Sorry I first posted this dilema in attachments, but it seems better suited here in hydraulics. Here's the story. New Millonzi ld 66 grapple arrives and the front disconnects are EXTREMELY tough to connect. There was no quick. In fact no way one person could have pulled the female sleave back and put male hose in. Should it be this hard..? Do people mount the connectors on to the FEL crossbar so they can get leverage pushing sleave while fitting in male end. I know now that I need to stop engine with FEL raised and grapple open full to bleed pressure from the hoses but the sleave itself is still tough to push back. Is there a difference in parts..? Did dealer give me "cheaper
quick disconnects..? Should I disconnect rear remotes and connect front lines
first. What am I missing ? Also the grapple has caused the curl valve at the
main hydraulic female/male connection to pop out 3 times. Is there a bleed
value that needs to be tightened..? I have pulled on the noses hard and I
know the connection was tight and then gone to the burn pile shaken the grapple/curl function while dumping materials and low and behold there goes the curl. I look down and sure enough the line has popped from the female fixed valve at the main group of FEL hydraulic stations. Is this valve meant to blow out before the line does on heavy work, which I wasn't even doing. I did pick up heavy duty plastic culverts with no trouble, but that was straight in lift and light curl to tighten. What am I missing on just this line ..?
