Everything was easy. I followed Roberts instructions from a previous post
You have to make sure that the 'step up' portion of the gear is in front of the sensor. It is easy to check. I had a small measuring tape I was able to stick in there to measure. I did not have to rotate mine as it was already at 1 15/32. They give you a small pad that sticks to the end of the sensor, that actually sets the gap between the gear and the sensor.
