So your Differential Constant will be: [Lead Gearing Ratio] X [Gear Lead] X [Hob Starts] / [Gear Teeth] The differential Ratio used for the test gear was 68/58 X 60/79 = 0.8904408555 Differential Constant = (0.8904408555 X 26.528205) / (3.1416 X 24) Differential Constant = 0.313293817 This value is very close to an industry standard value derived from the formula 25/(25.4 X pi) = 0.313297132.
