PISTON AND PISTON RING INSTALLATION

Install the piston and piston ring in the reverse order of removal.
Pay attention to the following points:
PISTON RING
• Install the piston rings in the order of oil ring and 1st ring.
• The first member to go into the oil ring groove is a spacer 1.
After placing the spacer, fit the two side rails 2.
NOTE:
Side designations, top and bottom, are not applied to the spacer
and side rails: you can position each either way.
When installing the spacer 1, be careful not to allow
its two ends to overlap in the groove.
• Be sure to bring the concave side of 1st ring to the top when
fitting it to the piston.
• Position the gaps of the two ring as shown. Before inserting a
piston into the cylinder, check that the gaps are so located.
