(When reassembling)
• When installing the ring, assemble the rings so that the
manufacturer's mark (12) near the gap faces the top of the piston
(2).

expander joint (10) on the opposite side of the oil ring gap (11).
• Apply engine oil to the piston pin.
• When installing the connecting rod (7) to the piston (2), immerse
the piston (2) in 80 °C (176 °F) oil for 10 to 15 minutes and insert
