No lift power

[goblerblaster]

Let me clarify. With the 3 point lift lever in full up position, the FEL will barely move, meaning won't go up, down, dump or curl. If I drop the 3 point down just a little, then every function on the FEL does what it is supposed to. BUT recently the FEL loader has lost power to pick up much weight no matter where the 3 point lift lever is. With no weight or little weight in the FEL- and the 3 point not fully in the highest lift position-the FEL loader does every function up, down, curl, dump. If I put 200 pounds in the FEL- then the won't pick it up. Example= I have the FEL loader bucket about 2 feet off the ground and load four 50 pound bags of seed in the bucket- now the FEL will not lift any higher. It will go down and try to curl and dump, but it will not lift any higher..

If I get a scoop of gravel in the bucket, the FEL will not lift it off the ground at all. Before the loss of power I could scoop a bucket full of gravel with no problem UNLESS the 3 point lift was in its fully up position. Thanks for your response.

Are you sure that is accurate. The loader should still dump and curl

In any event time for a pressure test:

1. Start the tractor and bring it up to operating temperature.
2. Shut it off, remove the hose on the P port of the hydraulic outlet block, and connect a 3000 PSI gauge in its place.
3. Start the tractor and measure pressure at 2800 RPM. It should be roughly 2200 PSI.

Thanks for all the help. I have decided just to take it to the Kubota dealer and get it fixed.

Kubota dealer did some tests and told me the hydraulic pump is bad. THey want $1450 plus tax plus labor to put one on. I think I will do that myself !!

I think I would spend $50 to test pump pressure myself before opening my wallet that wide.

Well, I wish I would have.. I bought a hydro pump, put it on myself and the end result is that it is still the same. Kubota charged me $268 to tell me the hydro pump was bad, so I got an aftermarket n put it on, bled the lines etc and it still want pick up hardly any weight. At least I didnt pay them $2500 to replace it and the there would be more coming sice that did not fix the problem. I am thinking I should remove all the lift cylinder lines and blow them out and try again. There is fluid coming out when I bled them- but just no lift power. If I put the bucket on the ground it will pick the front of the tractor off the ground.

Any suggestions will be appreciated

I hate to say it but I am not surprised by that outcome.

My suggestion is the same as before.

1. Quit guessing and shooting in the dark. Dont waste your time blowing out lines. Thats not your problem.
2. Get a 3000 PSI pressure gauge and start doing some targeted testing. You will find the problem in short order.

Apparently your dealer lacks that expertise.

Just to finish this thread,,, the part 090 on the Outlet block diagram on a Kubota l2501 was put in upside down. Once I reversed that the tractor seems to be functioning as indented. Thx to all that gave me advise and commented . I think after nearly $500 all I needed to do was reverse that one piece.. Live and learn

Your tractor was working initially. Who put that poppet in upside down and when?
