Thanks for the images Gadi. I see that the original button head screw is still installed next to the sensor and that another screw has been added to the timing ring. Is there only one additional screw? According to designer, that button head screw retains the sensor in place. Anything else won’t. On mine, I can’t budge that sensor with the socket head screw I have in there now that does not make contact with the ring. Dan.
