The resilient foot has a rubber tubular member to provide a resilient support and an insert of solid material within the tubular member to limit the travel of the resilient foot under load. The insert is disposed in a bore of the tubular member and is inwardly spaced a small distance from the support surface of the tubular member to limit the vertical motion. The resilient foot has an enlarged elastomeric flange to provide non-slip characteristics and radial grooves are provided in the flange for the squeezing out of fluid between the foot and a mounting surface.

An anchor bolt machining apparatus including an anchor bolt machining die and a die holder. The anchor bolt machining die includes a first head portion for fixing an anchor bolt and a first body portion receiving a screw machining die and the die holder includes a second head portion coupled to a rotational force supply device, a support portion coupled to the anchor bolt machining die, and a second body portion connecting the second head portion and the support portion.

A damping bearing (20) including an inner ball portion (34) attached to an end of a support shaft (32), and an outer collar portion (30) attached to a housing (22) for rotation of the housing relative to the support shaft about a center point. A chamber (28) for a damping fluid such as grease is defined by clearance between the end of the shaft and the housing. The fluid chamber has opposed bounding surfaces (29, 37) that are non-spherical about the center of rotation so that the chamber changes shape upon rotation of the bearing, thus shifting damping fluid across the chamber. The chamber may be a flat cylindrical void normal to a centerline (33) of the shaft. It may provide only enough clearance for less than ±10 of relative rotation between the housing and shaft. A set-screw (26) may pressurize the fluid in the chamber.

A genset chassis for mounting a genset includes an engine and generator thereon includes a pair of inner beams and an outer beam coupled to an outer sidewall of a corresponding inner beam. The outer beams are vertically offset from the corresponding inner beam such that at least a portion of the outer beams is higher than a corresponding inner beam. The outer beams are structured to be positioned on mounting members positioned on a surface so that a first distance between the at least a pair of inner beams and the surface is less than a second distance between the plurality of outer beams and the surface. The inner beams are structured to mount at least a portion of the genset thereon such that a part of the at least a portion of the genset is lower than the plurality of outer beams.

An internal combustion engine to electric motor conversion system for a work machine is provided. The electric motor conversion system is sized to substantially conform to a footprint of the internal combustion engine on the work machine. The electric motor conversion system includes an electric motor, a power distribution unit and a connecting bracket. The electric motor is configured for direct mounting on a frame of the work machine. The power distribution unit is separate from and positioned atop the electric motor. The power distribution unit controls operation of the electric motor. The connecting bracket is separate from the electric motor and power distribution unit. The connecting bracket includes a base, first attachment elements extending from a lower surface of the base for attachment to the electric motor, and second attachment elements extending from an upper surface of the base for attachment to the power distribution unit.
