Product Details
Product Overview
This premium piston and ring set is specifically engineered for the Komatsu PC130-11 excavator, featuring the robust SAA4D95LE-7 diesel engine. As a critical component for engine rebuilds and overhauls, this kit includes the genuine-spec piston (Part No. 6276-31-2110) and the matching piston ring set (Part No. 6276-31-2300). Designed to restore compression, reduce oil consumption, and maximize engine power output, this assembly is a direct replacement for the original Komatsu components. We supply heavy-duty engine parts globally to markets in North America, Europe, Southeast Asia, the Middle East, and Australia, ensuring fast and reliable shipping from our strategic distribution hubs.
Key Features & Benefits
Precision Engineering: Manufactured to strict OEM tolerances for a perfect fit in the SAA4D95LE-7 engine block, ensuring optimal cylinder sealing and compression.
Superior Durability: Constructed from high-strength aluminum alloy (piston) and ductile iron (rings) to withstand extreme combustion pressures and temperatures.
Enhanced Oil Control: The ring set features advanced oil ring technology to minimize oil consumption and blow-by, extending engine service life.
Reduced Friction: Precision-ground ring surfaces and optimized piston skirt profiles reduce internal friction, improving fuel efficiency and horsepower.
100% Tested: Every unit undergoes rigorous dimensional and material composition checks to guarantee reliability in demanding excavator applications.

FAQ
Q1: Is this piston set compatible with the Komatsu PC130-8 or PC130-7 models? A: No. This specific piston (6276-31-2110) and ring set (6276-31-2300) are designed exclusively for the SAA4D95LE-7 engine found in the PC130-11 model. Earlier models (PC130-7, PC130-8) use different engine variants (e.g., S4D95LE-1) and have different part numbers. Please verify your engine model before ordering.
Q2: Does the kit include all rings for one cylinder (compression and oil rings)? A: Yes. The ring set (6276-31-2300) includes all necessary rings for a single piston: typically two compression rings and one oil control ring assembly. You will need to purchase the required number of sets based on your engine’s cylinder count (4 sets for a 4-cylinder engine).
Q3: What is the recommended installation procedure for these pistons? A: We strongly recommend professional installation by a certified diesel mechanic. Key steps include: cleaning the cylinder bore, checking ring end gap, lubricating the piston and rings with clean engine oil, and using a proper ring compressor for installation. Torque the connecting rod bolts to the manufacturer’s specifications (usually 90-110 Nm for this engine, but please consult your service manual).
