1.3. 051 Injector Valve Cap Installation Precautions

(1) The replacement of the injector valve cap must strictly follow the electrical system, the approved pressure of the low-pressure fuel intake system, the approved pressure of the high-pressure fuel circuit system, and fuel system replacement consumables requirements (including the low-pressure fuel circuit system filter and the high-pressure fuel circuit) specified in the vehicle engine maintenance manual.

(2) Replacement of wearing parts of the fuel system, cleaning requirements for the connection between the fuel system and the injector valve cap, the fitting clearance of the injector valve cap connection, the installation angle and tightening torque of the injector valve cap, the fitting clearance of the intake system, and the fitting clearance of the exhaust system to ensure the service life of the engine and the normal operation of the injector valve c

(3) When installing the injector valve capon the engine, it is necessary to clean the engine block, cylinder head and other parts connected to the injector valve cap, and ensure that there is no dust, carbon deposits, water, rust spots, etc.

(4) Before installing, check whether the injector valve cap washer shim has been replaced and installed on the injector valve c

(5) When installing the injector valve cap, apply lubricant between the injector valve cap, fuel nozzle sealing washer shim and O-ring.

(6) Without replacing new washer shim can lead to: deformation of the tight cap of nozzle, deformation of nozzle, deformation of nozzle orifice, oil leakage and air leakage, which will cause serious damage to the injector valve cap and nozzle to break and cause damage to the engine.

(7) When installing the injector valve capon the engine, please carefully check the components related to the installation of the injector valve cap, such as the injector valve cap pressure plate, screw, injector valve cap rod and other accessories are not deformed, and install it in strict accordance with the operation steps of the engine maintenance manual.

(8) It is forbidden to operate the bare injector valve cap for a long time in an environment with serious dust pollution and corrosion to iron products.

(9) It is forbidden to operate the bare injector valve cap for a long time in a strong magnetic field environment.
