    ive been reading how to replace mine. rear started making noises yesterday. I see the part # for the bearings is 6204-2RS. I been noticing some places have p/n 6204-2RSH or 6204-2RSC3. are those different or the same size? also, anyone know of any local places to get the steel wheel spacers, mine are grooved. I found them from the UK for $50 for all 3.

    Thanks

    The 6204 relates to the bearings physical size (ID, OD and width) the 2rs means 2 rubber seals, and the C3 means a tighter tolerance bearing if I remember correctly.

    C3 is a looser clearance, absolutely essential on alternator. The alternator can easily hit 12,000 RPM, the bearing heats and a C2 will seize. MUST BE C3

    C3 is the standard tolerance.. C2 is tighter tolerance... most bearings are manufactured to C3 tolerance.

    C3 will be fine. These are standard industrial bearings, made for far higher speeds and loads than they ever see in motorcycles.

    Motorcycle wheel bearings fail from improper installation (installed too deep or in the wrong sequence so they're side loaded, or pounding on the inner race) or from water/dirt getting in. They never really actually wear out.

    Make sure you get a real brand. Most are nasty crap. An industrial supply house anywhere in the world will have both. The price difference is not great - usually you will pay less than any retail, especially a car or motorcycle orientated one.

    Just for asking, I usually get 70% discount.

    SKF6204 2RSC3? I don't have to replace them so often now in the blade spindles on my riding mower.Spindles came with cheap Chinese bearings and only good for a year of beating on them cheapos.SKF C3s are good for 2-3 years.

    Must be one of the most common bearing in the world the 6204.

    Spacers? Very important as they set the preload.I'd go OEM unless a machine shop could guarantee replacements are exactly to OEM specs.

    There have been a lot of ebay and amazon knock offs lately. Not genuine OEM stuff.

    Ok need advise. Drive side bearing came out easy. Brake side was the one destroyed, everything came out except the OD part of the bearing housing. There's nothing to grab onto to bang out from other side. Was trying to create a lip with dremel to get some purchase until battery died. Waiting for it to recharge. Any ideas.

    This is what the Breakside one look like when it came out. Notice the bad Groove in the spacer.

    Driven at an angle, 1/2" round stock or a long chipping hammer bit & alternating sides might catch enough to walk it out. The hub is a big enough heat sink and the race is small so hard to get enough temp difference for thermal expansion. Some cans of computer duster if held upside down will spray liquid freon.

    If something was stubborn or big I'd usually stick weld a bead on the inside of the old race, when cool it shrinks it enough to often fall out. Sometimes a slide hammer with a hook works.

    Yeah theres not enough to grab with the rod. May try welding a bead then may give me something to bang on.
