Massey hydraulic pump

[Ferguson165]

Anyone know how to adjust hydraulic pump (load sensing system) controller. I know these pumps are adjusted from factory, but mine has been touched.

Do i need to dead head the pump? (plug the line going to distribution block)

Tractor is mf 8120

i dont now how to but why are you wanting to adjust it ? it might be something else that is at fault

Because the control spool adjustment screws were taken completely out when we got the tractor, pump might be gone anyways because hi/lo synchro was broke, but would like to know pump condition before buying new one

I got it adjusted, now after bleeding clutch and brakes and finally trailer brake. when pushing both brakes together pump starts labouring? .i did clean spools from distribution block and trailer valve block.

That sounds normal it’s the trailer brakes loading the pump, does everything else work?

Yeah everything else seems to work. Do you know does the linkage system need autotronic computer to work?
