5. PISTON RING INSTALLATION
① The Oil Rings spacer is built into the piston-ring
groove.
② The side rail of the oil ring is built in an upper &
lower order. Position a part of the side rail in the
Piston ditch, hold it in place with your finger & fit it.
Do not install with the Piston Ring Expander
as the ring side will be damaged.
③ Install the Second Ring and Top Ring with the
Piston Ring Expander.
Position the clock mark side of the ring up.
