So, not having an unlimited assortment of large shims with which to shim out the clearance, my plan had always been to just get the bare parts close, and then close up the remaining clearance by tensioning the assembly with a bolt instead of a regular pin. As long as you are only flexing the...

So i drilled the pin holes from a very 'wallered' 5/8" to 3/4 using a stepper bit so the 5/8-to-3/4 spacers would fit. Drilled the washers to 3/4" as well. You can see the drill and a flange-style vise grip with a washer in it on the ground there. Split the spacer/sleeve in two using the press...

That end looked a little fragile to me too, even though the pin brackets weren't really bent in any meaningful way that was hurting function. Still, I put them in the press and bent them back. Then i cut small pieces of angle iron and welded them in as braces. Also bed frame. Then onto the...

So with the subframe itself repaired and.. upgraded..? I dunno, anyway with that part done let's start building stuff onto it. The stabilizer arms (which i always used to call outriggers but im trying to retrain myself) had issues. One was pretty well bent, and both had some issues with the pin...

I guess if my buddy's 3pt cylinder housing breaks i'll have to give him some parts off my parts tractor. I honestly don't expect it to, though. The way i set that link up was under tension. That pulls the round bar on the backhoe subframe against the top of the notch in the mounting brackets...

Next was to somehow connect this blunt-ended turnbuckle to the subframe and tractor. The tractor end is pretty easy because I was able to use the stock top link bracket. That has its limits, but I considered it perfectly good for what i was doing here. On the bottom, no attachment point...

So one of the things i learned from THIS project, out of all the projects i've ever done.. THIS project finally made me realize i do dumb things when i work tired. This project happened during an extremely busy time in my life, which is why it took a year (with long breaks in between bursts of...

Yes! That thread was very helpful in many ways, especially in just helping me gain confidence to take this work on in general. This rehab was not to the extent of doing any machine work whatsoever, but given the tool and experience constraints it turned out well in my opinion. 🤷‍♂️ 😂 Another...

Another small issue with the subframe was divots worn into the round bar where it interfaced with the mounting brackets on the tractor. I welded those up and then flap disced them down smooth. It's not a perfectly round surface but it's a lot better than it was. The inside of the C-shaped notch...

So the order in which i repaired the various sections of the backhoe really didnt make much sense in hindsight. Like i said, i was piecemealing it at first, but eventually realized i needed to take it all down to bits and repair and reassemble it one section or piece at a time. In retelling...

In the process of replacing all the hoses I noticed some extraneous fittings I didn't know the purpose of on a couple of the control valves. After some thinking i figured out those were the flow restrictor assemblies for the swing cylinders. After i noticed that the swing speed seemed to me to...

So the first repair I did upon mounting the backhoe was to replace all the hoses and a fair number of fittings. Here's what one tiny backhoe worth of hoses from Surplus Center looks like. Some fittings were replaced due to thread damage. Of course those tended to be the ones that were the...

So by far the biggest part of this entire project was the refurbishment of the B670 backhoe. Here is how i received it. It was not mounted to the tractor, and one of the main mounting plates was missing anyway, so i was not able to mount it for a bit while we waited for the seller to locate...

New hardware and back to the tractor. I used those same two plated flange nuts instead of the rusty plain nuts that came off, and adjusted the linkage. The rod i had to straighten was bent at the thread and also more gradually along its length because it was misadjusted. Whenever the lever on...

Another thing I had to fix was 'everything about the throttle linkage'. Multiple issues: The throttle pedal shaft was broke loose from the arm it rotates and spun freely inside, thus the pics of the throttle pedal hanging loose way before the floorboard. The inner and outer layers of the...

I finally found all the relevant pics off my phone from this build which started over a year ago.. yeah im that behind. Picking back up from the last pic i posted of the tractor with no fenders on it in post #32... I put fenders on it! The ones that came on it were trash, and the floorboards...

Wish i had noticed this earlier. Oh well.. So, first thing is 'starts well but then runs poorly' is sort of to be expected because the computer is using fixed parameters to start the engine (ie it ignores sensors during cranking other than sampling temp and barometric pressure right before...

Sounds like you've geographically located the issue to a tiny area.. the coupler block thingy! It's just a short matter of time now. I'm not familiar with that coupler block to know how the actual check valves are seated into it (could be not fully seated?) or if they're simply made into it...

Wow, those last pics look like a million bucks compared to the previous fitment. The way that ripper tucks in there with the arm folded, between the teeth of the thumb and everything, is like it was just meant to be! NICE work!

Ever since i heard it said (didnt have to learn this one the hard way!) that you shouldn’t plasma cut a hole that you’re going to run a drill bit through because the plasma hardens the metal, ive wondered if ‘bevelling’ the front of my ripper with the plasma cutter wouldn’t be better than...
