Description

Dual Mass Flywheel (DMF) Movement

When a clutch is changed, it is important to test the free play in the arc springs that are within the DMF. To do this you need to rotate the DMF clockwise until you feel the spring. Mark the DMF on the teeth and then rotate anti-clockwise until you feel the other spring and then make a second mark. The gap between the 2 marks is the free play. This can be measured in ring gear teeth, or in degrees. The correct tolerances can be found on RepXpert.com, at FPS, or by calling LuK Technical on 08457 001100.

Note: The object of this exercise is not to see how far you can turn the DMF as this is simply a test of how strong the person doing it is!

For accurate testing, the DMF tool should be used, and if the DMF has a Friction Control Device fitted, you will only be able to test the DMF with the tool.
