Thanks for the info. ATCO, and thanks for your patience on all of this as well.
That makes a lot of sence. The line doesn’t seem to flex well.
Wow OFF, a set of readable 40F drawings...that's sweet and rare.
I found my old stash of JLG treasure, not only 40F in Bertea, but also in Racine, PQ, and Cutler/Hamer.
60F in all configs, even Moog/Moog, 80F racine, and 40G.
LoL, you realize that you probably have stuff there that not even JLG has now? When I was training at JLG, they had a 40G in front of the building. That's a rare machine.
A company I worked for from 82 to 84 had a pair of 40G 4x4's. Nice machines.
Yeah, I've got all the factory size 17 x 22 drawings. Some of them are even original "blue print" blues.
Also in those files were all the internal diagrams for the latching relays and lockout systems. I''ll pm you my contact info, if you ever need that old stuff, just rattle my chain.
LoL...at present, I'd just like to have the wiring schematics for the 40F.
Oops, the pictures in the thread didn't open for me till now. I see you've got Bertea valves. I don't have a specific schematic for Bertea.
I do have clear ground control & main control box diagrams, the wire colour codes and numbering should be the same.
On your hydraulic oil question, in the dark ages we used HVI22 hydraulic oil cut with 50% kerosene in the winter time on these machines. That was the only way they would operate at below -30. Even then they had to be run on ground control for an hour to warm up the oil enough for the valves to work.
Later on, we discovered Amsoil synthetic ATF and used it with great succses. These days they are making HVI15 hyd oil which is a lot better than 22 was. We use a lot of synthetic 0W30 in hydraulics now. Start & go at -40, no problems.
According to the factory "bill of material" sheets for the 40F Racine, they used
15ft of 16/3
6ft of 16/12
64ft of 16/24
64ft of 12/4
all of it SDN ITT type cable.
Hope that helps.
If you've got PQ controllers, I have 3 new cards and lots of assorted used parts for them.
Soon as I figure out how to scan a 17 x 22 sheet of paper :beatsme
I need some help, my pq controller for my JLG 40F is not working. This particular controller uses PWM (Pulse Width Modulation) does anyone have any working boards I could obtain? Even a schematic of the PCB might be a great help.

Are you having an issue with all the controllers? Or just one? Describe the probelm your having as best you can.
BTW, welcome to the forum.
