Well I have read every forum thread known to mankind and still cannot sort this mystery out. I have a case 580c hoe with steering issues. Power steering rarely works. When it does, it works great but rarely does it work. When front bucket is empty steering works to some degree (can spin steering wheel and get wheels to turn) but as soon as I scoop up something forget it. I lose any power steering assist (steering wheel cannot be turned). I have replaced the pump, both steering cylinders, filter, all new fluid, steering body (on the steering shaft below steering wheel) with all newly purchased items... not used parts! Since it does work on occasion, it seems the parts actually do work when they work. I was thinking a valve ball stuck somewhere that frees itself up on occasion, but after replacing all parts with new parts nothing has changed. What the heck is left in that system that could be at fault? I suppose maybe I got a bad pump. I do not have a way to check for pressure out of the pump. Any thoughts guys and gals?
