8.8 AUGER
8.8.1 Auger Pan Clearance
Adapters are factory-set to the proper auger
clearances to the pan and feed draper.
IMPORTANT
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).
d. Turn bolt head (D) 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) on both ends of auger.
