Crown Wheel Question

[MatthewMyerscough]

Hi Robert

I haven't actually purposefully blued the pinion, I've only ever blued the crown wheel, like you say.

The second picture (albeit poor quality) is the blue that has transferred from the crown wheel, showing the contact pattern. In my inexperienced view it shows good contact on a large surface area of the pinion teeth, not so much towards the bearing end of the teeth which I would have thought is normal.

Thanks

Matthew
