You have to get the pinion gear as close to the spur gear as possible but still allow for a VERY small amount of movement with the spur. You should be able to wiggle the spur with your fingers just ever so slightly. Usually the trick is to put a piece of paper between the gears, push them together, tighten the screws and then pull the paper out. Check for a small amount of wiggle room with the spur. If there isn't any, fold paper in half to double thickness and try again. But the important part is that there is a small amount of wiggle room between the gears so they don't bind. شاهد المزيد
