Definitions

  • a disadvantage of this practice is that the piston must first be removed through the top of the associated cylinder liner so that the tool may be inserted in the liner. Performing these individual steps is inconvenient and time consuming, particularly where carbon build-up or wear step is pronounced and must first be removed by finding in order to the slide the piston out of the bore.
  • the tool 12 of Figs. 3 and 4 is shown in Figs. 1 and 2 to, as later described, illustrate removal from the engine 10 of a unit 58 defined to include the cylinder liner 16, piston 26, rings 28 and rod 32 assembled together in their operational relationship.
