Check and Adjust Clearance Between Cleaning Auger and Staggered Belt Roll

TS698-UN-21SEP89

E41086-UN-04OCT96

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 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 OD	Clearance	1—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 cleaning auger flighting moves crop toward 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 auger and check for eccentricity.

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

8. Reconnect cleaning auger chain. (See Adjust Lower Drive Roll Chain in this section.)

2. Loosen the staggered shaft bolt (A) and roll bracket bolts (B) on the right and left-hand side of the baler.

3. At both ends of the staggered belt roll, put a 2 mm (0.078 in) shim between flighting and outside diameter of the staggered belt roll.

4. When tightening bolts, make sure that roll is free to rotate. Ensure a minimum gap of 1 mm (0.039 in) between the roll and hole in the side sheet.

   Hold roll firmly against shim and tighten all bolts.

5. Remove shims used in previous step.

6. Start tractor engine. Close gate, shut OFF tractor engine, and remove key.

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

   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.

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

9. Reconnect cleaning auger chain. Adjust chain idler. (See Adjust Lower Drive Roll Chain in this section.)
