In my experience the only practical way to compare the different setups is to mount them properly on appropriate stub axles and then measure the overall dimensions. With the variations in the different hubs and stubs I found it too confusing just trying to measure things individually.

That is what I did, I fitted D1 hubs to my drum brake Defender stubs and ended up with 10mm narrower track per side but I'm assuming the axles would have been the standard length Defender.

Is there two different offsets of Disco 1 hubs (in the narrow bearing spacings)?

Diana

Thanks Steve. Do you know how long a long axle is? Mine have a 'H' on the ends and are maxi drive ones.

Not sure about Maxidrive ones, but I recall seeing an axle dimension chart on the Ashcrofts site.

Edit: Here you go.. Ashcroft Transmissions

All the D1 hubs I've got here are the same.
If your defender drum stubs are the type with the thick spacer/seal land (like the on on the right in this photo) they don't go with D1 hubs. Only useful for drums.

EDIT: Stub on left is FRC3132, one on right is FRC8540

To go with D1 hubs you need the FTC1740 defender stubs which don't have the plain portion for the spacer to sit on, but have a step which places the stub further outboard (by coincidence about 10mm). Take a look here:
FTC1740 REAR AXLE STUB ASSY | shop | www.lrseries.com | L. R. Series
You need later (short) defender axles to go with that combo.

Is this the thick spacer/seal area I need to look out for?

Addit: Bugger my VIN is an HA90... not an LA93...

at 1/6 the price of Genuine are the Britpart ones worth taking a risk with?

Yes.

I knew I had a photo around somewhere showing the 2 stubs together.

Hi Steve

Just clarifying what you're showing us.

FRC3132 (at the top) is an early 110 wide bearing spacing stub axle.

FTC1740 (at the bottom) is a late Defender narrow bearing spacing stub axle?

Both would use the same length half-shafts as my early defender stub axle.

I'm starting to feel like your signature line....:angel:

What would be good conclusion to the thread is if someone could find the part numbers of the early Defender rear disc hubs and stubs. I'm guessing that they will suit the early (long) axles, likely mount onto the FRC8540 stubs, and retain the standard track.
They may also be like rocking-horse poo with a price to match, but that's OK as I don't need any :D

Steve

You're not wrong there, ATM I'm in the situation of having to buy 4 x FTC1740 stubs and 4 half-shafts to keep the track correct. :BigCry:
