Caterpillar 3408C Engine Overview
The Caterpillar 3408C is an eight-cylinder V-configuration, four-stroke diesel engine within Caterpillar's established 3400 Series.
The wider 3408 platform includes:
- Caterpillar 3408
- Caterpillar 3408B
- Caterpillar 3408C
The 3408C represents a distinct generation within this V8 engine family.
Caterpillar continues to maintain dedicated parts information for the 3408C Marine Engine, including serial-number-based parts identification.
Individual 3408C configurations can differ according to:
- Engine serial number
- Serial-number prefix
- Arrangement number
- Engine rating
- Fuel-system configuration
- Turbocharger arrangement
- Cooling system
- Electrical equipment
- Vessel installation
- Production revision
For this reason, 3408, 3408B and 3408C parts should not automatically be treated as interchangeable.
