Product Detail

Cummins ISG Engine Cylinder Liner (Part No. 4309570, 3697684, 3696802)

Product Introduction

The cylinder liner is a critical component within the engine block, serving as the inner wall of the cylinder where the piston travels. It provides a wear-resistant surface and ensures proper sealing for combustion. This high-quality replacement cylinder liner is specifically designed for Cummins ISG series engines, ensuring optimal performance and durability. Available under part numbers 4309570, 3697684, and 3696802, this liner is manufactured to meet stringent quality standards.

Applicable Equipment

This cylinder liner is suitable for various equipment powered by the Cummins ISG engine series. Common applications include:

Heavy-Duty Trucks
City Buses and Coaches
Construction Equipment (certain models)
Other industrial applications utilizing the Cummins ISG engine

Application Scenarios & Case Study

Cummins ISG engines are workhorses used in demanding environments. This cylinder liner is essential for maintaining engine integrity in applications such as:

Long-Haul Transportation: Trucks covering vast distances require reliable engines. A worn liner can lead to significant power loss and increased emissions.
Urban Logistics: Delivery trucks and buses with frequent starts and stops put considerable stress on engine components.
Construction Sites: Equipment operating under heavy loads and often in harsh conditions.

Case Study Example: A major logistics fleet replaced worn cylinder liners with high-quality equivalents in their Cummins ISG-powered trucks. This resulted in a measurable 15% reduction in oil consumption, extended engine service intervals, and a significant decrease in unplanned downtime, demonstrating the impact of using reliable internal engine components.

Installation Tips & Troubleshooting

Proper installation is crucial for the performance and longevity of a cylinder liner. Here are common issues and their solutions:

Issue: Improper cleaning of cylinder bore in the block.
Solution: Thoroughly clean and inspect the bore for debris, rust, or damage before installation. Use appropriate cleaning tools and solvents.
Issue: Damage to liner or block during installation.
Solution: Use specialized liner installation tools. Never force the liner into place. Ensure proper alignment.
Issue: Incorrect liner protrusion/standout.
Solution: This is critical for head gasket sealing. Precisely measure protrusion after installation according to the Cummins service manual specifications. Adjust shims if necessary.
Issue: Insufficient lubrication during installation.
Solution: Apply a suitable lubricant (often engine oil or specialized assembly lube) to the liner bore and outer liner surface to facilitate smooth installation and prevent scoring.
Issue: Liner seating issues.
Solution: Ensure the liner is fully seated against its register in the block. Verify with feeler gauges if needed.

Always refer to the official Cummins ISG service manual for detailed installation procedures, torque specifications, and critical measurements.
