Product Features

• Structure: Made of high-strength boron cast iron, with a honed inner surface for precision and a nitride coating for enhanced wear resistance. It features a flange design for secure installation in the cylinder block.

• Performance: The boron cast iron material provides excellent heat dissipation and rigidity, while the nitride coating resists wear from piston movement and high-pressure combustion. The honed surface ensures optimal piston ring sealing and oil retention.

• Design: A replaceable dry liner design, allowing for cost-effective engine overhauls without replacing the entire cylinder block.

Core Function

• Forms the inner wall of the combustion chamber, guiding the piston’s reciprocating motion and withstanding the pressure and temperature of combustion.

• Maintains precise cylinder geometry to ensure efficient combustion, reduce oil consumption, and minimize emissions.

• Protects the cylinder block from direct wear, extending the service life of the engine’s main structure.

Key Features and Benefits of Cylinder Liner VG1500010344

Engineered for Demanding Conditions

The VG1500010344 cylinder liner is manufactured from high-strength centrifugal cast iron alloy, delivering superior thermal conductivity and exceptional resistance to cavitation erosion. Every liner undergoes precision honing to achieve the optimal crosshatch pattern that promotes proper oil retention and minimizes piston ring wear.

• Extended Service Life: High-phosphorus cast iron composition resists corrosive wear from combustion byproducts, extending overhaul intervals significantly.
• Precise Dimensional Accuracy: Machined to tolerances within ±0.01mm, ensuring perfect piston-to-liner clearance and optimal compression sealing.
• Superior Thermal Management: Uniform wall thickness promotes even heat dissipation, preventing hot spots that cause premature liner distortion.
• Cavitation Resistance: Outer surface treatment protects against coolant-side pitting, a common failure mode in wet-type cylinder liners.
• Drop-In Replacement: 100% interchangeable with the original SINOTRUK part, requiring no modifications during installation.

Cost Advantages for Procurement Managers

By sourcing the Cylinder Liner VG1500010344 directly from our China-based supply chain, you eliminate multiple intermediary markups. Our factory-direct model typically delivers 30–50% cost savings compared to aftermarket distributors in destination markets, without compromising on dimensional accuracy or material grade.

Frequently Asked Questions – Cylinder Liner VG1500010344

What is the expected service life of this cylinder liner?

Under normal operating conditions with proper cooling system maintenance, the VG1500010344 cylinder liner typically delivers 300,000 to 500,000 km before requiring replacement. Actual lifespan depends on load conditions, maintenance practices, and coolant quality.

Is VG1500010344 a wet-type or dry-type cylinder liner?

This is a wet-type cylinder liner, meaning it makes direct contact with engine coolant on its outer surface. This design provides superior heat dissipation but requires proper O-ring sealing to prevent coolant leakage into the crankcase.

What sealing rings are needed when installing this cylinder liner?

Installation requires upper copper sealing gasket and lower rubber O-rings (typically 2–3 per liner) to prevent coolant intrusion. We recommend replacing all sealing components during every liner change to ensure a leak-free assembly.

Can this liner be used in Euro III emission standard engines?

Yes. The VG1500010344 is compatible with both Euro II and Euro III variants of the WD615 engine series. The bore dimensions and port geometry remain identical across these emission tiers.

What is the minimum order quantity for wholesale pricing?

We offer competitive pricing starting from as few as 6 pieces per order. Larger volume commitments (50+ pieces) unlock additional tier pricing. Contact our team for a customized quotation based on your annual consumption forecast.

How should I store cylinder liners before installation?

Store in a dry, temperature-controlled environment with the protective anti-rust oil coating intact. Keep liners in their original packaging in a horizontal position to prevent bore distortion. Shelf life with protective coating is approximately 12 months under proper storage conditions.
