    Default Bearing Maintenance

    I had a discussion recently with a customer who was under the impression bearing maintenance wasn't possible with the types of bearings these cars use. This is a misconception many have as well many simply don't think bearing maintenance is important.

    Maintaining your bearings can save money and down time.
    Wheel bearings get extremely dirty inside and clutch bearings get very hot..

    There are different ways of going about cleaning bearings,
    1. Buy a bearing re-greaser that forces in new grease while pushing out the old without removing seals, although this does a good job I am not convinced it removes all dirt and contaminants not to mention uses a lot of grease.
    2. Using an exacto knife carefully remove the seal (usually the seal that won't be exposed to the elements) Spray the bearing out with bearing cleaner, nitro cleaner or some sort of alcohol based cleaner that will evaporate. Then add a light grease you can get at a hobby store or automotive shop.
    There are claims there are greases out there that are formulated for RC Cars, again this is something I am not overly convinced about based on the cost of development alone.

    Once the bearing is greased reinstall seal.

    Seals are a metal coated rubber so don't be too rough taking them out, it is easier to pop them from the inner race side.

    Cheers,

    Good call.

    And just to add don't over pack the bearing with grease, about half full is what your aiming for as excessive amounts will only get pushed out and if its an area like the clutch will likely end up getting all over your clutch bell. I'm also not a fan of those bearing greasers that force grease in as they always over pack the bearings.

    rhino, When a pinion is tightened up against the bearing it creates side load. The spacer takes the side load off of the centre bearing race especially when it is shimmed regardless of the material the carrier is made from. It helps the pinion to be shimmed correctly without creating rotational resistance.
    The only time it isn't needed is when using our VPP1652 Hex drive, the pinion tightens against the shoulder of the shaft, not the bearing.

    Ceramics have the same rubber seal and get just as dirty.

    Becareful with brake clean, it can harm some plastics.
    We have non-chlorinated brake clean here in Canada, much safer for plastics.

    Another option is an ultrasonic cleaner filled with isopropyl alcohol (99.9%) rubbing alcohol or denatured alcohol.

    The biggest issues with one-ways on smaller models is oil from the engine seeps into them.
    Spray one ways with alcohol based cleaners.

    On the larger models spray out with cleaner then "very lightly" grease.

    the bearings that came with my new hubs were very raspy and I was going to bin them but I stripped them and cleaned them and they are like new now ..





    I oiled them instead of greasing them cause they are so easy to take out and do again ..
