AT LAST! Completed the Farmall 504 Loader Hydraulics (Pics)

This has fought me all the way. Obviously the engineers at IH did not plan on many loaders to be installed on the 1962 Farmall 504. Intergrating additional hydraulics and trying to make it look good was a challange. This is the happy medium between function and form.

I brought the intake from the pump to the valve. It leaves the valve through the power beyond port and goes back to the power steering flow divider. The out or relief port goes to the fill plug at the IPTO. The fitting I replaced the plug with is a 1 1/4" ORB x 3/4" MJIC, 90 degree, try to find that at NAPA. All feeder hoses are 3/4", work hoses are 1/2", fed off of a fresh 17 GPM pump running at 2000 PSI. The loader is faster than some new tractors I have used.

Enjoy the pictures... Sorry for all the dust, just baled about 160 round bale from the 3rd cut of the year.

Thanks for help from all of you. Especially Allan for saying it cannot be done without a PTO pump and reservoir to inspire me (LOL). I hope this can help someone later down the road.

Doubt if I said it "couldn't" be done; probably meant that a PTO pump would have been 100 times easier. :>)

Allan

Definatly will not be getting on and off that side of the tractor.

Wow that seems like a lot of work, especially if you need to pull the loader off with any frequency. I'd just plug the loader into the built-in valves on the tractor and be done with it.

You can slip a pto pump on pretty darn fast. Will have better performance also.

In my humble opinon Charles has done it right! Have you ever tried to use a pto implement with a pto pump installed? I have a Oliver 88 with a farmhand loader and a pto pump. (Hate to disagree with you Allan.) I plan to install a crankshaft driven hyd. pump so I can have my live ipto back when I need it and still use the loader when I need that. You can never have too many hyd. valves(I have a farmal M eguipted with a loader,hyd. bucket,&grapple and a 3PT. hitch and I have 6 hyd. valves. If I put the fork lift on the 3PT. than I am using all 6 valves. Armand

I am glad ya'll stopped by to read this. I worked my A** of on this project. Allan, I agree the PTO pump would have been easy. But what fun is easy

Someone mentioned the removal of the loader. If you look closely I used Pioneer QD couplers on the 3 spool valve. All I have to do is cut the ty-wrap holding the 4 lines in place and unhook. That is why I have the slack looped. I cut the lines about 65" long. Also (look close) I used 3/4" quik couplers on the supply and return lines. I can remove the ENTIRE pedastal and valve bank, hook the two lines into themselves (one male one female) and remove the return to the IPTO. I have the matching pairs with plugs installed to keep out debris and such 8)

I agree with Armand, you can never have too many remotes. That is why I have the 3rd spool. My father has 5 on a Ford 6600. Two for the loader and 3 for the 15' bat-wing mower. He is planning to expand it to 6.

As for performance, It is fast at idle, it is fast at WOT. Dad could not believe how quickly it would open the bale chamber door on his 504C Vermeer. 17 GPM is a lot of oil, most new tractors in this HP class only have 10-12 max. The old girl is running and operating better than it was 30 years ago. His 6600 has 1/2" supply and return lines, 3/8" work lines. I am using 3/4" and 1/2" respectivley. That makes a difference.

Thanks again and enjoy,

Charles

PS: My wife has informed me recently this is an expensive HOBBY! I know, and my next one is going to be an 06 or 86 series 90-120 HP!!!

I hope it works well for you! I think that as plumbed, if you were to move a loader remote while turning the steering wheel, you will lose steering assist.

I see why you plumbed the priority valve that way (less restrictions and full flow to loader), but i think that you may end up changing the plumbing maybe even adding an aftermarket priorty valve with larger ports if the steering issue occurs during your normal uses.

Karl, I thought about this for a while. Idealy I would have came off the divider, then to the loader, then to the remote manifold. It involved a lot more work and I would have had to make some new steel lines to make it fit properly.

The way I plumbed it was easiest as far as convienance goes. I have not put a load on the loader (pardon the pun) and tried to steer. I am sure I would loose some if not all steering while a loader spool is shifted. Most of the time one is not steering and using the loader. If it becomes an issue, I can install a secondary priority flow divider as you mentioned. I think they have them in Northern Tool.

I figured someone would find the flaw in the system. I knew that I was giving the system hydraulics a backseat to the loader but I had to do it this way to get above the 1600 psi relief in the remote manifold. This way I have 2000 psi at the loader, then feed the rest of the system with lower psi.
