Threaded Hole In The Hub!

[Guest rick03054]

Damn it! The threads on one of my wheel bolt holes is threaded. Found this out after about 10 mins thinking it was just the disc in the wrong place! I think it's just the first few but it was too dark to check by that time...

 

Since I have the newly aquired skill of taping I'm hoping I can just sort it easily. But I dont have the right size

 

What size do I need? assuming it's ok to do.

 

This would be a far better option, but if not I have another hub with a knackered bearing. Which I previously thought was a 1.6 hub but now I'm not so sure. What can I measure to check?

 

The hub carriers are the same aren't they?

 

And one more thing Are the bearings reusable after they get pressed out?

Best of getting another hub imo.if its threaded,its likely a tap wont sort it

 

and bearings are not reusable once pressed out.

As said you need the new Centre Hub part, They differ on both 1.6 & 1.9 due to the different bearing and offset

If you want to try tapping it then you need a 12mm x 1.25 tap.

this happened to mine afew weeks ago and i tried buying a tap and retappiong it but it didnt work

 

bought another hub in the end

How do I measure the offset, is it how much the hub sticks out of the carrier?

Be aware that a standard M12 tap is M12 x 1.75, so you may need to go to a specialist to find the 1.25 version you need.

Tits! Like I say taping is a new thing to me. I always thought there could be any variation on bolt diameter-thread pitch. But after a bit of reading up it seems that mostly bolts of a certain size have a certain pitch? Is that right?

 

And this site backs up what Bassman is saying

 

So I'm still looking to find out how to differentiate between 1.6 and 1.9 hubs if anyone can help?

Most bolts do tend to have the normal sized threads as listed in that table, but the fine and super-fine threads are common amoung car manufacturers for various reasons - which is annoying.

[Guest rick03054]

And surprise surprise the f***ing wheel bolts are one of those!

I have a suitable tap for the hubs. makes it much easier to put the wheels on aswell.

dont bother buying a tap mate, honest, it wont fix your problem

[Guest rick03054]

Yeah, I wasn't sure it would. And to be honest I reckon a getting a new hub will end up not much more than buying a decent tap!

 

Can anyone tell me what I can measure to see if the other hub I have is 1.9 or 1.6?

[DaveK 0]

try measuring inside the hub where the driveshafts go though. I think if its about 35 mm its a 1.9 or if its 30/32 its a 1.6 one.

 

someone might correct me tho

 

oh no hang on thats the size of the nuts im thinking bout, sorry im unsure what size of thread the driveshaft on each model is

[sonofsam 5]

If it helps at all, a 1.9 bearing is approx 78mm OD, 28mm ID.

The hub carrier itself is app. 93mm on the OD of the flat face at the front.

1.6 & base model hubs have a solid edge on the drive fange but are different offsets but the 1.9 has a slot in the edge.

Fantastic, cheers Graham, just what I was looking for.

 

From memory I think I have another 1.9 hub then! Bonus
