… my impression was that the gear shaft had a keyway which runs right to the end of the shaft and is visible on the 'fastener' in the last photo. The gear is prevented from rotating by a key held in place by one of the grub screws. < etc. >

Agreed

Mike/Michael – you are right!

Mike – I'm sorry I misunderstood your first reply – your interpretation of my pics was right on the money. I feel foolish now – after having come to the conclusion that the pinion must be keyed to the shaft I should have realised that the keyway has to extend to the end of the shaft – the boss visible at the botton of the above is welded in place, so no way was it coming out in that direction .

It was actually worth pursuing the strip-down this far – the shaft is bored to allow lubricant to pass to both bearings, and it was pretty much caked up.

So another result – thanks!

Excellent result, Robin … and it appears that nothing was harmed.

… That makes today a good day

Nice to see a successful operation perhaps you can give us a picture or two of the finished machine.
