Product Details
Product Overview
This is a high-quality replacement engine piston designed for Kubota V3300 and V3300T diesel engine platforms. Identified by the OEM part number 1C050-21112, this piston is specifically configured for the 16-valve (16V) cylinder head configuration found in later V3300T models. It serves as a critical component for maintaining compression and combustion efficiency in industrial and construction machinery.
Manufactured to OEM size specifications, this piston is commonly used in a variety of heavy equipment including excavators, forklifts, bulldozers, loaders, buses, and trucks. As a direct replacement part, it is designed to restore engine performance and reliability when rebuilding or repairing Kubota diesel engines in the V3300 series.
Key Features & Benefits
OEM Specification Fit: Manufactured to the exact dimensions of the original Kubota piston (1C050-21112), ensuring proper clearance and ring alignment for V3300T-16V engines.
Durable Construction: Built from high-strength alloy materials capable of withstanding the high compression and thermal loads typical of turbocharged diesel engines.
Precision Engineering: Features precise pin bore placement and ring groove machining to minimize friction and oil consumption during operation.
Cost-Effective Replacement: Offers significant savings compared to genuine Kubota parts while maintaining reliable performance for rebuild applications.
Versatile Application: Suitable for multiple equipment types including excavators, loaders, and forklifts powered by V3300 or V3300T engines.
Factory Tested: Each piston undergoes outgoing quality inspection with video documentation available upon request to verify specifications.

FAQ
Q1: How do I confirm this piston fits my Kubota V3300T engine? Check your engine’s valve cover. The V3300T-16V uses a 16-bolt valve cover pattern with two rows of rocker arms visible. If your engine has 8 bolts on the valve cover, it is likely an 8V configuration and will require a different piston (typically part number 1C050-21110). Always verify your engine serial number against Kubota parts diagrams for definitive compatibility.
Q2: Can I install this piston without replacing the piston rings? It is strongly recommended to always install new piston rings with any replacement piston. Reusing old rings can lead to improper seating, increased oil consumption, and reduced compression. For optimal results, order a complete piston ring set (typically part numbers 1C050-21130 or equivalent) to match this piston’s ring groove specifications.
Q3: What is the recommended break-in procedure after installing new pistons? After installation, run the engine at idle (800-1000 RPM) for 15-20 minutes without load to allow the piston rings to seat properly. Avoid sustained high RPM or heavy loading for the first 50 operating hours. Change the engine oil and filter after the initial 50-hour break-in period to remove any wear particles from the ring seating process. Use API CJ-4 or CK-4 grade diesel engine oil with proper viscosity for your operating climate.
