Yes. To rotate the brake torque arm, just loosen off the lock nut on
that side, rotate it to where you need it to go, then make sure the
L/H cone is tightened correctly (finger-tighten it gently then loosen
off a quarter turn) then tighten up the lock nut again.
I find it quite difficult to gauge exactly when the torque arm is in
the right position, so it's probably best to do this with the hub in
situ on the bike if you at all can. You'll need a 17mm lock nut
wrench to do that though, and whether you will have space to get the
wrench in there depends on the shape of your rear triangle I expect.
I've not tried it myself yet so have usually done this adjustment off
the bike then found it to be wrong and had to retry a few times to get
it right. I've only just bought the 17mm lock nut wrench myself in
the hope it will be easier for me next time.
I find doing it off the bike it helps to line up a steel rule against
the flat side of the axle so you can see easily exactly how the torque
arm lies relative to the plane of the axle flat. Do this before you
loosen anything off so you can note exactly what your starting point
is and work relative to that.
I hope that makes sense. You'll find a helpful video entitled "hub
gear with brake" showing how to do this in the Technical section at
