10.14.2 Reel Clearance to Cutterbar: FD70
The finger to guard/cutterbar clearance with reels

(3 mm) measured at both ends of each reel,
and at the cutterbar flex locations with the
header in ‘full frown’ mode.
10.14.2.1 Clearance Measurement: FD70
CAUTION
Engage header lift cylinder stops before
working under header.
a. Raise header, and place two 6 in. (150 mm)
blocks just inboard of wing flex points.

frown’ mode.
c. Adjust fore-aft reel position so that back end of
cam disc is approximately between 4 and 5 on
the arm decal.
d. Measure clearance at ends of each reel.
NOTE
The reel has been adjusted at the
factory to provide more clearance at the
center of the reel than at the ends
(frown) to compensate for reel flexing.
e. Measure the clearance at both flex locations.
