Ford 555 backhoe mount specs

[Mike industrial tractor]

Hello; I have a 1978 ford 555 tractor loader and I wanted to put my backhoe from my ford 4500 on it. The 555 has mounts for a “bolt on” backhoe with holes for bolts and dowel at top.
The 4500 had the weight of the backhoe hung using hooks on the bottom. The backhoe has large round horizontal pins which engage in the hooks.
I am planning to make a 1” plate with hooks on top and bottom that bolt onto my 555 so the backhoe can hang in the new hooks.
Does anyone know where I might find a schematic for either the 555 or the 4500 mounting points to make it easier to design the hook locations? Or even a schematic of the backhoe mounting points?
Thank-you;
Mike

If you have both the tractor and the hoe, measure them up.
Also, check the plumbing at the rear to see how compatible they will be together. There should be a one inch power beyond line that goes from the pump around the left to the rear of the machine to feed the hoe controls and then the beyond goes to right front for the loader control.

Hello; After a long break I thought I would tackle this project again to mount the ford 4500 backhoe to a newer ford 555 tractor loader unless someone near port Huron Ontario may have a 555 backhoe for sale. Before I go ahead with an adapter plate to physically bolt it on, I wondered if anyone may have info on the hydraulics involved.
The 555 may have a higher pressure pump however it does also have a relief valve that I could turn down?
Also are the hydraulics of the 555 setup for “power beyond” which I assume means the backhoe valving comes first and all the oil goes through this and then to the loader?
If so does the valve in the old backhoe itself have smaller openings not designed for this flow rate, which may overheat the oil causing major issues, or are the openings similar to a 555 backhoe?
Also the above maybe doesn’t allow the loader portion to not work properly due to decreased flow because it goes to the backhoe first?
I have the 3 lines going to the back of the tractor but wondered what issues i may face hydraulically.
Thanks to anyone who may offer their opinion.
Regards;
Mike
