JR,
I just got in from doing the same thing. I found nothing out of the ordinary in regards to the spool. That said, I was checking the main control valve, not travel motors control valves. You can see where it has rubbed in normal operation but nothing you can catch with your fingernail. The bore was also a chore to get a good look at so cannot confidently say if it was worn or had a crack between passages.
Pilot pressure was just where it should be, about 500lbs. In regards to the system relief, i have the correct pressure. For some reason I thought there was a second set of reliefs at the pump.
I’ve yet to measure any pressure at the hoses (mainly because I have no JIS fittings here, or at work) I think that will be the next course of action, tommorow. I will be interested to see what you find in regards to swapping hoses.
I believe I’ve gone down the “garden path” a little bit with this one. I work as a maintenance troubleshooter at a manufacturing facility and it’s an easy thing to do. Oh well.
Maybe the machine just doesn’t perform like I believe it should? Haha. My old Kubota would flip itself over for a joke if you wanted it to.
