Thanks for all the comments so far. I will try and get over there tomorrow and get some pictures/video to add some clarity to this thread.

Ideally SMs, but both would be nice!

1967 ford 4000 (or is that 4500?) industrial tractor with 753 backhoe. Had several issues but finally up and going and working “mostly” well… but then I have a problem with the swing. It swings very aggressively when i operate the swing lever but it is also very “spongy”… when I let go of the...

As the subject line says, trying to figure out what i have… So 4=4000 50 = industrial 1=diesel 1=no pto F = power shifting. So does this mean I have a ford 4000? Or do I have a 4500?

All of the places selling manuals. Is this copyrighted materials with a portion going to the original writers…? Or is this just a bunch of people that have collected and scanned them over time and are just selling them? Reason I ask is that if these are copyrighted materials I guess I will buy...

Awesome!!! I was wanting to add a gauge to my system (don’t understand why they aren’t on there as standard) and was trying to figure out where to put it, and this is the perfect spot for it. Thanks for all your help with this!!!

I am trying to find some info/cut sheet/maintenance data on a Double A pressure relief valve. You would think with the power of the internet, and manufacturer and part number this would be a pretty easy ask… but alas I have searched and can find no data…. I am trying to 1- confirm that it...

Sorry, in my eagerness to get something posted I did a really poor job in posing the question/facts clearly. I will clear this up now. This is (from the best I can tell) a 1967 ford 4000 series industrial tractor with a 735 (or is it 753) back hoe and front end loader. Again, from the best I...

So I replaced the blown hose on the back hoe, and as I expected I have basically moved the leak from the blown hose, to other parts of the circuit… I have 2 other leaks now, one I have identified the solution, but the other one is at this hose/tube connection. What type of hose/tube is this...

So I finally managed to move the tractor back to my place, and start taking it apart to replace the blown hoses. It certainly seems like whatever that part was it was linked to the auto dig function. It is on the bucket cylinder. As I was taking all of the hoses off to get at the blown one, the...

Thanks for the response, and please excuse my ignorance. I just assumed that there were o-rings sealing the spool positions, I didn’t realize that it was just really tight tolerances matching…. Makes for a whole lot simpler/reliable system though!!! It does make me a little more confused...

Let me start by saying thanks to everyone that commented so far. You absolutely nailed it. Looks like it was for the “auto dig” feature. Odd that it was only on the boom control. I guess at some point it got removed from the bucket controls. The tractor is currently at the sellers location. I am...

So I really could do with some help on this, if anyone has any idea what it is…. I am trying to move this old backhoe and I had some luck today. One of my hoses is blown, and I thought it was the one for the dipper cylinder, but turns out it is the one for the bucket cylinder. So now I have the...

Ok, so it looks like I am taking off two hoses to get at the one that needs to be replaced. While I am in there, as horrible as this job is going to be, I intended on looking at all of the hoses and replacing as many as look suspect. So I know what I am doing on the valve manifold end. I have...

Great idea!!! Thanks for the tip. A lot cheaper than a bunch of pipe caps. Any suggestion about the female valve ports?
