Nova hub machining

[garethcolley]

How much needs machining when using astra CV's. Any one got an exact diameter?

[Benn]

Do you mean how much is taken off the big block hub flange?

You also want to make sure the top edge has a nice radus on it for the bearings to roll/sit in.

Thats exactly what i need, thanks mate.

sorry ti hijack but would i just use the flange off a 16v car?

[Benn]

Any big block flange will work yes.
Astra, Cav, Cally, Vectra.

i used an astra hub but had to get the face that the wheel touches turned down i.e the part the wheel nuts go through cos it was too thick

[Benn]

Erm... The wheel wont touch it. The brake disc sits over it...
They are all the same size/thickness.

i just said that so folk would know what side i meant. i fitted it and could not get the disk into the caliper

[Benn]

Thats very odd, was it fitted ok? All the hubs are the same thickness so you shouldnt of had that prob.

the one i used was off a mk3 astra (motorsport) and the thickness of the hub that the wheel nuts go through was a few mil thicker than the m.tec one i had in there weird i know but true i still need to do the other side

[Benn]

M-tec? Eek! and very odd.
