Question: how to calculate distance between two gears?
Answer: Calculate the Pitch Diameter for each of the two gears listed above. Step 2.) Add the two diameters and divide by 2. Divide by 2 Sum of both gear diameters = 4.0”/2 = center to center distance = 2” (This is necessary since the gear centers are separated by a distance equal to the sum of their respective radii.)
