Clutch DCT250 balancing with flywheel

Imbalance is one of the most dangerous phenomena that affects all rotating parts in a car. For any rotating part, for one reason or another, the center of mass is not on the axis of rotation, but is shifted from it by a distance. In this case, there is an imbalance. When the part rotates, centrifugal force will occur, which causes vibration. Therefore, from a theoretical point of view, balancing consists in creating an unbalance in a part that is equal in magnitude (modulus) and opposite in sign to the original imbalance. The sum of these imbalances (the resulting imbalance) will be equal to zero, which means that our part is balanced, and there will be no vibration during rotation.

How to understand after repairing an automatic transmission that the problem is in clutch balancing? The main symptom is vibration at idle.

There are two ways of balancing: static and dynamic. We use dynamic balancing. The DCT250 clutch (with flywheel) is balanced on a special balancing machine.

• We connect the clutch and flywheel using a centering mandrel
• The clutch with the flywheel is installed on a balancing machine.
• We set the necessary values ​​​​in the system and balance to the desired result (1.5-2g at 800 rpm)
