Massey 7618 power beyond

[DMcGrenaghan]

I have a 7618 and recently upgraded my silage wagon which is set up for power beyond, tractor had a return pipe coupling already on but the other two ends where blanked of, I put couplings on them but the wagon won’t work the hydraulics until I pull a spool leaver or turn steering, I can see it trying to work but just not getting the flow until I get the pump going, is there anything else I need to check?

There was a problem on the 7618 with the load sensing , does it work if you put your foot on the brakes ?

Yes it works when I press the breaks, do you know what the problem was with them?

Common issue with these. The load sensing line needs plumbing into the load sensing pipes on the rh side of the spool block using a special t piece with a ball bearing inside it. I can’t remember proper name for it. Your local dealer should be able to sort you out with the bits needed.

That looks nothing like our old 7618 it looks like a cobbled up job (no offence ) ours worked perfectly fine maybe it had already had a mod done to it though

There is a mod kit to go on it as , the other guy says the oil is not geting to the pump to ramp it up & make oil flow , your 7618 is a normal look back end on them , as i say you need this kit from a Mf dealer it has some valves & pipes & a T pices to make it all work

Did you turn the wagon to load sencing

T piece with a ball bearing inside it sounds like a shuttle valve but my load sensing experience is limited to New Hollands

You can put a kit on it but if you want to do it cheaply just move the load sensing line.
