Checking and Adjusting Clearance Between Cleaning Auger and Staggered Belt Roll (468S)

causym CAUTION: Make sure gate is in the raised position and locked. If gate is not raised and locked while performing this procedure, the gate could close suddenly causing injury or death.

NOTE: 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 staggered belt roll should be within specifications with gate fully closed and belts tensioned.

Specification

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.

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

6. 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.

Adjust Clearance

1. Remove cleaning auger chain.

2. Loosen staggered belt roll shaft cap screw (A) and roll bracket nuts (B) on right and left-hand side of baler.

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

IMPORTANT: When tightening mounting hardware, make sure roll is free to rotate with a minimum gap of 1 mm (0.039 in.) between roll and hole in sidesheet.

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

5. Remove shims used in previous step.

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

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

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