Loader How to increase loader lift capacity

[Turbys_1700]

Everything mentioned here is correct...
I think that many on here, myself included, tend to over analyze things...
When I added a FEL to my 1720 I investigated all major brands and looked at lift capacity, height, ect...
I decided to go with a Stol FC 350...
I told my dealer that I wanted to be sure that the loader would curl the front end of the tractor off of the ground...
I was aware that some New Hollands had their pressure set low from the factory and in some instances this was an issue...
My dealer set my pressure relief to factory settings prior to installing the FEL and I have been very satisfied...
My loader will lift around 1000# and this is a good match for my tractor...
I think that my front axle is rated for 930#...
Again, If I wanted more pressure I would have no problem in bumping the pressure up...
Just make sure to stay under the load capacity of your front axle...
I have no need to adjust mine...

Here is a kit from BXpanded Hydraulic Pressure Testers that includes instructions on how to test your pressure first. Your pressure may be below spec like mine was.

Thanks... I will be sure to pressure test before I do anything.

Please continue the discussion.

Pundit considers pruning comment unnecessary. Discussion appears to be going forward regardless.

If you are looking to get a little more lift capacity out of your loader then a pressure check and adjustment, if necessary, is a good way to go. I was looking for more lift capacity with the LA302 on my B7500. I did check my pressure first and saw that it was close to the factory spec. So after reading a post by Mars who changed out the lift and curl cylinders on his John Deere I was inspired to do the same. I know that there are guys on TBN that will say doing something like this is unsafe. But I know there is a fair amount of safety margin in the design of the loader frame and other parts of our tractors, like the front axle as long as we are careful with moving that heavier load. The extra lift capacity is something that is typically used occasionally which decreases any possible problems. Realize that you must have the necessary counterweight on though. Here is a link to my thread for this conversion: http://www.tractorbynet.com/forums/...-my-loader-upgrade-completed.html#post2506029

Where can I find my Hydraulic Pressure numbers? I haven't been able to find them, guess I overlooked them.

Look in the Specifications section of the operator's manual.

Ok... my BX panded hydraulic pressure kit finally arrived.... but I can't find factory specs for the pressure relief valve... anyone know what the pressure range should be for b2320?

Rated pressure is listed @ 2000 http://www.kubota.com/product/B2320/pdf/b_series_spec.pdf

You should know the pumps max pressure in order to set the relief pressure. About 50 to 100 psi below the pumps max pressure.

Before the loader was installed, the hyd block relief pressure was set for the 3pt, and you also have the 3pt relief valve pressure.

Tractor hyd relief pressure may be higher then implement relief pressure.

The lowest relief pressure in the first valve will set the pressure for the rest of the system.

For instance the tractor relief could have been set to 2500 psi, but now you have installed a loader with a relief valve setting of 2000 psi.

That means that the new tractor relief is 2000 psi.

The loader valve is the relief for the whole system. There may be a relief for the 3pt but it will be set at about 3100psi.

If your 3pt valve relief is set to 3100 psi, and the loader valve is set to a lower relief pressure, then the loader valve relief will set system pressure.

Should set both the same.

If your 3pt valve relief is set to 3100 psi, and the loader valve is set to a lower relief pressure, then the loader valve relief will set system pressure.

Should set both the same.

The 3pt relief is factory set and non adjustable. It is more of an emergency relief for the 3 pt in case it is over stressed with shock loads. ie; bouncing over rough ground.

maximus1277,

I believe the B2320 has shims to adjust the 3pt.

If you have a loader installed, set both reliefs the same.

Your loader valve might require turning a screw or selecting the correct shim to set the pressure.

 

[maximus1277]

Ok... Finally got to a pressure test. 2000 psi at red line... Tested at the loader. Still would like to bump up the pressure just a bit. Where exactly is the pressure relief valve on the b2320?

 

[LD1]

You will most likely be fine you up to 2100-2200, but I wouldnt over do it.

Others will have to chime in on the location. But FWIW, on my L3400, it is on the block where the hydraulic filter is under the right foot-board.

maximus1277,

Show us a picture of your loader valve.

On most loader valves, the relief valve is close to the input hose.

Some reliefs are on the hyd block.

IF you have remotes, that valve will have a relief valve.

 

[maximus1277]

I found it... the valve is tucked in on the right side of the transmission housing... I will swap one shim and recheck the pressure... Thanks for all the help.
