I don't have the FEL s/n, so would have to find that out for you. I no longer have the tractor; it's now my daughter's and has been transported out of state. I do have the tractor s/n, if that should help. I can tell you that when I went to JD dealer to buy the seal kits, I gave him the p/n that I bought from them when I rebuilt the first 2 cylinders, a couple years ago. He looked that number up and told me that it has been replaced with this number. The seal kits were similar, but one of the seals was a different color. In any case, the new kit worked.
My tractor s/n LV4100 114115***, if that helps.
