The counterweight is the cause of a lot of the marble sound that comes from the MT82-D4. Don’t believe me, crawl underneath your car and give it a wiggle by hand.I was able to try around again today.
The violent vibrations at the first attempt had its cause in the too small distance between NVH damper and bracket.
Have today mounted without NVH damper, which were then the marble noises described by blowfish for 10% of the users.
With the NVH damper are again somewhat less, but I will not get rid of them completely.
So it should be official that my MT82 belongs to the 10% with marbles inside.
