IH 424 Diesel

Hello! Seems there have been significant discussion on the IH 424 and the like pertaining to hydraulic concerns. However, I have yet to find the combination of set up I currently have and a resolution to the issue I am having. In advance, I would like to thank everyone that may be able to provide their insight on helping me find the solution.

I have an IH 424 diesel, that was originally equipped with only 3pt. I applied an open center hydraulic control valve (aftermarket) for rear live hydraulics for use of various implements. At this point I was having no issues with the tractor nor the hydraulics there of.

I found a 2424 parts tractor in which I was able to swap out the power steering front end (dual cylinder power steering system) over and apply it to my tractor. After installing the power steering to the tractor, I lost all 3pt operation while the hydraulic control valve used for my implements does still work, it does work a bit slower.

To alleviate similar questions I ve read in other similar readings, I will say
The control valve in front of the seat has been open/closed with the right hand control knob and the left hand speed/flow knob has been adjusted in all operating scenarios and still contains the same issue. The raise/lower and draft control levers to the right of the seat have also been operated in all operational scenarios. The front mounted hydraulic pump (original to the tractor w/ no power steering) is the standard hydraulic pump (not the Cessna pump) that was used on tractors with no power steering. I have recently acquired a IH 384 diesel tractor from a good friend, which will provide me with many spare parts or just an extra tractor as the are both very similar.

After the purchase of the new to me 384, I have learned of the other power steering configuration, along with the dual hydraulic pump configuration.

As I ve read into the dual hydraulic pump operation, I have come to understand that it is likely that my tractor and it s operation requires the dual hyd. pump as the front portion is to supply the 3pt and aux hydraulics and the rear portion of the pump is to supply the power steering. 6 gpm to the 3pt and 3 gpm to the power steering?

As I have it set up now, everything is going into the pump, from the pump to the (Cessna) flow divider valve taken from the 2424 parts tractor to inlet (as stated on the divider valve block); A (as stated on block) runs to the control valve in front of the seat. B (as stated on block) supplies power steering. The return from the power steering then returns and ties into a line coming off the drain (as stated on the block) and goes to the drain hose coming off my aftermarket hydraulic valve. The aftermarket valve is supplied from a hose coming from the port center of the 3pt valve in front of the seat. (In this configuration, I understand that the 3pt supply must be closed in order to use the aftermarket valve, correct?)

Therefore, all the above leads me to believe I need the dual hydraulic pump rather than the standard pump?

Other things I have recognized is the drain from power steering may need dumping into the suction to pump not to drain?

Last question! Should I be supplying my aftermarket hydraulic valve first and the drain to the 3pt valve in front of the seat?

I feel like I am close to potential resolution but need to get some brains in on this. Again thank you for any assistance!

Note* the pictures are showing temporary bypass of the 3pt valve in front of the seat so that I have some use in operations.

first there are no pictures showing. Now I'm not very familiar with those older utility models but I think some of them had a priority valve in the MCV(multiple control valve). I also think you are right about the dual pump deal. Other than that My information is worth exactually what you paid for it.

Thank you for the input. Here are the pictures! Maybe you can provide something further after looking at them.

Well it does look like you either have a bigger pump in some of the pictures or it is a stacked pump set up. In the last picture there appears to be 2 lines running underneath the tractor. Where did they go and what happened to them that they are missing in the first pictures. Other wise I would say it looks like the return or pressure needs to go to the 3pt before or after the remote valve to feed one another in succession. As for working slower that could come from adding more load ( adding more hydraulic functions) to the hydraulics.

Yes, the larger pump or stacked pump is on the 384. The two lines going from the flow control divider and down under the tractor goes over to the power steering cylinder(one cylinder operated where my 424 has two cylinders). As for the two lines coming off the hyd pump on the bigger pump one line is supplying the 3pt control valve in front of the seat. The other line (smaller of the two) is supplying the power steering through the flow divider.

As for the 3pt being hooked up first or the aux hyd valve being hooked up first dont matter so long as they are in succession?
