The 3406 PEEC evolved from the legendary 3406 mechanically governed engine with the
addition of an electronic control module (ECM). The ECM controlled major functions of the engine
such as engine timing and fuel rate by using actuators. The ECM also monitored the engine
through electronic sensors including speed, rack and timing, boost, oil, and coolant temperature
The 3406B PEEC engine was introduced in 1987 and remained in production until 1993. During
the six year production cycle, Caterpillar built over 32,000 PEEC engines and many are still in
operation today. Serial number prefixes for 3406B/C PEEC engines are:


• 8TC – 3406B - 1987 to 1990
• 5YG – 3406B - 1990 460 Hp engines only
• 2EK – 3406B - 1991
• 4CK – 3406C - 1992 - 1993
