Attention!
- Check the fuel supply pressure in the engine mode - idle.
- Dispose of escaping fuel.
Checking the fuel supply pressure must be carried out in the following order. Prepare fixtures «13.5.222» And «13.5.270», protect the generator from pollution and connect «DIS tester».
Connect fixtures «13.5.270» And «13.5.222» between themselves (pic. 6.117) into a single assembly. Open quick shutter (1) supply pipeline (2). Connect sensor (3) pressure (up to 3.5 bar) to adaptation «13.5.222» and the corresponding conclusion «DIS tester». Insert fixture «13.5.270» between pipelines (1) And (2).
Start the engine, bring it to a stable idle mode and fix the fuel supply pressure from the fuel pump to the HPP, which should be in the range of 3500–7000 mbar.
Rebuilding the engine should be carried out in the reverse order, while it is necessary to turn off the engine, remove the tool assembly and connect the hoses. To remove air from the power system, it is necessary to turn on the ignition for about 1 minute. During this time, the fuel priming pump is activated and the fuel cooler is filled with fuel, forcing air out of the system.
