These are the SKF part numbers for the XT660Z - they may or may not be the same for the other XTs, but it will help any Tenere owners reading this I imagine...

Ok,I would like to wake up this post because I once sayed that I will change my wheel bearings.
That time came two weeks ago and I faced a problem...


How am I going to get the rear wheel's bearings of the hub???


There is a spacer between the two bearings that prevents a common bearing extractor to pull them out...
I must take them out in order to measure them...(although I had a chance to measure them but I want to be sure before I announce any dimensions)
Any suggestions?(the same thing must go for the front wheel I believe)

I would pop the seals out and then tap out the wheel bearing using the tool in the attachment. (Second attachment is just for illustration purposes)

My friend Tony,there is no room (from the inner side of the bearing) for that tool to push the bearing because of the spacer.
Unless I am thinking a wrong way.

As an aside,before you install the wheel bearings pick off the seal and put in some more wheel bearing grease. I usually use a small fine screw driver and take the seal off at the centre.The bearings usually come with a minimum of grease in them. Press the seal back on and you're good to go. Before you put them in,put them in the freezer for about 20 mins and before you install them pour boiling water from the kettle onto the hub...this'll expand same meaning they'll either drop in nicely or just need slightly tapped in(using a socket as a drift...the same size as the exterior diameter)


The dust seals can be found usually,if you take one in to a large farm supplies place. My last ones were �3.50 each. I usually put grease in these too.
