Piston rings / Ø 88 mm / 2.00 x 2.00 x 4.00 mm / Yanmar 3TNV84/4TNV84/3TNV88/4TNV88 / Yanmar EF352T/EF453T / 129004-22500

Piston rings (piston 129005-22080 ) with a diameter of 88 mm and a thickness of 2.00 / 2.00 / 4.00 mm for Yanmar tractors of the Yanmar EF352T, Yanmar EF453T series with Yanmar 3TNV84, Yanmar 4TNV84, Yanmar 3TNV88, Yanmar 4TNV88 and other engines.

Piston rings seal the space between the piston walls and the cylinder walls. During the combustion of the fuel mixture in the engine chamber, chemical energy is exchanged for mechanical energy, which is why we care about the tightness of these two elements. The second important role played by piston rings in the engine is to scrape excess oil from the cylinder walls during the piston's movement, thus ensuring proper lubrication. In combustion engines, we distinguish three basic types of rings:

• sealing rings,
• scraper rings,
• compression-scraper rings.

When replacing the rings, special attention should be paid to the order in which they are placed on the piston. The rings are installed in the correct order, the scraper ring is installed first, the sealing ring second and the oil ring is installed third.
