Loader la350 loader jerky lift

[carlav1410]

Hello all,
I just finished installing la350 loader on my l2500dt.
Everything works but loader is jerky when I boom up and roll back?
Have rebuilt control valve so I'm not sure what it could be unless its a cylinder
Bypassing ?

Thanks for all the help Carl

Have you cycled the FEL enough to purge all the air?

Check that the QD's are fully coupled.

Is the 3pt lever in neutral? Should not be at the top.

Yes all QD's are coupled and have cycled loader maybe an hr roll back is jerky as well. Dump has enough power to pick front of tractor off ground. I have a box blade on tractor.
I have HP line feeding loader with PB feeding the 3 pt hydraulics along with power steering.

Thanks
