Anyone out there know the correct torque spec for the S58 main bearing bolts? Thanks.
Welcome to the forum. You'd have made it a lot easier to give you this information if you'd have told us the model and year of the car/engine in question. This is the way we make sure we access the correct BMW resources. In lieu of this information, I have chosen a G82 M4 coupe.
Assuming you've read the numbers from the crankshaft and purchased the correct classification bearings (green/blue/brown), the torques are:
Main bearing cap to crankcase
M10x85 11.9
Replace screws.
1. Tightening torque
25Nm
2. Angle of rotation
65°
3. Angle of rotation
65°
