Abstract
Disclosed is a digging implement (such as a dragline bucket) having a trunnion link connected to the implement by a pin secured in place by a retention device. Such device is coupled to the pin along the pin longitudinal axis. The pin has a first portion engaging the implement and having internal threads and the retention device has a stop member and an exteriorly-threaded stem extending therefrom. The stem is threaded to the internal threads of the first portion. Preferably, the stop member is recessed in a protective pocket which helps protect the retention device from damage otherwise caused by material being handled by the implement.
