Cylinder Kits for Caterpillar 3412C Engines

Cylinder Kit – 14.3:1 Compression Ratio

This piston and liner kit is engineered for Caterpillar 3400 series engines and is fully compatible with the Caterpillar 3412C. The 14.3:1 compression ratio provides the balance between durability and efficient combustion, making it an ideal choice for high-load applications such as marine propulsion, heavy industrial machinery, and power generation units.

This kit is designed for a wide range of arrangement numbers across the Caterpillar 3400 platform. Engines with serial prefixes 99U, 1LG, 1TS, TAM, 5RL, 60M, 7HG, 9BR, RLR, and RTY are fully supported.

The cylinder kit includes:

• Precision-engineered piston with crown designed for optimal fuel burn.

• Cylinder liner manufactured from wear-resistant materials for extended engine life.

• Piston rings that ensure maximum compression retention and reduced oil consumption.

• Retainers and seal components required for installation.

Cylinder Kit – 14.1:1 Compression Ratio

This kit is configured for Caterpillar 3400-series engines including the 3412C, featuring a slightly lower 14.1:1 compression ratio. This design offers smoother operation and reduced combustion stress while maintaining Caterpillar-level performance standards.

Best suited for mixed-duty cycles and applications where long engine life and fuel efficiency are prioritized, the kit includes pistons, liners, rings, retainers, and liner seals. Engines with prefixes such as 3JK, 60M, 7BL, RTY, and 8RGfall into the compatibility range for this build.

Cylinder Kit – 13.0:1 Compression Ratio

Specifically tailored for the Caterpillar 3412C, this kit offers a 13.0:1 compression ratio that reduces thermal load on the engine while maintaining reliable power output. Lower compression designs are often used in continuous-duty engines operating in hot climates or under heavy industrial demands where heat management is critical.

Arrangement numbers supported include 1483588, 1483596, and 1484439, all tied to the 3412C’s production range. The kit contains the piston, liner, rings, and all necessary seals for a complete rebuild on a per-cylinder basis.

Piston Ring Sets for Caterpillar 3412C Engines

Piston Ring Set – For 3412C Low-Compression Applications

Designed for arrangement numbers including 1483588, 1483596, and 1484439, this ring set restores compression integrity and ensures efficient combustion cycles. These rings are built with wear-resistant coatings to minimize friction, reduce blow-by, and extend overhaul intervals.

Piston Ring Set – For 14.1:1 Ratio Engines

This set is designed to match pistons in the 14.1:1 compression ratio kits and works with arrangement numbers covering Caterpillar 3412C builds across construction and marine platforms. Built for resilience in heavy-duty environments, these rings maintain sealing capability even under prolonged high-temperature operation.

Piston Ring Set – Multi-Engine Compatibility (3406, 3408, 3412)

This universal piston ring set supports Caterpillar 3406, 3408, and 3412 engines including the 3412C. It ensures operators can standardize maintenance across multiple engine models within the same fleet. These rings are particularly valuable for mixed-equipment operators in shipping or mining sectors where multiple Caterpillar platforms are used.

Cylinder Liners and Related Components

Cylinder Liner Seal Kit

Every liner installation requires a reliable seal between liner and block. This kit, designed for Caterpillar 3406, 3408, and 3412 engines, includes the seals necessary to prevent coolant and oil leaks while maintaining combustion chamber integrity. One kit is required per liner.

Cylinder Liner – Heavy-Duty Construction

This component serves as the wear surface for the piston assembly. Built with precision and hardened for durability, the liner supports efficient combustion cycles and protects the block structure. Caterpillar 3412C operators rely on these liners for long service life, even under heavy continuous-duty operations such as in offshore drilling or standby generators.

Piston Pin Retainer

These retainers secure the piston pin within the assembly, ensuring smooth piston movement under extreme loads. For Caterpillar 3406, 3408, and 3412 engines—including the 3412C—two retainers are required per piston.
