Freelander 1 1.8K remove crankshaft driving sprocket

Hello everyone and Merry Christmas.
I am having some trouble removing the Cranksfaft/Cambelt driving sprocket, I am pulling it with some force, is there a special procedure?
I need to remove this in order to replace the oil pump/gasket.
Below is the pulley I am referring, any advise is appreciated thank you.
In the workshop manual it only says "remove it"

They're not normally tight, and often just fall off on there own. Just put a couple of stout screwdrivers behind it and lever it off.

I will try with the screwdrivers I did with one and nothing. Thanks

you need to keep it level on each side or it will get stuck

I managed to remove it however I did it like an ape. Had to use some force and now the sprocket is a bit bent in two sides, I am not sure I should use it again after hammering it to the level.
There is also the issue of not getting a replacement anytime soon... Holidays

How did you bend a powdered metal part? Can you post some pictures of the damage?

Is just the teeth pulley part, and the oil pump but I did not care about that since I replaced it. Will post pictures in the morning.
I will have to replace that for sure. There is no damage on the crankshaft or anything related. Apparently something like this would help: https://www.ebay.co.uk/itm/162003553923

Some proof of my doing

It's got dents all over the teeth, which isn't good. You'll need to smooth off any high points with a fine file and finish with fine paper, before that pulley can be reused. The rear flange should tap flat again, using a brass drift and light hammer. Alternatively get a second hand replacement, and save a lot of remedial work on the pulley.

I already ordered a brand new one for 29 quid. However the problem that I have is the car now has to be parked until I will receive it.
Was only thinking of using this temporarily but even that is dangerous. I guess is a price to pay for not being a smart man.
While I was there, I checked the cylinder position and noticed that cyl 1 has some slight liquid on it. I believe it's gas, will check in the morning. Is this normal when timing is off a bit or my head gasket replacement did not go very well? Remaining 3 cylinders are dry.

Maybe the intake manifold isn't sealed correctly around the coolant pipe that's in it. That could well be the cause of coolant on the piston. Otherwise the HG isn't sealing correctly.
It's unlikely to be petrol, as that will evaporate off pretty quickly.
