magneto drive gear

[FORANE]

Can anyone tell me the part number for the magneto drive gear on a slick magneto #4370 and 4373 to be used on a Lycoming o-320?

Now, this is for the E2D and E3D engines. There are a lot more O-320 models. Just Google "Lycoming O-320 Parts Catalog" and you will find numerous pdf's you can download. Free. Many are direct from Lycoming.

This one is https://www.lycoming.com/sites/default/files/attachments/O-320-E2D%20%26-E3D%20Parts%20Catalog%20PC-203-6.pdf

Magnetos are found near the end of the catalogs.

I have a backup set of mags that I sent out for overhaul. I figured mag overhaul is likely better done by someone experienced than by myself. They just need gears. I am looking to buy a set of gears for them. I hadn't looked up the torque specs for the gear nut yet; does anyone know that spec?
