>>B<< Oil Ring Installation

Install the oil ring spacer first into the piston ring groove, followed by the upper side rail and then the lower side rail.
CAUTION: Do not use a ring expander on side rails as they may break when the gap is opened.
Side rails can be installed easily by first inserting one end of the rail into the piston groove, then pressing the rail into place with finger.
With the side rails installed onto the piston, check that they can be rotated smoothly in both directions.
