Fitting Pistons

Check ring clearance in grooves. Measure piston thrust face at bottom of skirt. Take cylinder bore measurements at several different depths. If clearance is excessive replace piston. Pistons come as piston/connecting rod assemblies only.

Check end gap of rings by placing ring in cylinder and using a piston to position ring. If end gap is to close file ends of ring to specifications. If end gap exceeds specifications install a larger ring. Chrome plated compression ring goes in top groove and stepped ring goes in second groove with step facing downward.
