Massey Ferguson 130 - hydraulic lift.

[fymiatacz]

Good morning,

3 years ago let's say I renovated hydraulic system.

a) oil change
b) seal on the piston replaced
c) filter under PTO replaced
d) hydraulic manifold checked (one of the small pistons inside got stuck).

Now I can see that lifter has issues with more heavy loads. I cannot lift 200-300kgs. If the oil is warmer, it's getting worse. Without the load the lift arms go to the given position.
When it's loaded, I need to press gas pedal.

My questions:

1. Pomp needs to be renovated?
2. Emergency valve needs to be replaced?
3. There is a scratch on the cylinder inside that provides a leakage for the oil when the pressure is higher?
4. All above?


I've read in manual that in 0 point (triangle between end of the arm and pull rod) the max capacity load is 1000KG that's incredible I cannot use it in my MF.

Can somebody help me please?

Get a pressure gauge and see what pressure you have

I think 130 has a gear pump rather than the usual ferguson piston pump. Gear pumps are more prone to wear. From description of higher revs needed and worse with warm oil I would suspect the pump.

Have you replaced the output filter? Under seat in top cover?

That's correct.

No. Where is it exactly? can you show it on a picture?

I checked with the gauge on the external euro socket and it's 50BAR on full throttle.
is it OK? I don't think so.

Filters

Filters

There is no such filter at on the top cover.

 

[two-cylinder]

There is: I have a 130 myself and have changed the filter
It is located on top of the top cover under the front of the seat.
Undo the two bolts labelled A on the diagram and lift the whole assembly off.

 

[fymiatacz]

this is something I've got in my MF. As you can see, there is only a rectangle cover with possible extension.

 

[fymiatacz]

I've got only this.

I can see also on this diagram there is a filter after the pump.

But in my case it's only filter below PTO and the pomp.
Then it goues stright to the manifold (bloc verin-distributeur).

 

[two-cylinder]

I've got only this.

The filter is in the housing beside that!
Undo those two bolts and lift off the cap and housing underneath and the filter can then be removed out the back.

 

[two-cylinder]

So someone has moved the filter housing and discarded it?

 

[fymiatacz]

It seems to.
Please see what I acutally have on my top cover.

This is where a selector valve for trailer tipping etc would be fitted, the long bolts suggest one has been fitted in the past and now removed, presumably along with the filter housing.

The 50 bar pressure you are getting sounds low, 150 -170 would be more like it?
