PRODUCT DESCRIPTION

High-Hardness Alloy Steel & Precision Heat Treatment

This cylinder liner OE MK100-1002106A is manufactured to exact Yuchai engine specifications, using premium alloy steel that undergoes precision casting and heat treatment for maximum structural strength and wear resistance. The product features a precision-ground inner surface that ensures perfect alignment with the piston and minimal friction, while the reinforced outer wall provides excellent heat dissipation and resistance to thermal fatigue. Its machined mounting flanges ensure a secure fit with the engine block, preventing gas leakage and coolant intrusion. The 1:1 original dimensional design ensures seamless installation without modification, delivering reliable, long-lasting engine performance.

Engine Compression Loss & Premature Wear

Truck operators often face critical issues with substandard cylinder liners, including soft material causing rapid wear and reduced compression; poor heat resistance leading to cracking and deformation; and misaligned dimensions causing piston scuffing and engine failure. A faulty cylinder liner leads to power loss, increased fuel consumption and costly engine overhauls. By choosing the genuine OE MK100-1002106A liner, users can instantly resolve these problems, ensuring consistent engine compression and protecting critical moving parts.

OEM Quality & Rigorous Wear Testing

As a key engine block component, this cylinder liner complies with Yuchai and Dongfeng’s strict quality standards and has passed comprehensive third-party tests for wear resistance, pressure integrity and thermal stability. Test data shows the liner maintains dimensional integrity under continuous high-load operation, resists scuffing and scoring under high heat, and meets all applicable engine performance specifications. Each unit undergoes 100% dimensional inspection, hardness testing and surface finish verification before leaving the factory, guaranteeing complete consistency with original factory parts in performance, durability and fit. Backed by official Yuchai traceability codes, this product ensures 100% authenticity and reliable operation.
