12A Torque spec for front cover pulley

I am putting the front cover of my 12A after changing the o ring from the front oil pressure regulator and i would like to know the torque spec of the front pulley as I don't want to prematurely wear out the front sealing.

I believe it's around 85 lb/ft or 115 Nm.

Before removing the pulley get something to keep the clutch pedal pushed down so the front thrust bearings don't get out of place:

The bottom of that page also lists seals and gaskets you'll want to replace when you take off the front cover.
