Loader JD 1250 weak loader. Help needed

[chrisp223]

I'm having a problem with my front end loader. When I lift the bucket the hydrolyics sputters and jerk. I have replaced all hydrolytic filters and got a new hydrolytic pump put in and have rebuilt the cylinders on the bucket. Would appreciate any help.

When you say "lift the bucket", you are speaking of raising the arms of the FEL, and not curling the bucket?

Was this "sputter and jerk" the same problem before hydraulic filter, pump, and rebuilt cylinders that is continuing? or has started after the fixes?

Have you checked:
Oil level?
Quick couplers properly connected?
Could Quick couplers be cross connected?

Try swapping boom hoses with bucket hoses to see if the valve is worn/internally leaking.

It happens when I lift and curl and the problem was what sparked the repairs but even with all the new parts I am still having the problem.

What can you tell us about the history of the tractor and FEL. Age, hours, ownership, etc.

I will check those thank you.

Possible hyd relief valve not set to spec's. Check hyd pressure with a gauge.
