3. Engine > Cylinders and Pistons
Clean off the cylinder mating surface, but take care to keep debris from
falling into the crankcase.
Spread the piston rings and lift them off opposite the gap.
Spread the rings the minimum amount during removal. The
rings can be easily damaged.
The two upper rings are each a single piece of metal. The oil ring
consists of an expander ring and two side rails.
