Was operating hoe and was lifting lh support leg when it stopped about half way up. They replaced the pump, filter, fluid and pressure control valve on the block for the hoe. Hydraulics still not preforming. We can operate the tilt on the front in loader back and forth. It still appears the pressure control valve is not working. It is located on the right side of block looking toward cab. Need help.. do any of you have and schematic that will help in trouble shooting? I would appreciate any support. Thanks in advance..
What series is it? 3400,4500,555?
