    Komatsu pc120-6 low pressure.

    Still confused why PLUGS 3 and 4 in first picture states that its LS VALVE DELIVERY PRESSURE and in the 2nd picture the same plug 3 and 4 states that its PC VALVE DELIVERY PRESSURE. How much pressure standard should i get in PLUGS 3 and 4? Is it the one says 3/5 or around 3000psi? Thanks @LACHAU .

    Komatsu pc120-6 low pressure.

    Hello @LACHAU ! What do you mean by 3/5 of pressure? 3/5 of main pressure? Ex i got a pressure of 5000psi therefore LS pressure must be 3/5 of 5000 = 3000psi LS Pressure? Thank you
