FEL hydr. adjustment

[shovelrider]

Ok, i bought a newer Prince loader valve. Which came pre-adj. at 2000 psi(i guess), and i don't have a oil filled gauge mounted yet. My question is can i adjust it maybe 1/4 -1/2 turn and still be good for 2500-3000 psi. My cylinders are good for around that pressure. Any pictures of or suggestions wher to mount one would be appreciated. Jim

I am not familiar with your particular valve but the ones I use have shims to set the pressure.

I don't have a gauge either.. I just turned mine in uptil it picked up what I thought it should be able to pick up

 

[shovelrider]

Yep, that's what i did after posting. Enough, but not too much so that anything is leaking or making a noise. Txs guys

Well wouldn't you know it. The only cyl. that i didn't have rebuilt, blew.LOL. Since this is an old loader and they have the older snowplow type cyl. on it. I going to order 2new bucket cyl. and two new lift cyl. 2500-3000psi's each. Would my pump be too little for these, or can i get a bigger pump mounted? 79'ym1700

Well...I'm not sure...but, will the rest of the tractor (front end) hold up the additional weight you wish to lift?

Cranked up the pressure, broke something immediately. I think that's a sign ....

the New loader valve is set 2000psi, i read directions said 1 turn=200psi. I only went one turn, what i am saying is that the only cyl. that didn't get rebuilt was the one that blew. These things where made 70s-E80s, lord knows what all they have been thru, until i got them. They would lift my Bobcat welder(535) no problem. After having them done twice, now it's slow and easy. Or they start leaking(drip,drip)@2000psi. Worn out i guess. So, with screen cleaned, full of fluid will the pump handle cylinders & valve set at around 2500 psi. Would be my next question. I think i read pump out-put is 2035psi?? Or is say 800lbs. too much for these 1700s. Thanks

The old I&T shop manual states relief valve on the 195 (1700) should be set at 2200psi. This is the relief valve in the 3 point control system.

Don't trust anything but a gauge

 

[shovelrider]

I've looked online, but haven't figured out where exactly to put the gauge. Valve has PB, and i have a PB adapter(plug or what ever it's called). Pic of one mounted would be appreciated. Thanks Jim

 

[LD1]

Put it in one of the loader ports and operate the joystick in the direction that controls that port

Have you got the valve mounted and power beyond hooked up?

I mounted a gauge in the line coming from the hydraulic pump and before the loader or 3-point. (photo) This is at the the Divider Block that is OEM on the US Yanmars, (photo) in the line that is going from the block out to the loader.

I learned from watching the gauge to never pull on the three-point lever and a loader control at the same time; I've seen that gauge peg hard at its 4000 psi limit doing that.

 

[kenmac]

lol,I should add a gauge just to see what mine is putting out..I have my loader valve maxed out.. It will pick it up or the relief in the valve will trip.. Most times I just lift the back tires odd the ground

 

[shovelrider]

No sir, PB is still plugged from factory. But i do have the fitting to insert in if i need to use(log-splitter etc..). I will have to take pics today showing where my FEL connection is and side of tractor where i think my housing for my hyd. oil filter might go. As far as putting gauge in valve , LD1 are you saying tee it off one of my(say Lift) ports, so i can see how much press. is being used at lift ? Thanks for all the info. , i will add pix ltr. today. California, i have tapped into the press. line coming from pump to the area under seat, but i understand and thank you. Jim

 

[LD1]

You can either tee and dead head a cylinder, or just unhook the loader hose. Dont know if your machine is equipped, but most have quick disconnect loaders, and thus quick disconnect fittings. So buy a quick disconnect fitting, disconnect a hose, and pop on a gauge (threaded into the quick disconnect)

 

[shovelrider]

Here is my quick connect, and the hose on the left in the second pic is " IN "on valve. So, should i add (Tee into) the line going off the valve to the loader(lift-side) to see how much pressure is going to it? I think that is what you are telling me. Thanks Jim

 

[winston1]

This is going to throw a monkey wrench into your plans so you will probably just want to ignore it. Having the quick disconnects before the loader valve can be bad. If the line from the pump to loader valve gets pulled out for whatever reason your pump will dead head. The correct way is to put 4 quick disconnects on the control valve going to the loader cylinders. Mount the loader valve permanently on the tractor. Then when the loader is removed you unplug the loader lines.

Gottcha, will see if i can do this, however i don't think so. My ports are on the end(clearance issues
