  • I show how to take apart the bottom bracket of a bike with a one piece crank, clean everything, install new bearings, lube it and put it back together again. The grease I use is just a good quality automotive type grease. This bike is a GT Bullet 24 inch kids mountain bike. I got it for free, but it was very dirty and rusty. I was concerned water had gotten into the bottom bracket. But everything actually looked pretty good.

    Thanks RJ. I've learned how to repack wheel bearings, coaster brakes, headset, and cranks from your videos. I've saved bikes from the garbage, fixed then up and donated to charities.

    Very helpful! I've not done this in forty years, so I thought I'd better watch someone do it!

    Bearings are made to very exacting tolerances. So they may be worn and you couldn't tell by looking at them. They are pretty cheap though. You can replace the the bearings for just a few bucks. But can you just clean them up and reuse them? Sure. I have done that before too. As long as the cranks turn smoothly and you aren't feeling the bearings as you turn the cranks.

    I'm sorry I missed where you said I had to use the axle grease from WWII. It took me the same amount of time because I kept doing it wrong and had to redo it and wipe everything three times.

    If you put grease on your palm and tap the bearing on the grease as you turn the bearing it's a better way to pack bearing.

    Thanks 🙏 RJ ...... it seems to me that if one does not look after theses bearings the inner races get ruined as well ....

    Do you always want to replace the bearings? Or can you clean and repack the existing ones?

    So, it is one-eighth inch each bearing is measured (on a freewheel like Shimano MF-TZ21).

    Do you always replace the bearings? Why not just clean them if they are O.K?

    If I want, I can just put neither marine grease nor waterproof grease on my Shimano 7-speed (MF-TZ21) freewheel. Marine grease is my best grease of choice. Do you think so, shyflirt1? I may as well put enough marine grease on the bearings. Actually, my freewheel does have issues of its own. So does my bottom bracket. (I own a Mongoose mountain bike.)

    • @RJTheBikeGuy
      @RJTheBikeGuy  10 років тому

      !/8" bearings are pretty standard in freewheels. I prefer marine grease. If you are taking the freewheel apart, you kind of need the grease to hold the bearings in place. My freewheel video is more of an FYI. If the freewheel is worn, it is generally easier to replace it. You can clean and lube a freewheel..I have a video for that,, andf I recommend Phil Tenacious Oil.

    • @madisonjoyce5964
      @madisonjoyce5964 10 років тому

      1/8" bearings...Got it. You can grease the pawls, not just putting grease on the bearings.

    Hi there, I was wondering what size cone wrench you used on the bottom bracket lock nut? Thanks!

    • @RJTheBikeGuy
      @RJTheBikeGuy  9 років тому

      PARABOLOUS Either a 32mm or a 36mm. Not sure. But I could have just as easily used a big adjustable wrench.

  • @torkaman

    is there a way to upgrade the bearings to maybe a press fit bb? I am trying to use my old shimano triple road bike cranks to a bike with a one piece crank

    • @RJTheBikeGuy
      @RJTheBikeGuy  8 років тому

      +torkaman You need to use an adapter: ua-cam.com/video/7xTJ4ZmWmU8/v-deo.html

    How do I find a replacement for the keyed washer on the non-drive side?

  • @nickhall1376
    @nickhall1376 7 років тому

    would this procedure be the same for a bike that has the pedal brakes?

    • @RJTheBikeGuy
      @RJTheBikeGuy  7 років тому +1

      If it has a one piece crank, then probably yes.

    • @nickhall1376
      @nickhall1376 7 років тому

      RJ The Bike Guy ok awesome. where do you order replacement bearings from?

    • @RJTheBikeGuy
      @RJTheBikeGuy  7 років тому +1

      I get them at my local bike shop so they can match them.

    • @nickhall1376

      RJ The Bike Guy ok I'm sure we have one around where I'm at. thanks for the help.

    What is that wrench with the yellow handle called?

    • @RJTheBikeGuy
      @RJTheBikeGuy  5 років тому

      A cone wrench. But a big adjustable wrench would work as well or better.

  • @shanevieira823

    So my bike is not a mountain bike and I need to do this, is it the same?

  • @Dogsparkster
    @Dogsparkster 8 років тому

    on now i see after watching this video when their is grinding it is normally because there isn't enough grease put grease on and i should be find no more grinding

    • @RJTheBikeGuy
      @RJTheBikeGuy  8 років тому

      Not enough grease, worn bearings, bearings clamped down too tightly can all cause that.

    • @Dogsparkster
      @Dogsparkster 8 років тому

      so I don't even need new bearings probably it could be lack of grease

    • @Dogsparkster
      @Dogsparkster 8 років тому

      so the hyper bike i have it says on amazon standard 3 piece high performance crank so will this work on it it is a hyper summit www.amazon.com/gp/aw/d/B001VS1M20/ref=sxts1?ie=UTF8&qid=1473747520&sr=1&pi=AC_SX236_SY340_FMwebp_QL65

    • @RJTheBikeGuy
      @RJTheBikeGuy  8 років тому

      If it has square tape cranks, then yes.

    • @Dogsparkster
      @Dogsparkster 8 років тому
