Got the old wheels off (with difficulty) and the borrowed ones on.
The bearings on the wheels off my friends Willerby are the same internal diameter.
The caravan mover did say that they have some various spares that they can use if necessary.
I had to hammer off the old wheels and the inner bearings stayed stuck on the stub axle.
One subsequently tapped off with only the dust covers popping off, but the other turned to shrapnel and I ended up bashing the inner ring off with big hammer and cold chisel!
Ground underneath is very soft fenland black soil and getting something stable under the bottle jack, on my own, was a struggle. I had various lumps of wood and a thick steel plate, fortunately, but due to problematic placement I managed to bend the axle slightly!
Rest of the frame seems solid enough though.
Hope the movers are well used to this sort of thing, that’s certainly what they charge for!
