General Assembly Instructions
This manual provides assembly instructions for the Chain and Paddle Drag Systems for use with NexGen 2000 &
3000 SERIES Klean Sweeps.
The drag sections should be assembled as close to the sweep assembly as possible. This minimizes the
movement of the drag system and/or sweep assembly when joining them together. Use the charts in Section –
Drag Length and Section Charts on page 8 to assist with the assembly process. When completed, the drag
system and sweep auger should resemble the following illustration.
Figure 1. Completed Assembly
The middle drag sections can be multiple lengths
(refer to the charts for section lengths and sequence
of assembly).
These sections will be assembled in the same
sequence length as the sweep auger & flight sections,
the flanged end of the drag section should be located
at each bearing support of the sweep auger.
Install tractor(s) only after
the drag sections have been
installed

Best practice is to assemble the drag sections together before installing them onto the sweep system.
Before beginning assembly read through these instructions and lay out all items from the kit to ensure all parts
are accounted for. This not only helps you become familiar with the parts and the assembly procedures, but also
makes you aware of what tools, equipment or materials you may need to complete the installation process.
Do Not enter the bin unless all power driven equipment has been shutdown and locked out.
Electric motors and controls shall be installed by a qualified electrician and must meet the
standards set by the National Electric Code and all local and state codes.
Assembly Methods
There are a couple of methods that work for assembling the sections and installing the chain and paddles:
1. Assemble the drag sections together, keeping the sections upright. Then, using a wire, rope or similar item,
pull the chain and paddles through each section. (The access doors can be used to help route the chain and
paddles over the return rollers).
2. Assemble the sections together, then flip them upside down to install the chain and paddles from the
bottom side. (See illustration and instructions in Section – Install the Chain and Paddles on page 4). This
method can be useful as it allows easier access around the return rollers, as well as when connecting the
chain lengths together.
The following sections describe both methods.
Assemble the Drag Sections
The entrance end section, and the middle sections, come pre-assembled with return rollers. The tail section is
pre-assembled with return rollers, bearings, tail shaft and sprocket.
1. Assemble the drag sections together (entrance end nearest bin center, tail section nearest bin wall).
The length of the middle section(s) is determined by bin diameter.
To properly assemble the drag sections in sequential order, refer to Section Charts:
2085 Tru-Klean Drag Section on page 9 and
3150 Tru-Klean Drag Section on page 8
2. Secure all drag sections together using 3/8” x 1” bolts and nylon locknuts.
3. Attach the head weldment to the entrance section using 3/8” x 1-1/4” bolts and nylon locknuts.
4. Remove access panel and doors to make it easier to route the chain and paddles. (Retain the hardware to
use when re-installing the doors).

3. Insert the 1-1/2” diameter end of the head shaft through the opening in the side panel of the head section.
4. From the inside of the head section, slide on the sprocket making sure the 3/8” x 2” key is in place. Make
sure the sprocket hub is facing the bearing.
5. Pass the end of the shaft through the bearing until the end of shaft is flush with the outside of the lock
collar.
6. Secure the lock collar.
7. Center the sprocket onto the head shaft making sure key is positioned properly.
8. Tighten setscrew to lock sprocket into place.
9. Before installing the chain, use the adjustment bolts at the tail section and move the tail shaft sprocket as
far back as the adjustment allows. (See Figure 4).

Method 1
1. Leave the sections upright, and use rope or similar to pull the chain through each section.
2. Remove the end cover from the tail section.
3. Route the chain and paddles around the entrance and tail section sprockets.
4. Use the access doors along the length of each section to help route the chain over the return rollers.
5. Using the provided connecting links, continue until all sections of chains have been installed.
Method 2
1. With the drag sections in the upright position, and the paddles oriented in the proper direction (angle
towards bin center), start one section of chain and paddles at the entrance end.
2. Keeping the length of chain and paddles in place, flip the sections over and route the remaining lengths of
chain so they remain oriented the same as the first length.

3. After the chain and paddles have been installed, position the drag sections so they are upright.
Set the Chain Tension
1. Make sure the drag sections are in the upright position to determine proper tension.
2. It may be necessary to remove one or more links of chain in order for the chain to achieve proper tension.
3. Using the adjustment bolts at the tail section, turn both sides equally in small increments until desired
tension is achieved.
Note
The chain and paddles will sag and contact the bin floor, even with the drag mounted to the sweep
auger.
4. Make sure there is minimal slack in the upper chain sections as they cross over the return rollers.
Attach the Drag Sections to the Sweep Auger
1. With the drag section in the upright position, slide the sections into position along the back side and under
the sweep auger.
2. Align the two mounting tabs on the head section with the tabs welded onto the sweep shield frame (See
Figure 7).
3. Insert a 3/8” x 1–1/4” bolt through the mount tabs and secure with 3/8” flat washer and 3/8” nylon locknut.
(Leave hardware loose at this time).

