Bearing Mount Locations
Refer to Figure 5.
13. Inspect each of the three partitions, and determine
on which side to mount the bearing. Pick whichever
side of the partition places the bearing center fur-
thest from both adjacent row unit seed cups
Note: By keeping the partition bearings clear of seed
cups, you minimize the number of agitators that
cannot be installed due to interference.
Install Bearings
14. Withdraw the shaft to the left of the left-most parti-
tion. Support the sprocket end so that the lever
action of the weight does not deform the box end.
15. Loosely assemble one bearing on the optimum side
of the left-most partition. Insert the screw from the
flangette side. Leave the bearings assemblies loose
until after full shaft insertion.
16. Insert the shaft into and a few inches beyond the left-
most partition bearing. The sprocket end no longer
requires support at this point.
17. Loosely assemble the remaining bearings on the
optimum side of their respective partitions.
18. Insert the shaft through all new bearings, and a few
inches beyond the right-most partition bearing.
Refer to Figure 3 on page 3
19. Select one saved:
LOCK COLLAR 3/4 HEX BORE
and slide it onto the free end of the hex shaft.
20. Insert the shaft through the right box end bearing.
21. Adjust the position of the shaft until the teeth of the
sprocket are aligned with the driving, driven and idler
sprockets of the Native Grass drive.
22. Without disturbing the position of the shaft, slide the
left lock collar against the left end bearing.
Tighten both set screws and secure the collar.
23. Slide the right collar up against the right end
bearing. Tighten both set screws, securing the collar.
