Bearing removal on sealed OPC BB? PICS ADDED

(1/3) > >>

Gary72:
Trying to strip down a frame I got today and it has a sealed BB on a OPC.  How do I get the bearing out on the non-drive side? I can use the crank to part push out the drive side bearing not all the way out though.
Is there a speacial tool, Dont fancy taking the grinder to the crank as I think it is a Sugino.
Help needed

i've always used the tip of a flat screwdriver and gently tapped out the bearing and cup in one go.

Gary72:
There is no cup, Think I might need to get some pics.

Wife is out working and taken camera with her. But got bearings out, Managed to get the drive side out completly, Then got non-drive side started. Bearing have a small lip all the way round. Had to put drive side back in abit.
Now run into another problem the threads on the drive side of the crank have worn and cant get the spider nut off. What size is the thread on the crank? Should be able to get a die and re-cut it enough.
Also one of the bearing is a rusty mess so dont think the BB is re-useable :buck2:
