Hydraulic Loader Weak

joe1383 · Jan 26, 2023

I have a Freeman 3000 front loader on a 1959 Ford Workmaster 601. I purchased this setup about 2 years ago. The hydraulics were nice and strong. This spring I noticed it would take forever to lift the bucket. I checked the fluid and noticed it looked like chocolate milk. I emptied the old fluid and cleansed the system with diesel fuel at the recommendation of a local shop. This changed nothing. I see no apparent leaks anywhere and the fluid level has not changed. Any suggestions? I do not know a whole lot about hydraulics and rely upon google searches for my knowledge, but have more confidence from the people on this forum than google!

Time to put a pressure gauge in the system and see what pressure the pump is putting out.

Is there a filter on the system?

Is there perhaps a suction screen or filter ahead of the pump that might need to be cleaned or replaced?

If NOT, likely the pump is worn and not working as well as it once did.

Relief valve could be stuck or spring broken

Reseal the cylinders. Piston seals worn out.

(quoted from post at 10:42:47 01/26/23) Reseal the cylinders. Piston seals worn out.

The O.P. doesn't mention the loader dropping once it's up, just that it raises slowly.

If cylinder seals are worn out loader would drop once raised to any level off of the ground.

Old.
Isn't that an OLD man's problem, a weak pump?
I put a pressure gauge on my Jubilee.
Only shows pressure when I'm lifting something.
The pressure depends on how much weight I'm lifting.
My pump was weak because one spring was broken inside the pump.
If you have a weak pump get closer to the urnina or you will get your feet wet. lol

George, I think the pump pressure would show when you fully extended the cylinders and cracked the relief valve.

Yes once the cylinder hit the end of travel you get pump pressure/relief valve pressure

o Filter that I can find. A hose comes out of the bottom of the mount (which also serves as the tank) goes into the pump. From pump to controls where it is split two 3 cylinders (2 lift, 1 tilt).

Sorry I did not note, it does drop to the ground over a period of time. When you shut the tractor off and the bucket is up you can hear it click and eventually it will be on the ground.

Also after holding the control down for a long period of time and have the engine rpms high, if I try to drop the bucket hydraulic fluid does shoot out the dip stick. This model has the long tank behind the controls with a vented cap and a long threaded dip stick in the middle to check fluid level.

what about the hyd. filter??? did you change that?

joe1383 · Jan 26, 2023

I can not find one for this front loader.

Check to be SURE there isn't a screen that extends inside the ''reservoir'' attached to the tank outlet fitting.

While your specific loader may not have one, it IS a possibility.

after you updated that the loader leaks down while sitting and it sounds like it does this quickly. leaking past the cylinder and probably leaking at the
control valve are both issues that you need to fix, after those are fixed you might still have some other issues with the pump. this tractor is over 60 years
old and it can not be expected to operate as new. good luck

You can make your own hydraulic pressure test gauge with a simple 3000PSI liquid filled pressure gauge, a Pioneer coupler (or one compatible with your tractor) and the plumbing fittings to connect the two together. Total investment <$50.

the filter would belong to the tractor hydraulic's not the loader.

Geo can you explain the Kroger fuel point reward system. I have 219 point right now but have never figured out how to redeem them
