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).

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).

Install the Electric Motor to the Gearbox

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

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.

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.
