Vito's +4 timing woodruff key questions

[FasterBlaster03]

Hi I recently purchased a +4 Vitos key and was wanting to know which way it is supposed to be installed on the crankshaft. I know it does have a notch and am not sure which way it's supposed to point. Also can I use an engine lock up tool to torque the nut to 52lbs? Or will that stress the bearings. Thanks blaster forum
Btw the engine lock up tool is the one where you screw it into the spark plug hole.
