Ok so Deuy (my brother & guineapig ) needed new rear wheel bearings in his 2009 KTM 300 exc so I go and get bearings, seals & a circlip from local bearing shop.

Has anyone had the bearing on the brake side just slip in??
My thinking this is not right should have to be tapped in softly!!

Does the hub wear over time so this happens and it's time for a new hub?
I think it is!!

The chain side had to be tapped in like I was shown.

This is the first time doing anything like this but it was easy.

2015 KTM 500 EXC-F - just Awesome

I hate it when the voices in my head go silent...
I never know what they are planning.

Yeah you got problem Boze :( you can centre pop the hub and loctite it but it won't hold I have tried that before and long term it isn't a fix IMO I mean it came loose before with a full surface area didnt, again just my thoughts. I have stripped the wheels before and had the worn bearing area in the hub machined out and a steel sleeve inserted to restore the bearing seat area to the original size. The positive is the steel area that the bearing will now sit in wont wear like the soft alloy hub. The other option is a new hub, start soaking the spoke nipples in WD or the likes now

If you need a hub laced sing out, maybe you could source the hub from Suttos and send the wheel down I can pick the hub up, lace it and sent it back. Just a thought (I like building wheels :whistle: )

Boze,

If your concerned that the bearing is too loose you could use some Loctite.

Which Loctite would depend on how much clearance there was. The stronger you go the harder to replace.

I've needed heat to shake the bearings loose on my DRZ and Sam's KTM, you'll probably need heat if you use Loctite too.

Wheels are relatively slow in the revolution stakes less than 1000rpm @ 100kph.

But they do have high loadings so it pays to keep them firm in place.

If they are quite loose you could always do the centre pop trick, haven't had to do it on a bike but it's worked on many other situations :whistle: Not sure how it would go though.

Adam.

You only live once !!

And I came up with that way before the Facebook generation did !!!!

Mmm not my problem TB Duey's problem. Yep thought it was not right but thought I'd throw it out there.

Funny the things you find when you do the job your self..

The one bearing just popped in using my fingers, so im guessing that the whole lot (bearing) is going to spin. So being like a loose fit it will probably smash the hub when it go's.

So a new hub should do it

Thanks

Boze it wont smash the hub just gets more and more movement over time
