Product Overview

This premium Kubota Cylinder Liner (Part Number: 1J751-02310) is a direct replacement component specifically engineered for the Kubota V3307 and V3307-T diesel engines. As a critical wear part within the engine block, this liner ensures optimal piston sealing, heat dissipation, and long-term durability. Our inventory supports global B2B supply chains, shipping reliably to major industrial markets across North America, Europe, Asia-Pacific, and the Middle East.

Key Features & Benefits

• Precision Engineering: Manufactured to OEM specifications for a perfect press-fit installation, eliminating the risk of slippage or bore distortion.
• Superior Wear Resistance: Constructed from high-grade cast iron with a hardened inner bore surface to withstand extreme combustion pressures and temperatures.
• Enhanced Heat Transfer: Optimized wall thickness and surface finish promote efficient heat dissipation from the piston to the engine coolant, reducing hot spots.
• Corrosion Protection: The outer surface features an anti-corrosion coating to resist cavitation and pitting from coolant interaction.
• Extended Service Life: Designed for high-hour applications in construction, agricultural, and industrial machinery, offering a lifespan comparable to the original Kubota part.

FAQ

Q1: Is the 1J751-02310 cylinder liner a direct fit for my Kubota V3307 engine, or does it require machining?
A: This liner is a standard size, direct replacement part designed for a press-fit installation. It does not require additional boring or honing if the engine block is in good condition. However, we recommend measuring the block bore to ensure it is within the specified tolerance for a proper interference fit (typically 0.02-0.05mm). If the block has been previously machined, an oversized liner may be required.

Q2: What is the recommended installation procedure for this dry cylinder liner?
A: For a dry liner like this, the block bore must be clean, dry, and free of burrs. Apply a thin layer of clean engine oil to the outer surface of the liner. Using a hydraulic press or a specialized liner installation tool, press the liner in evenly until it is flush with the top of the block. Never use a hammer directly on the liner, as this can distort it. After installation, check for liner protrusion (typically 0.02-0.10mm above the block deck) to ensure proper head gasket sealing.

Q3: How can I tell if my V3307 engine needs new cylinder liners?
A: Common symptoms include excessive oil consumption (blue smoke from exhaust), loss of compression (hard starting, rough idle), audible knocking from the lower engine area, and visible coolant contamination in the oil (indicating a cracked liner). A compression test or a leak-down test will confirm if the cylinder seal is compromised. Visually, scoring or vertical grooves on the liner’s inner surface are a clear sign it needs replacement.
