Penn 460 Slammer Reel Maintenance

I want to open my reel, clean and re-grease and oil it. Could you recommend a thread/link that would give me a tutorial on cleaning and greasing a reel. I have only had my reels for a year or so. I got a penn 460 slammer that I want to get back into top notch shape. Never have done this before. Any help is appreciated. The reel feels like it no longer has grease inside when I spin. Goes much to fast, like a bike in a high gear when there is very little if any friction. It has only been used one year.

BTW, I bought two items, Penn Precision reel grease and Penn Synthetic Reel oil.

Is this a difficult or easy reel to open and do a maintenance cleaning on?

If we are near by each other I'd be happy to show you how, it is a well built super simple reel to maintain
