Unless your a tournament fisherman (or a multiday in the week fisherman) No need to completely tear down a reel. I don't fish everyday (wish I could though) I just remove the side plates handles, and spool, and clean up what I can with a Q Tip soaked in a cleaning solution, and relube, if the bearings sound cruddy I try to clean them out. Haven't removed the worm drive so no popping clips into the atmosphere. I don't remember if I have removed a E clip on any other part. It's really not rocket science. If your handy it should be fine. Just put it together the same way you took it apart that's all.
