2.2 cleanliness bad oil

As mentioned earlier, oil contains too many impurities will expedite the bearings and shaft wear and tear, often found in the maintenance of the engine oil sump black, thinning, and even Muddy to be black, such as oil continue to use cents Bearing no doubt will in a short time due to wear and tear scrapped.

Supercharger oil from the engine of the pump, pump if the machine does not work normal, resulting in insufficient supply or low oil pressure, as well as tubing into the road deformation, obstruction, the occurrence of cracks caused phenomena such as inadequate supply of oil, can the turbocharger bearings and shaft damage due to poor lubrication. Often found in the maintenance of bearings and shaft are some obvious signs of dry friction, will see serious burning blue phenomenon. Therefore, to carry out regular checks into the tubing Road, and remove problems.

Supercharger oil imports should be greater than 0.2 MPa pressure to ensure the supply of oil and rotating parts such as bearings normal lubrication. In addition turbocharger rotor inspection, if the axial gap too large, then the thrust bearing wear too large. If excessive radial clearance, the floating bearing wear too large.
