1. Lost machine compression
The first cause of a hard-living diesel engine is loss of compression. To check the compression of diesel engines, it can be done by the diesel engine to crank slowly and press the choke. If the choke is removed and the pressure is back, the engine compression mark is still good. However, if you do not find any pressure at all, compression leaks.
2. Weak Fuel Pressure
The cause of the second hard life diesel engine is decreasing solar pressure. It can be characterized by the loss of the sound of solar radiation when the diesel engine is crank. A good sound of solar pressure will sound loud and clear at the time the diesel engine is being crank.
3. Packing Head is Broken
The Packing head is a limiting portion between the compression chamber and the head cylinder. Diesel engines that have long been not dismantled or diservise, the packing head will undergo depreciation (damaged) resulting in compression of the machine leaking when the diesel engine is hot. Resulting in a diesel engine is hard to turn on.
