    Torque Value

    I installed Hepco & Becker crash bars and need an important piece of information to finish the job. What is the torque specification for the lower bolts that secure the bar to the engine case? Anyone have a service manual to reference?

    Thanks,

    If you refer to this in the attached image, in the Honda fenders, it is 27 Nm.

    Thanks Oskar, thanks Max2007. The diagram with the tornillo Embridado bolt is the correct bolt. Referencing Max2007’s diagram, the torque specification appears to be 54 N-m (Newton metre). Anyone care to confirm the 54 N-m torque value before I put a torque wrench on the bolt?

    Thanks,

    I was looking at the Hepco & Becker instructions and I see that it is not the same as the Honda presses, replacing the original screw with a longer one, as it seems that it is as Mad2007 indicates. Funbobby I dare not give you some advice.

    This was Hepco & Becker's worthless reply to my email concerning the torque value of the M12 engine guard bolt: "If the bolt installs in a spot that an original bolt was, you will want to find the torque spec through the service manual for your bike. This will be the surest way for an accurate torque." If I had a service manual, I wouldn't be asking the question.  :230:

    I spoke to a machinist acquaintance and he determined the engine guard M12 bolt had a strength class of 10.9 which equates to a 54 Nm torque specification for a steel screw into steel threads. The M12 torque specification into aluminum threads is 45-60 Nm. Thus, 54 Nm is the torque value I'll use.
