• Connecting rod front mark (C)
• Cylinder No. (D)
CAUTION:
Do not reuse snap rings.
b. Install the piston to the connecting rod. • Heat the piston until the piston pin can be pushed in by handwithout excess force [approx. 60 ° - 70 °C (140 ° to 158 °F)].
From the front to the rear, insert the piston pin into the piston
and through the connecting rod.
WARNING:
Pistons contain heat. When wo rking, wear protective equip-
ment to avoid getting burned.
• Assemble so that the piston front mark (B) on the crown and

c. Install the snap ring into the front of the piston pin-groove.
• After installing, check that the connecting rod pivots smoothlyon the pin.
CAUTION:
Do not reuse snap rings.
11. Using a piston ring expander, install the piston rings. CAUTION:
• Be careful not to damage the piston.
• When the piston rings are not replaced, remount the rings
in their original positions.
• When replacing the piston ri ngs, those without stamped
surface (A) can be mounted either side up.
• Install the second ring with the stamped surface (B) facing upward. If the ring is not stamped it can face in either
direction.
• Position each ring with the gap as shown, referring to the pis- ton front mark.
12. Install the connecting rod bearings to the connecting rod and the connecting rod cap.
• When installing the connecting rod bearings, apply engine oil to the bearing surface (crankshaft side). Do not apply oil to the
back surface (connecting rod and cap side), but thoroughly
clean it.
• When installing, align the connecting rod bearing protrusion
with the notch of the connecting rod to install.
