Anyway to make my loader lift more

[kennyd]

Looked at the loader control valve and mine has 4 hoses each connected via a quick connect (like an air fitting).

Was thinking of hooking up a pressure gauge to each one and see what I get. I feel this is an accurate test. Is my thinking on the spot or will I need a loaded bucket?

Yes, that is correct. You just need a 0-3000 PSI gauge, a short hose and a QD nipple that fits your couplers. Below is a picture of mine. Just plug it in, then operate the joystick to send fluid to that valve-the engine should lug down a little when the PRV (pressure relief valve) opens and it's setting will be displayed on the gauge. Only hold it there for a few second at a time. Also do it when the tractor is warmed up. In theory, you only need to check one port also.

The hyd gage should be a 3000 psi gage.

Just install the gage in a tee fitting at the IN port, and leave it there for any future trouble shooting. When you activate any valve, you will see the operating pressure. If you hold the lever to full extend or retract, you will see the relief pressure.

I always taught my kids not to chisel with a screwdriver, too use a tool in its intended manor. I would suggest to tune your machine as advised above and make some extra trips. Nothing better than a safe day without a breakdown.

Thats what I am thinking. Never had a tractor and didn't know if there was a way to "tune" a loader. I work around cars and know how to get more out of them with simple modifications that do not affect the car besides adding to the overall performance.

To my way of thinking too much weight in the FEL makes the tractor scary to drive. With a counterweight on the 3TH and a heavy load in the FEL, both of them raised up in the air even a little you can dramatically raise the center of gravity of the whole machine. It can tip over. R1 tires have weaker sidewalls than R4s, turning them significantly with a very heavy load on the FEL you can see them practically fall off the bead. So, as others have said, I'd take it easy and make more trips. Underload and drive a little faster or overload and drive a lot slower, it all probably comes out even in the end.

One way to test loader. One gal of water weighs 8 lbs. One 55 gal barrel full of water weighs about 450 lbs, including barrel. Three barrels weight about 1320 lbs. Cheap way to test if you have the barrels.

JJ, where would the "in" port be usually? Is it marked with a stamping or...?
I have a Deere 2520,if that helps. Also, do you know of a link to a hydraulic tutorial ? Thanks!

The IN or P port should be stamped on the valve. The IN port will have a relief valve close by.

There are some hyd cd's on Ebay, and bunches of hyd stuff on the net. There is the Army hyd manual.

The FEL valve is mounted directly to the transmission on your 2520 so it's different than whats being discussed here.

What are you trying to do?

I would like to make sure that my pressure relief valve is set within spec's (mines a month old) ....mostly just to ease my mind. Also, I want to understand the usual procedure/mechanics of a typical hydraulic circuit...as this is new to me in away..... (I've been in the HVAC business for 32 years now,I work with pressure/temperature everyday. I'm very well versed in electronic and pneumatic controls and these controls are one of my specialties). I should pick up on hydraulics fairly quick as its so similiar to pneumatics....just a different medium with different properties. But want to learn the everyday mechanics/procedures for it....as well as what is available (types of control valves ,etc) to achieve certain goals when designing a circuit.
thanks
