10.14.3 Reel Frown Adjustment
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.
The ‘frown’ is adjusted by re-positioning the
hardware connecting reel finger tube arms to reel
discs. The frown adjustment compensates for
reel flexing.
IMPORTANT
The ‘frown’ profile should be measured
prior to reel disassembly for servicing
so that the profile can be maintained
after reassembly.
a. Position the reel over the cutterbar (4 - 5 on
gauge). This position provides adequate
clearance at all reel fore-aft positions. Refer to
Section 9.11.10 Reel Fore-Aft Position.
b. Take a measurement at each reel disc location
for each reel tube.
c. Adjust the profile as follows: Start with the reel
disc set closest to center of header, and
proceed to the ends.
1. Remove bolts (A).
2. Loosen bolt (B), and adjust arm (C) until
desired measurement is obtained between
reel tube and cutterbar.
NOTE
Allow the reel tubes to find a
natural curve and position the
hardware appropriately.
3. Re-install bolts (A) in aligned holes, and
tighten.
10.14.4 Reel Centering
10.14.4.1 Double Reel Header
The reels should be centered between the
endsheets.
a. Loosen bolt (D) on each brace (E).
b. Move forward end of reel center support arm (F)
laterally as required to center both reels.
c. Tighten bolts (D), and torque to 265 ft·lbf
(359 N·m).
10.14.4.2 Single Reel Header
The reel should be centered between the
endsheets.
a. Loosen bolt (G) on brace (H) at both ends of reel.
b. Move forward end of reel support arm (J) laterally
as required to center reel.
c. Tighten bolts (G), and torque to 265 ft·lbf
(359 N·m).
