3.12.7 Driveline
The driveline connects the header’s chain drive to the combine’s feeder house. Follow these procedures to maximize the
life of the driveline.
Clutch
The header-to-combine driveline contains a radial pin clutch that provides protection against overload. When the auger
encounters an obstruction, an overload occurs and the clutch slips while making a rattling sound and pulsating action.
Frequent slippage of more than 2 or 3 seconds may result in clutch damage.

IMPORTANT:
Prolonged operation of the header with the clutch slipping will
cause damage to the header and/or clutch.
If clutch is damaged, it must be replaced. Refer to Replacing
Driveline Clutch, page 228 for instructions.
Driveline Guard
The driveline guard protects the driveline from dust and dirt.
DANGER
To avoid serious injury or death, do NOT operate the machine if the guard is missing.
