General Information
These instructions explain how to install and adjust the sprocket-
box update. The sprocket box replaces the original gearbox on
Great Plains end-wheel drills. This modification improves the
performance and reliability of the original equipment.
These instructions apply to

Manual Update
Pages 4 and 5 of these instructions cover how to adjust the seed-
ing rate with the new sprocket box. These instructions replace
the "Clutch Shaft and Miter Gear Alignment" and "Seed Calibra-
tion" sections in the operator’s manual originally provided with
your drill. As reference, save pages 3 and 4 of these instructions
with your operator’s manual. A copy of the updated parts manual
is available through your Great Plains dealer.
Refer to the drill operator’s manual for detailed information on
safely operating, adjusting, troubleshooting and maintaining the
drill. Refer to the drill parts manual for part identification.

Assembly Instructions
Disassembling the Gearbox
1. Remove end-wheel-output and gearbox-output chains.
2. If your drill has 7-, 8- or 10-inch row spacings, you must in-
stall a new opener-lift arm and remove the existing arm. If
your drill has 6- or 7.5-inch row spacings, proceed to step 3.
To reposition the opener-lift arm, refer to Figure 1-1.
a. Assemble the clamp on the square opener shaft (1).
Place the channel bracket (2) over the link arms (3). Po-
sition the clamp 6 7/16 inches from the frame plate. Se-
cure to shaft with the mounting strap (4), 5/8-inch
washers and bolts.
b. Using a 3/4-inch clevis and cotter pin, pin the link arm
(5) to the newly installed clamp.

dimensions.
