Salmo S4000 reel

[Jivko]

Hello, I decided to service my reel by cleaning and greasing it, but after reassembling it, there was a metal washer left, which is the same as the ones that fill the gap on the gear wheel (crown), but when I put it there, the reel has a hard ride and rumbles, it takes up too much of the gap and I have no idea where else this washer could be. Does anyone have any knowledge of this reel model?
I apologize for the bad English.
