CA 2556291

An apparatus for repairing steering knuckle (kingpin) bearings includes a table having multiple, adjustable slides for receiving and securing the steering knuckle to the table, a boring bar and cutter, two adjustable bearing supports for receiving and positioning the boring bar along an axis coincident with the axis of the kingpin bearings, a first drive assembly for advancing the boring bar and a second drive assembly for rotating the boring bar. A method of repairing a steering knuckle comprises securing the knuckle to the slides and the slides to the table, utilizing cylindrical centering rings to align the boring bar with the axis of the kingpin bearings, supporting and securing the boring bar on the previously established axis in a pair of bearing supports and rotating and feeding the boring bar and cutter to create new surfaces in the steering knuckle adapted to receive bearing sleeves. Upon installation of both bearing sleeves, the boring bar and drive unit are reinstalled and the inside diameter of the sleeve is bored to the proper size to receive the kingpin.
