Caterpillar cylinder liner 473-9034 is a critical component in Caterpillar engine cylinder blocks, serving as a replaceable wear surface for the piston. It forms a tight seal with the cylinder head and piston rings, maintaining proper compression and preventing combustion gas leakage—essential for engine power output, fuel efficiency, and durability in heavy-duty applications like mining, construction, and industrial machinery. Ningbo Qiuning Trading Co., Ltd., a professional supplier, offers both genuine and aftermarket versions to meet diverse operational needs.
In terms of performance, the cylinder liner is crafted from high-strength cast iron or alloy steel with specialized heat treatment, achieving exceptional wear resistance and thermal conductivity. Its inner surface is precision-honed to a smooth finish (Ra ≤0.8μm), reducing friction with the piston and minimizing oil consumption. The liner can withstand extreme combustion pressures (over 200 bar) and temperatures (up to 450°C), maintaining dimensional stability to prevent warping or cracking. It features proper wall thickness and cooling passages (where applicable) to ensure efficient heat dissipation, protecting the engine block from overheating.
For compatibility, 473-9034 is specifically engineered for certain Caterpillar engine models, matching original dimensions (bore diameter, length, and wall thickness) and tolerance standards. This ensures seamless installation into the cylinder block, with precise fits that guarantee compression integrity and proper piston clearance. It integrates perfectly with Caterpillar pistons, rings, and gaskets, maintaining the engine's original performance specifications.
Ningbo Qiuning Trading Co., Ltd. provides genuine cylinder liners that adhere to Caterpillar’s strict quality standards, undergoing rigorous testing for dimensional accuracy, material strength, and wear resistance—ideal for critical applications where reliability is paramount. Aftermarket liners, produced by reputable manufacturers with advanced casting and machining technology, replicate the genuine part’s performance and fit at a competitive price, offering a cost-effective solution for engine overhauls or repairs.
Our professional team assists with model verification to ensure the liner fits your Caterpillar engine. Whether for routine maintenance or major rebuilds, we deliver quality components. For inquiries or orders, contact:
