Managed to get this sorted yesterday by getting it turned down, now at 34.945mm. I Also tried south lakeland minis as I know they have genuine parts, got them to measure there's and theres was 35 mm as well. It seems that all the ones the suppliers have are oversize, maybe needed a second regrind at the factory but they never got around to it?
And tapped the bearing on.

For your own reference (and maybe to show some of the suppliers), I've just broken open a new Factory Crown Wheel, though of a different ratio to what you seek and this is the Bearing mount size (in imperial of course!)
Thanks for doing that, It does read just over 1.375"? Took a while to read an imperial mic
1.3755" to be bang on, not sure off hand what that is in new money.

Well,,,, that looks better !!!
I often wonder if in the very late years of Rover, knowing that it was all going to be wound up sooner or later, if parts when found on the line to be out of spec, instead of being sent off for re-work, were sent off to be sold as spares? I know this is a bit 'out there' but so much of the late OEM Rover gear was off spec. I managed to get a hold of one of the last boxed Rover Primary Gears a few years back. You beauty !! When taken from the box, the running clearance to a new crank was 0.014" !! Hmmmm,,,,,,,,,,,,,,,,,,,,,,

Wouldn't surprise me, I wonder if the yellow mark means it needs re-work? Wow, that's a lot of clearance
