So I brought the center (pivot/pinch) bolt to work to check the size and to get a helicoil kit for it and suddenly it came to me that maybe I did tighten the bolt and this has been an issue before. Most posts here talk about the "19mm bolt", but mine does not take a 19mm socket. It does however sport a better hex allen, say around 10mm. This leads me to wonder if it happened before and someone else put in a longer/larger bolt.

This may now explain why the bolt was a little too large for the tensioner hole. With little filing of the hole, the bolt fit fine, but I blamed it on the part manufacturer for not sizing the hole correctly. So, it seems I may have cast blame where I shouldn't have, unless MB used something other than a standard hex cap bolt.

Can anyone confirm the stock measurements for the original bolt?

Help is appreciated. Thanks!
