ABSTRACT:
The present invention is a pin assembly used with a quick coupling device for attaching a work implement to a machine. The pin assembly has a pair of pins each circumferentially surrounded by a bushing which has a pair of seals therein. The seals are positioned between the inner surface of the bushing and an outer surface of the pins for retention of lubricating fluid across a portion of the pins during operation to limit pin wear.
