Hello and good morning, I have some hydraulic problems with my Ford 800 backhoe tractor. I believe that it is a 1953 model and it was all factory equipment until. I know there's the problem "until " a few years ago the hydraulic control valve for the front end loader was leaking internally and externally I replaced all the seals in it and it quit leaking externally and dripping on my boots, but the cylinders started to leak down and didn't seem to have the lifting power anymore. So I did some searching for a replacement control valve of the same valve that came on it originally, I did find used ones for like $250 and there wasn't any idea if they were wore out or worse than mine. So I started looking at aftermarket control valves (obviously overseas brands) so I originally planned on going with a 2 spool valve design that came on the tractor, but then I started thinking to myself hey if I have to refabricate some of my tractor to accommodate the new valve why don't I go with a 3 spool valve ( in case I ever needed to add something later). So I did just that and it worked perfectly solved leak down problem and no more oil soaked boots. A few months go by and I decided to build a grapple for my bucket, I start by watching some YouTube videos and different ideas on the subject and I come up with a plan and I built it ( I'm gonna try to upload some pictures) and I'm sorry about the long winded post, but I figure with the whole story maybe someone can help me with my problem? So I built it and I worked way better than I ever thought it would, but as used the grapple more and more I noticed that the hydraulics to the grapple cylinder really started to bog the engine down making it labor a lot. The rest of the cylinders on the front end loader worked normal just as they always have. So when I would use the grapple I would only open the valve enough for it to operate without killing the tractor, but I know that something isn't right with it. A few days go by and a good friend of mine offered to cut down some trees that were leaning over my storage shed while I was at work ( now keep in mind he helped me rebuild this tractor and I don't consider him a dummy) of course I told him to go ahead and use the tractor. He calls me and said that he started the tractor and the pump split (cracked) the housing, he never even moved the tractor and this happened. What could have caused this to happen?
