 my hydraulics quit working

the tractor is a ym240d...it has a loader and box blade on the rear.. the loader started working slower and slower as the power begain to fade it began to jerk and shake as i tryed lifting the bucket, the bucket and soon stoped working all toather.. it had power pushing down but i soon could not rais the bucket at all.. the rear box blade soon lost all power as well.. .. a friend of mine tightend the stop valve located under the seat and held the controls in the down position for aout minuts with the motor running in a effort to self bleed the hydralics...
i belive that was a big mistake!!
the tractor has lost all hydralic power.. i disconected one of the fittings from the ram and tryed to blead it but it had no presure or fluid........
could this be a air leak or air lock??
because the stop valve was tightend with the motor runing did this blow a O-ring or possibly damage the hydraulic pump??
PLEASE HELP

Sounds like your pump was exhibiting death throes, and that your friend's unusual "bleeding" technique may have delivered the coup de grāce

Straycat; Have you checked the fluid level? Sounds to me like you just plain ran it dry. If the loader bucket was jerking while you tried to raise it that tells me the pump is still functioning but just sucking air. I'm afraid your friends bleeding technique with the engine runnuing may have cost you a pump. Put some fluid in it and give it a try. Greg; I don't want to appear too ignorant, bbut what is a Coup De Grace? Frank.

Sounds like it ran out of fluid. And like Greg said, the pump is likely shot due to running dry. You may be able to get a pump rebuild kit which is fairly easy to do yourself.

Sounds to me also like the pump ran dry.

If that was indeed what happened then I also have to agree, the unusual 'bleeding technique' would almost certainly have done some damage to the pump, if not finished it off.

As was mentioned, fill it up and give it a go, you have nothing left to lose now.

Frank, a 'coup de grace' (French for 'mercy shot' and pronounced phonetically as "koo de graw"Wink yeah right is the finishing off of a wounded animal (traditionally with a single close range shot) rather than letting it suffer as it expires slowly. BTW, ignorant would be NOT asking the question. Wink yeah right

Best of luck.

Kthompson; It really wouldn't be quite as much fun around here without having EW around to poke at now and then. He'd be safe anyway, even if I winged him he still could out run me. Frank.
