High Quality Diesel injector 0 445 115 064 0445115064 Diesel Fuel Injector For Bosch Spare Part

Injection pressure adjustment screw locking nut surface roughness is not the same on both sides, such as the Luoyang Yituo series diesel engine injector, the surface roughness value of the small side should be fitted with the injector shell so that the effective contact area is large, the braking effect is good, the ability to prevent screw loosening is strong, the lock is reliable for the assembly mark porous, long porous nozzle couple parts, must be assembled according to the mark, Make the nozzle needle valve body nut mark and the injector shell mark alignment replacement without mark, generally can be assembled according to the nozzle hole position, the high side of the nozzle hole position should be positive injector oil inlet joint. It is also possible to test the injector couple with mark 1 on the injector tester and record the injection position of each hole. The unmarked couple can be assembled in this way. The metal rod slit filter element in the oil inlet joint of the fuel injector of diesel engine as well as the metal spring slit filter element of the needle valve body in the annular oil channel of the fuel injector of the diesel engine of the natural movement series should be thoroughly cleaned, and should never be removed or installed. Practice has proved that the filter element plays a certain role in preventing mechanical impurities from entering the puppet parts, extending the service life of the puppet parts and avoiding the needle valve pad. The oil nozzle tappet assembly should be inspected. If the steel ball in the tappet hole is worn, the steel ball should be replaced. If it is inconvenient to replace the steel ball or the wear around the hole is heavy, the tappet assembly should be replaced. The verticality of both ends of the nozzle spring facing the center line should meet the technical requirements.
