Can I fix my hub?

17 posts in this topic

Hey guys the sprocket side wheel bearing started spinning in my hub. I already replaced the hub and put new spokes in wheel. My question is, can I fix this hub? I would really like to reuse this hub so I can have a spare wheel.

I would first try red loctite on it. If it still is a problem, you can have the hub knurled. But at some point, the hub will just not be worth the trouble.

I doubt you will fix it permanently, but I repair Spin Bikes for the local Health club and they have aluminum frames and the bottom brackets come loose and if not detected early the frames wear larger than the pressed in brgs, I have used Permatex Bearing Mount, made by loctite , the Permatex item # 20297, it fills gaps from .005" to .020", resists oil and chemicals, temps to 300 degrees, and drys in 2 hrs. I don't know the loctite # but it should be on their website. I have also used it on my ttr125's rear hubs loose brg and it is holding so far. It's $7.95 for 0.20 oz. Mike

Mike, that's good advice. Bearing Mount is an excellent product, but in this case, I think the first words of your first sentence are at the heart of the matter.

The real trouble is that the bearing pockets on a number of '06 hubs appear to be weaker than others, probably due to a casting defect on that side of the hub, and while Bearing Mount will certainly hold for a time, the question is whether the pocket will then cease to open up with further use.

Well the plan is to build the extra wheel and use it on my 250 2 stroke. I replaced the hub on the 450, if I build the wheel I will only use it on my 2 stroke. Do you think that the hub will hold better on my 250 since it has less power?

Less power and less weight will both work in your favor, but you should keep an eye on it, to be sure. Who knows? It may even hold.

Grayracer, that was my thoughts also, it worked on my TTR125, but my son doesn't jump that any more, just some supermoto on a Gokart track, so not much stress. Mike

Do you think it would be worth it? I don't feel like building a wheel to only use it once. Thats way too much work for nothing.

no i dont think so, spend the extra money and save the headache

Well its not like I am really spending money. I have a 250 2 stroke and 450, I replaced the hub on the 450, I want a extra wheel for the 250 though. I was thinking since I can maybe fix this hub I can build a wheel. If I can't fix the hub then it looks like no extra wheel.

I have used that loctite stuff before at work on transmission bearings within the working spec of the loctite, it works for a while, but if theres enough vibration, it always seems to fail. I wouldn't trust my life on a patch fix like that.
