Check Valve

[arjan_brouwer]

I'm stuck and so is my check valve

As shown in the picture i god only the half out, as on topic http://www.fordsontractorpages.nl/phpbb ... ve+#p15233

Should i leave it this way?




As you can see on the picture, part 45 is still in.





Any advise?

Part 45, should be the check valve seat, it is very hard to remove without the special tool. Check the condition of your check valve ball to see if it is grooved, if it isnot then the check valve is unlikely to be the cause of your problem. If it has a groove, replace the ball and do not worry about the seat.

The seats are not available as far as I know.

Thanks Bryan for your reply.

As you may know I'm completely restoring a SM. This lift came from an SM with a broken engine. I don't know if the lift is working fine. I sure hope so. We will see...

hello, please what should be in the wide hole in upper right corner of plate (neareast left from the bolt)?
On my Fordson there is accurate plain bolt in this hole - is it right or should be there any valve?

Do not you know where could I be able to find the decription of the holes - where is the pressure etc.

thank you very much

Like a lot of the holes on the lift that one is not used. The important ones are the ones between the bolts which are pressure and exhaust and the large and small ones in the middle which are feed to the ram cylinder from the flow control in the Auxiliary Service Plate.

Thank you very much.

And is there any hole for the pressure for threepoint? - is it correct presumption that it take pressure oil from the one hole between the bolts and return it into the second one in operations with front loader of threepoint?

[KuaJA]

Please guys, am I able to operate threepoint through the leftmost hole (on the picture) without top cover? -with pressure oil from the source on the side?

[Brian]

Not without operating the lift. The pump will not generate pressure until the valves are operated. All you get from that port is oil at around 12psi.

There was a post on here about blocking the main feed to the lift, diverting the oil from the pump through a separate valve bank then continuing on with the oil back into the lift. Seemed a lot of work when either a PTO or engine driven pump can give better flow rates than the hydraulics on the tractor.

Brian thank you very much for your patient a sorry for my nontechnical english.
Now I operate the front loader with pressure oil from the port on the righr (throttle pedal) side without any problems.

I have got hose from the port to the front loader through the separate valve bank (single action) and the oil is coming back through the plain metal desk instead of the top cover - it flows to the hole which is on the lower right corner (on the picture).
My question is whether I can lead the pressure oil from the another port of the valve bank to the the leftmost hole (on the picture) and with this operate the threepoint?

I am able to stop the oil for other port of valve bank for front loader. For this I would have the same pressuere which is enough to operate front loader.

it works
I connected the pressure oil to the hole which is in the left upper corner (see the picture above) and the three-point is working without any trobles
