I am not sure I think 2400-2500 is around max not near my book. Anyway I got a 3000 psi gauge and a female quick coupler like is on the loader hoses from tractor supply around 25 dollars total. The shims are like a number 10 flat washer one size smaller than a 1/4 inch flat washer. 22 mm wrench fits the valve and look under the right floor board. I have mine around 2500 and have done several L3400 one guy had me set his at 2600 due to using it to load logs at his saw mill. There is a big difference now vs before I was told by my local dealer Kubota always sets them low at the factory.
