DriverZA1 = 18
DrivenZA2 = 61

i = Z2 : Z1 → Remark
iG = Gear ratio = ZG 2 : ZG 1 = 29 : 39 = 0,744
iA = Final group gear ratio = ZA 2 : ZA1 = 61 : 18 = 3,389 in total
itotal = Total gear ratio
itot = iG x iA = 0.744 x 3.389 = 2.520
1)  Z1 = Number of teeth of drive pinion, Z2 = number of teeth of driven pinion
