BUCKET TOOTH LOCKING PIN

摘要

A system to attaching a tooth to a bucket shank comprises a ring seat in the shank having a cam. A locking ring having a corresponding cam is seated in the seat and has an interior channel bounded by shoulders. A locking pin of a dissimilar material to the ring includes a lobe sized to correspond to the channel. Once inserted through apertures in the tooth and the shank, the pin may be rotated to force the lobe over the shoulders and to be housed in the channel to securely hold the pin in place.
