PRODUCTS DESCRIPTION

Engine parts list

Product Description

This cylinder liner assembly is tailored for D12 and D13 series diesel engines of excavation machinery, serving as core complete parts for engine overhaul and routine maintenance. The full set includes precision-machined cylinder liners, piston ring sets, sealing O-rings, gaskets, oil seals and matching auxiliary sealing components, which can be directly used without extra scattered purchases. Manufactured in strict accordance with original factory assembly tolerance standards, it fits heavy-duty working conditions of engineering excavators. All components are packed with individual sealed packages, meeting engine repair and replacement demands of excavation equipment used in mining, infrastructure construction, earthmoving and other scenarios.

Product Advantages

Strong Compatibility: Customized and processed according to structural parameters of D12 and D13 models, it features highly matched dimensional tolerance and excellent fitting performance after installation, eliminating secondary grinding modification and greatly cutting maintenance time.
Integrated Complete Kit: It provides all sealing and kinematic parts needed for overhaul in one-stop supply, avoiding model mismatch and rework caused by missing parts from scattered procurement, and improving maintenance efficiency significantly.
Premium Protective Packaging: Each individual component adopts moisture-proof and shock-proof sealed package, while large parts use thickened protective plastic wrapping to prevent collision damage and damp aging during long-distance storage and transportation.
Wide Working Condition Adaptability: It can adapt to outdoor engineering environments with high/low temperature, heavy dust and strong vibration, and satisfy the long-time continuous heavy-load operation requirements of excavation equipment.
Strict Quality Control: It follows industrial-grade component inspection standards throughout production with stable batch quality, which effectively reduces the frequency of subsequent engine rework and repairs.

Product Performance

Superior Wear Resistance: The cylinder liner base is made of high-strength wear-resistant alloy with inner wall processed by precision honing technology to lower friction coefficient. It resists long-term abrasion from piston reciprocating movement and greatly extends the engine overhaul interval.
Reliable Sealing Performance: Matching sealing rings and gaskets are made of special oil and high-temperature resistant elastomer, which can maintain stable elasticity under high-temperature and high-pressure combustion chamber conditions, prevent oil and gas leakage, and keep stable cylinder compression ratio.
Excellent Thermal Deformation Control: The material has optimized thermal expansion coefficient with tiny deformation under temperature fluctuation conditions such as cold start and sudden full-load boost. It keeps reasonable fitting clearance between cylinder wall and moving parts to avoid cylinder scoring and gas blow-by failures.
Stable Power Output: After assembly, qualified cylinder tightness improves combustion efficiency, ensures smooth power output of excavation equipment during operation, optimizes fuel consumption and cuts long-term operating costs.
Strong Medium Aging Resistance: Oil seals and sealing components can resist long-term erosion from diesel and engine lubricating oil with outstanding anti-aging performance. Its sealing service life can match the whole machine service life under year-round non-stop operation of engineering equipment.
