Separate question, how do people know that their FW is worn out and they need a new FW? My Boxster has 59K miles on it. To me the FW looks pretty good. Also With the EV I am not going to be shifting much and hence the FW (and Clutch) won't wear down as much. How do I make sure that I have reasonably ok FW? If I post some pictures, could someone who knows this stuff make out or it has to be physically examined?
Sorry of my questions are real basic...  |
Try a better balancing shop. In any case, even lower RPM balancing is better than not.
There is a standard factory test for the dual mass that measures twist of the elastomeric component. Porsche has released a Technical Service Bulletin on checking the dual-mass flywheel (TSB 911 8/02 1360). Basically, you are looking for a maximum of 15MM movement between the segment's.
Here is the bulletin for the 996, which is basically the same:
