7.11.5 Auger Pans
The high density polyethylene auger pans are
repairable and replaceable. Refer to the
Technical Service Manual, MacDon Form
169048 for details on replacing the pans.
IMPORTANT
To prolong the life of the auger pan, be
sure to check that reel tines do not contact
the pans when adjusting the reel position
or tine pitch.
Stones and other debris can deform the
polyethylene pans. If this occurs, the pans can
be straightened as follows:
CAUTION
To avoid personal injury, before servicing
header/mower conditioner or opening drive
covers, follow procedures in Section 7.1
PREPARATION FOR SERVICING, and
Section 7.2 RECOMMENDED SAFETY
PROCEDURES.
a. Heat the deformed area with a heat gun until the
poly is almost sticky.
b. Push out the dent, and then apply a cold wet
rag. Keep wetting the rag in cold water, and
applying it on the area until cool. This ensures
the poly retains its shape.
NOTE
If the dent is too severe, and has
stretched the poly, it may be necessary
to locally remove the poly. Use a plastic
welder to rejoin the material.
Replacement pans are also available
from your Dealer.

Rubber fingers should be replaced if missing or
damaged.
