    Abstract: A parking pawl assembly having a housing, a parking pawl having a pin bore, a support sleeve fitted in the pin bore, and a pivot pin inserted through the support sleeve. The pivot pin is attached to the housing, thus pivotally attaching the parking pawl to the housing. The parking pawl includes a first end and a second end spaced from the first end. The first end defines the pin bore having an interior bore surface. The support sleeve includes an exterior surface fitted to the interior bore surface of the parking pawl. The exterior surface of the support sleeve may include outer diameter rolled threads or other locking features. The interior bore surface of the parking pawl may include inner diameter rolled threads operable to receive the outer diameter rolled threads of the support sleeve.

    CPC classification number: B23P6/04

    Abstract: A method of repairing an ultra-large single-piece cast component of a vehicle body. The method includes the steps of locating a damaged portion of the cast component, determining an extent of the damaged portion of the ultra-large cast component, defining a cut-line sectioning off the damaged portion from an undamaged portion of the ultra-large cast component, cutting along the cut-line to excise the damaged portion from the undamaged portion of the ultra-large cast component, and joining a replacement piece to the undamaged portion of the ultra-large cast component. The replacement piece is fabricated based on the original manufacturer’s geometry and dimensional data of the excised damaged portion. The undamaged portion of the ultra-large cast component remains on the vehicle body during the repair.

    Abstract: An engine for a vehicle. The engine includes a cast engine block having a hybrid insert disposed in a fastener bore having rolled internal threads. The hybrid insert includes an internal surface having cut inner diameter (ID) threads and an external surface having rolled outer diameter (OD) threads. The rolled OD threads of the hybrid insert are received in the rolled internal threads of the fastener bore. The hybrid threaded insert may include a bi-metal in which the ID threads are formed of one metal alloy and the OD threads are formed of another metal alloy. Alternatively, the external surface of the hybrid insert may define locking features and the engine block is cast onto these locking features, thereby locking the hybrid insert to the engine block.
