gear pitch help

I have a gear box.  How do I know the gear is which pitch???(32, 48 or 64 pitch....)
I don't have manual and all I have is the reduction ratio 3:1, propeller diver distance
and number of teeth.  Any brother knowns about this??

雖然唔知你圖中件東東係乜 , 但其實你可以試下用番 32/48/64 pitch 齒放上去度下就知 , 如果 pitch 不對 , 係無可能轉到一圈 !

Courel500 thanks for the information.  This is a gear box for bushless motor.
So what to do if I have no 32/48/64 pitch 齒 !!!
