Caterpillar 1106465 Fuel Shutoff Solenoid Assembly

The Caterpillar 1106465 is a 24 VDC electromechanical rack shutoff safety solenoid designed to interrupt fuel supply in Caterpillar diesel engines. It operates on an intermittent duty cycle (ON/OFF) and features a push-type actuation mechanism. The solenoid terminates in 8-32 UNC terminal threads and mounts using 1/4-20 UNC hardware. This component serves as a critical engine protection device, ensuring immediate fuel cutoff during emergency shutdown or key-off events. Cross-reference interchangeability includes Caterpillar OEM part numbers 110-6465, 6T-4122, 7N9504, and 6T4122. The solenoid is validated for fitment across multiple Caterpillar engine platforms including the 3306, 3304, 3406B, 3306B, 3406C, 3204, and 3304B series. Applications span hydraulic excavators, wheel loaders, wheel tractors, motor graders, compactors, and articulated trucks equipped with these power units.
