Hello everyone, I have a 1997 jd 310se with loader control problem The loader bucket does not curl upward when you try and pull loader control arm towards your right leg. You can actually bend the linkage if you pull hard enough. I had lubricated all the linkage last year and I thought it was better. I haven’t used it in a while and when I tried it it was so stiff it bent linkage. I’m not sure but I think the problem is in control valve. I have never been inside one of these so any ideas would be appreciated. Thanks,
Welcome to HEF George ! Let's isolate the issue to either the control valve or the linkage. Disconnect the linkage from the control valve spool. Is the linkage still stiff?
