[TD]I bought a new bearing carrier for my R (1987), and the outer seals don't touch the seal surfaces on the sprocket hub / rotor hub. Was there different diameters over the years and someone has a different axle in it?[/TD]

If I know what the diameter is supposed to be I'll just turn it down and machine a ring the correct size and press it on. So... if anyone has a fresh hub laying around that they can mic the surface of that'd be awesome![/TD]

Sprocket hub looks to be 52mm or 2.047" in diameter

That is bizzar.  Mine mics out at around 1.875.  Thanks much, I'll machine a ring for it.

What Brake Rotor Hub are you using ??? 250R & 450R are the same at 52mm Diameter. Give us a pic if you can. :)

I honestly have no idea. It has an adjustable axle in it, but I'm assuming it must be from something else... 3 wheeler maybe? Who knows. I'll try to grab a pic on my lunch break, it's in the back of my Jeep.
