Product Details

Product Overview

This precision-engineered 4BA1 Cylinder Liner is a critical replacement component designed for Isuzu diesel engines. With a precise bore diameter of 206mm, this liner is manufactured to meet OEM specifications, ensuring a perfect fit and reliable performance in demanding industrial applications. It is commonly used in a range of heavy equipment including forklifts, excavators, trucks, loaders, bulldozers, and buses.

The part is identified by the OEM cross-reference numbers 9-11261-802-1 and 5-12111-055-1, making it a direct substitute for the original Isuzu components. As a core part of the engine’s combustion chamber, this cylinder liner provides the hard-wearing surface necessary for the piston rings to seal against, maintaining compression and engine efficiency.

FAQ

Q1: How do I confirm if this cylinder liner fits my engine?
A: First, verify your engine model is an Isuzu 4BA1. Then, check your existing liner for the OEM numbers 9-11261-802-1 or 5-12111-055-1. Finally, measure the bore diameter of your old liner; it should be 206mm. If all three match, this part is a direct fit.

Q2: What is the recommended installation procedure for this liner?
A: Installation should be performed by a qualified diesel mechanic. The liner should be installed using a proper press tool to avoid distortion. Ensure the engine block bore is clean and free of debris. After installation, check the liner protrusion above the block deck to ensure it is within the engine manufacturer’s specified range.

Q3: Can this liner be used with standard piston rings?
A: Yes, this OEM-size liner is designed to work with standard-size piston rings for the Isuzu 4BA1 engine. For best results, we recommend replacing the piston rings and pistons at the same time to ensure proper break-in and sealing. Always use high-quality lubricant during assembly.
