These do wear out as the stock bearings are pretty cheap.
Now you don't need a pretty bearing puller and pricy bearing press. All you need is a threaded rod, spares and nut , basic tools like a wrench hammer and punch.
Note I'm using an impact .. because I have one and want to do it quickly, but you needs plier, wrench or ratchet.
washers needs to be between 34 and 36mm or 1-3/8" . For the threaded rod I've use a 1/2" with nuts. You can get away with a just hammer and a socket that is between 34-36mm OD (but you can mess it up so I prefer the threaded rod technique.
The bearings are basic NSK 6202 so I replaced it with 6202 2ZR C3 high quality FAG german bearing, about 5$ each , you need 2. (thanks to Joel for the find)
First remove the motor seal , you will need to wedge a screwdriver inside and pop it out . If it's stuck you can heat it up, just watch the video down below at the 56sec mark.
You will simply have to tap out the first bearing with a long punch, tap the inner bearing sleeve with the punch and tap it all around the ring. Do not hammer just a one spot, you want the bearing to pop out evenly. I didn't need to heat up the hub, the bearing it was not pressed in that hard. If yours is stuck watch the video down below it might help you.
flip the wheel and do it again,
install one bearing at a time if you can, I had a very big socket (bigger than the bearing hole) so I didn't need to buy other spacers. you could press both bearings at the same time , but you have to make sure that the go in square! I've added a tiny amount of grease on the hub so the bearing would slide in smoothly.
Here is a video found on the internet about a street motorcycle.. it's pretty much the same on your Sur-Ron.
