The Cummins diesel engine should be operated, or the flameout shaker allows the diesel engine to be in a cooling state. When the water temperature drops to about 40 ° C, the cooling water is slowly added. Be careful not to add cooling water immediately, otherwise the Cummins diesel engine is deformable or crack due to the plummet of local temperatures.
Cummins diesel engine fault omen's four: broken axis
We often ignore the vague cracks produced by the Cummins diesel crankshaft axle shoulders. In fact, with the constant exaggeration of cracks, the engine crankcase will have a dull knocking sound, and the speed is accelerated, and the sound of the knock will be aggravated.
