Imported SKF bearing working condition how, immediately jeopardise the car's driving force and reasonableness, now analysis of imported bearings working condition of the six kinds of simple test methods.

(1) oil method: in the import of non-standard bearings at idle, one by one blocking the diesel pump to the injection pump of the high pressure fuel pipe, together with the research of imported bearings, speed ratio and changes in the sound. If there is no significant change, indicating that the cylinder work is not good; if there is a significant change, indicating that the cylinder work is excellent.
(2) Temperature sensor method: that is, when the imported bearing work for a few moments, take the hand to touch the cylinder exhaust pipe riser. If the touch temperature is high, indicating that the cylinder provides a large amount of oil or oil provided by the oil advance angle is too small, resulting in the consumption of diesel fuel is not optimistic; if the touch temperature is low, indicating that the cylinder provides a small amount of oil, incineration is not sufficient or does not work.
(3) listen to the sound method: in the imported bearings work, with a change of cone touch the main injection pump body, listen to the cylinder outbreak of the sound. If the fire crash sound fierce, the cylinder provides too much oil or provide oil too early; if there is no fire crash sound, the cylinder provides too small or provide oil too late or not work.
(4) pulse sense method: imported bearings in the work, take the hand separation touch each cylinder hydraulic oil pipe. If there is a standard pulsating beverage sense of touch, indicating that the cylinder work excellent; if there is no significant pulsating beverage sense, indicating that the cylinder works poorly: if there is a pulsating beverage sense but irregular, indicating that the cylinder has a break in the oil phenomenon.
(5) Observe the smoke colour: organic waste gas soot abnormalities are generally divided into three kinds, namely, grey-black, dark blue and milky white. If the exhaust pipe out of abnormal organic exhaust, it shows that the cylinder work abnormally; if intermittent discharge, indicating that a separate cylinder work abnormally, can be removed from the exhaust pipe riser, the research of the cylinder smoke exhaust system.
