Great set of instruction for do-it-yourself BR maintenance:

Great tip! Thanks

You're welcome guys.

I should also have added that I actually used these instructions to perform maintenance on my 4500. It was the first time I'd ever worked on a reel and the instructions were very newbie friendly. Took me about an hour and a half to do the whole job (in large part because: a.) I was anal about clening ever last grain of sand and smudge of grease, and b.) was anal about not doing anything till I had read, reread, and triple-read when necessary, every step to make sure I didn't dick anything up by rushing). When I was done the reel was humming like new.

Of course I then proceded, like a smartie pants, to rush through my Spheros maintenance which resulted in my bail spring shooting across the room and taking all those other little bail parts with it. Fortunatley, Paul at Grumpy's runs a "reel in a bag" service for folks like me who bite off more than we can chew.
