Straightening pushed in alloy skyway hub/rebuilding suntour coaster brake

(1/6) > >>

Hi guys,

Well the list of things to fix is growing! I've recently acquired a nice set of Tuff 2's, however the front alloy hub is ever so slightly pushed in on one side, from overtightening the bearing cups.

I've read threads about fixing these, however have not found a definitive answer/method to fix them. Can anyone help?

Here's the hub in question:



I have also dismantled the rear suntour coaster, as it was
Stiff and full of crap, and have discovered that the bearing cup on the 'arm' side is heavily pitted. The wheel won't run smooth like this, so am just wondering what my options are to fix it? Replacements are hard to come
By from what I've seen...



Any advice/links to threads etc appreciated!

Cheers.:)

   Front hub - Unfortunately you are going to have to drill out the rivets and remove the hub. You can then either straighten the flange and replace with some bolts, or use a Skyway hub replacement kit, which pop up from time to time on eBay, here, Museum etc. I have a replacement kit on my rear Tuff and its fine. I wouldnt try pulling the flange out though.

  Rear hub - You could find an old cracked/beaten tuff and remove the coaster parts  or replace it with an Un-Brake type conversion kit.  Sorry I dont know too much about these so maybe someone else can chime in.....

   If all else fails chuck them in the fridge - Historic BMX rumors show that this not only straightens Tuffs out but also de-pits bearing surfaces and pulls out hubs.........apparently  ::)

  Good luck fella.

I think there's a thread somewhere on here about pulling out bent flanges  :daumenhoch:

i made a tool up to pull out crushed hubs so they can be done without removing hubs :daumenhoch:
