Problem with Kubota LA724 Loader

[SteveCornell]

This evening I was rooting out some brush with my grapple when something went "POP" in my loader, now I do not have any curl power, I can curl down and I have power and it holds but when I curl back all goes limp and I have no power back.
I think I damaged something in the cylinders, any ideas ???

Curl cylinder is retracting on curl backward!!

Bucket curl forward!!

Does bucket move anything on curl backward??

If NO for backward, piston most likely came off the piston rod inside one of the the cylinders....."POP".....

Yes, that is what I suspect, I can lift the front of the tractor off the ground and the valving will hold it in place (extending cylinders out) but there is nothing when I try to retract the cylinders...... Sound like I broke both piston rod ends..... I'll have to remove the cylinders and get them rebuilt

one piston off is enough to disable both...they are plumbed parallel... if you have a couple plugs for the hoses you can determine which cylinder is bad....OK? do that before starting dismantle the "whole" machine....unhook the hoses on one cyl..,.and check if FEL runs "normal" with the other cylinder....
