There are 7 reasons for the failure of the engine for LG6300 excavator.
The 1 engine single pump gasket is too thick or too thin.
2 the mechanical oil pump is worn or damaged.
The 3 single body pump is not in place.
The 4 oil bolt (also called the overflow valve) is not tight sealed.
5 LG6300 monomer pump plunger wear is serious.
6 starting and thickening solenoid valves have problems.
7 LG6300 injector installation misplacement.
Fault analysis of engine for LG6300 excavator is difficult to start.
The thickness of the single pump gasket of the 1 Deutsch BFM1013 engine is too thick or too thin, which may cause the fuel injection advance angle of a cylinder to be incorrect, and the engine will start trouble.
The 2 Dao yutzi BFM1013 engine oil pump has excessive wear or leakage, such as leakage and so on. The low pressure oil circuit may have a failure of pressure. Therefore, the working LG6300 excavator deutt BFM1013 engine requires pressure of low pressure oil path in the 0.3~0.5MPa range.
3 single body pump installation error. (the position of the single pump speed gear rod is in the position of small oil or the position of oil breaking, the fuel supply of the engine is insufficient or no oil supply at all, resulting in the difficulty of the engine starting of the excavator). The 4 oil bolts are not sealed or damaged, and the low pressure oil road can not establish enough pressure. The engine starting difficulty is unavoidable.
5 single body pump plunger wear seriously, the engine has a shortage of oil supply and oil supply pressure, the engine starting difficulty is a very normal thing. In addition, because of the single pump plunger wear, the engine will also appear the following phenomenon:
Lack of power.
The engine may smoke black.
6 starting and thickening solenoid valve damage.
7 deutt BFM1013 engine injector installed misplacement.
