Have a Linkbelt 8640 crane, all four outriggers where out for job. Now they will not retract. Thinking the 4 way directional cylinoid valve could be the problem. Has anyone had this happen? Thanks!
We got them to extend, not for sure how!! I reversed wiring to the the four way directional valve and got them to retract so we could bring it back to our shop to work on it! We have been stumped at this ordeal haha....definitely an electrical problem! The upside to this, we had lifts at the job sit all this week so that was a plus!Ever get outriggers to working??
I was referring to the retract and extend valve as the four way directional. We have good voltage on all the switches and solenoids. We do have fender controls and upper cab, checked voltage and its good. Cleaned all grounds on outrigger boxes and main frame also.I don't know what you are talking about with "four way directional valve". Typical system has extend or retract for flow, then separate solenoids for individual cylinders. Front left jack, front left beam, etc.
So when you hit switches, you have the choice of extend or retract, and then you choose which cylinder does that. So there is one two way directional valve, that is either extend or retract, and then all the cylinders.
I'm assuming that you simply swapped wires on the directional, which means that you simply have a lack of power coming from the retract switch side.
Do you have the fender control panels as well as the upper cab pendant? Its easiest to check voltage at the switches on the fenders, and see if you have the correct voltage there, and then you can work toward the upper or toward the directional valve, depending if the fender controls are working correctly.
