Useful for owners troubleshooting drooping loader attachments before deciding what to rebuild.
Posted by the Short Line Parts, LLC channel, presented as a hands-on troubleshooting demonstration rather than a sales pitch.
Switch the lift hoses with the bucket hoses at the valve, then raise the loader and tilt the bucket and wait several hours. If the droop stays with the bucket, the cylinders are leaking; if it moves to the loader, the valve is leaking.
There is likely an internal leak in either the bucket cylinders or the control valve, even though no external leakage is visible on the hoses, couplers, or valve itself.
Relieve hydraulic pressure first by starting the tractor, lowering everything, shutting it off, and operating the joystick a few times to release remaining pressure.
