If you used a puller on it, the pulley is now dead, due to broken adhere on the rubber insert, so cut it off. May have the same problem with the timing belt sprocket, but they are powdered metal and can be drilled and split off.

PB Blaster is a very good penetrant, as is Mouse Milk. Try some sharp blows to the pulley near the center...


Not sure what you mean about "dead", the pulley isn't deformed and hasn't moved...it's still stuck to the TB sprocket as far as I can tell. I'm not cutting anything off right now but thanks for another "short-cut".

I'm looking for some ideas as to something I may be missing in the removal process or is this common for it to stick like this?
