What is/how do i measure the module of these bevel gears?

    Hi all,

    I've got 2 bevel gears that I'm recreating in CAD, I've got the shapes down it's just a little bit of fine tuning with the dimensions, for which I need the module/diametral pitch of the gears.

    The pinion has 9 teeth and a tip diameter of roughly 39.3mm, and the gear has 14 teeth and a tip diameter of 54.5mm. How would I go about finding the module/pitch diameter of these gears? They are straight bevel gears, and I've attached photographs below.

    mod = pcd/n

    n =# of teeth.

    as far as i know, you need one to find the other.
