Engine Piston Kit-6754-32-2111

PRODUCT DESCRIPTION:

1. High-efficiency Combustion Chamber Sealing The precisely matched piston and piston rings form a perfect airtight seal for the engine cylinder combustion chamber, effectively preventing the leakage of mixed gas and combustion exhaust gas, ensuring sufficient fuel combustion, maximizing the engine's power output and thermal efficiency.

2. Reliable Load Bearing & Power Transmission The forged high-strength piston bears the huge explosive pressure generated by fuel combustion in the cylinder, and transmits the linear reciprocating motion to the crankshaft through the piston pin and connecting rod stably, realizing the conversion of thermal energy to mechanical energy for the heavy-duty engine.

3. Precise Oil Control & Lubrication Balance The special-structured oil control ring scrapes off the excess lubricating oil on the cylinder wall to keep a thin and uniform oil film, which reduces friction between the piston and cylinder wall while preventing oil from entering the combustion chamber to cause carbon deposition and oil consumption.

4. Excellent Heat Dissipation & High-temperature Resistance The high-performance aluminum alloy piston has excellent thermal conductivity, quickly conducts the high heat generated by combustion to the cooling system and cylinder wall, and maintains stable structural performance at high temperature to avoid piston deformation and ablation.

5. Low-friction Operation & Wear Resistance The anti-wear coating on piston rings and the lubricated piston pin bushing minimize the friction coefficient between moving parts, reduce mechanical wear of the piston, cylinder liner and piston rings during high-speed and high-load operation, and ensure the long-term smooth operation of the engine.

PRODUCT DETAILS

Product Advantages

1. OEM Standard Complete Matching & Precision Fit Produced in strict accordance with Komatsu SAA6D107E engine's original factory drawings and tolerance standards, all components of the kit are pre-matched and calibrated for precision, with perfect dimensional compatibility between piston, piston rings and piston pin. Direct replacement without secondary adjustment, ensuring the best assembly effect.

2. High-quality Forged Material & Durable Structure The piston is made of one-piece forged high-strength aluminum alloy with high fatigue resistance and impact resistance, which can withstand the ultra-high combustion pressure of heavy-duty engines; all metal parts are treated with surface hardening and anti-corrosion, effectively improving the overall service life of the kit.

3. Professional Coating & Process Optimization Piston rings are coated with wear-resistant and anti-seizure ceramic coating, and piston pin is processed by high-precision grinding with super smooth surface; the oil control ring adopts a three-piece combined structure for better oil scraping effect, solving the problems of cylinder wall wear and excessive oil consumption of heavy-duty engines.

4. Strong Adaptability to Harsh Working Conditions The whole kit has passed professional performance tests such as high-temperature combustion, high-pressure load, continuous fatigue and dust resistance. It can work stably in the harsh working environment of heavy-duty engineering machinery such as high load, long continuous operation and frequent start-stop, fully adapting to the operation requirements of SAA6D107E engine.

5. One-stop Replacement & High Cost PerformanceIntegrated complete kit design, including all core components of the piston assembly, avoiding the trouble of separate purchasing and matching of single parts; the product performance is close to Komatsu original genuine parts, with a more favorable procurement price, reducing the maintenance time and overall operation and maintenance cost of engineering machinery.


Installation & Maintenance Tips

1. Clean all components of the kit and the engine cylinder liner, connecting rod small head before installation, remove oil stains, rust, burrs and impurities; ensure the mating surface is smooth and flat without obvious scratches.

2. Install the piston rings in strict accordance with the marking and installation sequence (compression ring first, then oil control ring), pay attention to the installation direction of the rings (the marked side faces the piston top), and ensure the ring gaps are evenly staggered to avoid gas leakage.

3. Heat the piston evenly to 60-80℃ with hot oil or a special heater before installing the piston pin (avoid open fire heating), and install the piston pin and circlips in place to prevent the pin from loosening during operation.

4. Apply a thin and uniform layer of engine oil on the piston, piston rings and cylinder liner inner wall before assembling the piston into the cylinder, use a piston ring compressor to press the piston rings, and push the piston into the cylinder smoothly to avoid scratching the cylinder liner and piston rings.

5. After installation, check the clearance between the piston and cylinder liner, and the flexibility of the piston pin; start the engine at idle speed for running-in (1-2 hours), and avoid high-speed and high-load operation during the running-in period. Regularly check the engine oil consumption and exhaust status, and replace the engine oil and filter element in time after running-in.
