I need to pull this gear off to take my supercharger apart. Not a lot of space there to grab onto. Is there such thing as tiny gear puller?
It's pressed on, how do I get it off.

I know I will be criticized for this, but here's how I'd do it.
First of all, heat the gear (only), it could be assembled with a red thread sealer, so heat is imperative. It also appears to be a heat fit item, so yeah.
Then I would use a small screwdriver or fine chisel to work under the edge, against that base. Work slowly and on different edges, turning as you go until you work the gear up off the shaft. Maybe you wont need to pry it up all the way, just enough to get a gear puller under the edge of the gear.

I'm not sure about the heat.
The center for the shaft is threaded and I was able to get a bolt in there but it won't do any good I need to push not pull
 
Is there any clearance between the bottom of the gear and the housing? It doesn't look like much in the photo.
If there isn't any clearance you may need to crack it to get it off.
If there is clearance an old fashioned pitman arm puller may work.

You need to push what? I thought you wanted to pull the gear off?

Why not show us some more pictures of the thing? Maybe that shaft comes out with the gear still on it from the side you showed us?

More pictures please.

This is what I would've done. Heat, pry, turn, pry, turn, pry, turn, etc. Reheat, pry, turn, pry, turn, etc.

It'll walk off. Just have to feel the limits of the prying effort.
