FEEDER CONVEYOR CHAIN ADJUSTMENT 

Refer to the Case IH® 5088/6088/7088 Operator’s Manual for instructions on 
adjusting the feeder conveyor chain tension. 
 

FEEDER CONVEYOR CHAIN FORE/AFT ADJUSTMENT 

The fore/aft position of the conveyor drum must be adjusted correctly to obtain correct 
feeding of material from the Header auger to the feeder. The position of the drum must 
be adjusted for a maximum clearance of (1) 38 mm (1-1/2 inch) from the conveyor 
chain slat (2) to the feeder face (3). 
 

Note:

  It may be necessary to add or remove chain to get the proper feeder drum 

position. 
 
 
 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

 
 

Important:  

Fully rotate the Header Adapter left and right after all adjustments 

of the feeder conveyor chain have been made to be sure there are no 
interference points.

  If not adjusted properly severe damage to the feeder 

conveyor chain may occur.
