MG MGA - wire wheel splined shaft kit

Hi I've just taken the rear offside wire wheel of my mga for the first time.



Gasp !! the wire wheel is attached to a bolt on splined shaft, this is obviously some kind of kit. Ok no problem ?

Problem the wire wheel is pinned against the studs from the drum and not an interference fit on the spline (see picture)

I'm worried about driving it like this, has anyone else had experience with theses kits , is mine fitted right, should I grind the stubs down ?

HELP any advice would be much appreciated

Kind regards Jonathan

I am trying to work out what you have there.

I converted my 1500 disc wheel to WW, retaining the disc wheel axle. My kit came with shorter bolts and narrower nuts. This is what mine looks like. No interference with the WW.

looks like yours are bolted inside the drum, maybe slightly different kit ?
DJ Joy

Standard set-up. The bolts pass through the hub assembly, the splined hub and the drum in that order.

Mine has K209 LH Stamped on it

Heres a another picture it might help

You have a wire wheel conversion kit mounting, similar to what would be used to convert a steel wheel car to a WW car. Triumph s use this type of mounting for the conversion.

It looks like it may be some form modification to adapt a non-MGA splined hub.

Not sure what to do, I wonder , looks like the original studs and nuts have been used, do I need shortened studs and nuts ?

It is a steel wheel axle fitted with conversion hubs - the nuts should be half height with shorter studs.

Looking at my invoice from 1999, the shorten bolts and narrower nuts are available from Moss. I used their ATB4124 bolts (8 off) and FNZ507 nuts (8 off). It is very likely I may have hacksawed off any protruding part of the stud after fitting the nuts.

Your conversion looks different to mine but those items should do the trick, fingers crossed!

In fact you may get away with just cutting off the protruding bolt shafts.

Now I AM confused!....
A photo of the stock WW setup would be very helpful....

For a disc wheel conversion to WW for a 1500 mine is probably the most common, utilising Moss parts whilst retaining the longer back axle. It is (externally) as shown above. You can view the innards in the exploded diagrams in the Moss catalogue.

Edward, stock WW setup is the splined hub is a press fit on the half shaft. And the axle case is 2" less wide

Then this image shows an "original" WW installation?

Edward, no mystery there. Those are Triumph TR2-6 wire wheel adaptors bolted onto a steel wheel hub. You widen the track width slightly but it works just fine.

Here is a picture of one one I use on my Jamaican MGA.

I didn't want to saw off the studs so I just made up an alloy spacer so that the conversion was easily reversible.



Bill Spohn

So it looks like three options

Cut down the studs

Replace the studs

fit a spacer

Hmmm
DJ Joy

As I mentioned before ,it is a conversion kit so you also have the choice of RE-CONVERTING back to steel wheels. If you did that you could get a nice set of Mini lite spoke wheels and just slap them right on. It would save you all of the problems of creating a spacer or cutting the bolts. It would also give your car the correct wheel spacing.

Or even better...

Dunlop style alloy with dummy spinner for the twin cam look from Racemettle...

Except that anyone that would know a Twin Cam from a pushrod will know they are fakes....and they never used Dunlop stickers on Twin Cam wheels so another giveaway.

Hi Jonathan,

I have a similar setup to yours, but with spacers to step the hub out (I didn't want to mess about wit hte studs). The conversion hubs sit on the outside of the rear brake drum (and on the front bolt onto the front hubs). My hubs are counter-sunk so that the standard wheel bolts can be used to secure them. I can't remember who I bought them from, but it was a big stall at the Beaulieau Autojumble about 8 years ago - they did hubs for all cars.

I'm intrigued about Steve's that fit on the inside of the brake drum - I would have thought some drilling would be required for bolts or are the hubs secured by removing and then replacing the studs?

cheers,

Grant :-)

My setup is shown on the Moss on-line catalogue:

See item ATB7206S on said page.

Steve,

ah right, yours are splined (proper) - nice! Mine just bolt on.

cheers,
