Torque spec for Throttle body actuators?

[eswaroop]

Anyone kindly share the proper torque specs to use for bolting down the Throttle body actuators on the S65B40?

Did you happen to get a definitive answer to your question? I’m also looking for the torque specs and saw a post where someone estimated 7nm, which just seems low to me. Thanks.

I think I found the answer to my question... RealOEM lists the mounting bolts as M6 25 grade 8.8. According to every metric torque chart I could find, these bolts are torqued to 10nm or 7ft/lb. I used this as a guide when iinstalling the TBs and the bolts snugged up nicely without feeling overly stretched.

Whoops, and thanks. Only time will tell if my bolts snap.

OP that is close enough to the 8 NM (6 ft lb) BMW calls for. The spec link above is for the hex bolt connecting what BMW calls the "operating levers" to the two long shafts the throttle actuators move.
