Dual mass flywheel

Post by lorenz30 » Sat Feb 24, 2018 5:12 pm

Hello

i ordered a pico nvh Standard kit with mongoose lead. I´m very excited to play with it. My question is, can i identify a bad dual mass flywheel with the nvh kit? What would be the Vibration Levels from the engine? Thanks a lot for your answers.

The NVH Tool will idenfity a vibration that is the same frequency or some multiple of that frequency and it will display the magnitude of that vibration. It's up to you to work out the source of the vibration. The NVH Tool cannot inherently tell you what component is the cuase. If the magnitude is large enough then there is only a limited number of components on the engine that can cuase very large vibrations.
In general, for diagnosis with the NVH Tool, there is no absolute values for different components / failures. Each measurement is relative. Which frequency of vibration has a greater magnitude than all the other Known frequencies.
