05 XC90 T6 Crank pulley

I am attempting a timing belt and pulley replacement on my 05 XC90 T6 but I'm stuck at getting the crank pulley off. I can't seem to get that 30mm to come lose. Tried penetrating oil even though it shows no sign of rust. First try with cam holder I ended up causing belt to slip on crank enough that the crank moved 1/4 turn, (from 12 O'clock to 9 O'clock counter clock wise). Cams did not move.
So second try using a crank holding tool and a 2 foot breaker bar I broke the holding tool (YAY). Even used impact tool to try and get it loose.

Cant believe the tensioner roller is plastic (the cause of timing codes I was getting from it coming apart) and the replacement is also plastic. POS plastic just shattered into pieces, lucky it didn't cause belt to come off.
Speaking of belt it still looks new and bearings feel tight and smooth on tensioner. Someones dumb arse idea to use a plastic roller. Premature failure I assume.

First question, did I mess up timing position if I leave the cams where they are and turn the crank back to 12 O'clock?
and second, how do I get this nut off without possibly damaging something?

There is a tool to remove the nut but I'm not sure it would help. I tried to remove the pulley also to no avail. I used a 3' cheater bar and all it did was bend the bolts that I used to hold it in place.
I even applied some heat and that didint work.
Good luck man!

Been waiting on a buddy to bring me a bigger impact but,
I been messing around with that crank and I need definitive conformation that if belt is off and the cams are setting on their marks that the crank can turn a complete 360 deg. and not hit.
I know I couldn't have bent anything. I only been turning by hand and not once has it ever got in a bind to bend or break valves. I know the difference between compression resistance and a hard spot. I'm a supervisor in the commercial construction trade I am pretty mechanical incline. I have to be.

Well I got that pulley off. Used the starter,bumped starter with a ratchet on the nut. Watched as wife was at the key. Crank only moved about 1/4 turn once nut released.

I am about to put new belt on and I have noticed i have some play in the cams. They can rotate back and forth about 3 teeth from their marks. Is this the reason they say when setting the marks up before removing the belt, to rotate past the marks a 1/4 turn then back to marks?

Well Its Finished and RUNNING!!!! Drove it up the street and back
I was so scared it wouldn't fire up. But it did like a champ.
Its got a slight miss at idle but smooths out once above 1k rpm. and has the power I been missing, since I been having to drive the boy's Cobalt, (what a POS), last 3 months.
It runs like it did before I started this quest, so I'm guessing its still a bit off time maybe.
Might take it to Volvo to do that part.
