______________________________________
[1]: Piston ring end gaps are checked with the piston rings inserted approximately 15 mm (5/8 in.) from the bottom of the cylinder.
[2]: Piston ring grooves should be thoroughly cleaned before checking ring side clearance. Measure each ring in its original groove.
