Fitting Rings

  1. Position rings near bottom of bore at a point where bore diameter is smallest. Ring must be square in bore. Measure ring end gap with a feeler gauge.
  2. Using a feeler gauge, check ring side clearance. Ensure rings turn freely in their ring grooves.
  3. When installing rings on piston, ensure gaps are correct. See Figure and Figure. Install compression rings with marking upward.
