Hey guys, I have a Hyundai 210 LC-3 with slow hydraulics. Filters are new, screen is clean, she's not too bad first thing but quickly slows down as she warms up. I figure the pumps are finished, especially since they've developed some external weepage, but when I check the pressure off them (cold and hot) they both meet idle and relief specs given in my shop manual. Is it possible for bad pumps to meet spec??
