How to install the engine belt, how to judge the timing belt is too tight

The engine belt needs to be replaced regularly, and how to install it during replacement is a problem. The installation of the engine belt requires certain techniques: align the ignition marks of the crankshaft and the camshaft, hang the belt on the crankshaft wheel, and hang it on the camshaft wheel from the opposite side of the tensioner, and then fold the belt. Enter the side of the tensioner and hold the tensioner tightly.

The tightness of the timing belt is very important. If it is too tight and the tension is too large, it will easily cause breakage and affect the life of the belt; therefore, after the timing belt is installed, the tightness needs to be adjusted until the belt is pressed down to 10mm looseness. , It can be turned 90 degrees. If the belt cannot be pressed down by 10mm, it means that the timing belt is too tight.

In addition, if the timing belt is too loose, it is easy to slip, causing the configuration timing to lag, causing the car to jitter, refueling weakness, power shortage, fuel consumption, etc., and it is easy to jump teeth when the engine load is large or the power is impacted. It will cause the valve to top up, thereby damaging the engine. Normally, check the usage of the belt regularly to check whether the tightness is appropriate. If it is too loose or too tight, adjust it in time; in addition, check whether the belt surface is cracked and whether the tooth shape is worn. If it is severely worn or cracked, it should be Replace in time to avoid breakage.
