Ya, I asked a while back why they didn't pin the pinion to the coupler, it was said so you could shim the pinion out a little if needed. I may not have gotten all the oil out before loctiting it. I used some different blue from Mercury adhesives, will see if it holds now. I don't like using red on any screws that use a 2mm socket, but can if needed. Just have to heat things up to get it apart usually.
