    Case 580C Clutch Switch Loacation

    Thanks for the info. I have the manual shuttle, so the floor and dash switches are not there. Looking for the starter cut out switch. The one pic might be it, but I can't seem to find that in the parts book. I see the 2 brake switches, but not the clutch. This photo you posted looks close...

    Case 580C Clutch Switch Loacation

    Can someone post a picture of where the clutch cut out switch is located on a 580C? I have a bit of a project machine, and the switch is missing and I don't see where it should mount. I see it in the electrical diagrams, but can't find a mounting bracket for it.

    1996 JLG 45HA repair questions

    That is one rusty machine. I wish mine was 4x4, but I've managed to get by without it. When I set my drive pressure, I think I set it a bit on the high side of 3k, just to make sure. They don't have a lot of power in the high speed mode, but when it gets moving it seems like you are doing...

    1996 JLG 45HA repair questions

    I don't see why your gear or hub should not come off. You can try to put the hyd motor back on the basket and see if that will break the gear loose. The gear should spin on the shaft, and the clutch pressure moves the basket. Unless this went bad at sometime and somebody did a repair so the...

    1996 JLG 45HA repair questions

    I used this controller to replace my drive controller. No issues so far, works better now. https://www.ebay.com/itm/JLG-Joystick-Controller-1600141-New-w-1-Year-Warranty-FAST-SHIPPING/172864129480?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649

    JLG 40H - boom swing does not move in creep mode

    I hear ya. I started looking at 40's and ended up with a 45. I could really use a 60 but was trying to kèep the weight and machine size down. I'm working on a slate roof so it is really needed especially if you are the one man show.

    JLG 40H - boom swing does not move in creep mode

    If you were working on the wiring on the platform controls, than I would check the wires/connector going to the swing controller. The creep switch sends a signal ( I think 12v) to each controller telling ii that it is in creep mode. Maybe a bad connection at that controller.

    JLG 40H Telescope in,steering and basket rotate/tilt stop working

    I would take a look at the wiring. This sounds like a possible grounding issue with the function valves. I don't know if all these functions are related wiring wise, but they could share a common ground. I had a similar issue where I lost the ground to one side of the solenoid bank, and I...

    JLG 40H - boom swing does not move in creep mode

    I would check the pressure when you actuate the valve. If it works in not creep mode, than the valve is probably ok, but you need to test the pressure based on the test procedure in the manual to make sure the pressure relief is set right. Once you know that is good, I would look at the...

    JLG 120HX drive issue

    I would look at the counter balance valve that controls the brakes. If the engine is loading, than you are probably getting pressure, so I would first find the pressure test quick disconnect and put a gauge on it. You should see probably 3000psi when the drive valve is functioned first to...

    JLG 600A main tower not dropping

    You don't need to remove the AL block valve body. Just remove the plunger like you did. I put ne O-rings on mine since it was leaking. It needs to move freely. Hopefully that fixed it.

    JLG 40HA basket won't rotate

    I have a 45HA, and there is a 1/4" x 1" roll pin in the worm gear on the basket rotate gears. If the worm gear and large gear are turning, than you need to look at the basket brake. They call it a brake, but I think it is more of a slip clutch. The gear is not fixed to the shaft. There is a...

    JLG 600A main tower not dropping

    And I forgot to mention it is adjustable.

    JLG 600A main tower not dropping

    Mine has a sequence valve for the tower lifts. One of the tower lift/extend has to be raised all the way before the other. Same as going down. Mine are hydraulic push button type limit valves. I did see in the manual, some versions have electrical switches. One of mine was leaking, and I...

    JLG 600A sputters and dies when hot - Gas Carburated

    Good news. Maybe fuel pump or line issue. Mine does the same when the fuel is low. Once the pump is primed it starts up, but if it sits for awhile with a lower tank level, it won't start. Not sure if there is a filter in the tank or not that may be clogged. I need to look at one day.

    JLG 600A sputters and dies when hot - Gas Carburated

    You could have a limit switch not working right if it doesn't get out of jog mode. Probably not related to starting, but maybe causing the delay in your bucket swing. Maybe jog mode adds the delay.

    600A Platform Swing not swinging

    I guess you need to verify that it is or isn't programmable. Sometimes these functions have lockout valves so they don't move if you loose a line, maybe that is not working and the fluid is draining back. Maybe the fluid id draining out of the line thru the valve spool. After it operates...

    600A Platform Swing not swinging

    The service manual for the 600A shows the analyzer like the other guy says and does not have those pages in it. What year is your machine?
