Has anyone experienced, during a TR3 gearbox rebuild, where the two largest gears have taken on a brass-like color to the top of the gear teeth? The teeth all appear to be in good condition with no chips or missing pieces. I am wondering if this is normal wear or if the gearbox at one time possibly heated up.

Yeh I have often wonder what that brass color is. I have also seen on rockers, worm gears, and other hardened iron objects that seem to be in close proximity to brass. If I still worked at the university, I would ask one of the chemistry people. Perhaps there are some hard science guys on the forum.
