OK more success, my new hubs arrived yesterday from Melbourne Trailers and Caravans, 9" x 2" mechanical drum hubs 5 x 120 PCD with 14mm x 1.50 pitch studs, will fit them this weekend:D

Well I spoke too soon:twisted: the hubs they sent me are wrong, they are basically too deep, instead of being 9" x 1.75" they are 9 x 2.75", because of this, the hub won't go back far enough to allow the bearings to seat on the stub axle, it only goes back as far as the backing plate.
Now I'm assuming that there are longer stub axles, the stub axle I have is 5. 25", which I assume is standard for mechanical brakes.
What is weird, the backing plate and pads look like they are for a narrower hub.
Is there an axle with a longer stub??

Bugger.....I assumed it would be a standard stub for the type of bearing fitted hub
From the pics it appears that your backing plate brackets are not up against the square section of the axle. My van's old 10" hubs for a new axle that I had made recently require the bracket to be against the square section. Are the new linings 2 1/4"?
It is Graeme, I made sure that it was hard up against the square section of the axle.Quote:

What size is the axle across the flats - 40mm or 45mm?
Edit: your stub axle is standard length for standard hubs.
No they are Ford bearings, the axle is 45mm, the hub is wider than a standard 9" hub, what is happening is the hub is too deep and the backing plate is stopping the hub from going all the way back so it can seat onto the axle, with the backing plate bolted onto the axle, it falls about an inch too short, the hub rests on the backing plate, I can only just get the nut onto the axle.Quote:

How wide are the new shoes? If only 1.75" then perhaps the 2 1/4" backing plate is shaped to sit back further on the bracket. The hub looks normal width for 2 1/4"shoes.
Edit: I've just looked at the old 2 1/4" backing plates from my van and the plate is dished to move the shoes further back towards the springs. I'll load a pic ASAP.
Can you compare this backing plate to your ones to determine if this one is closer to the springs?

If this is the cause then I expect they will swap your backing plates for 2 1/4" ones.
Edit: I reckon from one of your pictures that your backing plates are flat as a mounting stud and nut is clearly visible which would not be visible for a 2 1/4" backing plate.
These photos might help, the bearing housing is 3/4 of an inch lower in the drum, if it was level with the outer edge it would be fine.
