Any tips for getting this bit off?

Heat, and judicious force

Hydraulic press. There must be a local garage engineering workshop that'll happily do it for you for little or nothing.
I actually considered that, but I'm inclined to think that will shrink it on even more.
Yeah. That's my last resort.

I thought i'd done that, but I may need to up the ante on both
Liquid nitrogen; local chemist for the stuff that freezes verruca's.

Correct!
Skinny Cutting disc at an angle across the face and around it and split it "On a Block of wood" rather than steel or concrete!
I don;t know how the F*** they get so tight but they do and they go bang and bits fall off I now Cut them
I think I hve one removed and I can at least show you the shaft
20tonne press on the bottom. They are tight don't pull it on the top ring it will shatter.

Measure it , sometimes they are not worn much and it just isn't worth the hassle changing them.
Best done before you have bought the expensive bearing / sleeve and pulled the rest of the shaft apart, off course ------------.

I have a thick steel plate with a hole bored in it that matches perfectly. sit it on a hydraulic press and it comes off easily with gentle pressure.
Lambretta crankshaft flywheel side bearings are a similar set up. The diagonal cut ( I use a Dremel) and a cold chisel to finish it off works for me every time. I put a Jubilee clip over any part I don't want to risk damaging. In the time it's taken me to type this it would have been off!Correct!

Paul.
not shown the worst side in my photo. but it has some nasty wear marks.
Yup - That's what I do too (I have a box of 'special' tools I have made over the years). It doesn't require enormous force, the dial on the 30-ton press hardly twitches

Not having a 30-ton press to hand, I went with Solidstate100's more rustic approach 
those splines look a little sharp.
I have nothing to compare it to, but I'll have a closer look at it later.

Rustic usually works - Its the airhead way
