Bucket Curl

[RingpowerCharlie]

i have a 336f excavator have checked valves lines etc and i cannot seem to figure out why my bucket wants to continue to curl slowly after i let go of the joystick i have looked into the bucket spool relief valves have swapped lines to see if it reverses the effect but it still curled in if anyone can help me i would greatly appreciate it

Here’s good literature to follow to help diagnose your problem. Machine serial number could also be helpful for further diagnosis.