Note
For additional information about installation and maintenance of the gearbox, record the serial number
of your gearbox and go to www.nord.com/docs and download the appropriate information.
Installing the coupler
The gearbox is supplied with a coupler. You will install the coupler onto the motor shaft prior to mounting the
motor to the gearbox. (See Figure 13). The location of the coupler on the motor shaft is referred to as the
“Coupling Placement Distance.
1. Use the provided template to properly locate the coupler onto the motor shaft.
2. Slide the coupler onto the motor shaft.
3. Position the template as shown in Figure 13.

4. Make sure the coupler is contacting the template and tighten setscrew to lock the coupler into place.
It is recommended that the key be bonded in place (using Loctite) to help keep the key from vibrating out.
5. With the coupler locked into place, take measurements of the coupler’s placement distance as shown in
Figure 14.
6. Record the measured dimensions.

7. If it ever becomes necessary to relocate the coupler, and the template is not available, the following
calculation can be used to properly locate the coupler:
Calculating “Coupling Placement Distance”
a. Measure the distance from the face of the input adapter of the gearbox to the edge of the gearbox
flange as shown in Figure 14.
b. Record this measurement as “A”.
c. Measure the depth of the “coupling engagement zone”.
d. Record this measurement as “B”.
e. Add A + B and subtract 0.080” (2 mm) as shown in Figure 15.
Figure 15. Coupling Placement Distance calculation
Note
The 0.080” (2 mm) value is added to ensure the coupling is not pre-loaded after installation).
f. Use the calculated value as the Coupling Placement Distance.
8. Measuring from the flat surface of the motor mounting flange, position the front edge of the coupling at
that distance and tighten the setscrew to lock the coupling in place. (See Figure 14).
9. After the coupler is properly installed onto the motor shaft, position the motor onto the gearbox, oriented
as shown in Figure 16.
10. Secure motor using the 3/8” x 1-1/2” bolts provided with the motor.

Maintenance
Maintenance Safety
Keep components in good condition. Follow the maintenance procedures.
Ensure the service area is clean, dry, and has sufficient lighting.
Do not modify any components without written authorization from the manufacturer.
Modification can be dangerous and result in serious injuries.
Shut down and lock out power before maintaining equipment.
Never enter the bin unless all power driven equipment has been Shut/Down and Locked
Out.
Never attempt to control the operation of the sweep by pushing, or pulling on it with
brooms, shovels, boards or any other device.
After maintenance is complete, replace all guards, service doors, and/or covers.
Use only genuine Hutchinson | Mayrath replacement parts or equivalent. Use of
unauthorized parts will void warranty. If in doubt, contact Hutchinson | Mayrath or your
local dealer.
Maintenance Procedures
For more detailed instructions related to the gearbox, visit www.nord.com/docs and use the serial number of
the gearbox to download the appropriate operating instructions (see Figure 18 below).

Check Oil Level:
Important
The gearbox is shipped with oil already installed. Even under normal working conditions, oil still has a
tendency to dissipate. Periodically check oil level and maintain proper level.
Oil Type ISO Viscosity VG220
MIN-EP Mobilgear 600XP220
Ambient Temperature 32°F to 104°F (0°C to 40°C)
Capacity Approx. 2.2 qts. (2.14 L)
1. With the gearbox in the upright position, remove the level check/fill plug shown in Figure 19.
2. Oil should begin to leak from the opening to indicate the oil level is correct. Replace plug.
3. If oil does not leak out, add oil through the opening until oil begins to leak out indicating oil level is correct
(a small funnel, pipe nipple or syringe type tool can be used to add the oil). Replace plug.
Note
Do Not overfill. Additional oil may damage the seals or be forced through the vent plug.
4. Replace the plug.
Important
To prevent build-up of excessive pressure, sealed vents must be activated prior to gearbox
operation.
Figure 19. Gearbox Oil Level and Sealing Plug
Important
Dispose of used oil responsibly. Follow all local regulations for proper handling and disposing of used oil.
At Least Once Every 6 Months
Perform a visual inspection. Check all fasteners for tightness.
Check paddles for wear, replace as necessary.
Check for broken and missing parts.
Ensure electrical wiring and connections are tight and not damaged.
At Least Once Annually
Lubricate the tail and head bearings (1 to 2 pumps is usually sufficient). Use a good quality lithium-based
grease.

Type
Installation guide

AGI NexGen 2085/3150 TRU-KLEAN Sweeps Chain & Paddle Drag Systems are designed to work with NexGen 2000 & 3000 SERIES Klean Sweeps. They are used to move grain from the center of the bin to the sweep auger, which then moves the grain to the center for unloading. The drag sections are assembled in sequential order and attached to the sweep auger. The chain and paddles are then installed, and the tension is set. The drag sections are then attached to the sweep auger and the motor cover mount bracket is installed.
