Cummins 4022914X Injector Hold Down Clamp

The Cummins 4022914X injector hold down clamp is a critical fuel system component designed to secure the fuel injector within the cylinder head bore. It maintains the required clamping force to ensure proper injector seating, sealing, and alignment under high combustion pressures. This clamp is engineered for Cummins M11, ISM11, and QSM11 series diesel engines displacing over 10.8 liters. Manufactured from high-strength alloy steel with heat-treated surface finish, the clamp resists fatigue and corrosion in heavy-duty operating environments. It replaces Cummins OEM part numbers 4022914 and 3883144. The component is sold individually; six clamps are required per engine for the six-cylinder M11/ISM/QSM platforms. Installation requires specific torque procedures per Cummins service manual to prevent injector leakage or damage. This part is applicable across construction machinery, heavy-duty trucking, and industrial power generation equipment utilizing the specified engine platforms.
