4.16.1 neuTRal dRive ShafT
The neutral drive shaft is available for double drive headers. The
neutral shaft is used to bypass the fan when harvesting conditions
do not require air.
Use six 3/8” x 1” carriage bolts, flat washers and nylock nuts 1.
to install the stub shaft, two bearings and four flangettes to
the gearbox mount assembly (Figure 28). The hex end of
the shaft should point toward the right side of the header.
Torque 3/8” hardware to 30 ft-lbs.
Make sure the stub shaft is centered in the gearbox mount 2.
assembly and tighten the lock collar on each bearing. To do
so, insert a punch in the lock collar dimple. Using a hammer,
tap the punch in the direction of normal shaft rotation until the
collar is tight. Then, tighten the lock collar set screw.
