I was trying to replace the bearings in my Superlight frame and despite buying the specific tool from Santa Cruz to do it, instead of knocking the bearings out they collapsed and I've now got the outer races stuck in the frame.
Any suggestion for getting the races out, the tool is no use as the flanges on it are too small to catch the outer race - which was probably why the bearing collapsed in the first place.
Thoughts so far are use a Dremel to cut the bearing race, but this seems a bit risky or try and just bang it out with a screwdriver and hammer
Or give up and take it to the LBS
Depends on the size - sometimes screwing a tap into it and then drifting it out from the other side works. Or you can get blind bearing pullers.
Depending on how much of the race you can see, expanding bolt fixings sometimes work. However, I've had to resort to the diamond tip tool in the dremmel before. It's not that risky if you take your time.
Too big for a tap diameter of the outer race is about an inch - its a 7902 bearing if that means anything to you.
a blind bearing puller would probably work, but loathe as I am to give up I think it would be cheaper to just take it to the LBS than buy more tools!
If you're thinking about a screwdriver and hammer, I reckon you've got less chance of damage by using a dremel or similar.
I've had to do it on 2 different frames now, take it slowly and you should be able to cut through it without touching the frame.
Just an idea - if you are using a dremel then you could try a circular sanding bit and sand the inside of the race until it is paper thin before snapping it with pliers or something.. this way the dremel won't have any chance of toucing the frame.
Blind bearing puller, why risk cutting a decent frame. If your lbs hasn't got one, try a motorbike shop, it's commonly used for pulling bearings out of wheels.
I used a dremel on a single pivot bike with large bearings. It worked but it needed two slots, and I did nick the frame slightly.
You might have small bearings though which could be an issue. If there's enough of a lip you could find (or make by turning in a drill) two repair washers of the exact size, screwing them onto a long enoug bolt and whacking them.
Also warming up the frame helps, because alu expands more than steel.
