I've searched and I have found a lot of good information but I have a few questions that still looking for clarification. The reels that I will be tearing down, already have one partially tore down, are Shimano 16 Scorpion reels bought used on the jdm auction sites. I know for the most part grease goes on gears and oil goes on the spool bearings but I know some of the other moving parts should have a light coating of grease and that is the part I am trying to figure out. I have tsi 321 for the bearings and will probably use that on my level wind also. I have read that gear oil can be (should be?) on the handle roller bearings. I would like to clean all the old grease off with a tooth brush and dawn or simple green and start fresh if possible, just not sure where on the frame to apply grease.

 

I know there are various opinions on grease etc, I will be using Cals for the gears and other locations needing grease and then tsi 321 for bearings and level wind. Since I am still learning the name of the parts if referencing an area that should have light coating of grease if you can reference the number in the diagram so I know what area. 

 

Thanks

Any part that sees metal-to-metal friction should have grease on, but grease will hinder rotation speed. So for me, spool bearings and the AR bearing are the only parts that see oil. You can put oil in other bearings as well, to achieve a free rolling feeling, but I personally prefer longer-lasting grease in those bearings.

Thats pretty much what I have seen but forgive my ignorance since I am still learning, I know which bearings are the spool bearings but which bearing is the AR bearing. On the diagram there is one number 68 and one numbered 26, I think it is 26 but wanted to make sure, thanks.

On this reel, spool bearings are the two #24, which should be lubricated with thin oils. 68 and 26 are the pinion support bearings, and 28 is the main shaft bearing. These three bearings can be lubricated with grease or oil; the choice is yours. Whichever you choose, just don't overfill 68 and 26 with lubricants, as they may spill inside the pinion gear and on the spool shaft. That would affect the casting. 

 

Anti Reverse bearing is #31, the big one. You may not be able to remove it from the frame for deep cleaning. In that case, you can either soak it in Simple Green with the frame, or just fill it with a few drops of clean oil to flush out any debris. After wiping clean all the oil along with debris, you only need to apply maximum two drops of oil in it. This bearing is a bit tricky - both too much oil and too little oil would cause it to slip.  For this generation of Curado/Scorpion, I believe Shimano recommends against putting oil in that AR bearing during regular maintenance. But I find that after deep cleaning, a drop of oil or two inside would be beneficial and necessary.  

 

Good luck and have fun!

Thanks this helps a lot, really appreciate you taking the time to write this up.

 

This is what I was going by @Delaware Valley Tackle he made a post and stated "Tsi321 on spool bearings, AR, 80-140 gear oil on frame bearings, sliding parts and level wind, marine grease on main gear, spring washers for drag tension, drag grease on drag washers. "

 

Being such a newb to the internals components and what they are this helps, I think I need to find some diagram that calls everything out. The schematics just reference all bearings as bearings, lol. I ended up tearing one reel all the way down and used dawn and cleaned everything. Dawn doesn't appear to be the best but was still able to clean things. I bought a cheap ultra sonic cleaner for the bearings and that appeared to be a bust, lol. I soaked them in acetone then spun them lightly to make sure things were cleaned. I used tsi 321 on all the bearings except now that I know the AR bearing which I used 90wt gear oil. Now that I know that is the AR bearing I guess I should have used tsi 321 oil but the one thing that I wasn't sure about was how to oil them properly. The AR bearing is pressed in and it does come out fairly easy but its different from the smaller ones that I can spin and not sure how to oil it and distribute the oil around.

 

Reel is back together and seems to be smooth and work but took me forever, lol. I have a better feeling for the parts now and how they go together and the next one should go faster.

 

Thanks again for the information.

For ar bearings, you don't have to tear them apart to clean it. After cleaning, just apply a couple drops of oil from the inner rim, where you can see all the tiny pillars. Use a q tip or small brush to make sure the oil is applied evenly. That's about it. As long as it doesn't slip after that, you're good; otherwise, you can wipe clean the oil and do it again.

 

For bearing cleaning, I find an ultrasonic cleaner very efficient. Several minutes of ultrasonic cleaning with acetone do a better job than an overnight acetone soak.

 

As for levelwind, some believe oil is better, as grease attracts dirt. But that means you'll need to apply oil to it on every trip. As a lazy person, I use grease on them, and so far so good. 

I can and have dropped the motor and tranny out of a 1981 Porsche 911.  I have even rebuilt a Rochester carburetor somewhat successfully.

 

having said that, that tiny parts schematics of a reel is daunting.  hah.  I cant and won't dig that deeply into a reel.  truth be told, I cant even tell you how the knobs on a casting reel come off and on.   DVT has a reel of mine (I HOPE!!!).  I'll let him perform the work.  because that Rochester Carb sucked....
