- I cut open the diesel fuel tank on this Dynahoe 160 backhoe to clean it out and remove sludge and sediment. Afterwards, I weld it back up and start the engine to make sure the fuel system is no longer clogged.

You really need to get a clear full face safety shield so if grinder blade explodes you dont cut your face to pieces.Eyes as well. Great job!!!!
I was taught to weld an insert like that by welding one half complately, then the other half. Start on the center of a string, weld towards the corners to relieve stress. Also, move your body so the grinding sparks go away from you, not towards you. I have caught my sleave on fire not paying attention to that!
Thank God that's a diesel tank, with all those sparks and fuel dripping. Could've been ugly.
Love your show. It feels like we're learning together.
Interesting how you are worried about lead paint but happily use the grinder without a guard.
He's wearing enough clothing to the point where it probably wasn't much of a concern. I doubt any sparks made it through that sweatshirt.
@@AManOnline. the disc will make it through his fingers if his hand slips
Impossible to cut anything resembling a straight line with the guard and the handle on. Those are for grinding applications only imo.
I'm not an expert, but I have a few suggestions to add for anyone cutting with an angle grinder: 1. Use a diamond cutoff wheel. Less disc material to inhale and lasts longer. 2. Cut in a direction that sends the sparks away from your face, not towards it. 3. Wear a face shield or welding helmet when cutting & grinding. Auto-darkening ones have a cut/grind mode for exactly this situation, and while safety glasses protect your eyeballs, it's no fun getting pelted in the cheeks and throat by hot metal.
Worth mentioning to anyone wanting to try a cutoff wheel on a fuel tank... DIESEL ONLY. Don’t try this on a silly gasjob with it’s dangerous recreational fuel!! 😂
Yes, that's a very good point!!
Glad you mentioned that...may have saved someone's life.
@@2002southzone sometimes I wish gasoline was treated like racing fuel - specialty shops/distributors only, and all cars bigger than a Miata were *mandated* to be diesel!! (And Miatas are mandated to be manual. Lol)
Yes, gasoline tanks are dangerous even if emptied and appear completely dry. The only way that this may even be attempted with gasoline is with a fully cleaned and rinsed tank then completely filled with water. Either way, don't bother with a gasoline tank.
@@esqueue filling it with argon will also work.
It would of been nice if you could of made it a see through bullet proof glass 🤗
I Just looked this same backhoe that my partner has and thinking about buying it. It is running now he said but has issues with alternator not charging and no breaks, THANK YOU SO MUCH FOR DOING THESE YouTubs.
Oh nice, you should buy it! I think these came with a Delco 10DN alternator which can be hard (and expensive) to find, but I just replaced mine with a 12Si and it works fine
Just an excellent video , thank you , great it all went straightforward this time !! Welds spoke for themselves , just the brakes left can't wait to see how you manage , not sure on set up on these , no dowt you will tackle it without question , thanks again great stuff
Thanks, Steve! Hopefully the brakes won't take too long because I really want to get this machine into service!
next time you need to clean the inside of a fuel tank, try using some Chemtool. let it soak for a day... amazing stuff. great work.
Thanks for the tip!
Muriatic acid works good to, soak overnight, flush out with water several times, then fill immediately with fuel and I like to add a bottle of marvel mystery oil, that will keep it from flash rusting. Downside is you don't want it to sit for any length of time not full or it will rust again, if I were to open one I would definitely use redcoat
@@theangrytruckerchannel359 yep, muriatic acid woulda cleaned that tank right up like new!
young man , you got my respect, you have common sense and you work hard. new sub here, curious what do you do for a living ?
Thanks for the sub! I'm an engineer gone full time CZcamsr
I can also agree with everyone you have what they don’t seem to teach anymore, common sense !
@@Chiefbuzzbee common sense can't be taught. I've met lots of book smart degree holding fellas that couldn't figure out things we take for granted.
A nice clear, concise, top quality video - thanks. An idea/suggestion for any tank cutting/welding: first fill with water to remove all the residual gases.
Thanks for making this video! I had the same idea for my old sludgy diesel tank but seeing you actually do this is awesome and gives me confidence.
Mmmmmm think I mite have cut a hole near the top as for one u would be less likely to have to deal with a pin hole that contains to bug u ...I would have done the same tho cut a hole into it to clean it ...just wondering why u cut the hole at the bottom 🤔
If I had to go back and do it again, I'd probably just remove the tank, which would let me empty out the tank without cutting holes. I didn't realize at the time that the tank is removable because it wasn't immediately obvious. Oh well! 🤷♂️
Taking that old tank off probably would have been harder that what you did, I think. I agree Nigel, you could have made a nice inspection port on the top, like they do in boats. (Just about to dive into the assessment of my sailboat’s integral tank. Was looking for a good video that shows the inside of a diesel tank. Thank you!
