Diesel Power Holland successfully completed the rebuild and delivery of a Caterpillar 3406 DI-TA marine generator set for a marine customer. The project involved a full rebuild of the engine and generator package, followed by load testing at a Caterpillar-certified test bench before delivery — ensuring the unit was ready for immediate service upon installation.

About the Caterpillar 3406 DI-TA

The Caterpillar 3406 DI-TA is a six-cylinder, direct injection, turbocharged and aftercooled (DI-TA) diesel engine with a long-standing reputation in marine auxiliary power applications. Its compact footprint, proven reliability, and wide availability of spare parts make it a practical choice for vessels requiring dependable onboard power generation.

The 3406 series has been used across a wide range of marine platforms — from workboats and fishing vessels to offshore support craft and inland shipping — and remains a common engine in the global used and rebuilt marine engine market.

Project Specifications

The Caterpillar 3406 DI-TA marine generator set delivered by Diesel Power Holland was built to the following specifications:

• Model: Caterpillar 3406 DI-TA
• Prefix: 1SS
• Power output: 344 kW @ 1,800 rpm
• Generator: Caterpillar SR4 – 450 frame
• Starter: Electric starter
• Cooling: Jacket water pump
• Control: Standard CAT instrument panel
• Fuel system: Double-walled fuel lines
• Governor: PSG Governor
• Testing: Load tested at Caterpillar test bench

The use of double-walled fuel lines and a PSG governor reflects the marine safety and performance standards this unit was built to meet. Load testing at a Caterpillar test bench prior to delivery provides documented confirmation that the generator set performs to specification before it leaves our facility.

Rebuilt and Ready for Delivery Worldwide

Every marine generator set that leaves our workshop in Moerdijk, the Netherlands, goes through a thorough rebuild and quality control process. We source parts from our stock of over one million Caterpillar components, and all work is carried out by technicians trained to Caterpillar service standards. Once complete, units are load tested and prepared for worldwide transport, including all required export documentation.

For marine operators and fleet managers, this means you receive a generator set that has been independently inspected, rebuilt, and verified — not simply sold on as-is.
