Figure 5.51: Auger Clearance
6. Loosen two nuts (B).
7. Turn bolt (A) clockwise to increase clearance (C); turn
bolt counterclockwise to decrease clearance.
• If feed auger is in rigid position, set clearance to
22–26 mm (7/8–1.0 in.).
• If feed auger is in floating position, set clearance to
11–15 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.
8. Repeat Steps 6, page 421 and 7, page 421 for the
opposite end of the auger.
IMPORTANT:
Adjusting one side of the auger can affect the other side
so recheck both sides after final adjustment is made.
9. Tighten nuts (B) on both ends of the feed auger. Torque
the nuts to 93–99 Nm (68–73 lbf·ft).
5.7.2 Checking Auger Drive Chain Tension
The auger is chain-driven by the float module drive system sprocket attached to the side of the auger.
