When performing any work on the diesel engine power supply system, cleanliness must be observed.
1. We tell you how to disconnect or connect the power wire to the injection pump or preheater, you must turn off the ignition.
2. Disconnect the battery only after turning off the ignition. Please note that disconnecting the battery will remove the security code that your radio may have.
3. Before starting work on the power supply system, ensure that the workplace is clean. If these works are carried out outdoors, then this is possible only in calm weather to prevent dust from entering the parts of the power system.
4. Clean all union nuts before unscrewing them.
5. Lay all removed parts on a workbench or other surface and cover with paper or plastic wrap. Do not use fluffy rags.
6. If the installation of the removed parts will be made only after a certain time, then these parts should be covered properly or placed in lockable boxes or boxes.
7. Before installing the parts, check again that they are not dirty.
8. Do not use compressed air to clean parts if the fuel injection system is open.
9. Do not wash the engine with the fuel injection system open.
10. Do not move the vehicle if the fuel injection system has been removed.
11. Make sure that diesel fuel does not get on the cooling system hoses. If fuel gets on the hose, it must be immediately wiped with a rag. Hoses exposed to diesel fuel must be replaced.
The high-pressure fuel pump is not subject to repair or overhaul and, in the event of a malfunction, is replaced as a set with an identical one from the exchange fund of the workshop or with a new one.
To control the fuel injection of the injection pump, as well as to remove and install it, special tools are required. The injection pump can only be adjusted in a workshop where the necessary equipment is available. In addition, experience is also required to adjust the injection pump. If the high pressure pump is removed on your own, it is recommended that you follow the instructions for replacing the toothed belt so that the high pressure pump can be released and removed.
