B3000 The bucket stopped lower under pressure IE not gravity as in all the way forward but all i hear is fluid bypassing i think. Just started instantly.. I "ass/u/me'ed" it had dirt debris in QD and nope but it works when i hook both onto the bucket curl side.. So where should i look besides the QD <quick disconnect> I did try hammer tap to the valve already. The "fonz move" failed

Not 100% sure I understand what you are saying but sounds like the FEL down function or the float function is not working properly. But when connecting to the curl connection point it works to have down pressure.

Does the curl cylinders work when connected to the down connection point?

I would suspect the valve or the coupler is defective. If you can eliminate the coupler for that function and test it that would help with the troubleshooting.

 

[OldmanJJ]

Ahh Thank you for reply. If i switch both hoses yes it works i didnt try the bucket curl i just left them disconnected and float works fine just not power down

 

[OldmanJJ]

And more data with the curl bucket it doesnt work when hooked up to buck down up so it appears to be the actual valve as i have also swapped QD tractor side elements so where is the actual valve in that body?

I don’t know for sure what FEL you have.

this is a control valve for a LA403 FEL. The valve is a slide valve and may not be repaired as far as I know.

You may want to check the linkages between the valve and the control stick to make sure they are working properly

Is it cold freezing?

Water (now ICE) in the detents will cause that problem.

 

[OldmanJJ]

No sadly not freezing yet And it appears to be moving correctly It is frustrating because i have the back hoe on now and i hate with a passion removing it to take it in

 

[OldmanJJ]

Checking today to have peace and quiet The side that runs my hoist and lower supply has a small leak And it is sending fluid to the hose not when messy test but i did it... So will a small leak like this cause the loss of power down? Photos to show minor leak and for clarity

 

[North Idaho Wolfman]

No a small leak won't cause a no power situation.
If you swapped the loader lift and curl and you still get no down pressure.
It's pointing to possible cylinder internal seal or piston issue.
