ABSTRACT:
In the pinned connections between frame members of articulated machines, it is typical to utilize one or more pin assemblies that have one or more spaces between the various components in the pin assembly. The present invention comprehends a pin assembly 10 that utilizes a first plurality of fasteners 82 to secure a first lock plate 72 to one of a pair of frame members 12 and 18. A first shim assembly 86 is included to remove any space between components along a first path of force transfer. A second plurality of fasteners 92 is utilized to mount a second lock plate 90 to a pin member 44. A second shim assembly 94 is included to remove any space between components along a second path of force transfer. The fasteners 82 and 92 work in conjunction with one another to greatly reduce flexing, and thereby the tendency for the fasteners to loosen, that occurs in a pin assembly 10 due to the transfer of forces therethrough.
