So I have been moving the pinion out 0.05mm at a time and the pattern is moving to the center of the tooth. So now I am at a pinion depth of 66.465mm, 0.155mm farther out than it calls for. Backlash is 0.20mm and 0.17mm is my spec for this gear set.
I do have a stack of shims under the bearing retainer plate now, 60mm (The case was machined during the bearing hole repair). I dont think I want to go much more even though the pattern is coming. Does anyone know what way the pattern moves under load?
I am not sure if I should adjust the backlash in at this pinion depth or go back closer to the disired pinion depth and not worry about the pattern.
