My 5519 telehandler has a leaking safety valve. I don’t know much about them so I took it apart and broke the nipple off the top so two questions here. Why would oil be coming out the top of the valve and can you buy just the part I broke off? I can’t find it in the parts book. You have to buy the whole valve at $800+. I’m thinking about having a buddy try to weld it back on as it’s not under pressure it’s just a relief port.
