Piston Ring and Connecting Rod
1. Remove the piston rings using a piston ring tool (Code No.
07909-32121 ).
2. Remove the piston pin (7), and separate the connecting rod (6)
from the piston (5).
(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.
• When installing the oil ring onto the piston, 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 connecting rod to the piston, immerse the
piston in 80°C (176 OF) oil for 10 to 15 minutes and insert the
piston pin to the piston.
• NOTE
• When installing the connecting rod to the piston, align the
mark (8) on the connecting rod to the arrow's direction of
casting mark (9) on the piston.
• Mark the same number on the connecting rod and the
piston so as not to change the combination.
