Sloppy hub bearing hole
« on: October 10, 2014, 10:40:41 pm »
I have a hub and the bearing hole is not tight on the bearing anymore.

I was thinking loctite or centre punch the hub.

Is there any other methods you guys have for this problem??
I am interested in you ideas ;D

you can machine the hole bigger and have a steel insert/sleeve pressed in.

if the hole is not egged out too much you can use steel shim or an old feeler gauge to take up the slack. put the shim in most of the way then work the bearing in ;) could be used in conjuction with lock tight as well

See if you can get a bearing thats 1mm bigger OD
You maybe able to use a thing called a speedy sleeve available at bearing shops. You can buy some shim steel but thats not a real long term solution. Locktite is only good for up to 15 thou. I would not center punch it.

I've used Devcon's Aluminium Putty as a filler with some success. You could give any epoxy resin a go - just make sure its gone off before you load up the bearing and don't use so much that you glue up the bearing!

good welder and machine shop   bore out bigger then weld up and machine back to size  if the hub is magnesium a bit trickier for some if you can get a good second hand hub for around  $100 go that way   or slightly bigger bearing if enough meat in bearing housing to machine out            cheap way  sleeve will work as well but press fit then machine to size

Speedy sleeves are for worn shafts not for worn bearings recesses, the product for that purpose is called a tolerance ring which you bore the damaged housing out to fit, it has flat serrations on it that get flattened out by the bearing when you fit it & these help it to grip better
