• Install the 2nd ring and 1st ring.
NOTE:
1st ring and 2nd ring differ in shape.
• The 1st and 2nd piston rings should be installed with their
marks facing up.

NOTE:
Before inserting the piston into the cylinder, check that the gaps
are properly positioned.
When installing the spacer, be careful not to allow its
two ends to overlap in the piston ring groove.
