Fitting Rings

  1. Push a ring into cylinder bore approximately 3/4" from bottom of bore. Ring must be square in bore. Using a feeler gauge, measure ring end gap. Compare measurement with specifications.
  2. Install rings onto piston. Both compression rings are chamfered. Note that top compression ring has two 30° chamfers on outer edge. Second compression ring's outer edge is slightly chamfered. Using a feeler gauge, measure ring side clearance between ring and ring land.
  3. If ring lands have high steps or are excessively worn, replace piston. Properly space ring end gaps on piston. See Fig 1 . Make sure no end gaps are in line with piston pin or thrust face of piston. Install rings with manufacturer's marking facing upward.
    NOTE: Top compression ring is identified by two 30° chamfers on outer edge.
