0 445 120 086 Common Rail Injector 612640090001 for WEICHAI WP10 JAC HOWO FOTON

Installation Process of 0445120086 Common Rail Injector

1. Ensure Component Cleanliness
   Prior to installation, thoroughly clean and dry the components of the common – rail injector and the cylinder head seat holes. Components such as the injector nozzle assembly, intermediate body, pressure – regulating spring, and control valve can be cleaned using an ultrasonic cleaner. After that, wipe them again with alcohol, and finally immerse them in filtered National III diesel fuel or special pump – calibrating oil.
2. Mind the Installation Sequence
   During assembly, first clamp the injector body vertically upwards. Insert the control valve and keep it vertical. Then place the intermediate body, pressure – regulating spring, and injector nozzle in sequence. Install the nozzle cap. Use a specialized tool to press the injector nozzle down firmly until it reaches the bottom. Initially, tighten the cap by hand, and then use a tool to further tighten it to the appropriate torque.
3. Guarantee Installation Accuracy
   When installing the injector, ensure its close fit with the engine intake system. If necessary, use a dial indicator to measure parameters such as the clearance and lift of the solenoid valve.
4. Tighten with Uniform Force
   When installing the nut, ensure that the tightening force is moderate, uniform, and reliable. Operate in accordance with the torque specified by the manufacturer to avoid over – tightening or under – tightening.
5. Connect Related Components
   Properly install components like the return oil pipe and the solenoid valve plug to ensure they are securely connected without any looseness or leakage.

How to Determine the Appropriate Common Rail Injector Model for Your Vehicle?

1. Check Vehicle and Engine Identifications: The vehicle nameplate is usually located on the side of the driver’s door or in the engine compartment, which contains information such as the vehicle model and engine model. The engine itself also has model numbers, serial numbers, etc. All these can help you determine the suitable common rail injector model.
2. Refer to Vehicle Documents: The user manual will clearly indicate the applicable common rail injector model and other parameters. Technical drawings, maintenance manuals, and other materials of the vehicle can also provide relevant information.
3. Consult Professionals: You can consult car dealerships or 4S stores, as well as auto repair technicians, who are familiar with vehicle parts. You can also directly contact the engine manufacturer or supplier to obtain the most accurate model information.
4. Refer to Online Resources and Parts Catalogs:
5. Consider Special Vehicle Requirements: If the engine has been tuned or modified, you need to select an injector according to the parameters after modification. If the vehicle often operates in special environments such as high – temperature or high – altitude areas, or under special working conditions such as heavy – load or off – road driving, you also need to choose an injector with corresponding characteristics.
