Piston Replacement Inspection

    NOTE:
    • Cylinder bore must be within specifications for taper and out-of-round before fitting a piston.
  1. Select a piston size based on the cylinder bore.
  2. Choose the piston with the proper paint color.
    • Red - in the lower third of the size range.
    • Blue - in the middle third of the size range.
    • Yellow - in the upper third of the size range.
      NOTE:
      • For precision fit, new pistons are divided into three categories within each size range based on their relative position within the range. A paint spot on the new pistons indicates the position within the size range.
