The original is a 10.9 (the metric equivalent of 8). Yes, I'll not go lower than that. OTOH if the bolt were to be highly stressed again, I would rather the bolt break than the female threads in the crank be damaged, so I'm going to call the 10.9 optimal and not even consider a 12.9.
Considering the awkward location for drilling, I think I'll turn a bushing on my lathe to keep the drill centered and straight. Just about any material will work for a 1 shot tool. 1018 CRS machines easily. -----Original Message----- From: Mercedes [mailto:mercedes-boun...@okiebenz.com] On Behalf Of Richard Hattaway Sent: Monday, August 12, 2013 6:13 PM To: Mercedes Discussion List Subject: Re: [MBZ] 240D Mystery Bolt????- UPDATE I think I might ask one of the on site vendors about sourcing the bolt.
