🔹Product Overview

Cylinder Liner Part No.5530375 is an important wear‑resistant inner sleeve component for ISL9.5 and QSL9.3 diesel engines. It forms the combustion working chamber together with piston and piston rings, bears high‑temperature gas impact and reciprocating friction movement of piston assembly. This replacement cylinder liner resolves typical failures including cylinder bore scratch, excessive oil consumption, blow‑by gas and engine power reduction caused by original liner inner‑wall wear, scoring and deformation. Every cylinder liner passes strict inner‑diameter dimensional inspection, surface hardness test and appearance defect checking before shipment.
