The IPD 1979322CSWS is a premium, heavy-duty cylinder liner kit designed for Caterpillar 3400 and C15 series (5.4" bore) engines. Engineered as an upgrade over standard liners, this component features a specialized "Crevice Seal" design introduced by IPD over 25 years ago to address common sealing and vibration issues. Key Features and Design Enhancements:
Wide Crevice Seal: Unlike conventional liners, this model incorporates a wider, rectangular-shaped seal at the bottom, which creates a robust "corking" effect upon installation.
Reduced Cavitation & Movement: The wider seal holds the liner more securely within the engine block, minimizing vibration-induced movement and significantly reducing cavitation erosion.
Same Dimension/Standard Fit: While offering superior performance, the 1979322CSWS retains the exact same top flange and cylinder bore design as the standard 1979322 liner, ensuring proper fitment and compatibility.
