Increasing wheel centre bore...???

[bulletz]

Is it ok to increase the centre bore on steel rims??

If I was to do this it would mean removing the lip around the hole and I'm not 100% sure that i'm happy about that??

Any ideas??

[BlownCorona]

could you get it machined and re swaged?

[tortron]

i wanted to do it

general consensus was dont

milling hub down an option?

[Kelvin]

I did it, used a hole saw just bigger than the lip in the centre of the rim, you carnt even tell its been done.

i milled down the hub, its not ideal if you want to change back to other wheels

[bulletz]

Did a bit of digging round and didn't really come across much opposition to this. I thought I would have?

I'm looking at doing this for my kombi and as far as I can tell the wheels are not hubcentric so all the lugs will take the load anyway. But in saying that i'd machine them to a good fit on the hub

I'd rather increase the bore of the wheels then to take some meat off the hub itself.

I'll check with my cert man and find out for sure and let ya know what he says.

on a wide 5 lug pattern? or is this something on adapters?

[Vintage Grumble]

I've been told steels can crack from the stud holes into the center hole if you take out the swage.

na its a '79 bay.. 5x112

I may be onto something. Merc Vito vans have the same pcd/centre bore and come in 16" too.

That's all i'm after is 16" or 17" steelies

I've been told steels can crack from the stud holes into the center hole if you take out the swage.

That's what i reckon as well. So instead of machining them and then adding a new lip i'll give these Vito wheels a bash

yeah 90% sure most lateish merc wheels fit nicely on bays

wats the best way to mill down a hub? 
If one doesn’t have a mill, but only an angle grinder and other tools, pay somebody else? 
 

Wheels have a CB bore of 56.1mm, hubs are 56.5mm. .4mm shouldn’t matter too much?

Flap wheel on a power drill use a fine grit one go round and round refit frequently to ensure you don't go over.

Probably take 5 minutes.

[Raizer]

Got the hubs off the car?

 

/Won't take fuck all to take .4mm off with a flapper though.

[87creepin]

They’re still on the car, sweet will be super gentle.

Just whip it out and add a rubber washer, bang it back in.

What torque do you suggest?

[Bling]

Use a hand nut driver in left hand for soft compounds and right hand for harder compounds. One click on old man wrist for correct torque.
