Here Here! If your reel is broken sorry, ignore me. If you just need a deep clean and lube, save your money and buy grease from Cal's Lube from wherever (I like the ...X products i.e. Speed X Reel X) and a few extra parts from Charkbait or wherever and open the tutorials. I maintain all my reels. Soon I will be breaking apart my new Makairas to service them (wish me luck)SavOn does it in-house. To be honest I haven't had them do mine but I buy parts from them. Newells are really simple (unless you break something). Why don't you read some Alan Tani tutorials and see if you are up to doing it yourself? I do all of my own and they always perform better than they started. If nothing is broke you will need drag washers, grease, drag grease and most likely bearings and oil...all readily available. Do read the tutorials before you begin. Good Luck.
I have been fishing Newells for almost 30 years, and servicing them for almost as long. Simple reel to tear down, and they really work better if serviced often. Newells need to be kept clean and free of any salt and old grease to work best. I do all of mine at least two or three times a year, and before any long range trips.X2 on what everyone else said, use Alan's tuturials or download a schematic. Newell's are one of the easiest reels to do. I personally will take a brand new out of the box reel and strip it down, get personal with it and hod rod the son' bitch.
