FAQ

Q1: Is this cylinder liner a direct replacement for the original Hitachi part?
Yes, this liner is manufactured to match the exact OEM specifications of the 1-87812859-0 and 1-11261380-2 parts. It requires no modifications for installation on the 6WG1 or 6WF1 engine blocks.

Q2: What is the recommended installation procedure for this liner?
We recommend using a professional cylinder liner installer tool to press the liner into the block. Ensure the 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 tolerance (typically 0.02mm to 0.10mm).

Q3: How can I verify the quality of this liner before installation?
We recommend visually inspecting the liner for any scratches or damage. You can also measure the inside diameter of the liner with a bore gauge and compare it to the piston size. Our liners are supplied with a protective coating to prevent rust; this should be cleaned off with a solvent before installation.
