Steers like a BARGE!

Yesterday all was well. Tonight, no power steering. All Fluids full. No major or new leaks. Any ideas??? KAMA TS 254

Does it steer at all? Is it a 1 or 2 pump tractor? I am assuming its a 1 pump tractor. If so does everything else work like the FEL and 3 point? If yes, its probably the steering cylinder. You may take a look at the priority valve but I doubt its it. I know the steering cylinder seals are a common item on the Jinma line but not sure on the Kama. Its a easy fix and for the Jinma and the parts are readily available and only $25 or so.

When's the last time you changed the filter?

Does it steer witht he front end jacked up.. but not steer with it on the ground?

if it uses a DA cyl on the front for steering, jack up the front steer over to lock on one side.. remove the 'exhaust' line and leave the pressure line hooked and continue steering against lock.. oil will exit the exhaust port on the cyl if the packing is bypassing.. if this is happening.. you will have -0- effective power steering.

post back more info

Are the remote levers in neutral ?

Keep it simple guys. It has two pumps, two sumps (both filtered) no remotes. In short, steering hydraulics are completely independent of main hydraulics. It's not a conventionally anchored DA cylinder either, there is no drag link. The TS steering cylinder is a smaller (but imbedded) version of the one in the photo.

Besides the filter that greg mentioned. the other possibility is the PR valve built into the pump is stuck open. did it quit just after turning hard to stop? We have not seen it on the KAMA but since the engine is the same as the Jinmas, and the ps pump has the same drive as the main pump on the 200 series Jinma, it could be the tang on the pump, or the slot in the drive has worn and stopped turning the pump... If you can still make the wheels turn by heavy effort on the wheel, the "steering motor" or control valve is probably OK. Blown seal in the cylinder will usually affect holding position, but not the power steering effect itself.

my test shold still works and apply 100%.. it is still a DA funcion cyl.. even if it has exposed rod at both ends.. it will still have 2 lines running to it... and one will be return,and one will be pressure, in a given steering direction.. if it is internally bypassing the internal seals and packing.. it should be obvious with flow across the cyl packing and out the other side.

Ok Chris. But you're shooting blind. Note I used the term "imbedded" when describing the cylinder. Your "test" could in some cases require partial disassembly of the front end. There's some easier stuff to check before digging in that deep.

Like I said, let's keep it simple to start. When the OP answers a few tractor-specific questions, those of us who actually OWN (or sell) the TS-series can and will move on to the more in-depth troubleshooting - including how/where to disconnect the cylinder lines.

Chip, It still steers with a lot of effort, but it feels like it is trying to "unsteer" itself.
