Unleashing Performance: The PISTON 95MM OEM ME200689 STD ALFIN+OG for MITSUBISHI 4M40
At Quanzhou Helong Machinery Parts Co., Ltd., we understand that the heart of any robust machine lies in the quality of its components. For owners and operators of machinery powered by the venerable MITSUBISHI 4M40 engine, maintaining peak performance is paramount. This is where the PISTON 95MM OEM ME200689 STD ALFIN+OG plays a crucial role, ensuring durability, efficiency, and the longevity of your engine.

Why the MITSUBISHI 4M40 Engine Deserves the Best
The MITSUBISHI 4M40, an inline 4-cylinder SOHC diesel engine, is renowned for its reliability and widespread use in various applications, from construction equipment to commercial vehicles. With a bore of 95mm and displacements typically ranging from 2.8 to 3.2 liters, its design demands precision-engineered parts to deliver its specified power and torque outputs. Inferior components can lead to reduced efficiency, increased fuel consumption, and ultimately, costly downtime.
Our commitment to providing top-tier engine parts stems from our extensive experience and deep understanding of machinery. We recognize that every component contributes to the overall health of your engine, and pistons, in particular, are at the forefront of the combustion process, enduring immense heat and pressure.
Introducing Our Premium PISTON 95MM OEM ME200689 STD ALFIN+OG
Our PISTON 95MM OEM ME200689 STD ALFIN+OG is specifically designed to meet or exceed the original equipment manufacturer (OEM) standards for the MITSUBISHI 4M40 engine. This piston features an ALFIN insert and Oil Gallery (OG), critical enhancements that significantly improve its performance and lifespan.
ALFIN Insert: This metallic insert is strategically cast into the piston crown, reinforcing the ring groove area. It dramatically enhances wear resistance, especially in high-temperature, high-pressure environments common in diesel engines. This prevents ring groove wear, which is a common failure point in pistons, ensuring optimal compression and reduced oil consumption over time.
Oil Gallery (OG): The integrated oil gallery helps to cool the piston crown from within by circulating engine oil. This internal cooling mechanism prevents localized overheating, reduces thermal stress, and helps maintain the structural integrity of the piston under extreme operating conditions. The result is a more stable and reliable combustion process.
