Series 149 Parts and Rebuild Kits


The Series 149 engines by Detroit Diesel was launched in the early 1960s.

The first configuration was a 12V149N (naturally aspirated) rated at about 600 hp (450 kW) soon followed by a 16V149N rated at about 1,000 hp (750 kW). As manufacturers in the marine, construction, mining, and power generating industries required more power output, Detroit added turbocharging and intercooling to the engine. Over time Detroit Diesel continued to further the design of the engine finally bringing the engine up to 137.5 hp (102.5 kW) per cylinder and 406 ft·lbf (550 N·m) torque per cylinder representing a considerable amount of power from 149 cubic inches (2,440 cc) per cylinder. Much of this increase in power could be contributed to DDEC III (the third generation of Detroit Diesel Electronic Controls) electronics, thermal barrier (ceramic) coating of piston domes & fire deck, by-pass valve controlled blowers and Separate Circuit Charge Cooling (SCCC) system.