You ground on that thing when it was already tacked in place? Pretty sure that filled your tank with ground up grit and metal. I haven't watched to the end of the video yet to see how it worked out, but I sure wouldn't have done that.
Hahaha Google grinder accidents 🩸🤦♂️
Did you not bang out the dent in the bottom first???
Was question as well
I think you should paint a bandaid over the weld area. 👍
Didn't know you could weld on a diesel tank without filling it with water first to displace the fumes. I know diesel isn't gas but still. Safety first.
Just discovered the diesel tank on my Lull telehandler is very nasty at the bottom. Whole fuel system is grimy and filled with rust. For some reason a filter/separator was not included with the Cummins engine. Very surprised. Nothing seems to have been removed. Just ordered one along with new lift pump and other hardware including new fuel hose. I've resurrected diesel engines from the dead before. This one is still running so I think everything will be OK. I might actually use your method as my tank already has a pinhole leak in it that needs to be addressed. It actually has a drain plug in the bottom so will probably drain the diesel, fill with water to displace fumes, drain it, cut it open, clean and finally weld it back up.
Did you wipe out the tank after grinding cheers
Woefully late to viewing this Dynahoe 160 series of video’s, but I have heard that when welding on a fuel tank.., pipe in exhaust fumes in from the filler neck while doing the welding…, no Oxygen, no fire.
Why not try to fix the dent in the bottom of the tank while you had it open?
Did I miss you beating the drain port back down as the lowest point of the tank?
I think I would of used a long handled brush, rinsed a few times with a garden hose or even diesel , pumped out with @ harbor freight 12 dollar 😊😅battery powered fuel transfer, maybe use a magnet
I notice you didn’t clean out the grinding dust out of the tank before you weld the plate back also the penetration the welding will be Blasting steel into the inside of the tank when you wielding, Have you ever looked at the inside of a plate after world in two together the mess that comes off the back of the steel that’s now on the inside of your tank
I was wondering that too.
Nothing a fuel filter can't handle.
He most likely did, probably just edited it out. A lot of details that you would think you would include he edits out.
Curious why you cut on the side instead of the bottom. Could have put an inspection plate there. Your four-legged friend is beautiful!
Probably the dumbest question bit what about explosions or fire while grinding and welding a fuel tank? I know diesel takes a lot more heat than gas but the question did cross my mind. Can you explain so I can add that knowledge to my tool box please? Love your work.
No, not a dumb question! Diesel does not explode like gasoline fumes can, so there's little risk there. I also flushed the tank first, and I had a fire extinguisher handy, though it was out of frame 👍
@@WaldosWorld so purging still needs to be done before grinding on it? Last note how did you fix the concave dent in the bottom? Or did I miss that part?
@@chescabler2659 I don't think he fixed the issue. At least not on camera. (-;
I feel like grinding with the large gaps could potentially have introduced metal bits back into the clean fuel tank. I'm not super mechanical though so maybe it's a bad observation. Anyway, nice work. 🙂
Aren't you draining the tank first to get most of diesel out?
lol..try flipping the angle grinder over so you don't get a face full of sparks while you cut...
You forgot to tell the audience that you filled tank with water to brim before cutting. Otherwise someone could get the idea that it's safe to cut tank with fuel and fumes in it.
You are a brave man sir
I took more safety precautions than what was shown on camera. Also diesel isn't particularly dangerous compared to gasoline 🤷♂️
from the Netherlands thanks for the video
good work but your are showing the tank inside after cleaning??
I even said "can we see?"
Ah yes the joys of diesel fuel.
I.e. it not blowing up.
There’s a drain so flood water from the filler and let it drain out ,any fuel can explode,be safe!
The bottom of the tank is dented up and cant be drained properly. Obviously diesel wont blow up or he would be blown up.
EPA entered the chat
Should have taken a few minutes to bang the dent out of the fuel tank to make the plug the lowest part of the fuel tank before closing up the hole.
You really do go for it, I tip my hat to you sir
Can't you use a plasma cutter?
Nice work keep the great videos coming
Thanks! Lots of good stuff coming up!
I WUZ waiting????????? 💥
Just KIDDING !!
GREAT JOB !!
8:50 Runs better when grounded!
Aspen looking beautiful as usual , digger cool too
Love the video, and that Vizsla, had 4 of them, amazing dogs.
Wear a proper face shield! When cutting discs disintegrate, shards shoot out and into your face at high speed. Ask me how I know!
