felt seal #900162004

I recently bought a reconditioned ryobi one 18v chain saw to match my other ryobi stuff. I was having trougle getting the chain on it and took off a piece of felt between the sprocket and bar as I had never seen anything like thatin 40 yrs of using saws, thinking it was for packing maybe. Well I called ryobi about it, and they told me it was supposed to be there, but could not tell me what it did. I told them I took it off, and they said I could do that, but it was supposed to be left on. Could you tell me what it does, and should I put it back on? Thanks, Paul Munger

Hi pampampa,
I could be wrong but I thought ryobi used that felt seal around the bar oil feed hole to control the rate oil feed to the chain.when you push the oil fill cap it puts a slight amount of pressure in the tank pushing oil to the chain and bar.This felt seal gets saturated with oil and evenly distributes oil on the chain.Hope that helps.Good luck.
