  • Publication number: 20150226251
    Abstract: The present disclosure is related to an assembly for coupling a first member and a second member. The first member includes a lower portion defining a hole having a central axis therethrough. The second member includes an upper portion having a mounting aperture and an access aperture. Further, the assembly includes an elongate fastener configured to be at least partially received in the hole and the mounting aperture. The assembly also includes a fastening member having a nut and a tab. The nut and the elongate member are aligned with the central axis and threadingly coupled to each other. The tab engages with the walls of the access aperture to prevent rotation of the nut during coupling. The tab also projects through the access aperture when the nut is aligned with the central axis.

  • Patent number: 8602511
    Abstract: A method of retrofitting a generator set includes disconnecting a removable panel from a frame of a generator set housing. In order to accomplish this, short bolts associated with the removable panel are disconnected from nutserts that are permanently affixed to the frame. A removable panel compliance kit is installed to the generator set frame by threading long bolts through the nutserts and then attaching a pair of nuts in a locking configuration on each of the long bolts. The removable panel, which is modified to include keyhole shaped bolt openings, is then reconnected to the frame by advancing the long bolts further into the respective nutserts.

  • Patent number: 8275192
    Abstract: An apparatus for axially aligning a first coupling member and a second coupling member that can be connected so as to form a rotating assembly. The apparatus includes a measurement arrangement configured to be mounted onto the first coupling member and to be rotated therewith. The measurement arrangement includes an emitter arrangement configured to emit first and second signals in the direction of the second coupling member so as to cause at least a portion of said first and second signals to be reflected by the second coupling member. The measurement apparatus further has a capture arrangement configured to capture at least a portion of the first and second reflected signals. The apparatus includes a control arrangement configured to determine an offset in axial alignment between the first and second coupling member based on at least the first and second reflected signals.

  • Publication number: 20120137516
    Abstract: A cooling system for an engine is disclosed. The cooling system may have an engine, a pump configured to receive coolant from the engine and generate a flow of coolant, and a heat exchanger configured to receive the coolant flow. The cooling system may also have a plurality of orifice plates located between the pump and the heat exchanger. At least one of the plurality of orifice plates may be adjustable to control the flow of the coolant from the engine to the heat exchanger.
