the majority of the domestic automobile clutch closed lateral ball bearings, the choice of grease most of the calcium-based grease, sodium and calcium based grease. Most of the maintenance staff in the implementation of the separation of bearing lubrication, melting after separation of oils and greases, 50% heating oil immersed bearing into the cook, it filled and then the way of cooling. Although such an approach to complete the filling task, but ineffective, because the heating will make the organizational structure of calcium-based grease damage, grease lubrication performance, resulting in separation of premature bearing wear and shorten its life. The correct way is to raise conduct filling.20. Luxury cars must use imported oil
Some car owners and Vehicle Administration staff, the high cost of luxury cars, and the quality of imported lubricants, the use of imported oil is safer, more secure. In fact, the evaluation of lubricant quality is good or bad not to see the strength of its advertising, but depends on the quality indicators, and actual results. The domestic market, sales of imported lubricants most foreign companies with our joint venture to produce, most of these lubricants to the use of domestic base oil, combined additives in the production of domestic blending, the Great Wall lubricant made ??of quality basic oil, imported additives compound blending in the domestic production, the quality of their products passed the ISO9002 international quality certification. The luxury car should be based on their working conditions and technical specifications, technical performance of the selection of the appropriate quality of domestic oil or imported oil, while the spread of domestic and imported oil is self-evident.
