Hydraulic haywire 2

[jwcinpk]

Well after getting the tractor back last week and thinking everything was gonna be okay the hydraulics are crazy again. Stuck in the up position! Talked to the mechanic at the dealer today and he said it's because the lever has been pushed too far down and that puts too much stress on the pump. The major problem with that theory is the hydraulics have not been used since I got it back. There hasn't been an implement back there. Has anyone else been told that if the lever makes it's way past the stop it will ruin the pump? I am beginning to tire of excuses and want to get to the bottom of what could be the real problem causing this. I made sure the lever could not go past the stop by putting a bolt and nut there to block the lever from entering those positions. Could there be something in the fluid? I was told they replaced a piston and a sleeve a week or so back. I am absolutely pulling my hair out with this.
Perhaps some of the other Mahindra dealers who frequent could help diagnose the problem.

As well as I remember, the operator's manual specifically said don't force the lever above or below the settings on the quadrant. I have the the Service Manual as well, so I may have seen it there--But I did see it somewhere....BobG in VA

I can buy that the stop is there for a reason and that the lever shouldn't be pushed past it and maybe inadvertently it did get pushed past it before, but this time there is no way. There has got to be another reason.
It made it a week this time without even putting a implement back there. I raised the lift arms so they wouldn't be running into the dirt when I backed up where I was doing some moving dirt and they started squealing and trying to raise even further again.
