Twraska, I've got a 4640 with jd complete reman engine in it doing the same thing. Took it in to our dealer to listen to it, and they said to run it a hundred hours should come out of it.50 hours in so far and its not much better. Had a couple independent mechanics listen to it and they think its in the pump. Going to be interesting to see if yours or mine gets fixed.
