Bicycle hub sealed bearing upgrade for under $1 plus parts

In this video I attempt to upgrade an alloy Shimano Mountain Bike hub to a sealed bearing for under $1, without using a lathe or any fancy tools except for a drill (or an impact driver) and a 3D printer... if you don't own or have access to a 3D printer you could always make the tool out of wood if you are a bit handy.
When I was a teenager I did some awesome modifications to bicycles, but long are the days where I could go into a hardware store or bike shop and just buy a bearing race, these days its individual ball bearings of many different sizes. Now, sealed bearings are something I can get behind.

Also available longer solid shaft versions: s.click.aliexp...
And the 60002RS (rubber seal) or 6000ZZ (metal seal) 10x26x8mm bearings: s.click.aliexp...
Digital calipers I really need to invest in: s.click.aliexp...

Note: The bearings I used are 60002RS 10x26x8, so its 26mm, not the 25mm I mentioned in the video, we can thank the inaccuracy of my steel rule. I verified this by checking from zero, and then again at the 10cm mark. Fortunately it all turned out just fine with my 24.5mm design which came out of the printer a fraction over 25mm anyway. I need to do my eyes a favour and invest in some digital calipers like these: s.click.aliexpress.com/e/_DC2wp4r

Strange, it works on my end, even in a private window. It's a digital caliper.@@patrickbodine1300

Use wide washer to evenly torque in the bearing

[@SaintThomas2009]

Sweet upgrade! I bet the wheel rolls super smooth!

[@FixTechStuff]

It does indeed. After finding the bike shop didn’t even stock bicycle bearing races (they only had balls), I think, if possible I would change everything over in future. So much easier to work with and replace too.

[@1OTDM]

The Bike Sauce built a pretty simple little bearing press which seems easy enough to use to do this. The video was called "Replace Sealed Cartridge Hub Bearings" or something similar.

I have an ancient (80s/90s bicycle) with a busted old type (non-sealed-cassette) BB. However attempting to stuff a new sealed bb in the shell I learned eventually that the shell is tapped for an Italian threaded BB/end cups so I've probably buggered the aluminium threads. The whole thing has been so much more of a nightmare than the last one I did, many many many tools for this mongrel/money pit of a bike, square wrench flats, hammer, washer, whole toolkits, working all night until I had to leave for work attempting to beat train strikes etc. FML, the things in pieces as I can't find the correct threaded cassette BB anywhere to put it back together. All in all your video made me happy just bcos it shows I'm not the only one having to get extreme to fix these b*sterd bicycles. I'm thinking my next step is to rebuild the existing BB as I have new bb's and races ( I hope they will fit the old spindle!) Or to buy a stripped shell BB that has external bearings iirc! Thanks anyway!

It's good to know we are not alone! With your nightmarish situation, it might be worth checking out your local recycling centre / tip shop for other bikes or parts. I often mix and match bits and pieces to get results. I've collected enough that I've passed up on some really nice bikes because they were barely much of an upgrade from what I've already built. On my wifes 24" bicycle I swapped out the 6 speed ratchet type hub for a newer shimano hub with 8 speed cassette from a spare 26" rim I had lying around. A bit of fiddling about getting it to run true, but really rewarding experience, upgrading something for less than $5 or $10.

@@FixTechStuff tempting, but I don't think my partner would approve if i brought more bikes home haha. BTW, do you think ADHD gives us extra perseverance through hyperfocus? It's a blessing AND a curse to me!

Saan ka bumili ng spacer ng axle ng hub?

[@FixTechStuff]

Not sure exactly what you mean, but the links to the axle and bearings I ordered are in the description.

[@paulogracaribeiro2931]

wich filament did you use??? not a 100% sure on the plastic stuff better turning some wood or some rubber!!!

[@FixTechStuff]

I use PETG, PLA will also work, it doesn’t get hot enough to matter. If you had a lathe obviously wood would be better.

[@pauloribeiro1627]

If you use a hole saw and cut the wood at the right dimension.

[@FixTechStuff]

that might work too@@pauloribeiro1627

Trying to find bearing cups on aliexpress, anyone know the search terms?

[@FixTechStuff]

I looked and couldn’t find anything. I found them on eBay. Another term is “race”, the opposite part is called a cone.

[@jenickjohnson4361]

Can you please suggest me a method to fix a bearing if the bearing seating required few millimetres material more?

[@FixTechStuff]

You're saying the bearing hole is too big for the bearing? perhaps a different size of bearing is available, I'm not sure

[@jenickjohnson4361]

@@FixTechStuff the problem is with the axle. I am thinking to fix it by rolling some paper or plastic material around the axle.

[@FixTechStuff]

Aluminium can as a shim might be a good option, other than that buying an axle from aliexpress.@@jenickjohnson4361

[@jenickjohnson4361]

@@FixTechStuff I tried that but when I try to stuff it, it deforms. I have to try it again.

[@willjenkins2842]

grease that puppy up! =)

[@FixTechStuff]

Yeah for sure, the grease in those bearings looks like vaseline and we can do better than that.

This a fake video 1 my A do you know how much a 3d printer would coast just to to do this?

[@FixTechStuff]

In the description I wrote: "if you don't own or have access to a 3D printer you could always make the tool out of wood if you are a bit handy." You could get a piece of broom handle, drill a hole and sand it to size with a drill or something. See if your local library or some other organisation has a 3D printer. My $149 3D printer has more than paid itself off with all of the useful things I've repaired or made, so it was money well spent.

[@peterxyz3541]

The 3d printer does cost (at least $99 new, with promotion price at microcenter); but, missing the point of this vid: Less money = more brain Or the internet meme: Girl’s voice: “How are you so good in so many things” Guy’s voice, sound of frustration, sound of exhaustion, a bit of prideful flex: “when you’re poor, you learn how to do many things” Or…the point of this vid: Outthink your problems. If I done have a 3d printer (I don’t), I would use a drill attachment (cheap at harborfreight) for sanding. What if it’s the wrong size? Another opportunity for you..me to flex and either roll up extra tape or sand paper to size or spin the attachment against sand paper to reduce the size. “How are you so good with so many things”. “Poverty, baby! Either grow or starve😂”
