Check Piston Connection

  1. Before removing the piston, test the condition of the connecting rod opening, needle bearing, and wrist pin.
  2. Grip the connecting rod with one hand, and try to rock, not slide, the piston side to side.
  3. If there is any play in the piston connection, you already know something is out of spec.
  4. Remove the pin clips with a pick and safety glasses, because they might go flying.
  5. Assemble your wrist pin removal tool, and press the pin from of the cylinder.
  6. Remove the needle bearing, and wrap your connecting rod with a clean shop towel.
