( Brand: Namura Technologies ), ( Manufacturer Part Number: NW-40001-2R ), ( Part Type: Ring Piston )
The Namura NW-40001-2R piston ring is a high-performance replacement option for Yamaha WaveRunner models from 1996 to 2004 with a displacement of 1200cc and a piston diameter of 84mm, specifically for the number 020 engine. This ring is suitable for use with a piston bore measurement of 5mm.
Designed using the latest technology and high-quality materials, this piston ring ensures optimal engine performance and durability. The ring features a precise Tol rangement and a fine pitch, which allows for a snug fit within the engine cylinder. This ensures optimal compression, minimal leakage, and reduced friction.
The outer diameter of the ring measures 40mm, and it is made of a high-temperature alloy steel material, which is resistant to wear and tear, ensuring a long service life. The inner diameter is 31.5mm, and the minimum width is a precise 5mm, allowing for an accurate seal between the piston and cylinder wall.
One notable feature of this piston ring is its anti-detonation design. The ring is engineered to prevent detonation, a condition where the fuel-air mixture in the cylinder detonates prematurely instead of burning smoothly. This results in a smoother running engine and improved overall performance.
Moreover, this piston ring is also designed to provide improved sealing, reducing oil consumption and minimizing the risk of engine damage caused by oil leakage. It also helps to prevent water intrusion, marginally reducing engine cooling and improving efficiency.
In conclusion, the Namura NW-40001-2R piston ring is a high-performance, reliable, and efficient replacement option for Yamaha WaveRunner engines from 1996 to 2004, with a displacement of 1200cc and a piston diameter of 84mm, and a bore measurement of 5mm. Its precise measurements, anti-detonation design, and high-quality materials ensure optimal engine performance and durability.
The Namura NW-40001-2R piston ring is engineered for use in Yamaha 1200 Personal Watercrafts (PWCs) from 1996 to 2004.
