  • Method of remanufacturing a shell of a heat exchanger and a remanufactured shell
    Patent number: 9593893
    Abstract: A method of remanufacturing a shell of a heat exchanger is provided. The shell has an inner surface that defines an inner diameter thereof and the inner surface has a worn portion adjacent to an end of the shell. The method includes machining the inner surface to remove the worn portion and machining to form a tapered surface adjacent to the end of the shell. A diameter of the tapered surface increases progressively from the inner diameter of the shell to a maximum diameter at the end of the shell.
    Type: Grant
    Filed: September 11, 2014
    Date of Patent: March 14, 2017
    Assignee: Caterpillar Inc.
    Inventors: Eric R. Jeffery, John S. Miller, Jr.

  • Torque coefficient measuring device
    Patent number: 8490500
    Abstract: A torque coefficient measuring device can be used to measure an axial load produced by a torque applied to a threaded component which is mounted to the fixture. The measuring device can include a base defining a chamber therein. A load sensor is disposed within the chamber of the base. A movable load pin is housed within the base and arranged such that an axial load placed upon the load pin is transmitted to the load sensor. An attachment member is adapted to be connected with the threaded component. The attachment member is operably arranged with the load pin such that a torque applied to a threaded component mounted to the attachment member places an axial load upon the load pin.
