FAQ

Q1: How do I confirm this 235.5mm liner fits my specific Cummins engine?
A: First, check the engine data plate for the exact model (e.g., 6CT8.3). Second, measure the bore diameter of your old liner or the cylinder block. This liner is specifically for a 235.5mm bore. Finally, cross-reference your existing part number (e.g., 3948095) with the list provided above. If you are unsure, contact our support team with your engine serial number.

Q2: What is the recommended installation procedure for this dry cylinder liner?
A: Dry liners require precise installation. The cylinder bore must be clean and free of debris. Apply a light coat of clean engine oil to the liner’s outer surface. Using a specialized liner press tool, press the liner in slowly and evenly until it is seated correctly. Do not use a hammer. After installation, check the liner protrusion above the block deck to ensure it is within the engine manufacturer’s specifications (typically 0.03mm to 0.10mm).

Q3: Can I reuse old piston rings with a new cylinder liner?
A: No. When installing a new cylinder liner, you must always install new piston rings. The new liner has a specific surface finish (plateau honing) designed to be worn in by new rings. Reusing old rings will lead to poor oil control, blow-by, and premature liner wear. We recommend replacing the piston and rings as a set for optimal performance and engine life.
