Typical defects of bearings
Bearing failure can occur because of a lack of greasing, presence of a dirt or other alien particles, an engine or corrosion overload. Irrespective of the reason of failure of the bearing, it should be eliminated, before the engine will repeatedly gather.
At survey of bearings remove them and spread out in the same order in what they have been established on the engine. It will allow to define a corresponding neck of a cranked shaft and will facilitate search of malfunctions.
Alien particles can get to the engine various ways. Metal particles can be in engine oil as a result of normal deterioration of the engine. Small particles together with engine oil can get to bearings and easily take root into a soft material of the bearing. The big particles, getting to the bearing, will scratch the bearing or a neck of a cranked shaft. The best prevention of failure of the bearing for this reason: carefully clear all internal surfaces of the engine and keep them clean at engine assemblage. Frequent and regular replacement of oil with the filter Is recommended also.
Insufficient greasing of necks of a cranked shaft can be caused the different reasons, such as an oil heat, an overload of the engine and oil leak.
The manner of driving by the car also influences durability of the bearing. Completely open throttle заслонка at low turns of the engine creates high loading on bearings and expression from a zone of contact of an oil film. These loadings lead to occurrence of cracks in a working part of the bearing that weakens the bearing and can lead to a separation of an antifrictional layer from a steel basis.
Movement on short distances leads to corrosion of bearings because the engine does not leave on the stabilised working temperature at which water steams and corrosion gases leave. These steams and gases, being condensed in engine oil, form acid and a deposit. Acid together with engine oil gets to bearings, and corrosion of bearings begins.
Wrong selection of bearings at engine assemblage also leads to failure of bearings. The bearings established with a preliminary tightness, leave an insufficient working backlash of the bearing therefore decreases or there is no butter layer for greasing.
