GEARBOX RETRO FIT KIT, PART NO. 1039008

for use with the

10” HEAVY DUTY POWER SWEEP

(using 1034570 gearbox to replace 1025102 gearbox)

July 20, 2011

Install Gearbox

1. Before disassembly of the old gearbox, verify the

distance from the outside of the sweep wheel to

the closest section of the bin wall (See Fig. 1).

Measure the distance from the bottom of the shield

and flight to the bin floor and write this dimension

down for later reference.

WARNING! Do Not enter the bin unless

all power driven equipment has been

shutdown and locked out.

This gearbox will lengthen the power sweep by 2 1/2”

(64 mm) and decreases the center distance between

the original upper and lower gearbox by 2” (51 mm).

Generally there is plenty of room at the end of the

sweep for the additional length and there is about 2”

(51 mm) of clearance from the sweep to the bin floor.

However, if there should not be enough room for the

additional length, modifications to the sweep will need

to be made at the time of reassembly.

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.

2. Remove and retain the 5/8” x 1 1/2” bolt and locknut

that is used to attach the shield bracket to the

gearbox bracket (See Fig. 2).

3. Disconnect the u-joint from the gearbox by

removing the 3/8” x 2 1/2” bolt and locknut (be

careful not to lose the 1/4” x 1 1/2” key on the

gearbox shaft). Retain the key and hardware for

reassembly.

4. Remove the cover door on the center well to gain

access to the chain. Disconnect the spring from

the tensioner to relieve tension on the chain and

remove chain (See Fig. 2). Retain chain and half

link for reassembly.

Fig. 2

5. Measure the distance from the outside of the

sprocket from which the chain was previously

removed, to where the bottom side of the cover

door would be located [this distance is generally

around 1” (25 mm)]. See Fig. 3.

6. Next, determine how much to cut out of the center

panel to relocate the lower box of the new 1034570

gearbox.

This is determined by taking the measurement

from the bottom of the sweep to the bin floor (this

measurement was taken in Step 1 and recorded

for later reference). Subtract 2” (51 mm) from this

measurement, then add the desired distance from

bottom of sweep to bin floor (be sure to allow for

bolt heads and other obstructions that may be

present in the bin floor).

Example: If the sweep flight was 2 1/2” (64 mm)

off the bin floor and 1 1/2” (38 mm) was desired

distance after installation of the new gearbox, the

formula would be: 2 1/2” - 2” + X = 1 1/2” (X = 1”),

(64 mm - 51 mm + X = 38 mm) (X = 25 mm).

This means you would need to raise the lower

gearbox 1” (25 mm) from its current position to

achieve the desired distance of 1 1/2” (38 mm) from

the sweep to bin floor.

If the value for X is larger than the measurement

taken in Step 5 (top of sprocket to bottom of cover

door), there will need to be some additional

modification to the cover door.

7. Check the distance from the bottom of the cover

door to the center of the shaft on the lower gearbox

(See Fig. 4). Verify if there is enough room to

simply slide the lower box up the desired amount

that was determined in Step 6 (this may be possible

with some wells and gearboxes).

If there is enough room, continue with Step 8 then

go to Step 10. If there is not enough room, continue

with Step 8 and then go to Step 9.

Fig. 4

8. Remove the old gearbox, both gearbox brackets

and the driven sprocket and two-bolt flange bearing

(See Fig. 5). Retain all hardware for use when

reassembling.

Fig. 5

Cut the larger hole in the panel to allow the lower

gearbox shaft to be raised the needed distance

that was determined in Step 7 (See Fig. 6).

Be sure to protect the clutch assembly and nylon

rollers from sparks and other debris. Clean all

metal filings and debris from area after cutting

has been completed.

10. Using the hardware previously retained, install the

new lateral bracket, gearbox support bracket and

the new gearbox. Install the new sweep shield

bracket onto the gearbox (See Fig. 7).

11. After the new gearbox has been installed and

secured into place, measure the distance from the

center of the shaft on the upper gearbox to the bin

floor (See Fig. 8, this dimension should equal the

radius of the flight, plus the desired distance

between the sweep and bin floor). If not, adjust

accordingly.

For example: If 7” (17.8 cm) is the diameter of the

sweep flight, you would have a 3 1/2” (89 mm)

radius. Add the desired distance of 1 1/2” (38 mm),

the distance from the center of the shaft to the bin

floor should be 5” (12.7 cm).

12. Place the two-bolt flange bearing onto the shaft of

the lower gearbox. Check to make sure the

bearing does not extend past the top portion of

the well. If it does, the bearing will need to be

rotated 90° from its original position, and its

mounting holes redrilled.

If necessary, rotate the bearing 90°,mark the

mounting holes and drill two 17/32” (13.5 mm) dia.

holes (See Fig. 9). Install the bearing using the

hardware previously retained and secure bearing

to shaft with the lock collar.

If the bearing does not extend past the top of the

well, you may still need to redrill the mounting

holes depending on how high the lower gearbox

was raised.

If necessary, drill two 17/32” (13.5 mm) dia. holes

or lengthen the existing slotted holes to reinstall

the bearing.

13. Replace the sprocket and chain using the hardware

previously retained. Place the cover door into

position and secure into place. Rotate the shaft

on the gear box to verify the cover door does not

interfere with the sprocket.

If the cover door does contact the sprocket, use

flat washers or similar means to space the cover

accordingly. Make sure to seal the gap between

the cover door and top of well.

14. Reinstall the u-joint, flight and shield. Check all

hardware to ensure it is tight and verify all parts

are properly installed.
