Cylinder Liner Reconditioning & Honing

High-Precision Honing & Surface Restoration to OEM Specifications

KIMI provides precision cleaning, inspection, and reconditioning of 2-stroke marine engine cylinder liners, restoring critical surface geometry and the OEM-specified crosshatch pattern essential for proper lubrication, piston-ring sealing, and long-term durability.

Through controlled honing and precision machining, we correct wear, glazing, scoring, and out-of-roundness, ensuring optimal oil retention and optimal lubrication and wear performance. Dimensional verification and surface roughness control are performed to meet strict OEM tolerances.

Our reconditioning process restores liner functionality and load-bearing capacity, improving engine efficiency and reducing friction. The result is a cost-effective, high-performance alternative to replacement, extending engine life and ensuring reliable operation.

FAQs

Yes. KIMI undertakes a complete 2-stroke cylinder liner overhaul and reconditioning, including cleaning, inspection, dimensional verification, precision honing, surface restoration, and final quality control.

Using advanced metrology, 3D scanning, and precision machining technologies, we restore cylinder liners to OEM specifications, ensuring reliable sealing performance, improved lubrication, and extended operational life.

Honing is a precision finishing process used to restore the internal surface of a cylinder liner by creating the correct OEM-specified crosshatch pattern.

This surface pattern is critical for:

  • Proper lubrication oil retention
  • Effective piston-ring sealing
  • Reduced friction and wear
  • Improved engine efficiency and durability

KIMI performs high-precision honing with surface finish accuracy up to Ra 0.4 µm, ensuring optimal liner performance and long service life.
