Hi There, I bought a Xt660z that has the double bearing mod.
The bearing is now rooted and I want to replace the bearing with the same but having trouble finding it at the bearing shop - just confirming the bearing # NSK SM-G903F ?

Hello Ballylurgan,
Check out the 3 previous pages as there is all of the info that you require, And don't forget to check the 2.5mm lip that double bearings seat against for any cracking that is also mentioned previously.
