Remove Center Shaft
Refer to Figure 6
(which depicts a 3PYPA center section shaft
)
35. Relax the idlers on the chain driving the shaft input
sprocket.
36. At each center section row, relax the row unit
idlers to slacken the final drive chain .
37. Along the line shaft :
- loosen all lock collar set screws (not shown)
- loosen all sprocket set screws (not shown)
- carefully drive out and save roll pins (not shown)
38. Make arrangements to support the free shaft
end . From one end, for example the RH end,
begin driving the shaft toward the other end.
39. Use a rag to clean the free end of the shaft . Mark
it (for example) “CTR LH END”. Shafts are often
section-specific and not symmetrical end-to-end.
40. Continue driving the shaft out. As the shaft exits
each collar and sprocket, recover and save these
parts. Some are re-used.
Remove Bearings (Conditional)
41. Check the materials list on the opener layout
drawing for your kit, found in “Swath Command™
Planter Clutch Layouts”, pages 48 through 97.
If the kit contains, for the center section, any:
402-273K TRU-COUNT SINGLE ROW ASM or
402-329K TRU-COUNT SHORT ROW SINGLE ASM
do not remove the bearings at rows indicated by the
drawing reference number for either of those clutch
kits.
Otherwise, remove and save the bearing assembly
and its fasteners, at every row.
Attach Locator Tools
Refer to Figure 7
(which depicts a 3PYP/A center section
)
42. In between the shaft-end marks made at step 31,
make additional marks at the positions:
1 ⁄
6
(17%),
1 ⁄
2
(50%) and
5 ⁄
6
(83%)
in between the end marks.
43. Attach one locator tool as close as practical to
each marked location. Each locator equally
supports
1 ⁄
3
of the shaft length at these positions.
Make sure tool is perpendicular to tool bar, and
snug front-to-back.
