Diamond Drive Gear Ratio Formula

This formula is to figure overall Diamond Drive ratio only, this does not take into consideration such variable as clutch diameter or driver size.

The formula is as follows;

Transfer Gear / Input = A then A x 2.24 (Planetary Ratio)= Overall Diamond Drive Ratio

Example:

68/52 Gears. The 68 is the input gear (always listed first, clutch goes on this gear). The 52 is the transfer gear so….

52 / 68 = 0.764 x 2.24 = 1.71 Overall Diamond Drive Ratio
