Please see Page 189 for more details.② The backlash of racks differ depending on the size of the mating pinion. Please calculate the backlash from the backlash value of the mating pin-ion. Also, please refer to the data in the section called 'Backlash of Rack Tooth (Amount of Tooth Thinning)' on Page 191. [Caution on Secondary Operations]
