No extra parts, so the sleeve isn't the issue. By right side plate bearing do you mean drive shaft bearing (key24 2 req)? What's the best way to deal with the lever drag/preset knob when servicing these reels? Do you set them to free to avoid miss-alignment? What should the max drag be on this reel?
Took everything apart, re-assembled with considerable improvement except for random grinding after pulling drag while testing settings. Handle still seems hard to turn when full drag is applied, and as stated; random momentary grinding sound after spool/drag pulled. It goes away after 2-3 cranks? I think it might need a few bearings. The spool & brake bearing looked rough and this might explain the symptoms. Again its not my reel, like you I have the illness/obsession of tinkering with reels only I'm @ stage 1 !
I will probably call Avet in the am for guidance and order new bearings.
