert the slide into the transfer plate slot so that it is in its operating position before bolting the slide shield in
place. Remove the paper backing from the sealing strip before fastening the slide shield to the transfer plate.
Use two 5/16-18x3/4" hex head machine screws to secure the shield.
4.Bolt the lower boot to the transfer plate using four 5/16-18x3/4" hex head machine screws.
5.After the auger tubes and auger have been installed, attach the 6197 Clean-Out Cover Plate or the optional
Proximity Boot Switch to the lower boot.

Auger Tube Installation
The FLEX-AUGER®Delivery System includes two 45 degree elbows as standard equipment. These elbows are
used to make up the sloping portion of the auger line at the feed bin, and elsewhere in the system if necessary.
If additional elbows are required they should be ordered separately. Figure 2 shows how the elbow can be cut
into shorter sections.
Dimension PVC Steel
"A" 16.8" (43 cm) 16.3" (41 cm)
"B" 25.2" (64 cm) 24.4" (62 cm)
"C" 33.6" (85 cm) 32.5" (83 cm)
"D" 50.3" (128 cm) 48.8" (124 cm)
Note: All measurements are along the outside edge of the elbow.
Note: PVC elbows are belled. Dimensions shown do not include bell.
Figure 2.PVC Elbow Cutting Guidelines (Side View)

Installation Model 108 FLEX-AUGER® Feed Delivery System
16 MA1714C
1.Determine where the entrance hole for the auger tube must be located on the building and cut it.
2.If necessary, cut the elbow used where the auger enters the building. Slide the seal ring and neoprene seal
over the straight end of the elbow and place it in the hole cut in the building, with the belled end outside the
building. See Figure 3.
3.Clamp the belled end of the second elbow on the outlet end of the boot on the feed bin.
4.Place the straight end of a tube section inside the belled end of the elbow in the building. Hold the straight
section of auger tube so that it touches the elbow on the boot. Mark the spot where the tube touches the boot
elbow and cut the elbow at that point.
5.Place the belled end of the auger tube over the end of the elbow just cut, and hold the tube against the top
elbow. Mark and cut the straight auger tube so that it will fit between the two elbows.
Remember to cut the auger tube long enough to fit inside the belled end of the elbow in the building.
NOTE: In some installations it may be possible to eliminate the elbow on the boot, using only a straight
auger tube and one elbow where the auger tube enters the building.
6.Dry-fit all parts. When satisfied that elbows and tubes fit together smoothly, glue with PVC cement
according to the following instructions.
The auger tubes and elbows for the FLEX-AUGER®systems are made of specially formulated PVC tubing.
Use the PVC solvent cement to make strong, reliable bonds.
Follow the Directions on the can for Safe handling of cement
1. Be sure tube is cut off squarely. Remove burrs from outside and inside the end of the tube.
2. Dry fit all parts. Tube should fit inside belled end of next tube to full depth without excess force.
3. Clean surfaces to be joined. SURFACES MUST BE FREE OF DIRT OR GREASE!
4. Apply a generous coat of cement to both the inside of the belled end and outside of the other tube. Be sure
cement covers all of the joint area so there are no bare spots.
5. Quickly join the tubes, giving them a twisting motion to bring them into alignment as they are joined.
6. Keep pressure on the joint until the PVC cement sets up.
7.ALL TUBE JOINTS EXPOSED TO MOISTURE AND WEATHER MUST BE SEALED OR CAULKED
TO WATERPROOF THEM IN ADDITION TO CEMENTING OR CLAMPING THE JOINT.
8.If there are more than 15 feet (4.5 meters) of auger tube between the boot and the building, provide
additional support for the tubes so that the boot does not carry the weight of the auger. Extra support can be
achieved with cables or chain fastened to the bin legs and the auger tube.
9.Locate and cut the outlet holes as required and specified in Figure 4. on page 17.
10.Slide (2) Outlet Insert Rings onto the pipe at each outlet hole location. Each Outlet Assembly is shipped
with Insert Rings for both steel and PVC pipes. The 3/8" (10 mm) thick rings are for steel tube systems. The
1/4" (6 mm) thick rings are for PVC tube systems. Be sure to use the appropriate Insert Rings for your
system.
11.Install the remaining tubes in the system.
The PVC auger tubes should be fastened together using PVC cement.
Model 108 Tube connectors should be used to connect steel auger tubes.

