VerifiedHeavyEquipmentTech :
Hi my name is***** will try to help. It is very possible that you have some metal stuffed in your control valve and relief valve on that circuit. Remove and inspect the valves for metal/debris/ and damaged o rings that could cause them to stick or bypass pressure. Also, you can check and verify your pressure to the drive motor with a test guage. If your pressure and flow is good than you could have a bad drive motor. You can verify this by running the case drain line from your drive motor into a bucket and engaging the lever for travel with the machine secure against a solid structure so it will not move. You should have a low volume of oil from the case drain. If it is high volume or under high pressure than your drive motor is bad. I hope this helps. Let me know if you need more help with this
JACUSTOMER-8vpumcsp- :
Are the control and relief valve one item or two? Where exactly are they located? Please the corresponding John Deere diagram so we can located this item. With regards ***** ***** the pressure, the skid steer cannot be moved and is not secure against a structure, so I don't think we can test the pressure. Is it safe to assume that if we check the valve(s) you mentioned and there is no problem, then it must be the drive motor?
JACUSTOMER-8vpumcsp- :
Sorry for the typos: I'm asking for the diagram from JOhn Deere which shows the valve or valves you mentioned.
JACUSTOMER-8vpumcsp- :
I keep getting email to rate your service, but I cannot without the further info already requested.
