Alternator belt pulley

[French4ever]

So got my alternator here with the belt pulley fitted but I'm trying to seperate the alternator from the belt pulley.
Any idea how to get it off as all it's doing is spinning :( thanks

Impact gun.

Or an oil filter wrench with rubber strap, like this... http://www.toolstop.co.uk/draper-24362-diy-ofw-diy-series-100mm-oil-filter-strap-wrench-p62237

Clamp the spline in a vice,then use a socket with a long handled ratchet,or breaker bar.
