how can i remove a torn up clutch pilot bearing?

there are tools for removing pilot bearings. you can rent them at a parts store.

as i asked, is it roller or solid. it makes a difference

the pilot bearing is a roller bearing.

What i do is make a pulley by getting a large bolt and grinding the shank back so it makes a hook end, weld this to a rod with a slide weight and an end stopper (basically a slide hammer) hook end over bearing and then lock in place with a suitable size pin punch knock this in so the hook and punch are locked into the bearing race, and it then should knock out using the slide weight, works every time.
