So, about two months back I had contaminated hyd oil and screen in my 4630 QR, and a PTO lever that wouldn't stay engaged with poor hyd pressure. Didn't have time to break it open, so took it to the local mechanic (not the deere dealer) that I have had good luck with-
He put in a new high flow trans pump (only one available from deere at this time, took off the cover for the pto valving and said the little lever inside was broke as many of you suggested it was- They inspected from the top with the rockshaft cover off and could see or feel nothing else wrong with the trans.
I asked them where the heck all the brass flakes came from in the screen, and if it was the brakes. they said they pulled one wheel and the brakes were brand new, and saw no reason to pull the the other side.
They suspected the hyd pump, but said it looked like it had just been rebuilt or replaced judging by how good the teflon washers on the large plugs looked.
So after all that, we didn't find the culprit of the brass flakes. They told me to use it, and I have been for a good couple weeks now, I've been meaning to drop the oil again and check, but haven't had time to yet. hopefully in the next couple days.
My main question is, they tell me the only sources for brass flakes would be brakes, and hyd pump. Is this true?
The HYD system seems to be working well now except for a vibration in the hydraulics that I can feel in the steering wheel and in the tractor at certain mid rpms, but they are working.
What would you do going forward? I plan on dropping the oil soon and will let you know what I find on the screen.
