Checking and Adjusting Clearance Between Cleaning Auger and Staggered Belt Roll (456S)

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

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

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

2. 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 bolts, make sure roll is free to rotate with a minimum gap of 1 mm (0.039 in.) between roll and hole in sidesheet.

3. Hold roll firmly against shim and tighten all bolts.

4. Remove shims.

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

6. 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.

Specification

7. Reconnect cleaning auger chain. Adjust chain idler. (See ADJUSTING LOWER BELT and CLEANING AUGER DRIVE ROLL CHAIN in this section.)
