Threshing Tines, Spike Teeth and Separator Tines—Remove and Install

1. IMPORTANT: Rotor is a balanced assembly. Elements and tines must be replaced in sets of three to maintain balance. Replacement kits are available through service parts and include new cap screws with pre-applied Threadlock and Sealer. Tines or elements that become loose may result in machine damage.

   If tines or elements need to be removed for other than replacement, mark location on tine(s)/element(s) and rotor, prior to removal. Install in same location as removed to maintain balance. Always use new cap screws.

   Make sure to clean out tailings and front cross auger if tine replacement is due to broken or damage tines. Failure to do so before initial start-up may allow broken tines to recirculate and cause tine damage to reoccur.

   NOTE: The concave leveling procedure and zeroing is necessary each threshing elements change or when removed and installed the concave. (See Concave Leveling section.)

5. If one element or tine needs replaced, replace all in the group. Example: If element 2 needs to be replaced, replace elements 1 and 3 also.

6. Use Threshing Elements and Separator Tine Location diagram for identifying elements and tines.
