Bryan,
I found this on YouTube it is quite a good explanation.

The lower two diagrams on your post show high and low contact areas on the tooth, said to be noisy.
This has been my problem although the wear pattern on both gears looks even along the length of the tooth.
How does one eliminate this, as moving the crown wheel in or out affects the backlash, does this also then affect the height of the contact area?
Could someone please explain how to achieve the best height?
Roger
