Anyone know why my Case 1030D has no lifting power to the plow cylinder.

It will move in the freeplay to the stops but will not lift the plow.

The lever will not stick in up or down, I have to hold the lever for and aft.

Fluid is ok.

Something stuck open or closed?

There are two places that could be the problem. Your pump could be wore out or you could have a problem with the relief valve. You need a flowmeter to check the pump flow under pressure to decide which is bad. If it works a little better cold than warm then I would lean toward the pump being the problem. The relief valve is under a large cap on the bottom of the remote valve body. It takes a 1 1/4 wrench. The valve body has to be removed from the tractor. The fuel take has to raised up or removed to get the valve off. You might find a blown o'ring or you might have to replace the whole relief valve. Stan

Stan,
I have a parts catalog but it doesnt show where the pump is located. Is the pump located up in the same housing near the relief valve and control valves.

There is a big steel hyd. line coming out of the pump right above your third link. That is your pump. it is easy to change but is pricey. Stan

Stan,

Thanks for the help.

I tried to half an aluminum pump for my 300U ground and oversize gears installed but it was wore to much. Cost 700 for a new one.

Thanks again, Dell

rockshaft(3.)works fine.

The remote shaft works only with no load.

It will not raise the plow.
