Piston Ring and Connecting Rod

1. Remove the piston rings using a piston ring tool.

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 °F) oil for 10 to 15 minutes and insert the

piston pin to the piston.

• When installing the connecting rod to the piston, align the mark

(9) on the connecting rod to the fan-shaped concave (8).

IMPORTANT

• Mark the same number on the connecting rod and the

piston so as not to change the combination.
