ABSTRACT:
A diesel fuel injector fixture is disclosed for torquing a solenoid valve within a diesel fuel injector body. The fixture includes a hydraulic ram for partially clamping the solenoid valve to the injector body and a nesting fixture for locating the fuel injector relative to the hydraulic ram. An adjustable stop assembly on the torquing fixture adjusts to the orientation of a torque wrench engaged with the solenoid valve and locks in place to provide stops for the torque wrench. The torque wrench rotates between the stops to apply a predetermined final torque to the solenoid valve, wherein the combination of the hydraulic clamp load and the predetermined final torque properly seat the solenoid valve in the injector body.
