NexGen 4X4 SWEEP TRACTOR UPGRADE KIT

PART NO. BK2406W-FT

for use with the

NexGen 2000 COMMERCIAL POWER SWEEP TRACTOR

October 1, 2014

1. Remove the top cover from the unit (a new top cover

will be installed after installation of the chain

tensioning components).

2. Remove the existing front and rear idler sprockets

(See Fig. 1).

3. Remove the four bolts and hardware securing the

gearbox to the frame. Note: the hardware securing

the gearbox will be used again for installation

of the upgrade kit with the exception of the

bolts. New 1/2” x 3” bolts are provided for use

with the kit.

Remove and discard the idler support bracket. The

spacer under the gearbox can be removed as well

and can also be used in conjunction with the spacers

provided in the kit.

Remove Existing Idler Sprockets

WARNING! A main power disconnect switch that can be locked only in the “Off” position

shall be used. This shall be locked whenever work is being done to any of the power

driven equipment.

Do Not enter the bin or storage structure unless all power driven equipment has been

shutdown and locked out.

Before beginning assembly it is suggested to 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.

Although it is not necessary to remove the upper frame

or rear tire from the unit to install this upgrade, you may

do so if desired. The following illustrations are shown

without these components for clarity only.

Assembly Instructions (con’t.)

Install Upgrade Kit

1. Position the appropriate number of spacers beneath

the gearbox to tighten the chain tension on the rear

chain. Use equal number of spacers on each side

of gearbox and adjust height to create enough

tension that the chain will not fall off the sprockets.

Secure the gearbox and spacers to the frame using

the 1/2” x 3” bolts provided in the kit, and the flat

washers, lock washers and nuts previously removed.

2. Insert the 3/8” x 2 1/4” bolt through the short tube

end of the tension arm. Thread a 3/8” non-lock nut

onto the bolt until snug, then back-off the nut enough

to allow the arm to pivot freely. Add a 3/8” flat washer

onto the end of the bolt (See illustration below).

3. Position the tension arm between the top and

bottom chain and fasten to the slotted bracket on

the side of the frame (same bracket front idler

sprocket was removed from, see below). Loosely

secure it to the bracket using one 3/8” flat washer

and 3/8” nylon locknut (flat washer against slotted

hole).

4. Assemble the tension arm, blocks and straps as

shown below. Secure the tension arm to the center

hole in the straps using one 3/8” x 3” bolt and nylon

locknut, and secure the tension blocks to the straps

using 5/16” x 3” bolts and nylon locknuts (the outer

holes or inner holes of the straps can be used to

adjust chain tension).

Tighten the bolt of the tension arm just enough to

allow the bar to pivot freely, this will ensure the

tension blocks will be able to “float” during operation.

5. Position the end of the tension arm in the slotted

bracket so the bar is horizontal. Tighten the nylon

locknut and non-lock nut against the bracket to

secure into place (ensure the tension arm can still

pivot freely on the bolt, this to will assist with the

tension blocks ability to “float” during operation).

6. Brush the chains with a good quality roller bearing

grease of medium consistency. Install the new top

cover provided with the upgrade kit.
