I recently upgraded to greased carbontex an old Abu 6501 c3, this reel was having problems with the IAR bearing, and when completely locking down the drag to test it and pulling line out of the reel, the IAR slipped and broke. Some time ago I ordered a new IAR from mike's, so I decided to install it.
Use impact sockets, a 9mm that fits the IAR, and a 14mm to fit the handle side plate.
See that the 9mm socket fits nicely inside the 14mm
Used the c4 only for demonstration purposes.
Be sure to center the 14mm socket correcty, if not, you WILL damage the side plate beyond repair when using the press!!!
This is how you will put the pieces once using the press
Broken and old IAR
Apply some oil to the inner part of the side plate, to help the new bearing slide in.
New IAR bearing
For pre-installing the IAR use a towel to avoid scratching it.
Notice the 14mm socket is centered
Once you can't keep on pushing the IAR only with the press, use the 9mm socket.
Remember that the IAR-B has to be correctly positioned, if you push it in too much it WON'T work, and also if you don't press it enough the same will occur, so push slowly and check often. If you pressed it in too much, keep on pushing until it comes out and try again, don't try to push it the other way around, you will damage the plate!
