10.15.3 Wing Linkage Adjustment
WARNING
Stop combine engine, and remove key before
making adjustments to machine. A child or
even a pet could engage the drive.
If the wing vertical movement up or down is not
equal, adjust the wing linkage as follows, referring
to following illustrations:
a. Check that the cutterbar is straight when wings
are in LOCK mode.
b. Set cutterbar approximately 6 in. (150 mm) off the
ground.
c. Remove linkage cover. Refer to Section 10.4.2
Linkage Cover (FD70 FLEXDRAPER ONLY).
d. With cutterbar straight, check that the following
two conditions exist:
Condition 1: Bottom edge of bellcrank (A) is
parallel to the bottom edge of the center-link (B).
Condition 2: The top of the balance link (C) is
lined up with the white decal strip (D) within ½ in.
(12 mm).
NOTE
If decal is missing, check that the
dimension
is 3.1 +/- 0.5 in.
(80 +/- 12 mm).
e. If above conditions do not exist, perform the
following adjustments.
Condition 1: Unlock nuts (E), and turn bolt (F)
until edges are parallel. Lock nuts (E).
Condition 2: Unlock jam-nut (G) and turn
compression link (H) until balance link (C) and
decal (D) are lined up, or the dimension is met.
Lock the nut (G).
NOTE
One adjustment may correct both
conditions.
For example, if the bell- crank lower
edge (A) points down, and top of
balance link (C) is too low, adjusting the
center-link bolt (F) will also improve the
alignment of balance link (C) with decal
strip (D).
f. Replace linkage cover.
