”The hardening” you mention is actaually a suface treatment allowing the gears to get a perfect surface when running in the gears. The result is the shiny surface you see which create perfect conditions for an oil film in the gear mesh. This gives a long gear life with a minimum of wear. These gears are case hardened and the depth is not affected by the running in process.
