What tool do I need to remove this crank?
I have this Specialized Allez bike that I'm trying to upgrade the crank for.
Can anyone tell me what tool I need to first remove this crank and second how it is done?

Looks to be a common arm extractor tool. Park CCP- what ever is the current version. So the retaining arm bolt gets removed first with an 8mm hex wrench. Then the extractor is threaded into the now exposed arm threads and used to pull the arm off the spindle. Google bicycle crank arm removal for more details. Andy.

To add to Andrew's post. There are two basic sizes of these tools. The older type made for square taper spindles, and the less old one made for the larger splined spindles (aka Isis, or Octalink).
The tools are basically the same except for the pusher pad diameter which has to match the end of the spindle. Some tools have interchangeable pads and can fit either.
Either buy the tool that fits either, or use an 8mm hex key to remove the bolt on either side to see which type spindle you have.

Thank you both. I will have an 8mm hex key shortly (Park CCW-5), then I can remove the bolt cover to find out what kind of spindle it has. My guess is it will be the spline type (thanks for the photos by the way). If so, is this the tool I should get?

or do I need to know the size first? This is a 2008 Shimano Sora crankset.

OK, the saga continues.
I removed the cover and now I see this:
https://i214.photobucket.com/albums/c...14/crank-1.jpg
As you can see it is a square opening with a thread inside. How do I remove the crank and what tool do I need? The CCP-22/44 were not the right ones.

No saga, the OP should reread the earlier posts, including mine (Nos. 2 & 5) where he was advised on what to do. The CCP-22 is the right tool for the job as are many others.

should fit a "2008 Shimano Sora crankset".
i guess it's possible that the threads are mangled or stripped. have you tried it on both sides?
have you ever used a square tapered crank puller before?
here's a video:
it's usually one of the few things that are pretty much universal. i.e. square tapered spindle, ccp-2(2) puller.

I haven't used a square tapered crank removal. This is my first ever.
Found this vid, which explained it very well.
Remove A Square Tapered Crank - MadeGood | Free bike repair resource
The problem was that the thread on both sides of the crank were either not lubed or had some material debris in there.
I was reticent to use force but I did and the tool went in as explained. Crank came off easily on both sides.
Thanks.

It's not supposed to fit the spindle thread. The outer body screws into the crank arm threads, (surrounding the square hole),all the way to the bottom. Then the inner part is like a screw jack and pushes the spindle out of the crank. It's only important that it's small enough to enter the square hole, otherwuse you';re pushing on the same part the outer body is threaded into.

You are right, the tool is essentially a 'pusher' once the outer thread is in to the extent that it can go (the thread part *outside* the square hole, where the covering screw goes in). The video I posted is the best I've found that explains this process. But thanks for your help. I now know what to do the next time.
Tools aren't magic, and need some knowledge in their use. Had your question implied that you needed A-Z help instead of just a tool, you would have gotten the whole answer in a single pass.

BTW- it can save time and headaches if you ask the right question. Instead of asking "what tool do I use....? Consider asking the whole question "How do I remove...."
Tools aren't magic, and need some knowledge in their use. Had your question implied that you needed A-Z help instead of just a tool, you would have gotten the whole answer in a single pass.
