Hey Rick39,
Glad to have you on board.
Yes, that's it.
The pilot flow goes into the side of the stack on the inside. The fitting in the valve has a screen behind it.
Above that fitting on the valve is a relief valve for the pilot section, don't remember the pressure but around 300 psi or so.
JLG specified a flow to the pilot section but most people used pressure to set the divider valve.
I used to turn the adjustment in, then slowly out until the engine sounded like it had a slight load on it.
The dump valve has to be closed, so start from the ground controls and make sure it operates from the overrides before adjusting.
Make sure the pilot valves have a signal, best to check milliamps on one of the wires going to the pilot valve.
Don't remember the value, but maybe 500 ma at full stroke?
It has been mentioned before in this thread...a quick search overlooked it...what degree grade can these JLG 40 F machines climb?
Well, no one has expressed concern that the 40 F will overload a 14000 GVWR trailer.
I will take that as good news to move forward with a 14000 GVWR trailer purchase.
Rick39. Thanks for commenting. My JLG still has 40F on the boom....the empty weight of the trailer?...
...if the unit you have is actually a 40F...
...the configuration of your JLG...
...consider that the unit is fairly long which limits how it can be positioned...
...many variables...
Would it be possible to get a copy of Schematics,Parts Manuals for JLG40F. I'm a proud new owner of one. not sure on pump type yet ,was running 5yrs. ago . It's in good shape, 1287hrs. on it, there's very little wear on the machine. Been sitting outside in grass frame on ground. wanting to get to know more about it before i start it ,and get it dug out of ground . Thanks Paul.No problem arjaytee. I will begin sending them as I get a chance tonight. They will be in multiple emails so the size doesn't cause a problem in sending them.
HelloWelcome bayousammy! If you make one more post, you'll be able to send me a private message with your email address in it. Then I will send you the manuals. No worries, the party never ends.
Hello
Thanks Hello yes tires are going to have to be replaced they are rotted to bad, they have tread large cracks not safe to use. Maybe next week get it dug out back at shop to see what I've gotten into.Hello, and welcome Catz4! Hopefully the tires are ok on your "sunken treasure". Tires tend to rot when they are left un-inflated for long periods of time. That size rubber is getting really hard to find these days.
Get in one more post to unlock the private message feature, then send me and email address that I can send the manuals to.