Outlet Drop Installation
Cut the outlet hole in the auger tube. A
sabre saw or hacksaw is handy for making
the cuts when total feed dropout is desired.
See Figure 4. Use a file to remove burrs
from opening.
Note: For total feed drop out, outlet holes
should be 5-3/8" (137 mm). If some feed
carry over is required, outlet holes should
be 3-1/2" (90 mm).
See Figure 5. below for outlet drop
installation.
1.Wrap the rotary slide around the auger
tube. POSITION SLIDES IN SAME
DIRECTION FOR ALL DROPS SO THAT THE SLIDES WILL ALL OPERATE THE SAME WHEN
ROPES ARE PULLED.
2.Thread the rope through the ends of the rotary slide.
3.Tie the ends of the rotary slide together so that the ends of the rope are the same length.
4.Open rope guide holes molded into the drop halves. Use a 3/16" (5 mm) drill bit and power drill to make a good
hole for the rope.
NOTE: DO NOT OPEN THESE HOLES IF THE ROTARY SLIDE WILL NOT BE INSTALLED.
5.Thread the rope ends through the guide holes in the drop halves.
6.Position drop halves over the rotary slide and fasten the two halves together using hardware provided. See
Figure 5.
Insert Rings are provided for both Steel Systems (Thicker Rings) and PVC Systems (Thinner Rings).
Slide the Insert Rings (with Flanges out) into position between the outlet halves to serve as spacers. See Figure
5.
7.Test the operation of the rotary slide by pulling on the ends of the rope. Be sure the outlet drop is centered over
the outlet hole, then move the rotary slide to the open position (check by looking up through the drop opening)
and mark the short end of the rope where it goes through the guide hole.
Tie a knot in the rope at the marked spot to act as a stop for the rotary slide.
8.Install green and red indicator balls on the ends of the rope. Tie knots in the rope to hold the balls in place. Use
the green ball on the rope used to open the outlet drop. Use the red ball on the rope used to close the drop. This
will indicate if the Outlet Drop is open or closed.
9.Dab PVC cement around the auger tube to prevent the drop from shifting on the tube.
10.Two screws are supplied for use in the bottom of the drop to attach a drop tube to the system.

Supporting the System Inside the Building
Support the Auger Tubing with chain and "S" Hooks every 5 feet [1.5m]. Steel Tube systems require support
every 10 feet [3m]. The system should be restrained from swinging by using chain and "S" hooks to brace the
auger tube, every 20 feet [6m], as shown in Figure 6.
Horizontal elbows need to be supported in at least two places. Chain, screw hooks, and "S" hooks are supplied
as a suspension kit for supporting the equipment. Keep the line as level and straight as possible.
If Extension Hoppers, Outlet Drops with long angled Drop Tubes, or other loads are imposed on the system,
extra support will be required.
Power Units require extra support to resist the twisting encountered when the motor starts and stops. Use the
motor mount base, all of the "ears" on the gearhead as well as the suspension point provided on the 46800
Control Unit Box to support the Power Unit.
Adequate chain and "S" hooks are provided with each system to properly support it. Other means of
supporting the system are permissible as long as the system receives the correct support and the auger tube is
not dented or flattened.
When the auger tube passes through a side wall or partition, especially where it enters the building, the
opening should be made large enough so the auger tube can be supported without resting on the wall. If the
auger tube rests on the wall or partition, the auger tube may flatten out or become kinked--causing excessive
wear. See Figure 7.

Supporting the System Outside the Building
Some systems require additional support to avoid sagging auger tubes. This support must be adequate to support
the weight of the auger tubes filled with feed. Special attention should be given to avoid excessive pressure from
the auger being transferred to boot. Chain or cable suspended from the bin or building will not provide adequate
support for these systems.
Some common systems are shown in Figures 8 through 12, with the recommended supports.
Note:Supports must be designed to prevent (weight) loads from being transferred back onto the boot.
The auger tubes must be supported every 4-5 feet (1.2 to 1.5 m) for PVC systems and every 10 feet (3 m) for
steel systems.
