Best for owners troubleshooting sluggish or noisy hydraulics on this model.
Posted by the 1ROAD channel, an owner working on his own tractor rather than a dealer or professional mechanic.
A completely clogged screen-type hydraulic filter, which restricted flow and caused the loader to work poorly and the lines to vibrate and make a loud whining sound.
Remove the bubble cap bolts, save the spring and O-ring, pull out the screen filter, drain fluid from multiple ports, install a new genuine Kubota filter and O-ring, then refill with hydraulic fluid.
The owner tried cleaning it with diesel and a wire brush but gunk remained inside, so he ordered a new genuine Kubota filter for about 23 dollars instead.
The owner changed it because although only about 15 hours had passed since the last change, a long time had elapsed, so he changed the oil and filter anyway.