Hello Waldo. I was wondering if you possibly knew why there are two hydraulic pumps on the backhoe. Is one for the front hydraulics and one for the back?? Also, my hoe has a toggle switch on the lever for the front bucket. Would you happen to have the same thing? If so, what is it for?? Thanks
I think the front hydraulic pump is the main hydraulic pump for the loader and the backhoe, while the rear hydraulic pump is probably for the steering and/or the hydraulic assisted brakes.
The toggle switch on the loader lever is to selectively brake either the left or right wheel for tighter turning.
A question regarding the rear pump. If the brake system has a master cylinder, it doesn't need a pump, right. Because the break system operates off brake fluid, not hydraulic fluid. Also, what are the positions and their relations of the toggle switch to know what it is set on? aka right/left/both working. Thanks. And thank you so much for responding as quickly as you did. Also, what hydraulic oil did you use. Is there a weight to look out for? Thanks again.
Yes, the brakes use regular brake fluid, but some models (mine included) have a hydroboost unit which assists in applying the braking force needed to stop the machine. The hydroboost unit works just like those found in 3/4 and 1 ton pickup trucks; it takes hydraulic pressure from a hydraulic pump and converts it into mechanical force which it applies to the brake master cylinder.
As for the toggle switch, forward brakes the right wheel and backwards brakes the left.
For hydraulic fluid, I've been using Traveller Premium universal trans/hydraulic fluid from Tractor Supply. It seems to work fine.
Thanks for helping me out. I hope you don't mind if I ask you any other questions in the future through this video. Thanks
So not a lot in there! NEXT!
Hello Waldo. Can you tell me what batteries you use for your dynahoe. I need to replace batteries but don't know what was in there originally. There were two, I believe. Thanks
The machine didn't come with batteries when I bought it, so I don't know what it's "supposed" to use, but I have two Optima red top batteries in it that I had lying around. It's a 12 volt system, so they're wired in parallel. If I were you, I'd just go to Walmart and buy two of the biggest/cheapest batteries they have.
@@WaldosWorld ok. Thanks
Get the highest cold cranking amps you can
Diesel fuel filters are there for a reason.
You might want to use a face shield like the weed eater guys! Lots of schrapnel flying. Nice video!
Are you going to make a door for the dyno ?
Nice
Came here to see how to clean out a diesel tank and walked away with a grinding and welding tutorial 🙄
Whats the capacity of the tank?
i don´t get it, you made so much effort cleaning your tank, but did not protect the inside of the tank with tank-epoxy-protection-solution. A bigger draining whole with plug underneath your tank would be a nice to have
Man, I am not the safety police but you REALLY need to put the grinder guard on and a face shield or welding mask. If that wheel explodes, your going to get impaled....dont want to see that happen. I cringed the entire time.
Watch this guys video and see the graphic images at the end. Should scare you enough to do it ;). GL

Looked easy. But probably took hours.
It actually only took an afternoon! The video/thumbnail editing probably took longer 😂
Waldo's World keep the videos coming; looking forward to the next one.
Will do, there's some exciting stuff coming!
I recently built a backhoe from Lego , does that qualify as engineering , by bf laughed when I said so 😥
I would have installed an inspection hatch for future servicing.
I'm not knocking his process it just was not maybe the most efficient. Understand there parts laying in the bottom. Grinding and sparking fuel tanks is not so good. No fire extinguisher not so good. I hole saw in the bottom would have allowed to wash tank out from top. Weld a threaded cap port in for future cleaning. Anyway Waldo's world wins
Would've power washed the shit out of it and resealed it with something before patching it up.
I would love to give thumbs up, but I was a little surprised that you didn’t use anything to catch up the old diesel or water. What about environmental issues?
i would have just power washed the tank from the top you would get everything for sure
you know the earth is flat right?
FYI use cut off wheel with sparks shooting away from so you don't cut metal in your clothes hair and face ..... believe I know😒
In all honesty, I'm getting pretty tired of "CZcamsrs" that are good at filming and editing, but have no idea what the hell they are doing, though love to show the world their techniques. Wear proper PPE (especially a filter mask while grinding), put the damn guard back on your grinder, and bevel your edges BEFORE you tack the plate into place. FFS
Isn't it potentially highly explosive to use hot cutting gear or welders on fuel tanks? Well at least you didn't blow yourself up.
Id be scared asf grinding on a fuel tank
Should have made yourself a removeable plate so you can get in there again if ever need be. Oh well, just chop it and weld it back up again... That lower fitting is where I found the pine needles stuck in the fitting that cause a sporadic fuel loss and stalling issue, drove me NUTS!!!!
