Any tricks for getting the crank pulley off without removal tool?

So, having taken the wheel off and the inner arch cover to get access to the crank pulley, the big bolt in the centre of the pulley is off. The pulley is well jammed on though, and I can't shift it. I haven't got access to a pulley removal tool at the moment, so does anybody know how to get the pulley off without the tool? Can I use 2 bolts through the small holes in the pulley? Anybody know what size I need?

Cheers

Bolts are 6mm but seriously I wouldn't use them as you'll end up damaging chain cower... You could try to stick couple of big screwdrivers behind pulley and tap centre bolt with hammer but this might  end not very  well too. I'd look for something like this

^ Yeh a not very tight pulley can come off by hand if wiggle side to side while pulling but a tight one won't.
Just a case of some come off easy & some don't.
I've come across pulleys on military & industrial equipment that even 10t hydraulic pullers have struggled with.
On the R a bit of release oil (not wd40 5hit) & basic mechanical puller is all that needed. F00king around with screw drivers & pry bars can work but it can also crack your pump housing so be warned & also realise a cheap puller is about £8 & shipped to your door in 24hrs >

Glad you got it done, I found the trick is to go slow and not expect the pulley to come off in one go, I destroyed the first one I ever took off. Joys of being a novice back in the day.
