SECTION 8. MAINTENANCE AND SERVICING
Form 169441 119 Revision B
8.9.1.2 Reel Clearance Adjustment
DANGER
Engage header lift cylinder stops before
working under header.
a. Raise header, engage header lift cylinder stops,
and lower header onto stops.
b. Lower the reel fully.
c. Adjust outside arms as follows:
1. Loosen bolt (A).
2. Turn cylinder rod (B) counter clockwise to
raise reel and increase clearance to
cutterbar, or clockwise to decrease.
3. Tighten bolt (A).
4. Repeat at opposite side.
d. For split reels (D60 only), adjust center arm as
follows:
1. Loosen nut (C), and turn nut (D) clockwise to
raise reel and increase clearance to
cutterbar, or counter clockwise to decrease.
2. Tighten nut (C).
8.9.2 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 adjustment compensates for
reel flexing.
The “frown” is adjusted by re-positioning the
hardware connecting reel finger tube arms to reel
discs.
IMPORTANT
The “frown” profile should be
measured prior to reel disassembly for
servicing so that the profile can be
maintained after re-assembly.
a. Position the reel over the cutterbar (4 - 5 on the
gauge). This position provides adequate
clearance at all reel fore-aft positions. Refer to
Section 7.12.9 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.
