Ford 4600 lift problem

Seven Gables · May 29, 2019

I guess ar this point I would pull your selector valve and flow control valve, one at a time and carefully take them apart and look for any worn seals, weak or broken springs, hairline cracks in body or build up of sludge/dirt. I've never had either one apart so I'm not real familiar with the tear down. Does the flow control (F-S) rotate freely? Also the selector valve, is it getting full movement when you switch from loader to 3pt hitch? One other thing, do the position and draft levers move freely and independent of each other? B

The flow control valve adjusts smoothly, the change valve also changes well. The levers also work smoothly, at first glance everything works very well.

Where to start checking springs / o-rings? from the valve under the seat or from the distributor whose diagram I added in the picture (in the picture in the lower right corner)

Good question, was hoping for simple fix. I've owned a few ford tractors but none set up with that selector valve. All of that vintage did have the flow control (f-s), never had any problems with it so kinda blind to their workings. You might pull the 25 and 21 plugs on the flow control and have a look at the Springs , plungers, orings and also just to see if everything is clean. Same with selector valve. Maybe somebody with more knowledge or has had this same issue will chime in. One other question, what is the little blue lever in first pic under seat? Never had that on any of my fords either. The next time I'm at my new holland dealer I'll ask one of the mechanics their opinion of your issue. B

The small blue lever in the first picture is from this distributor to reduce / increase the efficiency of the hydraulic pump (I just have it in the cabin and some have it like in the photo number 2 directly on the manifold).

Tomorrow I will try to undress number 25 and 21 and see if this is something ...

Ask how you can deal with this New Holland dealer about my case - you can help me ....

Ok now I think I understand the blue lever goes to the flow control on your tractor . Does the flow control that the lever goes to look to be the same as the flow control in pic 2? I've never seen one that way. And yes I will talk to my mechanic at dealer to see what his thoughts are. Is there a new holland/ford dealer in Poland? Near you?B

Yes, you think - it's a flow control lever. This is the lever that is on photo 2.

I have no New Holland / Ford dealer in my area; (

It would be very nice to me if you asked a dealer about my problem - he could help me fix the fault.

Looking through the diagrams I also found one valve that can cause my problem is the valve n 22 of the photo which he adds in the attachment. What do you think ? The question whether to get to it just unscrew the selector, do you need to raise the entire elevator cover?

Pic #2 is a flow control valve, my ford tractors all have this exact same flow control valve. I don't know what the small lever in your first pic is, do you know? What does it go to on the other side of shroud? To get to #22 I think you have to remove heavy top off rear axle. Yes I will ask my dealer mechanic the next time I'm there, I've been extremely busy, can't get out of the field. B
