Mistake #2 - Not reading the suggested ring end gaps provided by the piston manufacturer. "Many ring suppliers only provide data on OEM ring gaps. Follow the ring gap instructions for the pistons you are using. Never use OEM ring end gap specs, as the material and applications are wildly different.
Ring Installation. The event of engine downsizing has caused many changes i n almost every engine component. Piston rings are no exception. They have been reduced in diameter as cylinder bores have become smaller, with corresponding width and wall reductions. Compression rings 1.5 mm wide (.0575") are becoming more common than rings which are 2.0mm (.0775") or wider.
Note: We recommend using a piston ring compressor kit when rebuilding 2-cycle equipment to ensure professional results.

Piston rings transfer heat to the cylinder wall. Without good cylinder to ring contact the piston will continue to expand in the bore. At some point the piston will stick or seize. The down side to improper break-in are seized pistons. Modern oil's film strength can be so strong that it can keep the rings from ever contacting the cylinder.

Hydraulic Piston Seals. ›. Piston Seals or Piston Rings are used in hydraulic cylinders for fluid sealing. They are internal to the cylinder head and seal against the cylinder bore, preventing fluid from flowing across the cylinder head. This allows pressure build up on one side of the piston, making the cylinder extend or retract.
