piston before pulling out the piston pin. Use care since the 
piston is hot after heating.

°C (158°F) and pull out the 

piston pin.

CAUTION

Apply ample coat of engine oil to the periphery of the pis-
ton pin and the hole of the connecting rod small end. The 
clearance between the piston and the piston pin is a tight 
fit at room temperature. Therefore, be sure to heat the pis-
ton before inserting the piston pin. Use care since the pis-
ton is hot after heating. 
3. Heat the piston to approximately 70

°C (158°F).

4. With the front mark of the connecting rod and that of the 

piston located on the same side, insert the piston pin.

5. Set the snap ring into the other side of the piston pin hole.

6. Check that the piston moves smoothly.

.

>>B<< OIL RING INSTALLATION
1. Fit the oil ring spacer into the piston ring groove.

NOTE: The side rails and spacer may be installed in either 
direction.
