Adjusting Slip Clutches

Slip clutches protect the corn head drives. Each row unit drive and auger drive has a slip clutch.

All slip clutches are properly adjusted at the factory. The only time slip clutches will require adjusting is when they are disassembled for service. The length of the row unit slip clutch spring (A), when correctly adjusted, must be 66 mm (2-5/8-in.). The auger drive slip clutch is not adjustable.

IMPORTANT: Do not tighten nuts to the point where the clutch will not slip. The two nuts used to compress the spring must be jammed together. Torque to specifications. Grease thrust washer but do not grease clutch facings.

NOTE: The 1293 cross augers are driven from both sides.
