In order to check if there are difficulties with starting, whether fuel is supplied to the nozzles, loosen the union nuts at two nozzles and, without turning on the glow plugs, start the engine until fuel appears at the union nuts. Then tighten the cap nuts to 20 Nm and start the engine in accordance with the operating instructions.
Attention: When air is not automatically purged from the supply system, the following measures must be taken:
When working with the injection system keep clean.
Ensure that diesel fuel does not get on the coolant hoses. If necessary, wipe the hoses immediately. Replace damaged hoses.
Press the clip and disconnect the fuel supply line -3- at the fuel filter to the injection pump. Collect and dispose of escaping fuel in an environmentally friendly manner.
Insert a suitable hose into the threaded hole and lower its other end into the vessel.
Remove the fuel pump turnip and connect the terminals on the relay base with a jumper to the pump could supply fuel.
If fuel flows into the vessel, remove the jumper and insert the relay into place.
Connect the fuel inlet line, pre-lubricating the seals with technical vaseline or acid-free grease. Replace damaged seals. Fix the pipeline with a clamp.
Loosen the plug -1- on the injection pump by 2 turns.
Crank the engine with the starter until fuel comes out of the hole in the pump. Collect leaked fuel.
Replace plug -1- and tighten to 25 Nm.
Loosen the mounting bolts and attach the intake manifold covers.
Loosen all union nuts of the fuel lines at the injectors with a special wrench, for example, HAZET 4550. Turn the engine crankshaft with a starter until fuel comes out from under the nuts. Then tighten the cap nuts to 20 Nm. If leaks are found, tighten nuts to 25 Nm. As a result, a rapid removal of air from the fuel lines of the fuel system is achieved.
Carefully remove fuel leaking into the engine compartment.
Install the engine covers.
