While it is true that anything can be screwed up,I don't think adjusting the PRV is rocket science.Take your time and pay attention to how the parts are assembled.From talking to the people at my dealership I was told 10 percent above the recommended pressure shouldn't cause any problems but I wouldn't go any higher.Some people might disagree.The highest pressure for my L45 is 2845 psi.I got the dealership to set it at 2950 psi which is less than 10 percent but I know the loader is working to it's full potential.I have owned four Kubotas with a FEL and I have made sure each one was set to get the most out of the loader.No point in having equipment that is not performing to it's full potential.Good luck with yours.

The bigger thing is an injection hazard caused by a leak or a loose fitting. If you jack then pressure way up you can start breaking things but the leaks are things to be careful of.

I wish I could do the Gomer, "Surprize Surprize Surprize". I followed everyone's advice from here and the folks at EXPANDED where I bought the "KIT" of a pressure gauge and shims. Their advice and the instructions that they sent for a B3200 with I guess the "thinking" is that all the B's are the same. I and most of you assumed that also. WRONG.........

Turns out that the loader relief valve is up on the loader arm itself on the B7610. There is a relief valve down on the hydro pump itself by the 3PH knob between the operators legs. NOT over by the rear tire and under the seat,,This relief valve is for the 3ph..........Found this out after pulling that heavy tire and looking, scratching my head, and then finally Messick's. Previous to beginning work I had looked at the Messick's parts diagrams and could not find the relief valve on the pump where everyone was talking about........Went ahead and pulled the tire and looked......NOTHING there.....OK......Les at Messick's was totally helpful with helping me figure out by looking at the schematic and the tractor, and by golly, there it is.....up on the loader arm itself. There on the front right hand bottom corner of the valve itself. The valve is that block of metal where all the hoses go in and out with the pressure relief valve there. EASY...........

For future folks looking at this wanting to increase the strength of what the bucket can lift on the B7610, there are 2 different valves and one of them does NOT have a pressure relief valve arm the arm. I assume it is as other folks have advised.........God bless...Dennis

Good to see you got it figured out.What was the original pressure and how much did you increase it?Are you now able to do what you wanted it to do?

OK, another update. Got the kit from BXtended. Hooked up the gauge to the up/down hose, yellow, and fired it up for a test. The original reading was 2200 PSI. Pulled the plug with a 22mm socket. That was the easiest part of the whole thing. It is right there exposed and one just reaches in and out it comes. Over to the bench to check it out. It has a couple of shims with no color and a blue one. Put in the .3mm shim/blue. Put it back together and got 2350 at max RPM.

I think, someone correct me that you are supposed to get 40 more PSI with each .10mm????? So the real test!! Just got 3 new 4'X5' round bales this morning sitting over there on the trailer. Rolled them off by hand, went up to them and stabbed into them fully by pushing against a tree. Put the lift and whoopee...... lol...... went up 3". OK a tech told me on the phone that 2500 is the top PSI. He had no manual in front of him but figured it out by the common sense method of if it came with 2200 or so then 2500PSI was max......HELP FROM SOMEONE WITH A MANUAL WOULD BE GREAT..........

So, 3" of course is far from lifting up a bale and stacking it on top of others. Back to the bench and added another .3mm. Now a reading of 2450 PSI. Result....... hold your breath......6". So...... what is the max PSI I can go with????? Would be great if it is something like 3K........At least I can now pick one up on the front and rear to move them. Also it is great to have the spear on the front to manipulate them. Like scoot them around, turn them over, and partially lift a corner to be able to get pallets situated..............

So, any ideas on top pressure???????............ Thanks for all the thoughts and encouragement......... God bless......Dennis

Here's a page that should help. Note the recommended pressure on the middle RH side of the page. Good luck.
