    Hi Folks,

    Bonus points for the seals.. hehehehe

    Regards,
    Mane

    The numbers are on the side of the bearings.
    All the different manufacturers will use the same numbers (hopefully)

    Also double check the.bearings on your cush drive. As for some reason there were different sizes between the.years.

    The sprocket carrier bearing is different, old style is 3206 (expensive) new style is 6006 x 2.
    Front dust seal 35x47x7
    Rear dust seal 30x52x7

    Good point! I edited my reply cos I made a typo in one of the numbers. All the wheel bearings should probably be of the 2RS variety (ie 2 rubber seals) although I've used 2Z (2 metal shields) in the past when only those were available.

    When you say old style do you mean 950?

    While replacing the wheel bearings do you guys also replace the spacers?

    I'm thinking about leaving the old ones (since KTM don't sell separatly). What do you guys think?

    Unless something has caused damage to the spacers there really isn't any reason to replace them.

    Have yet to change a wheel bearing that I have installed myself.

    If cleaning and replacing seals and spacers and every now and then popping of the seal on the bearing to add some grease they should last a very long time.

    If replacing them I use a rotary tool to notch the spacer between bearings so it's easier to get them out the next time should that day ever come.

    And as far as spacers go I'm quite sure they can be bought separately. Know I have replaced mine once the groove in them got a bit big, they are just aluminum.

    Hmmm, which spacers? Outer spacers or the internal?

    I was talking about the inner spacer.

    I think Dirty is talking about the outer spacers.

    Inner spacer tube between bearings can be bought separately also.

    But if replacing everything the KTM kit used to be a good price at least. Was a few years since I compared prices with both buying separate parts or aftermarket.

    Probably, but I'm not sure exactly when they changed. The definitive way to find out which you've got is to see if there are two bearings in your sprocket carrier, I suppose.

    Hi, for example the front bearing is more than just 6906 RS. It`6906 DDU2CG23S6NM - where the CG23 means that the inner diameter is reduced by 23 hundrets of mm to ease the axle removal/refitting. If one puts ordinary 6906 bearing in place, hammering the axle out/in is possibly foreseen. Same applies to rear wheel.
