Think I solved it. The fit of the geared piece must have been dry or hanging up on something. Sprayed some wd40 on it and works as it should.
Good to hear if it lasts.....that gear is sealed from the inside, so unless you got lucky and don't have a good seal (?) I'd say you're good to go until it sticks again. I'll try posting pics of when I tore mine apart, cleaned inspected, re-built, and lubed and re-installed it to give you an idea of what it looks like inside....
Ok, here's a URL to my Photobucket library....sorry, I don't know how to load individual pics from it yet. I'm going into it either this weekend or 4th of July weekend to re-lube using the correct White Lithium lube. I'll try to upload pics from my phone.
You can get an idea of what is inside the sensor. In a nutshell, I couldn't get any lube into the sensor and ended up doing quite an extensive mod of it. I have to say that for $100 bucks you can get a new sensor.
This is a safety critical component and I won't be held liable for what you do to yours, but I have had great success with this.
It took a while to find the right lube (Krytox) but now it will work good last long time, and I can clean and re-lube when needed. The problem with this thing is that it is made of Glass Impregnated Nylon which is great stuff, but the glass fibers will eventually wear and cause the binding that you feel. It's probably the best material to use in this situation and I don't think it is a quality issue.....it just is what it is...as long as you can find a quality white lube I think you would be fine.
