Drive Arrangement With APS Set-Up for High Range

Small Seeds Attachment
(Optional)
There is no “range” associated with Small Seeds drive. If
set correctly, the Small Seeds box should turn the same
speed regardless of whether the main seed box is set for
high or low range. Study the seeds charts and install
sprockets and roller chains accordingly.
Drive Arrangement with APS in High Range
Refer to Figure 3-8:
The 19/35T Sprocket (#3) is arranged with the
19T sprocket in front of the 35T sprocket and the 16/29T
sprocket (#6) is arranged with the 29T sprocket in front of
the 16T sprocket. All other sprockets remain unchanged.
Main Seeds Box Drive Arrangement
1.
Loosen 3/8" nut securing drive tension sprocket (#5).
Remove drive chain (#4) from sprocket (#3).
2.
Pull idler sprocket (#1) away from roller chain (#2)
and remove chain from sprocket (#3).
3.
Remove 5/8" nut and flat washer from center of
sprocket (#3).
4.
Rearrange sprocket (#3) so that the 19T sprocket is
in front of the 35T sprocket and then replace 5/8" flat
washer and lock nut. Torque nut tight.
5.
Drive chain (#4) should be 65 pitches long and driven
chain (#2) 101 pitches long. If drive chain (#4) has 73
pitches, then remove 8 pitches from it and add those
pitches to driven chain (#2).
6.
Install drive chain (#2) onto 35T sprocket (#3) and
then driven chain (#4) onto 19T sprocket (#3).
Small Seeds Box Drive Arrangement
1.
Loosen the 5/8" nuts located at the center of idler
sprockets (#6 & #10).
2.
Loosen 3/8" cap screws securing idler slide
plates (#11 & #12).
3.
Remove roller chains (#7 & #8) from sprocket (#6).
4.
Remove 5/8" nut, lock washer, and 1/4" long spacer
tube from center of idler sprocket (#6).
5.
Rearrange sprocket (#11) so that the 29T sprocket is
in front of the 16T sprocket and then replace
1/4" long spacer tube, lock washer, and 5/8" hex nut.
Draw nut up snug. Do not tighten.
6.
Install roller chain (#8) onto 16T sprocket (#6) and
then roller chain (#7) onto 29T sprocket (#6).
7.
At the same time, reposition sprockets (#6 & #10) to
remove excess slack in roller chains (#7 & #8).
8.
Secure lower idler slide plate (#12) by drawing the
3/8" cap screws up snug. Maker sure they are loose
enough to make final adjustments to the sprockets by
tapping on the idler plate with a hammer and punch.
9.
Adjust upper idler plate (#11) to remove any
remaining slack out of both chains (#7 & #8) and then
secure the plate by drawing the 3/8" cap screws up
snug. Make sure cap screws are loose enough to
make final adjustments to the sprockets by tapping
on the idler plate with a hammer and punch.
10. Tap on idler plates (#11 & #12) until chains (#7 & #8)
have a small amount of slack. If necessary, slightly
loosen 5/8" center sprocket nuts to reposition
sprockets (#6 & #10) on their idler plates.
11. Once the chains are properly tensioned, tighten the
3/8" cap screws on the idler plates and 5/8" nuts in
the center of the sprockets to the correct torque.
NOTE: The remaining steps are easier if completed
by 2 people.
