With as much torque as you need, the tool is the best way but it can probably be done by leaving the bike on the ground (in gear) and having someone stand on the rear brake while you tighten it (please note, I said probably). I don't have the torque specs in front of me, 162 is about 220Nm which I'm fairly certain is the right torque for that bike. Use loctite on it though, the good high temp stuff.
