I just did mine in my 01MM700 and let me tell you it was not fun..That collared bearing was very seized on the shaft. I did everything I could think of. I ended up pulling the whole shaft and using a bearing puller. Look around for a replacement bearing. They are very common. 6205 seris bearing. Just make sure it is the sealed collared one. I did both shaft bearings chaincase and speedo side, as well as the oil seal in the chain case for $30.00 cdn. If you have it out, I think it might be worth your while to do both. Just my $.02.
