I asked a friend who has shot peening equipment to treat my gears, but he asked me about the hardness and size of the *****.

Does anyone got a clue on this? Also, should he shot the whole gear or just the teeth surfaces?

Have you looked into nitriding or heat treatments? Shot peening works fine, but at least at an OEM level, surface hardening methods like cyaniding, nitriding, laser heat treatments, etc. are more common. I'm not sure how many places will do laser heat treatment, but general heat treatment with an oxyacetalane torch or nitriding/etc. can be done on a much smaller scale at a reasonable cost, and will give you the hard surface finish (probably about 0.01-0.03) while keeping the toughness of the gear center. A lot of places that do machine work should be able to help you out with these, as its fairly common for OEM crankshafts, transmission gears, etc.

Sorry I can't help you with the shot peen sizing, but at least you can now look into other options.

Shot peening for friends has a reasonable cost

For example, a friend made a CNC Torque Plate for me for free. I just gave him the T6061 block. Great guy!
