I think , hopefully, that the problem has been resolved! Having removed the gearbox sprocket, I was able to compare the mainshafts on my 2 boxes. There seemed to be a spacer on the problem box where the shaft emerged from the g'box case.Can this be removed? No.Well if it won't come out will it go in? A gentle tap with a round punch and hammer seemed to show a slight movement ....Hmmmm! Then it became clear - it wasn't a spacer, it was the bearing which at some time had been replaced - I bought the box as reconditioned - but not fully pressed into the case. Gentle application of brute force resulted in the bearing moving to become flush with the casing - giving me more of the gear sleeve which now supported the chaincase oil seal. I have yet to reassemble everything, but hopefully matter resolved. Many thanks to everyone for support and advice.

Hi

The miscreant item in your photo is part number 040131 - spacer gearbox sprocket, which also functions as the inner part of the output bearing oil seal. They can/should be a little tight on the sleeve gear.

Fiting the sprocket and tightening the nut would be a more 'sympathetic' way of seating the spacer

Onwards and upwards

The problems it has caused rule out any form of sympathetic response! I did only use a gentle approach - only a medium sized 'knocking stick'
