This metal-rubber shock absorber dampens vibration and impact loads within the threshing mechanism of the parent combine. It is positioned between rigid structural members and the moving components of the threshing assembly, where it absorbs cyclic forces from the rotating drum and concave system. A worn or collapsed absorber allows excessive movement in the threshing unit, which can lead to uneven crop flow and accelerated wear on adjacent bearings and drive components. This original part is manufactured to match the original stiffness and damping characteristics of the assembly, so it maintains the correct clearance and load distribution without requiring shimming or modification. On installation, inspect the mounting brackets for distortion and replace any corroded fasteners.
