Abstract:
The present disclosure relates to a method for inspecting worn surface of camshaft lobes of a camshaft. The method includes providing a laser scanning device at a predetermined distance from the worn surface of the camshaft lobes, the laser scanning device being configured to scan and gather data. The method includes moving the laser scanning device along a reference axis parallel with an axis of rotation of the camshaft and repeating the scanning for each camshaft lobe of the camshaft. The method includes generating a set of data points for each camshaft lobe. The method further includes determining a maximum depth of the worn surface based on the set of data points. The method also includes selecting the camshaft lobes for a remanufacturing process, if the maximum depth of the worn surface for each measured camshaft lobe is less than or equal to a predefined tolerance limit.
Abstract:
A method of remanufacturing a rocker arm having a body defining a contact surface is provided. The contact surface is configured to engage with a braking member and having a worn portion thereon. The method includes machining the contact surface to remove the worn portion and to form an opening configured to receive an insert member therein. The insert member includes an upper surface configured to engage with the braking member. The method further includes coupling the insert member to the opening.
Abstract:
A method of remanufacturing an engine block is provided. An insert is removed from a recess in a top deck of the engine block that surrounds a cylinder bore in the engine block. A used cylinder liner is removed from the cylinder bore. The used cylinder liner has a flange on an upper edge thereof having a first thickness. The recess in the top deck of the engine block is cleaned. A replacement cylinder liner is positioned in the cylinder bore. The replacement cylinder liner has a flange on an upper edge thereof that is received in the cleaned recess. The flange of the replacement cylinder liner has a second thickness that corresponds to the sum of the first thickness and the depth of the cleaned recess.
Abstract:
A tool for removing a piston ring from a piston is provided. The tool includes a handle portion, an elongate portion, and a working portion. The elongate portion defines a longitudinal axis. The working portion includes a first section and a second section coupled to the first section at a pivot region. The first section is coupled to the elongate portion and is inclined at a first angle relative to the longitudinal axis. A retaining member protrudes from the first section. The second section includes a leading edge. A thickness of the second section decreases continuously from the pivot region to the leading edge and a width of the second section increases continuously from the pivot region to the leading edge. The working portion includes a ramp member extending from an upper surface of the second section. The ramp member includes an engaging surface to engage a piston ring.
