can anyone tell me can a staightforward swap be made between a Mg midget differential and a Minor back axle

Post by **Matt** » Sun Apr 08, 2007 11:49 am

The Midget diff. is interchangeable with the minor one. However the midget axle is narrower than the minor one...

Is it narrower ? I thought only the A30/35 axle was narrow, and A40/Spridget were same as Minor.

I have always been told they are narrower. The wire wheel axles certainly are

Post by **bmcecosse** » Sun Apr 08, 2007 3:13 pm

Ahh - maybe the wire ones. Fairly sure - but not certain - Spridget steel wheel axles are same as Minor etc.

Spridget steel wheel rear axles are definitely narrower than the Minor - when I bought the Peter May half shafts I had to wait until they made a 'Minor' batch - Spridget were in stock.

Midget (steel wheel) / A35 halfshaft are the same length.
MKI A40 axle is same as A30/35 / Midget.
A40 MKII is wider and maybe same as Minor but I don't know for sure?.

going back to mollyone's question, if you want to fit an MG diff to a minor backaxle then it is a straight swap.

Well - learned something new today - because I always thought the Spridget used the complete Minor/A40 axle. It uses the Minor steering rack - so I wonder how that matches in with a narrower rear axle ?

They might do - unless they're the wire wheeled ones.

Well, having tried to fit a (steel wheeled) Midget oil seal to the Minor's rear hub I can assure you they aren't the same! Fits in the hub just fine but has a smaller hole for the end of the axle.

I wonder if that's just a year to year variation?

Hi,

I was wondering if the Wire rims on a mid 70's MG midget fit a 1960 Morris Traveler from the UK? I have the complete differential, axles, rims, brakes, and wire rims.

Measure the widths of the axles to settle this on-going puzzle!! It sounds a very odd conversion - generally wire wheels are to be avoided like the plague, and remember they were designed for the lightweight Spridget - not for the relatively heavy Traveller.

and the heavy TR6

Post by **bmcecosse** » Mon Apr 16, 2007 11:13 pm

Aye - but these ones inquestion are specifically Spridget ones - TR wires will be designed for that heavier car.

Post by **Matt** » Tue Apr 17, 2007 12:27 pm

The spridget wires should be ok, however I would look at the possibility of 14" MGB ones, they are designed for a heavier car with more power and fit on the spridget splines. I think they are also wider
