ok - so had a go when I got home tonight.... the caps came easily with a spoon (which made it much easier to clean
... and now the rearing race and new cone nut fits in nicely,
However, now the cap won't go back on as it sits about 2-3mm proud on the wheel. It is the same regardless of using the old loose bearings or the new bearing race. Am i supposed to be trying to fit the cap back on or does it have to stay off when using the new cone nuts?
can take a photo later if it helps.... thanks for any help/advice chaps
