FOLLOW SAFETY INSTRUCTIONS
Carefully read all safety messages in this manual and on
your machine safety signs. Keep signs in good condition.
Replace missing or damaged safety signs. Be sure new
equipment components and repair parts include the current
safety signs. Replacement safety signs are available from
the manufacturer.
Know how to operate and adjust your UniDriv to obtain the
maximum efficiency. Do not let anyone operate without
instruction.
Keep your machinery in proper working condition. Unautho-
rized modifications to the machine may impair the function
and/or safety and affect machine life.
BURYINGTHE UNITWILLVOID YOURWARRANTY.
DO NOT OPERATE UNIDRIV INAN EMPTY BIN. To test the
unit in an empty bin, make sure no one is in the bin, then turn
power “on” and “off” immediately from the outside of the bin.
Do NOT let it run in an empty bin.
If you do not understand any part of this manual and need
assistance, contact your dealer.
OPERATE MOTOR PROPERLY
To avoid serious injury or death, stay away from unit and
make sure everyone is clear of the UniDriv before
starting or operating the unit.
All electrical connections should be made
in accordance with the National Electric Code. Be sure
equipment and bins are properly grounded.
Do not operate electric motor equipped units until
motors are properly grounded.
Disconnect power on electrical driven units before
resetting motor overloads.
Do not repetitively stop and start the drive in order to
free a plugged condition. Jogging the drive in this type of
condition can damage the equipment.

UniDriv
Always use safe
sturdy ladders.
AVOID FALLS
Be sure to anchor the bottom of any ladder being
used in a bin or silo to prevent it from slipping.
Because the Uni-Drive is suspended from chains in
the center, be cautious of positioning ladder against
the Uni-Drive. The Uni-Drive can move or swing from
the weight of a person climbing on the ladder.
Also, when setting a ladder against the Uni-Drive, a
vise grip or some other type of tie down should be
used in the front and back of the track drive unit. This
keeps the Uni-Drive from rolling or sliding around the
bin while service work is being performed.
During heavy service work, such as removing auger
drive, electric motors, or replacing electrical swivel,
tying the ladder to the main frame or some other solid
component is advised.
Climbing out on the main beam or augers from either
a ladder or the roof manhole should NEVER be
attempted.
If an unusual amount of service work needs to be
performed, lowering the unit onto saw horses might
be the safest way.
STAY CLEAR OF ROTATING PARTS
CAUTION SHOULD BE EXERCISED if it is
necessary to enter the bin while the UniDriv is in
operation.
Entanglement in rotating augers will cause
serious injury or death.
Keep all shields and covers in place at all times.
Wear close fitting clothing. Stop and lock out
power source before making adjustments,
cleaning, or maintaining equipment.

lance service, hospital, and fire department near
yourtelephone.
WEAR PROTECTIVE CLOTHING
Wear close fitting clothing and safety equipment
appropriate to the job.
Safety glasses should be worn at all times to
protect eyes from debris.
Wear gloves to protect your hands from sharp
edges on plastic or steel parts.

Preface
The instructions for assembly are organized into sections dealing with vari-
ous assemblies on the UniDriv. Following the step by step instructions will
save time in overall installation as many tips gained through field experience
are provided. Close attention to assembly dimensions and installation se-
quences will avoid later problems in installation and operation.
DATE OF INSTALLATION:

