Warning: Fractured Wheel Bearing
Several days ago I replaced the Shinko 244 tire on my rear wheel. I always inspect every part of the wheel every time I remove a wheel, or replace a tire. The rear hub has two bearings, and the bearing near the rear sprocket was completely fractured. I needed to cut the outer race of the fractured bearing with my dremel tool in order to remove it from the hub.
The bearing on the other side, near the brake rotor, was notchy, and ready to fail. I replaced both Chinese bearings with Japanese bearings, which I had in stock for the original hub of my Zongshen ZS200GY-2. The bearing in the sprocket carrier was in good condition. The stock bearings have very little grease in them. I packed the new Japanese bearings with extra grease before I installed them. I have ridden over 13,000 miles on my RX3. However, I encourage everyone to check the wheel bearings, no matter how low your mileage. It is much easier to punch out a wheel bearing before it fractures. I will post photographs of both Chinese bearings tomorrow.

If you replace a worn bearing before it fractures, you can easily remove it. I prefer to drive out wheel bearings using a Motion Pro bearing driver and split collet. The bearings in the rear wheel of the RX3 can be removed using the following parts.
http://www.motionpro.com/motorcycle/partno/08-0260/ http://www.motionpro.com/motorcycle/partno/08-0268/ Just in case someone hasn't used this method to remove wheel bearings, here's how it works.

I have bought individual drivers and split collets for the different sizes of wheel bearings in all my motorcycles. However, if I were buying the bearing drivers today, I would get the Pit Posse Motorcycle Wheel Bearing Remover Kit, PP-1692.

You can decipher the bearing code by reading the information at the following links.
http://www.gizmology.net/bearings.htm http://www.mymachineinfo.com/2015/07...ion-guide.html http://www.engineerstudent.co.uk/bea...explained.html http://www.engineerstudent.co.uk/bea...plained_2.html For example, a 6202 2RS bearing has the following features. 6 = Deep Groove Ball Bearing (Single row) 2 = Light Duty Bearing 02 = Inner Race Diameter of 15 mm 2RS = 2 Rubber Seals

Wheel bearings fail more quickly when they lack sufficient grease, and every wheel bearing I have examined suffers from this deficit. For example, here is a new wheel bearing I was going to install in one of my Honda motorcycles.
Therefore, I always pry off both rubber seals, and add more grease to the wheel bearing before I install it.

Using a bearing driver makes it much easier to remove old bearings.
Just make sure you get the correct size driver and collet for the bearings you wish to remove.

Lee, I do also, my bearings have 16K km on them and they're smooth as silk, but as you said it's cheap insurance to change them anyway.

Is this info on the sticky thread about parts? I was about to ask about front bearings also.

Anchor Bolts and a slide hammer (or a anchor bolt, hammer, and punch combo) can also be used to remove Old Wheel Bearings and they only cost about $1 or so for the size of bearings our bikes use
