MG MGA - MGA / MGB frt ww hubs

Will a frt ww hub from an MGB fit onto a 1957 frt ww hub MGA?


Gordon Harrison

No.
MGA & MGB are different bearings, brake parts, and threads.

This is where I get confused. I have bought the hub shown in "THIS" picture and it said MGA/MGB hub. By looking at the picture is it possible to determine which hub it is?


Gordon Harrison

Here is a bigger picture....I hope


Gordon Harrison

Not sure, it does look like an MGA hub, but I think the MGB hub looks pretty much the same. I am guessing that the difference is in the bearing sizes? Pity it's not a rear as they are quite different between MGA and MGB. Does it match the MGA discs? (it's definitely not an MGA 1500 hub)

I have told the seller to send it along and I will try it. To me it sure looks MGA.

MGA thread is 12 tpi, MGB is 8 I think.

Drum brake WW MGA has six studs to retain the drum.
MGA has 20 & 30mm ID bearings, MGB had 1 1/4 & 7/8
MGA & early MGB have 12 TPI, later MGB from about 65 have 8TPI.

This is NOT an MGA 1500 drum brake hub. It MAY be a 1600 disc brake WW hub, have to check bearing sizes.

FR,
I hope you are right ,as I want an MGA WW Frt hub. Now all I need is to find another one for the other side.
Gordon Harrison

Gordon, note that they are handed!

I have not received the part,at the moment. If it is the proper piece,I will keep it.So far it seems to be waht I need. I did find that The Little British Car Company, has new repro ww hubs,at the least expensive price. They are asking $127.00 brand new. That's a very good price,and if I cannot find the opposite side,I will buy one from them.
Gordon Harrison

The hubs are totally different.
All MGA except Twin Cam use ball bearings. MGB uses taper roller bearings.
Bill Spohn

Just a final thought. The orgional MGA Frt WW hub has 6 holes,for use with drum brakes. In a conversion to Frt WW disc brakes,the hub has only 4 holes. Therefore do you think it would be possible,(for a competant machine shop) to re-drill the 6 hole units with the 4 hole application. An important factor here would be ensuring the safety of the hub, IE: to many holes...reduced strenght, extra stress etc.
