The Cat 3406E diesel engine marked a significant advancement in the series, coming after models A, B, and C, as it became the first to incorporate full electronic control. While it has built a reputation for dependability, it was eventually superseded by the C15 engine in a bid to comply with revised emissions regulations. Many parts can be interchangeably used between these two models. However, it remains crucial to ensure you have the appropriate part number for the component you need.
Our highly trained staff is more than just knowledgeable about CAT diesel engines and heavy equipment—they are enthusiasts, keen on providing you with the best experience possible. We do not only supply the common parts, but we also go the extra mile by offering parts that are often unavailable from dealers.
