Definitely try that first but your pump might be weak.

Yea the pump is dead. Motor runs fast but acts like it is low on fluid...I'll just get a brand new used pump. Thank tho.

Great!

It should have a pressure and a tank port/return you’ll have to get a spool valve of some kind run you’re in an out from your pump and then you’ll have the spool valve to reverse the flow to whatever you’re working.

@@backintheshop9604 Awesome! Thanks for the quick response! The pump is a hydr-app 24 volt that I just bought from eBay. I am going to use it to power a hydraulic lift mechanism on an rc track drive robot. I have a mill and a lathe, so I might machine a spool for it to make it double action later on.

On a normal daily used situation I would recommend at least one 850 cca battery. But it’s a good idea to have to hooked in parallel to double the amperage.

It should only have one pressure relief/adjustment the other one might be just a plug.

Is yours gravity down?

@@backintheshop9604 Mine is, do you know a way to slow?

Yes I’m just learning about this myself you can get an adjustable flow valve for about 60 bucks You can find them all over the Internet.

I have 2013 f550 dupm dont work I press the raise button and it doesn't do anything it doesn't make a noise like it's dead can you help please? 

They should be same. If there not you probably have a bad solenoid.

No there’s no way to speed up the pump if it’s an electric one.

you’ll have to find a hydraulic schematic for that particular pump, or check with the manufacture.

Yes, your solenoid is most likely bad. To use one as a double action, you just have to have a spool valve with a in and out and then you can use it to control the direction of pressure.

@@backintheshop9604 My solenoid on a older Fennel fluid pump doesn’t have a part number on it. Are most solenoids coils within the same voltage interchangeable or are they pump specific? Having a hard time figuring where to start my part replacement search.

@@truhawaii5957 most of the solenoid coils are the same either 12 or 24 V but I’m pretty sure the work on either. The part that’s different is the stem or mechanical part that the coil fits on that is going to be more specific to your pump you may be able to remove it and take it to a local Hydraulic shop and see if they can identify or match it up by dimension.

It's never a good idea to change the pressure over factory spec with dump trucks / trailers they usually get worn out from contamination dirt gets thru the breather wears out the pump and the lift cylinders but the weakest part is probly the piston seals on the lift cylinder

@@troywiseman5516 just seems odd this dump trailer has never been able to dump anything over 6000 # and it’s rated for 10,000# I’ve owed since new!

I did this to my dump truck and busted the pressure hose, so had to upgrade to a 5000psi pressure hose

@@ViVA-MEXICO-AMLO I’d be more than happy to do that if that’s what it takes to dump heavier loads as it should…..very frustrating getting 3 yds of trap rock and the dump trailer won’t dump it…..doing it by hand is defeating the purpose of using a dump trailer!

Is it electric solenoid control for the down function?

Yes bud, basically same as yours but mine has square oil reserve.

There’s no way to adjust electric valve You might need to try to find one with a higher flow rate.

@@backintheshop9604 Thanks for your help, that answers my question.

Not sure your set up but yes it should work.

Lifting and turning is all in the valving you use the levers and valves, most bucket trucks only have one pump on them but they have to be dual action pumps.

Mine just has a power and a ground hook up. The solenoid and remote are already pre-wired. I just tapped into there is no wires for my extended remote. You should be able to look up the model of your pump and find a wire diagram on Google images or the manufacture website.

If there’s not trash in the pump valves and they look fine the cylinder probably needs repacked.

You will want to set it to 2200. That way you don’t blow out your cylinder when it hits the end.

All cly have a safe rating and best not to ever go above it😊

Check the fluid level, make sure all of the couplers are actually releasing, so the fluid can flow other than that. You may have to disassemble the entire thing and do some investigating.

Fluid was good. I swapped the pumps with one I borrowed and used the hoses and the cylinder from the kit and everything worked normally. So it's something inside the pump. And that's were I have an ignorance overload.😅..I just can't grasp the overall mechanics of the thing until someone explains it to me.. I have the vevor 12 ton jack.

Sorry for going off topic. I don't normally do that..

Lifting more but it can also damage the pump if you over the limits

It sounds like one of your Solenoid valves is bad. You’ll have to figure out which one controls the arms. If it’s clicking the solenoid it self should be fine but I would check and make sure you have a good 12 volts to it. The valve threads into the block and the solenoid fits onto it you remove the solenoid and then unthread the valve. The pressure relief valve it’s just for Max pressuring you shouldn’t need to adjust it it’s been working

Got to check for power.

Got to check for power.

How can I do that. thanks I will share your video it helps a lot of people save money

@@mariochavez1824 you need to take a volt meter and check all your powers and grounds.

As long is it has two ports a single action pump can be used for anything with the right control valve.

@@backintheshop9604 I understand all that believe me I have worked on plenty of them, but what you said in the video was that all pumps come with two ports and that is not correct, you can buy single action pumps with only one port like the two I have, they are designed to replace PTO pumps that gravity feed back down on older trucks like My 59 Ford dump truck. You said you have never seen a single acting pump with only one port, I just wanted to let you know they do make them and they are available for people who need them. Look up part number 36NE08 on the Grainger website and you will see what I am talking about ..One port single acting pump, not two ports. I think your doing great with describing thing and how they work, but if you tell people that all pumps have two ports, then you are misleading them, because there are plenty of single acting pumps with only one port on them.

Oh okay I understand. Yeah I haven’t personally seen one with only on port. I guess if you needed to change it you’d have to installed a return port in the tank. Thanks for the info.

I will check your battery. Make sure it’s good and all your connections are good. If that all checks out I would say you have a brand new defective pump.

Check your ground, it has to have very good connections to work Check stem on solenoid for rust Happens to new ones also

Mine does the same thing. Take a small hammer. Tapp the motor. Tap it on the end. Or on the side. Or on top.. I have to hit mine on the negitive post

Mine has 2 also. 1 with a cap on it
