A - Cleaning Auger

B - Staggered Belt Roll

Shield removed for illustration purposes.

The cleaning auger (A) must operate close to the staggered belt roll (B) and belts to function correctly.

Clearance between the auger flighting and outside diameter of the staggered belt roll must be within specifications with gate fully closed and belts tensioned.
Auger Flighting-to-Staggered Belt Roll ODClearance1—3 mm (1/32—1/8 in)


Check Clearance

  1. Start tractor engine.

  2. Raise gate, shut OFF tractor engine, and remove key.

  3. Lock the gate.

  4. Disconnect cleaning auger drive chain.

  5. Remove any crop or mud buildup on roll.

  6. To reduce the risk of fire, verify that the cleaning auger flighting moves crop toward the center of baler when top of auger rotates forward.

    Check clearance with a feeler gauge at both ends and in the middle of the baler. Rotate the auger and check for eccentricity.

  7. Verify that the cleaning auger flighting moves crop toward the center of baler when top of auger rotates forward.

  8. Reconnect cleaning auger chain. (See ADJUST LOWER DRIVE ROLL CHAIN in this section.)


Adjust Clearance

  1. E41085
    E41085-UN-04OCT96

    Right-Hand Side Shown

    A - Roll Shaft Cap Screw

    B - Roll Bracket Nuts

    Remove cleaning auger chain.


  2. Loosen cap screw (A) and nuts (B) on the right-hand and left-hand side of the baler.

  3. Place a 2 mm (0.078 in) shim between the flighting and the outside diameter of the belt roll at both ends.

  4. When tightening mounting hardware, make sure that the roll rotates freely with a minimum gap of 1 mm (0.039 in) between the roll and the hole in the side sheet.

    Hold the roll firmly against shim and tighten all mounting hardware.

  5. Remove shims used in previous step.

  6. Start the tractor engine and close the gate. Shut OFF the tractor engine and remove key.

  7. Manually rotate the auger. Check clearance between roll and auger flighting near both side sheets and at a center location. Clearance must be within specifications. If not, reposition the roller or check straightness of cleaning auger.
