Hydraulic Pressure Gauge

[johnnylight]

looking to build or buy a pressure gauge to fit/test the 14LA loader.
I tried this: Hydraulic Quick Disconnects

If I build one what will I need?
What size are my fittings?
Where can I buy a ready to go set up (that's if there's such a thing)?

Thanks

When I made mine, I just went to the dealer to get the QD nipple, I might have paid a little more-but I knew it would fit. The gauge and hose I bought from the SurplusCenter.

I do not think your will find a ready-made unit.

Make sure you secure the guage when using it; pressure spike can straighten hose and break guage.

Kennyd,
Thanks, that's exactly what I needed.
nice job building your own.

dqDave1,

will do -thanks.

Here is a picture of mine. It's just a gauge and an adapter screwed into a QD. It works great. I have never been in a situation where I couldn't spin the gauge in the QD to see the dial.

That's exactly what I use. . .the "Kiss" principle.

 

[johnnylight]

just checking before I order one.

Is this one the way to go?

Yep.. gauge on nipple.. easy...

Yes, that's perfect.

 

[3RRL]

Yeah, like Kenny said that one is perfect.
That idea of making a QD gauge is a really good idea. I wish I would've thought of that.

I ended up going the longer route but it was very helpful to me.
I installed a pressure gauge on my wife's Jinma right into the hydraulic system. I understood her system had no pressure relief valve of its own. Only on the control valves in the system had PR in them. So if the valves were ever taken out of the loop (such as when the loader is removed) then the pump could dead head and get ruined if the "in and out" were not connected together for some reason.
This being my wife's tractor, I thought that was a pretty good reason.

Not only that, but I wanted to check her system pressure BEFORE setting each valve's individual PR. So I installed a PR valve right on the high pressure output side of the pump and a gauge right after that. The new PR valve has a return to sump when relieving. After the gauge I installed a QD to hook up to the loader valve and so forth.



The good part about this is now I can disconnect the loader valve at the QD and dead head the pump. By doing that, I can set the main system pressure exactly where I wanted, according to the manufacturer's specs. The pump is now protected by that new PR valve, which allows me to do that. Then, I plug in the QD which connects all the control valves and set the pressure relief on each valve individually using the same gauge. I set them just below the main system pressure.

I didn't do that on my Kama but did plumb a gauge into the system. So I can still set the PR of each valve, but I have no idea what my system pressure really is. I know all that is a lot more work and expense, but the good part is if for some reason I feel my hydraulics are lagging I check the gauge. Sometimes the PR spring weakens over time and needs to be readjusted. Now I can recognize if that happens and make the adjustment.

Rob,

I really like how yours came out -being able to know whats going on with your loader at all times nice way to go.


am going for the quick dissconnect-my problem is I dont know what size is the QD male. The manual shows QD male 3/8 for the TC34DA/14la FEL with that I called surplus center to order and they didn't know which one,they just want item numbers.
hopefully one of the pros on here know.

I'll keep it simple let's use GIJOES QD set up.

Thanks

 

[johnnylight]

Wow what a difference (Nice people) I called Hydraulic Quick Disconnects.
Thanks Rob.

gave them my info they will put it together to see what fits and send it out to me too cool --I'll keep you updated when I figure out the part numbers in case someone else needs them.

 

[3RRL]

Yes, that is VERY cool of them.
Show us what you get as soon as it arrives.

 

[johnnylight]

update,


The pressure gauge arrived with the wrong set. (1/4 QD coupler)
I ended up buying the connectors from NH.

part number# for bushing 87628 cost $1.83
part number# for coupler 9846344 cost $13.14
pressure gauge from #afc-3m-25 cost $17.50 Hydraulic Quick Disconnects

I tested my loader and here's the number am showing on the gauge 1800 psi.
Is this normal for the 14LA loader?

 

[kennyd]

1800 sounds low to me, but I have know idea what NH specs the machines at.

As for the wrong QD fitting...re-read my reply in post #2 of this thread-BTDT

Johnny,

Sorry to hear you got the wrong qd. This is why I always say to shop locally for this stuff. The cheap pay twice.

As far as a test kit, I can give you a short list for a neat little pressure test kit that should test most of your hyd circuits. BTW, I sell the same gauge locally for less than what you paid, and no shipping.

The following are Weatherhead part #'s.

C5706x4, C5706x6, C5706x8, C5706x12. These are JIC street run T's in sizes 4 thru 12. With these, you tap into the line you want to check the pressure of and run the T to your gauge.
C5015x6x4, C5015x8x4, C5015x12x4. These are JIC reducers and need the nut that follows to work. They reduce from the T to the gauge.
C5105x6, x8, and x12. These are the nuts for the reducers.
I also like about a 2' piece of 1/4" 2-wire hose to go from the T to the gauge. Makes life easier.

The pic below shows some of the fittings. There are also 1 piece JIC reducers which is in the pic. It doesn't matter which one you get. Everything I list should be able to be bought locally for a hundred bucks or less, ballpark price. I would have to look up everything individually to give an exact price.
Good luck, Andy.

Johnny,

Did you test the pressure at an idle or at the 540 PTO RPM. It does make a difference. Mine runs about 1800 psi at idle and 2200 psi at the higher RPM. I also have a completely different machine.

[Soundguy]

Hmm.. I'd want pressure to be more uniform.. even though flow will be lower at lower rpm.. etc. GIJOE Your system doesn't use a vane pump does it?

Johnny, I'm sorry you had such a hassle with your gage setup. I'm glad you got it all worked out.

Do you have an Owner's Manual for your tractor? If you look in the back in the Specifications section, it should have a section for the hydraulic lift or hydraulic system. Mine shows the system relief setting pressure in bars and psi. I think yours should too. It's worth a look-see. If you don't know what it should be, measuring the pressure doesn't really tell you what you need to know.

 

[johnnylight]

Kennyd
you were right I still had to look up the part number for the coupler I didn't have a old one to bring in but thanks to messnicks website I was able to find the part number.

Jinman,

are you kidding me who needs a manual when I have guys like you.
(not kidding)


ok I'll look
for the 34da system relief valve setting 2133 psi 147 bar
in the manual for the loader shows the same 2133 psi

So it cost $32.47 to build one
I lost $10 not a big lost with the wrong parts I'll find a use for that somewhere else.

I still highly reccomend the good people at Hydraulic Quick Disconnects
Check this out how to know which one is yours page 26

Gijoe,

I raised the rpm today at 2200 rpm the pressure gauge showed 2000 psi.
I don't know if you can read it in the picture.

133 psi would this make a difference?
