Afternoon guys,

 

Replacing my rear wheel bearings, all was going fine until it comes to torquing the rear hub castle nut back on.

 

Using the recommended settings, it seems that I can't torque the hub not whatsoever. 

 

It goes completely tight and the hub can't move, and I still don't get the satisfying click.

 

Checked my torque wrench and its functioning properly.

 

Anyone any ideas?

 

Thanks

aftermarket bearing?

[iakona]

Sorry should have specified. Yes its the tapered type.

 

Here's what I've purchased.

Which side rear bearing?? as one side is a reverse thread. i found that when trying to torque up a reverse thread my old torque wrench didnt  register is so i managed to strip the threads.

Sounds like the bearings inmers are binding to the outers. From the picture on the link they look like spacerless bearings (as they have effectively a spacer built in) however if they do need a spacer and you haven't fitted one then that would cause this problem.

Other things I would be checking

Are the bearing outers fully seated

Is there any damage to the seat in the hub

If everything appears in order and you have not changed the hub then I would suspect the bearings themselves. If you have tightened the nut such that the wheel is locked then you have likely damaged the bearing in any case. If you can get a genuine kit.

It is the one with the reverse threads! I would have thought the torque wrench would still work both ways though  

[yeti21586]

yeah i thought they did as well but not all of them do, so be carefull

Check that the outer cups of bearings are fully seated in the Hub, if they are, I've found with these non-genuine bearings they are tight and tighter than they should be at that. I fit a timing gear shim (or sometimes two) between them.

 

But, I'll just add that I've never had good life from them, (though shimming helped) and I stopped fitting them years back.

 

<Edit: Over-torquing them shouldn't cause them to lock up, might damage the nut though. The wheel bearings have a built in spacer between them to set their pre-load, once the bearings are in contact with each other, tightening the nut doesn't bring them any closer together.>

What type of torque wrench?
Does your 1/2 ins drive part (the bit you put socket on), push through the other side to use on left hand thread?

[KernowCooper]

Remove them and send them back as not fit for purpose, the inner races which go back to back when torqued are not in spec, fit Timken and you wont have any more issues.

The type of Torque wrench I have is as follows - 

 

http://www.screwfix....ue-wrench/18289 - I believe it does but further investigation will be performed tomorrow.

 

I'm not sure fitting Timkens will make all that much difference, especially when it looks like the minisport's are pretty much cheaper clone versions. 

 

I'll provide some more info tomorrow as i'm going to have a proper stab at it.

As has been already said, fit Timkens and send the defective products back for a full refund. If they have been loaded to the point of locking up they are ruined anyway, so don't try to use them. There are a lot of improperly made, and ultimately dangerous, bearings on the market. That will only stop when the demand for refunds hits the suppliers profit margins hard.

I think you'll find they'll make the world of difference as they'll actually be the correct bearing. The ones you have are not.

Maybe it was just my refusal to admit it then. Would have thought a reputable shop like Minisport would have sold decent-ish products. 

 

I'll get some Timkens bearings. Thanks for everyones help, will keep you updated.
