Massey Ferguson 8130

The lad I bought it off told me that he bypassed a hyd box /sensor so she is pumping constantly i.e. Not on request makes it a little harder start but don't think it affects it any other way

That's doesn't sound good it will get the oil very hot if it's pumping all the time, when your steering goes hard do the other hydraulic functions work ok?

Ya they seem to be fine. I reckon I should fix whatever he bypassed any idea what it is.

The only thing I think he could of done is tweek the standby pressure screw up on the pump but obviously there must of been another issue for him to need to do that

 

[willie8110]

I reckon what ever he by passed fillings have damaged he told me the two pumps are replaced but he bypassed this with a t piece il have to get a good look at another tractor to see the difference

The whole load sensing block could be full off filings! Yeh daved is right the oil will be boiling if its been bypassed! You should fix this bypass, and you will have a long rocky road abead off you but just have patience! Its worth it

 

[willie8110]

don't know is anything visible difference their

 

[Robert tubman]

Take a picture of load sensing block at other side

 

[willie8110]

can try to get better ones if they won't do

 

[davedb]

Looks like he's bypassed the load sensing block then, can you get some better pictures? I know the wheel will be in the way il see if I can get you a picture of mine but it's on 650 tyres and there ain't much room

 

[Robert tubman]

Seems to be what hes done

 

[Wellytrack]

Is this an Irish tractor @willie8110

 

[willie8110]

It is ya. Why do you ask

There has been a few of them doing the rounds. Did it come from a dealer?

 

[willie8110]

No bought it privately from a lad. Would their be any logical reason why it was by passed or would it be repairable or is it a new load sensing block

 

[davedb]

The block has probably got damaged from the breaks goin they arnt cheep but @masseybreaker mifht be able to help

It looks like he's used a solinoid valve when bypassing it I wounder if he's got it so you switch it on with electric to make the pump work? Is there any extra switches he's put in the cab?

 

[willie8110]

I'd like to have it right to be honest for the sake of a few euros. Will have to do a good bit more investigation

Your man has gone to a lot of trouble bypassing it by the looks of it, I'd be keen to sort it properly as you are saying all you can do is take the valve block off and have a look, the first valve is the trailer brake valve the second one that's nearest the gearbox is the load sensing valve

Those slices are 1k a piece but the geezer who bypassed it must have a fair idea of what he was doing to make it work!
I would fix it pronto though, having the pump going flat out ll the time won't improve it.

 

[willie8110]

Ya it seems fine but still I'd rather it be right in case it call other problems I'd hope it would be as simple as filings but time will tell. Whatever way is by passed the trailer brake valve doesn't work either

 

[willie8110]

slightly better pictures
