MF 6290 help

[snipe]

Anyone know where the Hydraulic low oil pressure light sensor is on a 2002 6290. It’s definitely not closed centre, might be open centre, but most probably twin flow hydraulics. The low oil pressure light is on but steering works ok and the autotronic (dynashift, pto, Rev counter, rear linkage) has stopped working. I was going to pull the plug off the low oil sensor and bypass it to see if it made any difference. But don’t know where it is or what it look like. I have pulled the plug off the the switch in the first picture and made a circuit with the plugand this did not effect anything. Then I took the screw plug off in the second picture and this made the transmission oil filter blocked/ boost oil pressure light come on. Any ideas.(picture 2 needs rotating 90degrees clockwise) @fergiedoctor

I think you will find the gear has broken off the end of your hydraulic pump

If you unscrew the speed sensor out of housing there should be a gear in behind the hole if you poke a screwdriver in hole gear should be tight and if gears not there that’s your problem

Had the same problem last year but it was an electrical problem. The fact you have lost the dynashift and pto makes me think it could be the same .
The switch could be faulty either its beside the filter .

The switch beside filter is either filter clogging light or 5 bar circuit
That will not be the fault

Would that cause the low pressure waning light to come on?

Aye youre right come to think of it , my 6290 is closed centre hydraculics and exibited the samel loss of functions . Turned out to be a bad wire in the loom . Big job to get the pump off ???

If the drive gear if of the pump and lying in bottom of transmission I would think so yes??
