    The JLG 40F Boom Lift Dilemma

    Thanks for the quick response OFF. Yes all functions seem to be working except the steer cylinder. Best way to find the steer valve is just follow hydraulic hose back to it?

    The JLG 40F Boom Lift Dilemma

    I have a 40F Thats been sitting for a year. I parked it when I blew a hose going to the tilt basket. Just changed that hose. The old girl fired right up. Everything is working good Except the steering now! Had no problems with steering before it was parked. When you turn the switch for the...

    Just popped hydraulic hose tonight on the basket up and down. Any tricks in changing this line? Anything to watch out for? Looks like a long hose!

    OFF Once again you saved the day!! Put a jumper on the solenoid, and that was the problem! I will pick up another solenoid at the parts store. Looks like the standard 12 volt solenoid. I want to thank you again!

    The JLG 40F Boom Lift Dilemma

    I will hire you today! My 40f worked fine last fall when parked. Tried to get it going today. The drive, lift, swing will not work from the ground control or basket control. Is this more apt to be an electrical problem or hydraulic? If its electric would it be the wiring in the basket...

    The JLG 40F Boom Lift Dilemma

    Hello. My 40f has been doing good over the years. However it has developed a new problem. Everything works as it should. But when the lift warms up after 20-30 min of use the going up goes really slow. It will even totally stop moving up after a while. All other functions work fine after it...

    The JLG 40F Boom Lift Dilemma

    Took that cylinder apart nothing is ever a quick fix! Found a lot of broken beleville washers inside. The very top of piston housing is scored from this. Although I think it's still usable because its high up the piston won't touch it as it moves. The problem is where to find the new washers...

    Yes it's the piston leaking. I have the piston off now. Hopefully once we take it apart it will be a standard size o-ring or seal I can buy local.

    The JLG 40F Boom Lift Dilemma

    Thank you OFF for the manuals. I have a feeling I will be looking at them everyday for a while! I think I found the problem with the swing brake. I saw a small drip of fluid coming from the cover. Took the cover off and brake is covered in hydraulic fluid. It has a leak! I could not pin...

    Yes its the swing boom. When the boom is extended beyond the half way mark you can grab the basket and push the whole boom. Do you have to take the swing motor off to get to this brake? Besides this issue the basket rotate is not working, I am hoping its just the switch, I haven't checked it...

    One more post after this I can pm you Off to get that manual! Just took the big boom cylinder off and had it repacked. Not leaking any more! Not a bad job but very heavy!! Just purchased the 40f has a couple bugs to work out. It sat for almost two years. Any ideas why when the boom is...
