Install Wing Air Clutches
59. Connect the hitch hydraulics and harnesses at the
tractor.
60. a. For Model 3PYP and 3PYPA,
completely unfold the wings.
b. For all other Models,
Refer to Figure 8:
take note of the location of the
outside end of the line shaft . Partially or
completely fold the wings, leaving the wing-end
casters
oriented so that they do not obstruct shaft
removal.
61. Lower the openers.
62. Shut down the tractor. Disconnect hydraulics and
harnesses at hitch.
Start with the left wing.
Assess The Wing Shaft
Refer to Figure 8
(which depicts a YP24 left wing shaft
)
63. At one end of the wing, measure the length of
exposed meter drive shaft , from tip of shaft to
row unit mount sidewall (not to bearing face - the
bearing may be relocated during this installation).
Record the dimension.
Refer to Figure 9
(which depicts a YP40 left wing
)
64. Mark the approximate end-of-shaft locations on
the tool bar (needed for step 76).
65. Locate the 30T shaft input sprocket (not shown):
808-319C SPKT 50C30 X 7/8 HEX BORE
Measure the position of this sprocket with reference
to the row unit shanks on either side. Record these
dimensions, and whether the sprocket is secured in
place by no collars, one LH, one RH or two collars.
66. Locate any coupler on the shaft. Decide on a
removal/re-insertion strategy (both sections from
one end, or each section from each end).
67. Along the entire length of the shaft, locate each pin
hole and roll pin (not shown, and there may be
none, and there may be one coupler with two pins).
Clean the shaft near each hole. Mark occupied
holes (for example “I”) and empty holes (for example
“o”).
68. Twin Row Only (Air-Pro
®
and finger meter only):
Check for deliberate stagger (consistent difference
sprocket tooth orientation at the meter sprocket).
For the front row, note the tooth number at top dead
center. Record that number and the T.D.C. tooth
number for the rear row.

line shaft input sprocket, do not need to be
recorded. The clutch layout drawings show the
final locations of all collars.
