Most of you probably already know this, but for those who don’t…If you want to service your own reels, and in particular the 2020 Shimano Vanford 1000 as well as the 2019 Shimano Stradic FL 1000, you are going to need a 0.9mm Hex bit.
It should be pretty self-explanatory but it is something to be aware of. By removing the hex screw it grants you easier access to the 12mm Rotor Nut (Part# 20999). The body is held together by Torx T6 and T8 screws.
Go slow and use a well lighted workspace and you should be fine. The only fiddly part I ran across was getting the rotor nut (Part#20999) and the rotor lock nut plate (Part#19926) into the correct position to reinstall the two screws (Part#19989). I did take a picture of the position of the rotor nut before I removed it and that helped. The reel comes with an exploded parts diagram which makes it easy to follow along. From what I could gather, the internals of the the Vanford and the Stradic FL were identical. Only the body was different.
Hope that helps!
