The JLG 40F Boom Lift Dilemma

[Trolleyman]

I just sent 7 pictures and the serial number over to Dewayne. I mentioned your name. He sounded like he wants to help.

Where did you find the serial number I can't seem to locate one on my 40 f

Does anyone know a supplier to get a replacement Racine drive solenoid? The wire has broken off at the body so there is no way to splice it.

check this out, it sounds like you need the same piece. It's a coil.

Thanks! I found a supplier and have one on order.

Soon as I figure out how to scan a 17 x 22 sheet of paper :beatsme

Please I need these drawings aswell

What supplier

 

[Scooter.crew]

GCIRON out of Hollywood, FL. Part wasn't cheap with shipping, but it worked and was the only place I could find it.

Please I need these drawings aswell

What drawings are you looking for? Wiring Schematic? Racine or Bertea valves? type of controllers?

do you have the 40F manuals yet?

The cylinder that lifts the main boom is leaking bad. Time for a rebuild. All hoses and top pin are removed. The bottom pin is not cooperating, got it to move about an inch and it stopped. Wow, so close and so far away. Is there something I am missing here?

 

[OFF]

Do know what I mean when I say the lift cylinder's lower pin is secured by something that looks like a main bearing cap on an engine block?
It is. The nuts are under the chassis, 4 of them. have you undone those nuts? pounded the bolts up with a dead-blow hammer to loosen the caps?

 

[dn29626]

I will look for those 4.
The cotter pins at each end of the main pin easily removed.
Thank you OFF.

Does anyone have a parts schematic for the racine proportional valve solenoid like I have in the picture for a 40F? Wondering if I'm missing any parts. Have a parts break down for a 40h that is different from what i have pictured . Put a manual valve on to test. Functions worked with another valve and able to verify that have good pressure . Pushing in the solenoid by pass pin does nothing. Have completely gone thru several times. Did find missing push pin (made one out of a drill bit) Was missing small spring and spring poppet installed backward by previous owner all in the same section. Took the solenoid to electric repair shop. they say solenoid is good. Took the valve to a hydraulic repair place where it sat for two months before they admitted to not having a clue how to test.
This leaves me with more questions than Oak Island. The questions I do have are,

1. Are any parts missing in the picture of solenoid parts?
2. Which way does the pin circled in red go in, narrow side toward the valve or wide side?
3. Is there any places anyone knows of to have them check this valve out?
4. Anyone have a lead on a working used valve?
5. If anyone has replaced this valve with another brand would love to hear from you as to how you did it and what you did for controlling the valve.

The picture you put up is what I would call a Racine Dump Valve.

 

[OFF]

Here's the part numbers to go with the diagram you posted.
I don't see a spring in yours - ref. #20
I don't see a ball - ref. #26

If that picture of the valve I posted is the same as the one you're working on, I have a new one.

This is a solenoid valve, but the parts are quite similar. Might help

Hello, I have a JLG 60g with Racine valves and PQ controllers. I am attaching two pictures of the one controller I have still functional and a new circuit board I received. The older board gives my 6 volt output off center. The new one appears to be a little different and does not give me 6v off center, it goes right to full voltage. Can anyone identify the possible model number of the older circuit board in hopes I can locate two of them?

Thank you!

 

[OFF]

Here's what the card should look like.

What part number did you purchase? The newer boards for the "H" series are #7003737 and I believe they are a different voltage on the coils.

Double check your wiring, make sure it's hooked up right.

I purchased part #7003706. I found my wiring from the control box on the basket to the machine had wires spliced and soldered and I just received my new roll of wire to rewire everything. I reached out to Aerial Specialists and they have found the right circuit board for the machine. I am going to rewire the basket controls and clean up the mess of butt connectors added in over the years. Thanks for sending me the picture of the right circuit board! I will update with what I find as I go.
