Can anyone tell me what I should torque the hub to on my A-75 (the retaining piece that threads onto the engine crank)? I've searched the continental engine manual and can't find this value.

Also, since there is no nut or bolt on this piece, is there an easy way to make an adapter that will allow me to use my torque wrench on the hub? How is the hub typically torqued onto the engine? I don't have access to a welder to make an adapter.

Thanks!
