NOTE:

Before reinstalling used rings or installing new rings, the ring clearances must be checked.

Wipe the cylinder bore clean.
Insert the ring in the cylinder bore.
NOTE:
The ring gap measurement must be made with the ring positioned at least 12 mm (0.50 inch.) from bottom of cylinder bore.
Using a piston, to ensure that the ring is squared in the cylinder bore, slide the ring downward into the cylinder.
Using a feeler gauge check the ring end gap. Replace any rings not within specification.
