Hi Grumpy and Kempe, well spotted grumpy, I looked at the end of the shaft yesterday and thought the same....methinks foul play!
I also agree with you on a good soaking with penetrant, according to the advice I have received, it should slide off revealing the keyway.
Kempe, could you please take some pics of the roller-half when you get the boss off, for archival purposes it will come in handy for future reference....Thanks mate.
Plus the fact we would all like to see what's behind the ring gear....he he...
