It is not so much the root clearance you are after but the side clearance between teeth. What is the diametrical pitch or Module of the gearing? From that you can calculate the theoretical centre distance between pinion and gear. However, it may be just as good to allow about 0.1 - 0.2 mm side clearance. The DP might be 4, or 3 or so? _____
