I reached out to Hewland for torque values on the gearbox since Radical doesn't have them in their manual.  Here is the picture I sent

Gearbox Picture

And here are the values:

Blue arrows = Studs (STU-036) into the maincase     = 12Nm

        = Nuts (NUT-004) onto stud (STU-036)  = 31Nm

Red arrows = Studs (LD-201-2) into the maincase     = 12Nm

        = Nuts (NUT-004) onto stud (LD-201-2) = 31Nm

Green circle = NMT-230-1 = 163Nm

 

You'll need their reaction bar and socket to get the lock ring (green circle) off.

 

Below is the technical manual for the gearbox.