11
Track InstallationUniDriv
Section 1 Track Installation
1. Refer to Figure 1-1. Pre-assemble the lug (256004) using the 3/8” x 1-1/4” Bolt (S-7767),
3/8” Hex Nut (S-7525), and 3/8” Lock Washer (S-1054) loosely to the Track Bracket .
Install the track bracket assemblies using the 5/16” x 1-1/2” Bin Bolt (S-277), 18-3/4” apart
around the inside bin wall eaves. Most bins have existing holes on 9-3/8” centers. If this is
the case install the track brackets using every other hole. If the hole in the bin wall panel
lies in the valley use an extra nut and washer as necessary to mount the bracket flush. The
bracket can now be used as a template for the bottom hole. Use the hole that best suits
the corrugation.
NOTE: The bracket must be bolted top and bottom.
2. Place a section of track into each track bracket so its bottom edge rests on the 3/8” x 1-1/
4” bolt between the lug and bracket.
3. Tighten the bolts to clamp the track in place.
4. Place a second section of track into the adjacent brackets so the end of the second
section of track butts against the end of the first section of track. See Figure 1-2. Note:
The track must be installed in the brackets so that the splice bolt holes are closest to the
bottom edge.
5. Using the 5/16” x 1” bolts (2FH5733) install a Track Splice (255002) behind and flush with
the bottom of the track. Tighten the splice so that the track section on the right is slightly
lower then the one on the left.
6. Cut the last track section to fit and drill the splice holes using the cut off piece as a
template.
NOTE: Caution must be taken to not leave a gap at the splice as it may cause the drive
wheels to slip.

For the following steps refer to Figures 3-1 and 3-2.
1. Slidetheadjustable hanger bracket(252050) on
the main beam until the edge of the bracket is 1
5/8” from the end of the beam. Secure in place
with the 1/2” x 1 1/2” bolt.
2. Place a clip angle on the 3/4” x 3” bolt (S-8981)
with the leg facing away from the bolt head.
3. Place a spacer on the 3/4” bolt.
4. Put the end of the hanger bar between the arms
of the hanger bracket so the hold is below the
arms.
5. Insert the 3/4” x 3” bolt through the hole in the
hangerbaruntilthehead ofthebolt holdsthe clip

Vertical Auger Stub Shaft Assemblies UniDriv
1. Depending on your unit size, refer to Figures 4-6, 4-7, and 4-8 for the following steps.
Place unit up on the saw horses inside bin, with the center hanger bracket directly
under the center roof hatch and the outer drive directly under the side roof hatch. Anchor
with boards 8” long with holes drilled so that you can bolt the unit to the saw horses for
stability. The Outer Drive can be allowed to pivot to a natural resting position during
assembly. DO NOT INSTALLMAIN MOTOR UNTILINSTRUCTED TO DO SO.
2. For your convenience the pulley, bearing, vertical drive spacers and sensing devices
have already been assembled to the stub augers, ready to bolt directly to the beam
brackets.The stub auger number should be affixed to the top of the topmost pulley of
each assembly. If for some reason the number has come off, compare the auger in
question with the other five (5) to determine which one it is.
3. The No. 4Auger (see Figure 4-4) will always go to the outer drive side of the main motor
and the No. 5Auger (see Figure 4-5) will always go to the center hanger side of the
main motor. TheseAssemblies contain the double 12"”cast motor belt pulleys.
4. The No. 2 (see Figure 4-2) and No. 3AugerAssemblies (see Figure 4-3) contain the
Sensing Devices and are placed at either end of the beam. No. 2 Stub Auger Assembly
is used in the high belt position and the No.3 Stub Auger Assembly in used in the low
position. Check overall beam drawing for your particular unit length for correct position-
ing.
5. The No. 1 Stub Auger Assembly (see Figure 4-1) is the standard double 9” pulley as-
sembly. It is used on all units of 5 augers or more and is placed between the two Motor
Pulley Augers and the outside Sensing Device Augers.
6. Installthe stubaugerassembliesusing the 3/8”x1-1/4” bolts (S-2071),Nuts(S-456),Lock
Washers (S-1054), and FlatWashers (S-248). Loose assemble thestubshaftassem-

7. Slow Down Kit Option
a. Assemble the stub shaft assembly with the 5” and 9” double pulley combination
next to the auger in the center of the bin. The 9” pulley should be assembled on the
topforthe24’,27’, 42’ and 48’ size units. (SeeFigure4-6) The5”pulleyshould be
assembled on top for the 30’, 33’, and 36’ size units. (See Figure 4-7)
