That was my thought. I've been looking for the manuals online, service, parts, operators. But everything I find is for CK's and the case dealer is telling me that's not the same machine.

If I can't find a plug, or a better idea, I may just drill it, flush the heck out of it, fill is with inert gas, and weld a drain plug into it. That seems a little drastic though so I am hoping for a better option.

I wouldn't drill a hole in it and hope you could get a leak free weld especially with the tank on the machine. You probably have to take some stuff off, maybe a lot of stuff. It's not going to be a simple job getting this machine fixed and running. I'm sure you're going to be using a lot of choice curse words. That's why a lot of people don't do restorations on old machines left for dead.

Shimmy, thanks for explaining what you meant.
No problem , No worries.

NMBlackBetty; your 780 is a CK =——>780CK.
There should be a petcock on the bottom of the fuel tank.
if there isn’t remove the fuel line from the shut off valve on the bottom of the tank and remove the valve.
You can avoid a fuel bath by hooking a shop vac onto the fuel filler tube.
here is link to the Construction King section of the Case on-line parts book.

Thanks! When the sun comes up I'll go give it a try. Plan is to drain it out, filter it, then use a transfer pump to spray it back through the tank until debris stop coming out.

Another option on the fuel tank would be to make one of @willie59 famous 'suck bucket'. There is an entire thread on this handy shop helper somewhere in the forums. Basically a spare 5 gallon bucket with lid that has a pour spout. Get some vinyl tubing, drill a tight hole through lid for vinyl tube to squeeze through. Apply vacuum via shop vac to pour spout, insert vinyl tube into whatever needs sucking up. Quit extracting fluid before suck bucket gets close to filling so it never goes into your shop vacuum.

I read about it here some years ago. I've used it to suck out hydraulic tanks, fuel tanks, etc where there was no drain point, or where the drain was blocked up due to debris in the tank. The advantage is also being able to suck out a fair amount of chunks in the process and start work on the cleaning process. I used ⅝" tubing and inserted a piece of ½" copper tube in the end for a wand that can be forced around and do some light scraping.

And yeah, stupid is right. Ego's are expensive to have.
His truck is going to be on the road, both before and long after this backhoe is. (He drove home and is probably puttering to breakfast in it right now). Was it dumb to haul your backhoe- sure was. But so is trying to put this backhoe back together.

If this backhoe was 20 years newer with minor problems, and a more popular model, I'd be all for spending the $$$ to put it back together. But you're going to spend the same amount of money and time putting this back together, as you would fixing a good machine.

But I suppose its a better and cheaper hobby than hookers and coke, so by all means have at it. But I don't think I'd be so excited at pointing fingers, over other peoples blind spots in decision making. Because this backhoe's got dumb written all over it.

Don't be so hard on NMB.
He said earlier in his thread that he is restoring the 780, not because he needs a T/L/B.
But because his hobby is restoring what other people call junk.
He said that he already has 2 or 3 in running order.

We all have hobbies. If his hobby is tearing down and rebuilding trucks, equipment, whatever than so be it. Is it smart money, of course not but I am sure he already knows that.

In a past life I restored several muscle cars. I found pleasure in hunting down parts, almost more than actually working on it.

I like watching other people do these projects so I look forward to progress posts.

It's kinda like Ford N series tractors. People spend several thousand bucks to restore them and they still aren't worth much or all that useful when they're done. But they enjoyed the project so it was worthwhile to them.

I hope this negativity doesn't discourage the OP in any way as the view is not equally shared amongst the masses. Doesn't really matter if one supports the endeavor or not as they are not financially contributing to the cause. The OP has only asked for advice and guidance at this time that I read into the posts. Obviously serious in the preliminary interest as expended the funds to move the machine to another local to make it easier to work with, or on.

The way it was moved? Certainly not what I would have done. Given common sense not being so common any longer apparently applied, the contract trucker has to deal with the final outcome, or damage incurred to his equipment.

Going to be an interesting project to watch unfold as I had basically the same machine. It was a powerhouse but didn't fit my needs upon project completion so was sold.

I for one am looking forward to the "overload of the week" video.
It is all part of the user experience of this backhoe.

Whoa nellie. I ain't the voice of dismay and gloom here. I'm just going for a splash of sanity. A sunbeam ray of reality if you will.

So far I've read tales of repowering, rear axle removal/replacement because we want a locker, numerous custom suspension seat options, and now we're up to tracks. If we put rockets on this bitch we could launch satellites.

What we are going to end up with is a 2wd heavy ass backhoe, in the sands of new mexico. There's a reason it got parked in the weeds 20 years ago, and its not only related to the engine issues.

If it was grandpa's backhoe that saved the family from starving in 1962, sure, its got memories burned into the iron. But I'm looking at a minimum of $10-15,000 in hoses, cylinders, engine work and tires, Party on.

And we'll have the next five years to watch from the sidelines. Should be fun.

Whether or not it gets back to working condition is yet to be determined. Who knows why it was parked but the engine being the problem seems to be the most likely. The OP has it home where he can better evaluate what all it would need to get it back in working order. Maybe the only major thing it needs is the engine rebuilt. Hoses and cylinder seals, etc. would likely need attention on any older backhoe or any hyd. machine for that matter so that's a wash. There's no way to know what all it needs without looking deeper into it. Then the OP can decide if he wants to proceed.

It's a big machine which could explain why it wasn't as popular as 580 size backhoes. Dynahoe and others had some big heavy 2 wheel drive models as well. They were the preferred machines back in the day for tough conditions. A 780CK could be great for digging stumps or lifting heavy loads. A backhoe loader is a very versatile machine for a variety of things.

I have a 780CK .It has cost me about 1500 in hydraulic hoses and another 1000 for a radiator.I did the brakes and cleaned up the air chambers but i need a new mount for the compessor.I did some work with it and am now considering a rebuild on top end at least cause shes blowing white smoke.Also the hydraulic fluid is leaking into the tranny and going out the breather hole on top side of trans.If you need info i could help probably help but i know that Tinkerer is a good guy and has helped me.Good luck

And this is a perfect example of what happens when someone walks in on the middle of a conversation and has no context for what's actually going on. Glad to see this forum isn't immune, I see it everywhere when conversing in this format.

Amen man. I'm $130,000usd into a 2006 ford F350 extended cab long bed over my last "hobby build". I could have bought a 2024 F450 platinum with every option for 3/4 or less the money. But Damn is that 06 fun to drive and lord does it drop jaws when people look under the hood and under the truck.
