Hello gang,
It's been a long time ...
Today, I finally added a pressure gauge to my LW-8 Backhoe. You may remember that I got one from a friend, then fixed it all up and made a custom sub-frame for it to fit my 55HP Kama.
This is the name of the thread about it: "Diamond Shape Sub-Frame for LW-8 Backhoe" with lots of photos.

Anyway, here is my question ...
Does anybody know what the max PSI I should set the pressure relief valve on the LW-8?
It has self contained hydraulic system with a PTO mounted pump.
After installing the gauge, I found out I was getting only about 1,700psi !!
Right now I've adjusted the pressure relief valve to 2,250psi (same as the tractor hydraulics). However, I thought I remembered reading that the LW-8 and other Jinma backhoes have a higher relief setting than that? Maybe I'm wrong, but it doesn't hurt to ask all you experts out there.
If you want to see some photos of the gauge mod, I can take some tomorrow and post them.
Thank you,
Rob-
