My son has a 1961 4010 and the hydraulics seem really slow to me. Also the 3 point seems to jump up and down as it goes up. It seems to steer pretty good and the brakes work good. The hydraulic pump does seem to make some noise, almost a knocking sound. We put on a new rubber flex coupling that drives the front pump but this didn't help it.We capped off the line coming from the front pump and it does have good pressure but the needle fluctuates real fast. We plowed with it and planted soybeans but it seems to lift slow. Also the steering will stop working when you are lifting a plow or planter. We took what looks like the priority valve apart and there is absolutely nothing inside of there but oil. Its just an oil manifold basically. I have been told that the real early 4010s didn't have a priority valve. Is this true?
We want to fix the hydraulics this winter and I am wondering where to start. I think we need to rebuild the front pump. This pump is original as the destroking valve is on the bottom where the newer ones are on the top. Are parts available for this old pump? Also if the transmission pump is bad will it cause the pressure gauge hooked to the front pump to fluctuate real fast like this one does?
