The bearing is a 6200 type, which is 10mm I.D. x 30mm O.D. x 9mm Width.

That doesn't give much room to work, but I wonder if you can use a dremel tool with a cutting disk to very carefully make cuts into the race and to allow breaking it apart.

Either that or a bearing puller attachment with slide hammer that can expand to grip the inner race portion and pull the bearing.

You shouldn't have to cut all the way through the race. Only enough to weaken it. Bearing steel is hard, but brittle.
Be very careful not to cut too deep and into the case. Then the game's over.
You may be able to make a pie segment cut and be able to tap on the outer edge with a punch and hammer to shatter the race.

Earlier this year I had a leaking water pump seal, so had to try and remove the bearing too, using a press. I ended up cracking the outer case as it bent from pressure applied. Really difficult to get the assembly into pieces without specialist tools specific to the job, I think.

So I ordered a new assembly, but didn't realise from my parts book the SP1 & SP2 had different coloured outer covers. No biggie, works just fine.

Getting the outer race using a dremmel would have been a possible but probably a very time consuming solution. Best to just get the assembly and be done with the lost time, I think... In any case, I kept the parts I'd bought so if the same problem occurs again, I could have a solution in case of non availability of parts in future...

i got lucky the shop hooked me up , i think keeping fresh antifreeze in it will help , and i here that blue ice is very bad for the seals , so only water-wetter from now on , on the track instead of just water ,

I replaced the bearing and oil/mechanical seal not to long ago on my SP1.The pump shaft pressed out no problem, but I removed the bearing with a very small puller rather than pressing it out on the inner race.

i think that would have been the best way , i replaced the bearing and oil/mechanical seal every o-ring +++ everything that i could put new i did ,

So sounds like you're all put back together, right? Ready to roll. Did you ride your RC51 on sunday or a different bike?
Good job, glad the shop made good for you. Who was it?
