Note:
- Do not confuse the top and second rings: the top ring is chrome-coated and the second ring is not coated (black).
- Be careful not to damage the piston and rings during assembly.
- To install the oil ring, install the spacer first, then install the side rails.
- Stagger the ring end gaps 120° as shown.
After installing the rings, check that they rotate freely without sticking.
