ABSTRACT:
In many pinned connections between the frames of a machine such as an articulated construction machine, the forces passing through the pin connection caused flexing of the various bolted connections which ultimately could cause the loosening or failure of the bolts. The present invention provides a retainer member for a pin member that has a groove positioned in an engagement surface to divide the engagement surface into radial inner and outer portions. A plurality of fasteners are positioned in the radially inner engagement surface to secure the retainer member to the pin member. The radially outer engagement surface, having a reduced cross-section and no fasteners, is allowed to flex to accommodate the forces passing from one frame to the other, thus maintaining the integrity of the bolted connection.
