Claas - CL0006451030 - Metal Insert

This metal insert is a structural component for the cutterbar assembly of a grain harvester header. It provides a wear-resistant mounting point for the knife-drive components, maintaining the correct geometry between the reciprocating knife and the stationary ledger plates. Over time, the contact surfaces on the insert wear, allowing play that leads to increased vibration and uneven cutting. A worn insert causes the knife to drift out of alignment, resulting in ragged stubble and higher power draw. The original manufacturer machines the insert to the same hardness and dimensional tolerance as the original assembly, so no shimming or modification is needed during replacement.
