FAQ

Q1: Is this cylinder liner a direct fit for my Cummins ISLE340 engine?
A: Yes, this liner is manufactured to the OEM dimensions for the Cummins ISLE340 30 model. However, due to potential engineering updates, we recommend comparing the liner’s outer diameter and flange height with your original part. If your engine serial number falls outside the standard range, please contact us for verification.

Q2: What is the recommended installation procedure for this liner?
A: Installation should be performed by a qualified diesel mechanic. The cylinder bore must be clean and free of debris. We recommend using a proper liner press tool to avoid distortion. After installation, measure the liner protrusion above the block deck to ensure it is within Cummins specifications (typically 0.002-0.005 inches). Always use new O-rings and a suitable lubricant during assembly.

Q3: How can I verify the quality of this product before shipment?
A: We offer a Video Outgoing Inspection service. Before your order ships, we can provide a video showing the physical condition and basic dimensions of the liner. Additionally, a Machinery Test Report can be provided for critical dimensions upon request. This transparency ensures you receive a part that meets your technical requirements.
