A lot of folks here and in videos state the BX is delivered with a relaxed hydraulic pressure limit, and will take up to 2000 psi. I got a gauge and fitting and checked, and at PTO speed (~3000 rpm) it maxed out at about 1600. Huh? Wasn't expecting that low.
I also bought from Messicks a .1, .2, and .4 mm shim, where you get ~40 psi / 0.1mm. I added the .4 and the .2 and it brought it up a bit over 1900. This increase effect wasn't astounding, but I did notice the backhoe bucket straining far less when curling it through soil. True test will be when I dig out another stump, as the last time I did this I wasn't real impressed with the power.
When making the adjustment, it took me longer to take the backhoe off and put it back on when I was done than it took to install the shims.
The most frustrating part of the job was trying the find all the parts for the pressure gauge at one store. Be it Northern Tool, Fleet Farm, Tractor Supply, they all left me disappointed as each of them were missing some piece. I finally gave up and found everything (gauge, thread adapter, pioneer fitting) in less than 10 minutes on Amazon for less than $30 total, including shipping ... so I'll offer that advice to anyone looking to do this.
