Massey 6465 tier 2 loss of drive,pto,4wd and diff lock

[Robstephens]

my massey 6465 2005 has lost drive,pto,4wd and diff locks. All went at the same time! The error code is t253 which comes up as low pressure (dropped below 20bar). Have had no warning signs etc just gone all at once while tractor was at work. Any help or suggestions much appreciated.

Sounds like the damping plate..

 

[Robstephens]

Forgot to mention that i still have spools and hydraulics. Which someone has said rules it being damper plates out?

Possibly two separate pumps, one for the main hydraulics and a smaller one for the auxiliary stuff?

@Robstephens
Couple of questions
Is your tractor dynashift or dyna 6
What hydraulic system does it have

 

[daveydiesel1]

Got mine sorted ther. Was blown 4wd diff lock fuse. Worth a try

If it's dynashift do they have the resistor in the loom just back from the pressure switch like the 3670.We had simaler problems with a 3670.you have to open the loom up a bit to see it but ours failed.a new one came with a short wire and plugged in between the loom and switch wasn't expensive and cured it .

Check fuses, most of those are grouped together

Have you got any steering? Most probably an open centre tractor with a tandem hydraulic pump, rear half of pump most probably has gone. You can check if you have flow to orbital unit first before whipping side plate with the pump off.

What was the outcome of this please? Just had similar with my 6465, it's lost 4wd, diff lock, pto and the lift arms. Also the dynashift is stuck in D. Recently had a damper plate, so don't think it will be that. Thanks
