Frigidaire Washing Machine drive pulley screw removal

I am trying to remove the screw that is holding drive pulley and drum for my Frigidaire ATF7000FS0.
#29 of [picture for this parts](http://www.********************************.com/partsdirect/part-model/Frigidaire-Parts/Washer-Parts/Model-ATF7000FS0/1428/0153200/R0703104/00003?blt=06&prst=&shdMod="]this diagram[/URL]

I am using the metric hex wrench and it does not budge (even hex wrench was slightly got bent.)
From the [URL="http://www.appliancepartspros.com/frigidaire-screw-134408400-ap3844436.html), I’d need to turn counter-clock-wise.

what would i need to use/do? I did WD40, tapping with hammer, etc…

Any help is appreciated.
