    had a pump go out pulled hyd tank cleaned metal out of tank pulled control valve had a make up spool locked up replaced valve assy, worked good for about 2 weeks then dlade lift quit and blade tilt is slow. hyd flow goes from blade lift to blade tilt to blade angle. problem sounds like a resolver but I have to work tilt and angle to get blade to lift. where should I start Oh i also replaced the blade lift valve with the old one it worked before makes me think the problen is in another valve
