Description
Durable Cylinder Block Sleeve for Mitsubishi S6KT
This 5I7523 / 5I-7523 cylinder block sleeve is used on Mitsubishi S6KT diesel engines, providing a stable and wear-resistant working surface for the pistons and rings. It helps restore proper compression and sealing in worn engines, reduce oil consumption and smoke, and extend the service life of S6KT engines in construction and industrial applications.
High-Strength Material & Accurate Machining
The sleeve is manufactured from high-quality alloy cast iron with controlled hardness and microstructure suitable for heavy-duty diesel operation. Advanced machining and honing processes are applied to achieve a smooth cylinder surface, accurate roundness and correct bore size. This supports good lubrication, fast running-in and long service life under high temperature and high load conditions.
Strict Quality Control
Each cylinder block sleeve is produced under a controlled process and inspected before shipment. Dimensional checks, hardness tests and surface finish inspections are carried out to keep consistency between batches. Sample sleeves are installed and tested on S6KT engines to verify sealing performance, heat transfer and running behavior during operation.
Stable Supply & Flexible Shipping
Regular stock and scheduled production support engine rebuilders, workshops and parts distributors who service Mitsubishi S6KT engines. Each sleeve is packed with anti-rust protection and delivered in strong export cartons or wooden cases to avoid damage in transit. Worldwide shipment is available by TNT, DHL, FedEx, UPS, air freight or sea freight according to your requirements.
