806 hydraulics

[invcbl]

Hello all,
I am having problems with the hydraulic pressure for the steering/brakes/torque. Seems when the tractor gets warm the oil light in the dash comes on when the tractor is at an idle. When the rpm goes up the light goes off and everything works normal. It also works normal when the tractor is not warmed up. I thought it might be the valve but shouldn"t it act the same cold or hot??? I am leaning towards the pump but could use some info if anyone ran into this before. Oil and filter are new and this did not make any change when the were replaced. Any help would be appreciated.

Yes Sir,

90% chance that the front pump is getting a bit tired.

With out running a couple pressure tests and flow rating the pump your spitten in the wind.It may be a blowen o/ring in the MCV or weak springs may even be a gskt. Could be a porblem in the T/A it's self. Having some one test it first can save time and money .
