Ford 1900 Hydraulic Help

[CACameron]

Hello,

Let me say I know little about hydraulics, so I am looking for help in diagnosing a problem I am having with my 86 Ford 1900. The issue is the loader has little lifting power. I can load the bucket when raised with dirt by shovel and it holds the load. There is a slow drop in the bucket 10 min. I cant raise the same load though. As well the three point dips whenever I raise the loader loaded or not. I replaced the hydraulic fluid and controls already with no effect.

Thanks,

Chris

A lack of lifting power can be caused by a dirty or clogged filter or screen in the tractor's hydraulic system. You'll need to check the tractor manual to learn where such a filter or screen may be. There is an allowable rate specified for how fast the bucket may drop on its own. If it's dropping faster than that you may have an internally leaky hydraulic ram.

Chris, I know about as much as you and the same kind of thing happened to mine. It was real slow to lift, I don't recall if I saw anything happening with the 3 point at that time but I decided to try and clean the filter/screen. For me it did the trick the screen was really jammed up with a lot of debris. I pulled it out and gave it a nice wash/cleaning with diesel fuel and put it back in and everything seemed to be back to normal good lifting power on the front loader and 3 point was fine. I could lift a harlel rake which really pushed the 3 point limits. It was kind of expensive because I did the same thing you did just change the fluid at first and when that did not help I decided to do it again and I just burned up all that fluid and got new. Make sure you put the right fluid in too mine called for the 134 fluid. Tractor supply sells some premium stuff that says compatible with new holland 134d and thats what I used. It was about $45 for 5 gallons and I got a 2 gallon one as well. let me with about a gallon spare.

Thanks for the input. When I changed the fluid I pulled what I thought was the filter. Awkward location. The cylinder that came out was not what I would have thought would be a filter, having 1/8" holes in it. I assume I must have just removed a part of the filter??

From looking at the parts diagram this is where the filter is located.

Yes that is the cylinder that I pulled out that had the holes, no mesh.

I do not know your model of tractor so am running a bit blind.

I assume you removed the bolted flange and gasket and not just the banjo bolt.

It does not make sense for a hydraulic filter to have 1/8" holes to filter the oil.

I am wondering if what you have pulled out is the guts of a filter where the fine filtering part was around the outside of what you removed.

I found this photo which may be of a filter for your tractor.

I'm thinking I did exactly that. I'll have to pull it again and pay closer attention. Thanks!

Chris, the picture Dave sent is the Ford 1900 hydraulic I just replaced mine yesterday with exactly what is pictured. It is in kind of odd location towards the middle of the transmission housing is that where yours was located? That mesh is super fine underneath it I could see the 1/8" holes you were talking about the mesh should be over top of them. The oil would go through the mesh, through the 1/8" holes then out that hole in the flange where the pipe should be threaded on with a big hollow bolt with holes in it. If you are missing that mesh then you probably have a clog somewhere. I can't imagine that mesh coming off. On my model 1900 there are 2 drain plugs to get the hydraulic fluid all out. I did not see the second plug the first time I drained my hydraulic fluid and when I took that filter out about 3 gallons of hydraulic fluid came gushing out ha. This time I really looked around and eventually found the hard to get to second plug. Here is a ford 1700 it is similiar set up for the hydraulic filter at about 0:54 he starts to show where the pipe is at the front and goes to the back to the filter How To Change The Hydraulic Fluid On An Old Ford Tractor - YouTube Is this what you see?

Yep that is exactly what I pulled and checked. I hope the screen isn't somewhere in there mucking things up.
