7.11.3 Auger Pans
The high density polyethylene auger pans are
repairable and replaceable. Refer to the
technical manual, MD Part #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.
7.11.4 Rubber Fingers
Rubber fingers should be replaced if missing
or damaged.
a. Remove nut and bolt (A), and remove finger (B).
b. Position new finger in holder, and install bolt and
nut. Rubber finger should be free to move after
bolt is tightened.
7.11.5 Stripper Bars
To maintain proper clearance between auger
and stripper bars, bars may need replacing due
to wear or damage. Shims may also need to be
installed to compensate for local irregularities in
the structure.
If after adjusting stripper bars, auger position
needs to be adjusted, refer to Section 6.17.4
Auger Position.
WARNING
To avoid bodily injury or death from
unexpected start-up or fall of raised
machine, stop engine, remove key, and
engage lift cylinder stops before going
under machine.
7.11.5.1 Removing Stripper Bar
Heavy crops may cause plugging across the
auger due to restricted flow at the stripper bars.
Remove the lower stripper bar, and if necessary,
remove the center stripper bar as follows:
a. Remove bolts attaching stripper bar to pan.
b. Remove stripper bar.
c. Replace bolts in pan.
NOTE
Special countersunk bolts are available
