A weld on adapter for the E330/E340 tooth family on 40 to 50 ton machines. The 6I6464 is often replaced together with a full tooth set, because a worn nose is what makes new teeth feel loose after a few shifts.
Seat and pin bore are machined in a single setup, so the tooth sits flat and the load path runs through the full contact face.
