ABSTRACT:
Apparatus and methods for the removal and installation of sleeve bearings in a camshaft bore of an engine, such as a diesel engine. The device includes an operator rod, a bearing puller in accordance with U.S. Pat. No. 4,624,041, for engaging and pulling and/or pushing a sleeve bearing in the camshaft bore, apparatus for coupling the bearing puller along a rear end portion of the rod and at selected positions along the length of the rod for engaging sleeve bearings along the camshaft bore to both pull the bearings out of operating position and to reinstall bearings in operating positions, and apparatus for coupling the rod with a front face of the engine during the pulling and pushing of sleeve bearings for removal and installation of the bearings. In some embodiments of the apparatus the rod is operated by a wrench driven nut to pull and/or push the rod. In other embodiments the rod is operated by a hydraulic jack having an open hole piston fitting on the rod. Methods are described for operating the apparatus to remove and install the sleeve bearings along the camshaft bore and at an end location with the engine either in or out of a frame.
