© 200416 6-1 Cleaning BE ENGINE FUEL SYSTEM ΛΦ45/55 series 4 2 6. CLEANING 6.1 CLEANING INJECTOR The injector must never be cleaned with a steel brush or pressure cleaning equipment. Never put the brush in the injector bores when cleaning the exterior of the injector nozzle. If this happens, the nozzle must be replaced. Before cleaning the nozzle, cover the injector bores. Only clean the injector with a brass hand brush. Note: The use of steel brushes can cause deformation of the injector bores, with the result that the wrong amount of fuel is injected. This deformation cannot be ascertained by measurements or checks. Note: The disassembly and assembly of injectors is not permitted. Only external cleaning is permitted. 1. Remove the injector. See "Removal and installation". 2. Clean the injector hole in the cylinder head. The metal surface of the hole must not be damaged. 3. Wipe the exterior of the injector with a clean, lint-free cloth. In the case of heavy soiling the injector may be cleaned carefully with a brass hand brush (not the apertures in the injector nozzle!). 4. Fit the injector. See "Removal and installation". } M2 00 040 i 400413 |
