from the piston (2).
(When reassembling)
• When installing the rings, assemble the rings so that the
manufacturer's mark (12) near the gap faces the top of the
piston (2).
• When installing the oil ring (6) onto the piston (2), place the
expander joint (10) on the opposite side of the oil ring gap (11).
• Apply engine oil to the piston pin.
• When installing the piston pin (1), immerse the piston (2) in
80 °C (176 °F) oil for 10 to 15 minutes and insert the piston pin
