6410 John Deere Hydraulic Problem

[Anonymous-0]

I have yet another question about a hydraulic problem on my JD 6410. I have had problems out of the new pump where the stall out pressure would not exceed about 2000 psi. I found that I had a bad O-ring in the loader valve of the valve stack which was throwing my sensing off. Got that fixed and now the pressures are correct. The problem now is that when I stall the system out at max pressure then release the SCV or whatever, the pressure slowly drops back down to the 450-500 psi standby range. I don't believe I had this problem before I replaced the O-ring, but I am not 100% certain. I really don't know what should be checked next. Any help would be greatly appreciated.

Don't know what previous problems you have had, but I think there are a couple of factory solutions related to this complaint. You'll need to see your dealer. They will need to know exactly what you have before they can offer any suggestions.

With all the various gadget options and vendor updates, {factory AND aftermarket} I sometimes have trouble seeing two tractors built alike.

I have it at the dealer now and they are having trouble locating the problem too.
