hey everyone. I am wondering about my 190 hydraulics again. my gauge from Napa reads only 1200 psi. I installed a relief valve that is supposed to be pre set at 2000 psi. however when the tractor is running 1400rpms If I engage the remotes it strains the engine. gauge still only reads 1200 psi. could the gauge not function properly if there is air or something in it? it is a 5k psi gauge. or is the hydraulic pump going out? the previous owner did redo the pump so I am guessing It is still good. thanks

Multiple times you were told to check pressures at 2,000 rpm or more. Why aren't you ?? Never have you said who you bought the tractor from had just been thru the hydraulic pump. This would have been nice to know. A 3K gauge is better than a 5K gauge. Re check at wide open throttle. Adjust the relief valve "in" 1/2 turn at a time and if you cannot reach 2,000 psi you have PUMP trouble.
