Don't take them apart with out the manual real close Normal lub and cleaning will take care of them Fish. If you ever have a problem let me know. The guy that ran fish-ins tackle still works on them and services them.
I use a lube called Rocket Fuel (Yellow viscosity). Basically I follow the guide that was mentioned above for my Curado's and Castaic's once per year. I tear them down soaking the bearings that are easy to get to , then let them air dry, then put a few drops of Rocket Fuel on them and put the reel back together. I also lube the worm gear with white lithium grease, something I have leftover from my mountain biking days. It's pretty easy after the first time doing it!
