Hello, I am new to forum and need help trouble shooting hydraulic problem. My 4610 will not drive on right side and i switched relief valve from front to back on right side of front and back pump but no difference I also jacked up right side and cannot rotate wheels. Could my servo vavle be the problem?
Does it load the engine... Yes.... wheel motor... Does it load the engine.. No.... Pump control seized/ rotating group gone
It does everything but drive the right side wheels. Hydraulic tank was low and I was pulling and and tilting it pretty hard. I filled tank and no change.
Not sure about that model specifically but those eaton pumps aren't that great.... The upside to them is you can usually buy a replacement from Gehl for only $2500 (front and back) brand new... which is usually cheaper than repair.... But, wouldn't buy anything until you prove what is wrong
Ok thank you.
Could the servo be bad? Both arms on the side of each pump move.
There is a tow valve on the top of each pump that drives the wheels. It is a round stem sticking straight up with two flats on it, you can use an adjustable wrench to turn this valve and it will allow the wheels to free spin, also they will not be turned by hydraulics when the valve is open. Make sure both of your valves are in the same position if not turn the stem 90 degrees. If this isn't the problem then possibly you have broken a drive chain on that side, and your free spinning the drive motor. You can pull the top or side cover on that gear box and see what is happening. Good luck.
Thank you, I found the problem it was a sheared key on shaft coming out of the pump replaced it all is good.
