2, diesel engine is often overloaded with work.
3, in the light of the crankshaft, the crankshaft to the crank arm of the transition fillet grinding too small.
4, the crankshaft using a long time to cause fatigue operation.
Second the cause of the failure of the crankshaft bending
1, diesel engine is often overloaded with work.
2, Baotou North Benz accessories main shaft bearing clearance is too large or the uneven wear of the bearings.
3, the combination of the crankshaft assembly is not correct.
4, the diesel engine cylinder accident occurred.
Third, the cause of the failure of the crankshaft journal wear
1, Baotou in the northern parts of the crankshaft of the crankshaft of the individual oil channel instantaneous blockage or oil pressure is too low
2, the oil can not be replaced for a long time, more internal impurities.
