Figure 4.70: Auger Clearance
6.
Check clearance (C) between the feed auger flighting to
the pan.
•
If the feed auger is in the fixed position, clearance
should be between 24
–
28 mm (15/16
–
1 1/8 in.).
•
If the feed auger is in the floating position, clearance
should be between 11.5
–
15.5 mm (7/16
–
5/8 in.).
7.
If adjustment is required, loosen two nuts (B) and rotate
the auger to position the flighting over the feed pan.
8.
Turn bolt (A) clockwise to increase clearance (C); turn
bolt (A) counterclockwise to decrease clearance (C).
•
If the feed auger is in the fixed position, set clearance to
24
–
28 mm (15/16
–
1 1/8 in.).
•
If the feed auger is in the floating position, set clearance
to 11.5
–
15.5 mm (7/16
–
5/8 in.).
NOTE:
The clearance increases between 25
–
40 mm (1
–
1 1/2 in.)
when the center-link is fully retracted.
9.
Repeat Step
and Step
for the
opposite end of the auger.
IMPORTANT:
Adjusting one side of the auger can affect the other side.
Always double-check both sides of the auger after making
final adjustments.
10. Tighten nuts (B) on both ends of the feed auger. Torque the
nuts to 96 Nm (70 lbf·ft).
11. Rotate the feed auger and double-check clearances.
4.7.2
Checking Feed Auger Chain Tension
The auger is chain-driven by the float module drive system sprocket attached to the side of the auger.
There are two methods for checking the auger drive chain tension: the quick method is intended for frequent checks; the
thorough method is more accurate and should be used when replacing or reinstalling the chain.
Refer to the appropriate procedure for check auger chain tension:

Quick Method
The auger is chain-driven by the float module drive system sprocket attached to the side of the auger.
DANGER
To prevent injury or death from the unexpected start-up of the machine, always stop the engine and remove the key
from the ignition before leaving the operator
