Not safely. Check the how-to section. There’s a couple ways to do it, but if you’re not careful, you’ll break the pulley as well. There are a couple of home-built setups that will do the trick.

I use a Harbor Freight bearing separator and puller. I am not sure why that would be unsafe.
Heat and pull.

Using a 2 or 3 jaw pulley puller may break the pulley.

Clamp the bearing separator behind the pulley on the hub and put the gear puller on the separator. That way no force is on the edges of the pulley where they tend to break.

Those sizes will work on the crank shaft pulley. They will also work for pulling steering wheels.

If you are going to purchase one, buy quality. I picked up one at auction. Purchased an inexpensive bearing separator, broke first attempt to use.

If you have access to a plasma cutter and some thick steel plate, you can make one in a few minutes. If the plans are no longer on this site, PM Ron Baker (MidMo) on this site. He may still have the plans.

Edit. If you purchase a bearing separator, purchase on with 3 different pulley sizes, one with a size smaller than 2". Reason, you will need a smaller size to remove the pulley from generators, starter/generators, electric motors, etc..
I have an excuse. CRS.

I use certainium alloys and research company castiron arc welding rod. Now following the correct way to weld castiron the joint preparation is the key to doing it right. The joint must be beveled so more weld can be applied. Preheat mush be done before welding. After the welding is done it mush be cooled down slowly. The weld will hold up.
I'm technically misunderstood at times i guess its been this way my whole life so why should it change now.
