Engine belts need to be replaced periodically, but how to install them is a problem. Let me popularize it.
Timing belt installation
The installation of the engine belt requires a certain technique: after making the ignition marks of the crankshaft and camshaft, hang the belt on the crankshaft wheel, and by the way, from the opposite side of the tightening wheel straight upward paddle hanging on the camshaft wheel, and then after that fold the belt into the side of the tightening wheel, and hold up the tightening wheel can be.
Tighten or loosen the timing belt
The tightness of the timing belt is significant, if it is too tight, the tension is too large, it easily leads to breakage, affecting the life of the belt; therefore, after the timing belt is installed, it is necessary to adjust the tightness, adjust to the belt pressed down to have a 10mm looseness, and can be turned over 90 degrees. If the belt can not be pressed down 10mm, the timing belt is too tight.
It should not be too loose or too tight
In addition, if the timing belt is too loose, it is easy to slip, resulting in the configuration of the timing lag, resulting in the car appearing shaking, refueling powerlessness, lack of power, increased fuel consumption, etc. In the engine load or power shock is also easy to jump teeth, which may lead to the top of the valve, which will damage the engine. Usually, one should regularly check the use of the belt, and check whether the elasticity is appropriate, if too loose or too tight, should be adjusted promptly; in addition, one also needs to check the belt surface whether there are cracks, or teeth with or without wear and tear, if the wear is serious or cracked, it should be replaced promptly, to avoid breakage.
