Cleaning the INSIDE of a Diesel Fuel Tank on a Backhoe [Dynahoe 160 Part 8] 

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

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!

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!!!!

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.

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.

Interesting how you are worried about lead paint but happily use the grinder without a guard.

Nice work keep the great videos coming

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.

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.

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.

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!! 😂

from the Netherlands thanks for the video

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 🩸🤦‍♂️

You are a brave man sir

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.

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 ?

Did you wipe out the tank after grinding cheers

It would of been nice if you could of made it a see through bullet proof glass 🤗

Did you not bang out the dent in the bottom first???

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 🤔

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.

Nice

Love the video, and that Vizsla, had 4 of them, amazing dogs.

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.

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

Ah yes the joys of diesel fuel. I.e. it not blowing up.

Why not try to fix the dent in the bottom of the tank while you had it open?

Are you going to make a door for the dyno ?

8:50 Runs better when grounded!

I think you should paint a bandaid over the weld area. 👍

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!!!!

lol..try flipping the angle grinder over so you don't get a face full of sparks while you cut...

Curious why you cut on the side instead of the bottom. Could have put an inspection plate there. Your four-legged friend is beautiful!

EPA entered the chat

There’s a drain so flood water from the filler and let it drain out ,any fuel can explode,be safe!

You really do go for it, I tip my hat to you sir

Whats the capacity of the tank?

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

good work but your are showing the tank inside after cleaning??

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.

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

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.

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

I WUZ waiting????????? 💥 Just KIDDING !! GREAT JOB !!

So not a lot in there! NEXT!

Diesel fuel filters are there for a reason.

Aspen looking beautiful as usual , digger cool too

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.

Wear a proper face shield! When cutting discs disintegrate, shards shoot out and into your face at high speed. Ask me how I know!

Looked easy. But probably took hours.

Would've power washed the shit out of it and resealed it with something before patching it up.

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 ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-oJRSkBSb5S8.html

You might want to use a face shield like the weed eater guys! Lots of schrapnel flying. Nice video!

I recently built a backhoe from Lego , does that qualify as engineering , by bf laughed when I said so 😥

you know the earth is flat right?

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

Came here to see how to clean out a diesel tank and walked away with a grinding and welding tutorial 🙄

I would have installed an inspection hatch for future servicing.

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

i would have just power washed the tank from the top you would get everything for sure

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😒

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?

In all honesty, I'm getting pretty tired of "RU-vidrs" 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

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. 🙂
