    Abstract: A venting plug assembly for sealing a coolant channel and venting air therefrom is disclosed. The coolant channel defines an open portion to receive the venting plug assembly. The venting plug assembly includes an outer sealing element with an annular portion configured for sealing engagement with the open portion of the coolant channel. The venting assembly further includes an inner sealing element configured for sealing engagement with the annular portion of the outer sealing element. The inner sealing element is configured to move relative to the annular portion of the outer sealing element to allow air to vent from the coolant channel through the outer sealing element.

    Abstract: A method for repairing a cylinder liner includes: placing a cylinder liner having a first inner diameter and a first outer diameter into a cavity of a confinement, the cavity including a cavity inner diameter that is substantially the same as the first outer diameter of the cylinder liner; heating the cylinder liner to a temperature at which the cylinder liner undergoes plastic deformation, causing the first inner diameter of the cylinder liner to decrease; and cooling the cylinder liner. The cooled cylinder liner has a second inner diameter that is less than the first inner diameter. An apparatus for repairing a cylinder liner includes a confinement having a cavity and a fluid passageway for controlling the temperature of the confinement, and a heating block for heating the cylinder liner when the cylinder liner is inserted into the cavity.

    Abstract: A method of remanufacturing a rocker arm is provided. The rocker arm includes a body defining a center hole for receipt of a shaft, a first arm extending radially away from the center hole, and a second arm extending radially away from the center hole in a direction opposite the first arm. The second arm is configured to be operatively engaged with a valve mechanism and includes a contact surface configured to engage with a braking member. The contact surface includes a worn upper hardened surface. The method includes machining the contact surface to a depth less than a predefined tolerance limit to remove the worn upper hardened surface and create a generally planar unhardened contact surface. The method further includes hardening the unhardened contact surface using a laser to create a repaired contact surface with a surface hardness of greater than at least Rockwell C 50.
