    Torque spec for s52 main caps?

    I need the torque specs for an s52 main cap in lb/ft. I read some where that the it is 50 NM, but my torque wrench's NM is in smaller numbers.

    thanks

      Centernet isnt working right now, for some reason, but that sounds right. It isnt much, at all. I want to say that the angle torque was actually a 35*, but I cant be positive without my "official info".
