Taking it out and apart is no problem, just what (or not) to use to lubricate it was what I wasn't sure of. I'll pull it and see if I can clean it. But it may wait till these 100+ degree days are over. I just unhooked the cable to it for now. (Yep, I'm a wuss in the heat.)

I appreciate the suggestions. I can see where lubricants might cause problems down the road. Especially down our road which is dusty to say the least.
