1986 Kubota L345DT
Hey everyone. How yall doing. I hope good. I need some help. I got 2 problems.
I got a L345DT with a FEL. 1st problem: My FEL and my 3pt lift just stop working. Here's what happen. I let my brother in law use it Monday to level dirt. Tuesday he calls me to tell me the FEL just stopped working. He said he's been using it for a hour or so and put the bucket down to scoop up dirt and the FEL wouldn't go back up. I told him to check hydraulic fluid, it was low. I gave him some to put in it. Still nothing. I went to check for myself and the FEL nor the 3pt lift would work.
This happen before, so I cleaned the hydraulic screen. It wasn't that bad. 2nd problem: Well when I took the bottom plate off. The screen filter fell in the bucket of hydraulic fluid. I fished it out, and I found a rubber washer, not the o ring in the bottom plate, but a washer and I have no idea where it goes. I look at part diagrams but no luck. I stuck it on where I thought it would go but, I might be wrong.
After cleaning the screen, putting back together, and adding fluid, still not working. The FEL doesn't make any sound like it use to.
My next thought is the pump could of went bad, but can a pump go bad just like that, with no signs, warning, or problem, just stop working. Haven't really worked on a tractors all that much. Any help or info would be appreciated. Thanks

It is possible for a pump to fail completely all at once but not common. Check that the three point lever is not against the stop to raise it. If the limit is not adjusted correctly it can allow the fluid to mostly bypass the the loader. If, as you say, the three point is no longer working you may want to check the output pressure of the pump before buying a replacement.

Can you tell if the pump is even turning? If not pull the pump and check drive coupler and pump shaft.

Thanks for the input and info. I haven't had time to check anything yet because of my work schedule. Hope I can check somethings out tomorrow. I've been reading that it could be a relief valve. I'll post again soon has I find something. Thanks again.
