Hey guys, I'm planning on installing a harness in a friend's R56. Does anyone know the socket size and bolt torque on the front and rear seat belt anchor bolts? I don't have an R56 Bentley manual. Thanks!
OK & the answer is T50. At least that is the size on Babs Clubster which I assume is the same. If you need a good set of torx bits NAPA sells a nice set of impact bits. They call them star bits. About $38 or so.
Yes.... on the torque question.... Its a M10 bolt used at all three locations: set at 36 Nm (27 ft-lb) the seat belt anchor to body the seat belt reel to B-pillar the seat belt to B-pillar With a note to use Locktite with new bolts. It doesn't give the torx bit size to use though.
Cool, thanks guys! I have a T50; that's the same as the bolt on the R53. I thought the torque was going to be a bit higher, but that's cool. I can do 27 ft-lbs by hand.
Thanks for the equation and the torque spec. I decided to just do it by feel because I packed the big torque wrench that starts at 25 ft-lbs, it wasn't too bad. :fingerscrossed: The hardest part is keeping the buckles from rotating too much when you tighten the bolt. New harnesses come with a new bolt and washer that eliminates this issue, but these were used equipment so I reused the stock bolts. Cutting the plastic off was easy, definitely required a Dremel, and had zero structural impact on the integrity of the buckle.
