If the seizure is between the inner vertical face of the sprocket carrier and the hub centre (where the cush drive rubber nipples stick through into the brake area)? Is that where I should apply heat?
K2-K6 - no, unfortunately I haven't got access to a slide hammer but will make some kind of jig

Just looled at schematics and see now the area of seizure and hence where to apply the heat.
Ironically (and don't shout at me!) I think I threw a spocket carrier away (I think, as I can't find it in the shed) that may have been off a 500 - as I built the CR750 Rep from parts and bought a sprocket carrier that by the time I got round to fitting it, realised it wasn't for a 750 but didn't know what bike it was for - was kicking around for years in the shed and got naffed of with all the mess in the shed so sold and binned loads of parts last year - hindsight!

You need a sprocket cover Phil. It has a seal in the middle and a large 0'ring to keep the shite out.

I have the sprocket cover Graham - just re-zinc'ed it yesterday

Sorry Phil, I thought you said, you throw it away but, you were on about the carrier ;D
philward:
Success - bit of heat, lump hammer tapping against sprocket (oppisite direction) then bang against old sprocket teeth using large bar through spokes - then it popped out. Phew!
The carrier looks oily on the surface that normally seizes - does that looks ok?
deltarider:
Looks much and much better than mine. No comparison.
