Misunderstanding of car maintenance

In real life, some driver in the car maintenance is often taken for granted, which entered the errors were unable to extricate themselves, but anti-outsmarting themselves appropriately, resulting in engine damage, or machinery caused the accident. Mistakes 1: The car maintenance bolt tight as possible. Car with bolts, nuts connect the many fasteners, should ensure that they have sufficient preload, but not a hard twist. If a hard twist, on the one hand will allow external connectivity of the role of permanent deformation under the other hand will have a tensile bolts permanent deformation Preload fall, or even withholding or broken slip phenomenon.

Mistakes 2: Oil better car maintenance. When the engine sump oil shortage, such as friction bearings and crankshaft will be less due to oil and lubrication of the poor increased wear, and even trigger a bearing burning incidents. In fact, if too much oil, the engine crank handle at work, the link will have a dramatic reading of the agitation, not only increased the internal engine power loss, but also due to the cylinder wall Jiaojian oil increased, so very easy Pai burning oil produced fault. Therefore, the engine oil sump of oil should be controlled in the feet, under the carved lines between the good.

Misunderstanding 3: the transmission belt tight as possible. Automobile Engine pumps, generators use the triangular belt transmission. If the transmission belt adjustment hard, and easy to produce tensile deformation At the same time, car maintenance and pulley bearings easily lead to bending and damage. Transmission belt tight in the general press should be adjusted to the central belt, and its sinking both ends of the pulley from the centre of the 3 to 5 percent better.
