ABSTRACT:
An adapter for permitting non-standard work tools to be attached to a work machine for which they were not originally sized to fit. The adapter comprises a sleeve which fits into bores on the work machine. Pins for attaching the work tool to the machine in turn are inserted through the work tool and into the sleeves. The sleeves protect the joint through seals positioned both on an outer surface of a flange of the sleeve, and on an inner surface of the bore of the sleeve. The sleeves also include holes for permitting lubricant to pass from the sleeve's outer circumferential surface to its inner circumferential surface. The sleeves may be permitted to rotate relative to the work machine via bearings in the bores of the work machine.
