QuestionQUESTION: hi i have friend who has a ford 7610 with a hydraulic motor run beet feeder that requires over 2300 psi or it will not work properly the tractor has a main pump and an auxilary pump both feeding spool valves
i was given a tool to test the presure straight out of the main pump and i got 2500 psi then with the main pump disconected i tested the presure from the spool valves and got 2300 psi
my problem is that when i connect the main pump back up i only get 2000 psi is it a priority valve problem
do you know where the pressure reliefe valves are on this tractor
ANSWER: This is a question that had me thinking, as I don't know about this peticular model but need to ask you some questions. First off you say that the beet feeder needs 2300 psi to work properly?
If the spool valves are running Orbital motors then we need to take gallons per minute it to account. If the pump is not putting out proper flow then pressure is going to be relative. The pressure relief valve is on the cover of pump and is a replace unit. The priority valve is on the rockshaft housing. I would like to know a little about how the beet feeder works so I might be able to help more. If it is a pressure thing then you could have either a relief valve or priority valve problem but your guess is as good as mine.

QUESTION: the beet feeder looks like a big grain bucket with an auger inside and a chopping blade at one end it is driven by an orbital pump as you guessed it is filled with beet and the auger brings the beet to the blade gets chopped and fed out the side to cattle
now i don't think its a flow problem as it runs at a low speed and the pumps run the front loader nice and fast
another friend of mine reminded me of something i had forgotten that ford quick couplers can be of a slightly different length and when back pressure comes on the opening at the nipple can be so small that the pressure could close the nipple. i have come across this problem before with tipping trailers but that was 15 years ago and i was lead to believe that new male couplings will fit fords and every other but i will check it out do you know if universal male 1/2 inch couplers will do these older tractors or do you need a specific one for fords either way i will find out and let you know. i hope this made sense the couplers on it are new but could be of a slightly different dimension? well worth a try
AnswerIf it runs at low speed then does it kick out at high speed? If that is what it is doing then yeah it could be your couplers. Stick with pioneer and you should not have any problems with back pressure. If it still runs slow at high rpm then it is a flow problem. Or a pump suction problem such as a plugged screen or filter. good luck
