Hi
If you own a 1/4 drive socket set you can use it to undo the square head bolt.
Using them extension bar, put the "female" end onto the square bolt, then use a 8mm socket on your ratchet which is a good fit on the "male" end of the extension to undo.
From memory, yes it is a right hand thread.
Also when you put the crank back together you'll need to make a tool to centralise the two crank halves, if you've nothing else to hand a piece of ground down broom handle will do the trick.
