FAQ

Q1: Is this cylinder liner a genuine Cummins part or an aftermarket replacement?

This product is a high-quality aftermarket replacement manufactured by. It is designed to meet or exceed OEM specifications for the Cummins 4BT engine (OEM size). It is not an original Cummins part but offers a cost-effective alternative for engine rebuilds.

Q2: How do I confirm that this liner will fit my engine?

Please verify your engine model (must be Cummins 4BT) and confirm the liner size. This part is for standard OEM size. If your engine has been previously bored or requires an oversized liner, this part may not fit. We recommend checking your old liner’s inner diameter (ID) and outer diameter (OD) against the specifications provided in the technical table.

Q3: What is the recommended installation procedure for this cylinder liner?

Installation should be performed by a qualified diesel mechanic. The liner typically requires a light press fit into the engine block. Ensure the block bore is clean and free of debris. Apply a thin layer of engine oil or assembly lubricant to the outer surface of the liner before pressing. After installation, check the liner protrusion to ensure it is within the engine manufacturer’s specifications to prevent head gasket failure.
