10.9 AUGER
10.9.1 Auger Pan Clearance
Adapters are factory-set to the proper auger
clearances to the pan and feed draper.
It is important that these clearances are
maintained.
Too little clearance may result in the tines or
flighting contacting and damaging the draper or
feed pan under certain orientations of the header.
Look for evidence of contact when greasing the
adapter.
Should adjustment to the auger be necessary,
proceed as follows:
a. Extend center-link to maximum for steepest
header angle, and fully lower the header.
b. Check that adapter float linkage is on downstops
(washer (A) and nut (B) cannot be moved).
c. Loosen two nuts (C) and jam-nut (D).
d. Turn nut (E) clockwise to raise auger and
increase pan/draper clearance.
e. Repeat for other end of auger.
f. Check clearances, and re-adjust as required.
g. Tighten nuts (C,) and jam-nut (D) on both ends of
auger.
