ABSTRACT:
A one-piece locking pin (100) for use captively retaining a tooth (14) on an adapter portion (12) of an excavating tooth and adapter assembly has a primary wedge member (110) with an integral spring (120) extending upward from the member's distal end (116). A first positive stop member (130) extends from the wedge member (110) while an opposing second positive stop member (122) extends from the integral spring (12). After insertion, the locking pin (100) prevents separation of tooth (14) from adapter portion (12) while the first and second positive stop member (130, 122) prevent accidental loss of the locking pin (100) from the assembly. To remove the locking pin, a force sufficient to separate the first positive stop member (130) from the pin (100) is exerted to drive the pin (100) from the assembly.
