L3301 / LA525 Float Problem

[DavidLott]

I'm new here. I have searched for an answer. I have read the recent loader valve thread.

my loader was working fine a few days ago. today it will not float. pushing valve into float position stops lowering and loads the engine. All other loader functions work fine.

I have checked all the quick disconnects. I have removed the backhoe from the hydraulics, and tried with 3PH up and down.

Please give me suggestions on what to check.

thanks

Interesting. i dont think we have seen this before. Lets confirm the exact behavior.

This happens when you are lowering the loader normally and push into float before its fully down? At that point lowering stops and engine loads up?
If so does the joystick latch into the float position?

There are a few posts online (not specific to that loader) that say the detent can build up dirt etc. I'd try spraying it with WD-40 or similar.

That's correct Dan. The joystick does not latch. I don't think it ever has.

Thanks for the suggestion. I'm assuming I have to disassemble the valve to spray WD40 in it?
