Any other bearing removal techniques?

[Studio42]

There's been two recent people complaining of bearing being stuck and destroying bearings. And these are from what i take to be fairly new yoyos.

Now, correct me if I'm wrong here. As I understand it correctly, the anodizing process actually adds a tiny bit thickness. If the bearing seat is so tight in the first place, then it's only going to get worse through anodizing. We're talking very small tolerances and I'm not sure it's entirely feasible to measure every single bearing seat. We're talking thousandths of an inch here? Smaller? Chances are these are smaller values than the machines can be adjusted to.

In assembly, I'm sure there's a small group of people snapping in bearings, screwing in axles and tightening halves together. I'm wondering how possible or practical it would be to add a "bearing check" process after the yoyo has been fully assembled to ensure the axle is fine and the bearing CAN come out with "reasonable effort". I don't know how beneficial this would be to YYF as a whole. It just seems like a "freak" thing happens, which in machining can be chalked up to "stuff happens". Since bearings are precision devices, and really, so are most yoyos these days, if one or both are out of spec a little bit, I guess that's where the problems come up. There has to be tolerances with both elements, which no doubt doesn't help much when things aren't coming together properly, or rather coming back apart.

I bet YYF may be taking such "stuck bearing returns" and then filing down the offending areas a little bit, testing it and then maybe selling it as a B-grade.

I believe anodize is about 2 thousandths of an inch which is roughly twice the tolerances of a yoyo (I believe).

Finally got the bearing off. I brought it into the store i bought it from and asked if they had any ideas or had seen anything like this before, and they had once before and had to bust the bearing to get it off. The guy there has been yo yo'ing for a number of years so he knew what he was doing and it took him about 20 min for him to get it off. He started out gently rocking it back and forth and that went no where real fast and eventually just started wrenching on it and then it finally came off. Not sure if the bearing is salvageable or not ill find out tomorrow. I'm thinking of lightly sanding down the bearing seat if yyf wont do anything abut it

Send an email to the place of purchase NOW and if it's within their return/exchange period, then see what they can or will do.

If you want to save time, contact YYF as well and see what they are willing to do.

I just did some bearing stuff myself. MyRecRev Sharp didn't like the bearing in it, so I swapped that Terrapin X bearing for a different one. Love!

Tried the swapped out Terrapin X bearing in my Speeder 2... not so happy. Opened it up, it had some crap in there. No doubt it was bits of dried silicone from  not properly and completely cleaning out the RecRev Sharp after siliconing it(I had it modified to accept flowable). Bearing all better now. A bit loud, but working otherwise flawlessly. I put back in the YYJ Speed bearing in my Speeder 2. Since I was in a maintenance mood, I popped a new string on there and cut it to size. Not sure if I'm liking properly sized strings, but I'll ride it out.

The bearings came in and out of my Speeder 2 no problem. The bearing came out of my Sharp with help from the YYF Multi-Tool.

But, if nobody will do anything about it, I agree, lightly sand down the bearing seat. Just, be super carefull and wear safety goggles.

I emailed yyf last week and still havent heard back from them, the place i bought it from gave me a free bearing for my trouble so i was fine with that. I had a bunch of left over sand paper from a previous project so i took some 800 grit and lightly sanded and its perfect now. Still a pretty tight seat but i can now remove it with a pliers

[Studio42]

YYF's are tight, as has been said. As long as it's manageable, that's all that matters.

I haven't had to contact YYF for anything. But I hear from others the customer service is good. At any rate, it's too late for that route now.

[Dyepb_16]

yeah im not to concerned about it. All i care is that it now works like it should have before lol

[YoyojamFan21]

I have tried using WD-40 and spray like maybe a few drops where the bearing is stuck and try to patiently wiggle the bearing out

Be patient. Don't be afraid to wiggle a little bit harder. Keep in mind, if you're using a drill bit, they are meant to be strong in the plane they are meant to be used in(front to back). If you're giving pressure sideways, they can and WILL break. If you're using a bearing puller, you're fine, you can try wiggling back and forth a bit harder. Change positions a little bit, you never know where the "sweet spot" will be.

Just be patient.

i put some lube in it for mine after freezing it and it went to the bottem and around the yoyo and kind of lossened it up then used the pliers keep up the good work youll get it this means that you are just really good
