You don't necessarily have to have a pilot bearing puller to get
the pilot bearing out, I've done several clutch jobs and never used
one. Here's how I did it:

First, I found a deep well socket with an O.D. slightly smaller than the hole
through the pilot bearing. I then filled the inside of the socket with duct tape 
and also wrapped the outside of the socket with duct tape, so that the
socket just fits snugly into the bearing.  I then filled the void in the end
of the crankshaft behind the pilot bearing with some cheap wheel bearing
grease.I placed the socket into the pilot bearing hole and hit the end of
the socket firmly with a hammer until I felt the socket hit the crankshaft.
Each time I hit the socket with the hammer, the hydraulic action of the 
displacement of the thick bearing grease pushed the pilot bearing outward a 
bit.  Once the socket hit the crankshaft, I removed the socket and refilled the 
void behind the pilot bearing. I repeated this process until the pilot
bearing was free.

For all of you that recommended the grease trick to remove the pilot bearing,
I have tried and could not make it work it just got messy. A pilot bearing 
removal tool was hard to find, and the ones I found could not fit into the
toy pilot bearing so here is my fix:
 
I cut an alternator bracket in half and kept the part where the adjustment
bolt (12mm) fits. found a 10 mm bolt put three nuts in it one at top of the bolt
and the other two at the end of the bolt with the alternator bracket in
between. I also cut a small piece of a 10mm bolt to the size of the pilot 
bearing.

Then I inserted my crude pull  remover into the pilot bearing put the small
piece of the 10mm bolt on the side of the long bolt and tight the 10mm nut 
snug against the bearing that will keep the 10mm nut at the end of the long
bolt tight. So with the alternator bracket against the 17mm bolts on the 
flywheel I was ready to start tightening the top ten mm nut and sure it 
worked.

crude picture above shows the order in which the pieces work. Right hand 
side is the side to flywheel.

It would have been easier if I just had the puller.

Followed you this far.  Can you explain the piece of 10MM bolt more?  
How does the puller pull this piece and hence the bearing?  This is 
what I picture from what you described:

        Nut-->_|_
               |
      ________ |____________<-- Bracket
               |
        Nut-->_|_
               |
10MM piece-->| |<--10MM bolt
         ____| |____ <--Bearing face
             | |
      Nut-->_|_

I used a 5/16 craftsman 1/4" drive socket coupled with the 3/8" to 
1/4" adapter (to plug the socket hole), although the socket seemed a 
little loose to work at first inspection. The trick seemed to be to 
really make sure the crank was packed, and the *socket* too.

It took about 5 full seats of the socket to pull it completely out. 
After each full drive in of the socket, the bearing will pull out only 
about 1/16" to 1/8".  Repack the crank and the socket each time.

Only took about 15 minutes after gathering all the parts and prepping 
the crank.

BTW, looks like Daikon clutch kits come with the OEM bearings (Nakki, 
I think).  The disc springs are heavier duty than the Aisin disc I 
pulled, and it is plenty thick.  The pressure plate fingers look 
perhaps 1/64" less thick.

FYI:

Found a pilot bearing puller from Harbor Freight for $9.99 that works on 
12mm (1/2") ID bearings and up.  Think the 22RE pilot has a 14mm ID.  
Beets the $20+ price from Owatanna.
