Anyone know how to remove AT crank bushing?

Ok, my new 2.4 engine is 99% ready to go into my car now, but were just pondering about the Flywheel installation. I have RRM's Flywheel and Clutch.

The problem is that the 4G69 I have was originally an Automatic, so had a AT Drive Plate instead of a Flywheel.

We've removed the drive plate, but need to change the crank bushing from what the shop manual lists as "Crank Bushing <AT>" to "Crank Bushing <MT>" I have all the parts obviously.

What I cant seem to do is get the AT crank bushing out. Here is a pic to help illustrate - I'd imagine it just pulls out, but I cant seem to get it out. Any ideas?

Try this?

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.
Might work better with the socket reversed, and an extension stuck through it into the square hole. Then hit the extension.

Worth a shot I suppose! Thanks. Im sure Mitsubishi have a tool to do this easily... but no mention of removing it in the shop manual.

Put some bearing grease in the bushing so you get a good seal to push out bushing
