Piston rings / Ø 83 mm / 2 x 2 x 4 mm / Kubota D1503/V2003 / 16419-21050 / 16467-21051

Engine piston rings (piston 1G770-2110 ) with a diameter of 83 mm and a thickness of 2.00 x 2.00 x 4.00 mm for Kubota tractors of the Kubota series with Kubota D1503 , Kubota V2003 and other engines.

Piston rings seal the space between the piston walls and the cylinder walls. During combustion of the fuel mixture in the engine compartment, chemical energy is exchanged for mechanical energy, which is why we care about the tightness of these two elements. The second important role that piston rings play in an engine is to scrape excess oil from the cylinder walls during piston movement, thus ensuring adequate lubrication. There are three basic types of rings in combustion engines:

• sealing rings,
• scraper rings,
• compression and scraper rings.

When replacing the rings, pay special attention to the order in which they are placed on the piston. We install the rings in the appropriate order, install the scraper ring first, the sealing ring second and the oil ring third.

The first signs of piston ring wear:

• higher fuel consumption,
• engine oil loss,
• power loss,
• black smoke from the exhaust pipe of a hot engine,
• uneven engine operation at idle speed,
• unnatural, easily audible sound from the engine area,
• power loss,
• problems with starting the engine,

All symptoms should be consulted with a professional service in order to properly diagnose and check the engine for the need to replace the rings or overhaul the engine.
