  • Patent number: 4589180
    Abstract: To service an engine, it is frequently determined that a cylinder liner and piston must be replaced. Removal is difficult and time consuming if the piston is first removed through the liner and the liner is then grasped from below and pulled from the block. A method includes inserting a tool into a bore of the liner and expanding the tool into a frictional fit against the liner. A force is applied on the tool to forcibly move the liner. The piston and associated rings and rod are held in place in the liner by a partial vacuum for removal with the liner as a complete unit.

  • Patent number: 4574447
    Abstract: A body having parallel, flat ends and a through bore of a conical configuration is placed with the small end of the conical bore against and in alignment with a socket. The bushing, having an elastomer on its exterior, is placed with its end in the upper end of the body bore. A bolt head abuts the end of the bushing. The bolt passes through the bushing, the body and the socket. When a nut threaded on the bolt is turned, the bushing is pulled through the body and is subjected to tension and elongation. This reduces the diameter of the elastomeric part of the bushing to fit into the socket. The parts effecting the tensioning are then removed from the socket and bushing. The bushed socket can be placed into service.

  • Patent number: 4507838
    Abstract: A tool for removing and replacing automobile wheelbearings without removing either the axle or the bearing housing and without applying pressure to the axle. A frame is provided which is adapted to be secured to the bearing housing. An extractor is movably connected to the frame to travel between an advanced and retracted position. When the frame is secured to the bearing housing, the advanced position of the extractor places it in the bearing housing between the axle and the central opening of the bearing, with the end of the extractor being past the bearing. The end of the extractor is operable between an expanded and retracted state. In its expanded state, the end of the extractor cannot be moved through the central opening of the bearing and thus moving the extractor to its retracted position while it is expanded will draw the bearing out of the housing.

  • Patent number: 4361944
    Abstract: An extractor for the flanged tubular ferrule which surrounds the head of the barrel lock of a kilowatt-hour meter comprises an actuating screw and a two-piece clamp. The clamp has a threaded hole and two recesses of different diameters, the larger of which is adapted to fit around the flange of the ferrule and the smaller of which is adapted to fit around the body of the ferrule. To remove the ferrule, the two pieces of the clamp are fitted over the ferrule and then fastened together by bolts. Then the actuating screw is screwed into the clamp until the inner end of the screw abuts against the head of the barrel lock which is inside the tubular ferrule. Continued rotation of the actuating screw in a tightening direction causes the clamp to move outwardly on the threads of the screw and in so doing the captive ferrule is pulled out of the cover housing. Following removal of the ferrule, the barrel lock itself may be removed by a barrel lock extractor, preferably of the type described in my U.S. Pat. No.
