The Caterpillar 3406C is one of the most respected engines in the Caterpillar 3400 series, valued for its durability, power output, and versatility in marine and industrial applications. When this engine reaches the point where major service is required, a complete overhaul kit is the best solution to restore it to factory-level performance.

At Diesel Pro Power, we offer complete overhaul kits for the Caterpillar 3406C that provide every essential internal component needed for a full rebuild. Designed to meet OEM specifications, these kits ensure your 3406C engine is rebuilt to deliver reliable power and long service life.

Why Choose a Caterpillar 3406C Overhaul Kit?

Choosing a complete kit over sourcing individual components offers multiple advantages:

• All-in-one solution – Includes pistons, liners, rings, bearings, and gaskets in one package.

• Designed specifically for the 3406C – Every component is engineered to fit and perform correctly in Caterpillar 3406C engines.

• Restores efficiency and power – Fresh components ensure correct compression, combustion, and lubrication.

• Less downtime – One order saves time compared to sourcing parts individually.

Compression Ratio: 14.5:1

Our Caterpillar 3406C rebuild kits are available with a 14.5:1 compression ratio, which is a key factor in how the engine performs.

A 14.5:1 ratio offers:

• Strong power output for demanding marine and industrial work.

• Efficient combustion, helping reduce fuel consumption.

• Improved cold starting, even in harsh operating environments.

This balance of efficiency and power makes it the ideal compression ratio for a rebuilt Caterpillar 3406C.
