**Product Name:** Cylinder Liner
**Apply For:** Cummins Engine
**Engine Model:** NT855
**OEM No.:** 3055099
**Key Features:**
- High-quality cylinder liners produced on 1–8 advanced production lines with strong casting capabilities.
- Available in both wet and dry types, as well as slip fit (F) and press fit (SF) designs.
- Suitable for a wide range of diameters from 55 to 250 mm.
- Surface treatments include oxidation, phosphating, chromium plating, and laser hardening.
- Certified by DIN/ISO 4383 and ISO/TS 16949.
**Installation Guidelines:**
**Wet Cylinder Liners:**
- Ensure the cylinder bore is clean and undamaged before installation.
- Use flange or oversize liners if corrosion is present.
- Check the liner’s projecting length to meet engine manufacturer specifications.
- Apply lubricant before installation and test the cooling system for leaks after fitting.
**Semi-Finished Cylinder Liners:**
- The supporting surface must be vertical and evenly beveled.
- After installation, the inside diameter should be finely bored and honed to the required dimensions.
- Ensure the liner surface is flush with the cylinder block sealing surface; use surface grinding if necessary.
**Finished Cylinder Liners:**
- Clean and inspect the location bore for accuracy and distortion.
- If the bore is out of alignment or damaged, rework it for oversized liners.
- Maintain cylindrical shape of the bore to ensure proper fit of thin-walled liners.
**Air-Cooled Cylinder Liners:**
- Cast iron or light alloy cylinders are used based on engine manufacturer instructions.
- Light alloy cylinders are grouped according to standard installation clearances.
