Can I eliminate a diverter?

[montejw]

Hi, I've been lurking for 6 months or so, just bought an AC 5020. It has a manual diverter, selecting either the 3ph or fel. I've already removed the fel once, disconnecting the fel control QD's. I didn't loop them, but fortunately I had the dirverter set to the 3ph. I looked at the 2 hoses for awhile and figured I better loop them before something bad happened.

My question, can I eliminate the diverter? Would the 3ph have to be plumbed last in line on the power beyond circuit of the fel control? I would also like to eventually install a hyd. top link and side link, again would the 3ph need to be last?

Since everthing would be in series, only one circuit would work at a time. Is there another way to do all this in parallel so more than one circuit would work at any time?

Thanks,
Monte

The open center hydraulic circuit must have all valves connected in series. If you connect them in parallel the fluid will take the path of least resistance meaning you would never get a valve to work.

Do you want to activate the 3pt and loader simultaneously or do you just want to operate them without manually operating a diverter?

Operating in true simultaneous mode is not very useful or practical in the real world but can be done depending on the internal design of the loader valve. The 3pt, being the last in line, will get whatever flow is left over from the loader valve.

The real question is if you want to operate the valves without dealing with manually changing the diverter. If so, then connecting everything up in series with the 3pt being last, you should have no problems. Plumbing might be an issue but I am not familiar enough with you tractor's configuration to hazard a guess on what the issues may be.

Normal series connection order would be pump to loader valve to any aux valves to the 3pt then back to the tank. The loader and aux valves should have power beyond capabilities for best results. The 3pt being the last valve in the circuit does not have power beyond as it exhausts directly into the tank.

Yes, I want to be rid of the diverter so I (and my wife) don't have to make the switch. I was just doing some work on the driveway with the box scraper and loader, scrape some, load it and move it, it was a hassle to constantly switch back and forth. If it's not too much work to replumb, I'll do it. I just wanted to know if what I thought was even possible. Might be a bit of hose here and there, but if I can keep it clean it'll be worth it.

The tractor is just a little 24 hp with an FEL. It's an Allis Chalmers 5020 or Simplicity 9523 depending on stickers. It's an '80 model with less than 800 hours so I'm hoping to get some use out of it.

Thanks for the help,

That being the case, just hook everything up in series like I explained above. That's how it's done for all other tractors. This will give you the flexibility that you need.

Was there a reason for the diverter in the first place? To me it seems more expensive than just putting the loader valve and 3pt in series.

It's the way it was when I bought it.

monte,
My father has a 5020 and I have always wanted to put a small loader on it. I have asked a few loader makers and they indicate that they don't make a loader for that tractor. Mind if I ask you what brand loader it is on yours and where the tap for the hydraulics comes out. I see a pipe plug under the seat on the right side that looks as if it is pressure. Afew years ago the right side hub lost the bearing and broke the housing ( seems to be a weak spot on these tractors )
I am presently running it with out the right side drive shaft ans u-joint until I can get another gear cut for it .

There's a block on the right side just where the pressure line (small one) is attached to the trans housing under the seat. It has 3 lines attached to it, the top one is high pressure going to the diverter, the lower front one is from the "OUT" on the FEL control valve, the rear one comes from the diverter and I assume it's high pressure to the 3PH.

The loader is an Allis Chalmers model #430. It's detachable, which is cool.

thanks for the photos- I will have to compare in a few days to see what I have, as the tractor is at the farm and I am working in order to have enough money to keep ranching.ha ha

If you can take some pictures of yours that would be great. I'd like to see the area where the pressure line from the pump enters the trans housing.
