Threshing Elements

1. IMPORTANT:

   
   H94732-UN-22SEP09

   A - Cap Screws

   B - Threaded Strap

   C - Threshing Element

   Rotor is a balanced assembly. Elements must be replaced in groups of three to maintain balance. When installing more than one kit, do not mix and match elements. Replacement kits are available through service parts and include cap screws with pre-applied Thread Lock and Sealer. Always use supplied cap screws. Elements that become loose may result in machine damage.

   Remove concave sections as needed to access threshing elements. (See Concave Sections—Remove and Install.)
