SECTION 7 – SERVICE
Form 169149 Revision E 62
Auger Finger Components
7.8 REPLACING TEETH
WARNING: DO NOT begin to
perform any service procedure until
combine is lowered to the ground or
feeder house locks are engaged,
combine is shut off, the key is
removed and all moving parts have
stopped.
NOTE: It may be necessary to remove the
draper belt when replacing the teeth. Refer to
“Replacing Draper Belts” for instructions.
If any of the teeth break or wear down enough to
affect the performance of the machine, the tooth
should be replaced. Excessively worn teeth will
reduce picking efficiency resulting in losses far
exceeding the cost of new teeth.
a) Remove the 1/4 inch flange nut used to affix
the teeth to the finger belt.
b) Remove the tooth and replace.
c) Tighten the 1/4 inch flange nut. The nut
should be tightened just so that the tooth
cannot be moved by hand.
