What happened to the car's 1000 rpm trembling?

The best solution is to completely replace the clutch disc pressure plate and the rear flywheel, but it is very wasteful.

The general treatment method is to replace the clutch plate and pressure plate. At the same time, there are three contact surfaces when the flywheel and clutch work, one is the flywheel, the other is the pressure plate, and the third is the gift box device plate sandwiched in the middle. As long as one contact surface is flat, it will start to shake after a period of use, especially when the idle speed is low, and the idle speed of cold cars is generally high, so the contact force is strong.

You need to check whether the idle speed of the hot car is low and whether the throttle and idle motor have not been cleaned for a long time.

The other is to change the pressure plate. The polished flywheel can completely solve your problem. If the separation bearing chamber or the hairpin is noisy, it is not necessary to replace the clutch plate at the same time. It is very simple to judge whether there is noise in the release bearing. Step on the clutch or neutral for half a step. If you can hear the rustle of the gearbox, you need to replace the release bearing.

If the shaking is not very severe, it will not affect the driving of the vehicle, mainly because the service life of the clutch plate will be reduced and the vehicle will not be damaged.
