ABSTRACT:
Pin retainers are normally used to secure a pin in its assembled so that one member can be releasably secured to another member, such as, securing a tooth to an adapter nose. Many times the pin retainer is not sufficiently strong to hold the pin in place under adverse operating conditions. Known pin retainers that are effective to hold the pin in place are not readily available and are expensive to produce. In the subject arrangement, a pin retainer assembly is provided which can be made from known components and is effective to hold a pin in place under adverse operating conditions. The pin retainer assembly includes a split retaining ring loosely sandwiched between at least two retaining members and held together by various known bonding or securing methods.
