7.11.5.2 Replacing Stripper Bar
WARNING
To avoid bodily injury or death from
unexpected start-up or fall of raised
machine, stop engine, remove key, and
engage lift cylinder stops before going
under machine.
a. Remove four nuts and bolts (A) that secure each
stripper bar (B) (LH and RH) to the pan, and
remove bars. There are six bars in total.
b. Position new bars (B) on pan as shown, with
upper flange on front bar facing forward.
c. Install three bolts and nuts (A) in each bar, and
torque to 150 ft·lbf (203 N·m).
d. Check clearance between auger and
stripper bars.
e. Loosen bolts (A), and add shims between
stripper bars and pan at bolt locations as
required to obtain clearance as shown.
f. Retighten bolts to specified torque.
7.11.5.3 Front Stripper Bar Extensions
Extensions for the front stripper bar are provided
for installation (if required for certain crop
conditions), or especially in tall crops that cause
material to bunch up at the ends of the
conditioner rolls.
Stripper bar extensions will allow the auger to
carry the crop more towards the center, rather
than prematurely feeding it to the conditioner.
a. Raise header, and engage lift cylinder stops.
b. Remove nuts and carriage bolts (C) securing the
two extensions (D) to underside of header pan
support, and retain for reinstallation.
c. Position extension (D) at inboard end of front
stripper bars (E), and mark locations of the two
holes onto the plastic pan.
d. Drill two 5/16 in. (8 mm) holes at these locations.
e. Install extension with carriage bolts (C) removed
at sub-step b.
f. Repeat above steps for other extension.
