Abstract: A lubrication system for a work tool, such as a demolition hammer, on a machine, such as an excavator or a loader. The lubrication system is mounted on drive line fluid connectors of the machine, such as hydraulic or pneumatic hoses. The lubrication system is fully supported by the connectors only and does not require mounting to the machine itself. The lubrication system includes a movable spool powered by the drive fluid of the machine, the spool reciprocating within a sleeve to force lubricant through passages to the work tool.

Abstract: A hydraulic hammer may include a power cell adapted to reciprocally drive a piston along an axis. The piston may, in turn, drive a hammer tool having a first end juxtaposed against the piston for accommodating cyclic impacts by the piston. While the first end of the hammer tool may be contained within a housing, the other end may extend from the housing for impacting rock, for example. The power cell and housing are axially secured together by a plurality of tie rods and nuts secured to ends of the tie rods, and the housing may include exterior pockets for accommodating the nuts. Each nut may have a circular exterior surface, and each nut pocket may have a generally elliptical interior surface, such that the exterior surface of each nut may be configured to engage at least two spaced apart areas of a corresponding interior surface of each nut pocket.
