I needed a break from working on this machine after finishing the pond, but now I'm ready to dig in and make her right. Let's see what we find inside this fuel tank...

even if you overpaid you know you have a reliable machine you have gone through yourself now
That looks like a decent planer, the feed tables are interesting. I couldn’t see any snipe there.
@@woodcox0171 i was thinking the same thing, couldnt see any snipe.
It had some snipe, but not too bad. Agree, it seems a decent planer for a crazy low price.
@@toeknee5464I second that 👍
wrong kind of magnet for woking thru the tank, you'd want magents with the polses fairly far apart, but also wide poles, so they have more flux than the sheet metal itself will take up. Those pot magnets have poles very close together, so excellent hold, but very little "penetration" so to say.
A wild Mattias appears!
Makes sense. Good to know, but at this point I hope not to need them anymore! 👍🏻
Indeed
“Watch Wes Work” used the term “perpetual content generator” a few days ago to describe a Massey Fergusson Backhoe. You have good taste if you are also watching Wes and borrowing his witticisms. I feel the original exhaust stack was clamped to the muffler flange and not the bonnet flange and was a smaller diameter. It would be very unusual for the stack to mount to the bonnet flange. Your exhaust smoke is black rather than blue, which indicates unburnt fuel rather than burning oil, which then implies to me that your rings, pistons and barrels are okay and the oil use is more likely to be valve stem seals and that your injectors may need overhauling instead of an engine overhaul. That is going to be a great little tractor by the time you’re finished. I am really enjoying these videos.
It wouldn't matter how far the poles would be apart you would never get sufficient flux
Hi John to remove the track, remove the grease fitting and back the idler wheel back then remove the tracks.
I don`t get jealous very often but I think I am quite jealous of this guys cool demeanour & ability to fix & improve everything.
You can release the grease out of the tensioner and use your excavator to take the track of so you can take the idler off and fix the rail
I never thought that I would find watching someone getting sludge out of a diesel tank interesting but I found it compelling.
they make a nozzle for your pressure washer that's for cleaning out fuel tanks it's got little slits around the ball that spins and you can put that down in there and clean all of that out
34:15 - I work for a paint shop that's been doing (among other things) Caterpillar machines for 40 years, and I can confirm that 'Cat Yellow' has changed over the years.
John is forgetting the hidden value of "Endless repair video content on KZhead"
When an FC101 video starts with a sigh you know it's going to be an interesting one!
9:06 "It's probably fine for sparks to be flying around in this fuel tank, after all, it's just diesel, but I am going to fill it with water anyway" -- The man who caught his man lift on fire with torch metal and old oil 😂😂
As a retired machinist and all the time in the world to play around, I would definitely recommend fixing the guides properly. But then, I'm sitting in a clean, comfy armchair eating Doritos and watching you bust your back for my viewing pleasure. I like the outro music. Appropriate. Thanks for your content.😊
"Watching his videos every week is like that meme: 'I don't want peace; I want problems always.'"
FYI Bottle jacks many of them will work on their sides if the pickup is on the bottom. Since it looked like you were working on pins. I actually made a portable press using thick steel plates and multiple pieces of all thread, and a jack.
That Dozer has had a neglectful life. But it has a good Daddy now, that's going to make it whole again.... That's awesome.
Dear John! Ther is a solutin to your spraycan disaster: Turn spraycan a 180 degrees pull trigger untl it clears, so it clear the nozzle - put in storage. Greetings from AUSTRIA/Vienna.
When you are done using a spay paint can turn it upside down and spray till no paint comes out then you are good for next time you are going to use it ❤😂
After the past challenges with the fuel system, it was so satisfying to see all that guck removed from the fuel tank. 😎👍
48:55 you found the most positive way to lock at that dozer (Imo). It does not work perfect, but your relentless struggle and dedication to getting it running well really drive the emotional investment I have in your videos.
Make no mistake, Jon, I am SO GLAD you bought that dozer!
You've inspired me to do the same for my 1996 excavator tank with all the same problems! I just don't have all your tools 😂
Think positive - had the dozer been flawless we would not have had these interesting videos!
6:41 Jon, the flash on your phone is on.
This video made it seem like the fuel tank was just an afternoon fix vs the multi day headache you had trying to start the engine, cleaning filters, replacing filters and jerry rigging an inline filter.
Quick tip on spraying with spray cans. When you finish using it, invert the can and spray until paint stops coming out, this clears the nozzle and stops it from blocking up, so it's ready for next time.
That used to work. Most of the time now (in my experience) they still spray upside-down.
Agree. I always do that but I also let cans sit for years and then complain when they don’t work. 😂
Does not always work as I have had cans run out of air and still half full of paint, especially when its a touch up can that you use for many small jobs over the months.
@@incubatork Theres a channel called 65 ford, he showed how to repressurize any aerosol can that has gone flat. Video is prolly bout 3-4 years old but still good info if you're interested.
65 Ford is just as great a channel as Farm Craft! He is one heck of an engineer
That metal cutting saw blows my mind. Goes through like butter
Every time you're done with a can of spray paint, but there's still some left - turn the can upside down and spray a small amount until it comes out clear. This will keep the nozzle from clogging when the leftover paint dries.
you cant do that on a lot of the newer cans, they are designed to paint in any orientation (or so they say lol), =(
Came here to say this but figured someone already had.
Great video John: I'm surprised you didn't attach a piece of flex hose to the fuel pickup at the bottom of the tank and attach a float to the flex hose end so you would draw fuel from the relative top of the fuel level rather than at the bottom of the tank. I think this would eliminate any possibility of bottom feeding sludge and water and crud in the future IMHO. 🙃
love the context generator because at the end of the day you know what's up with your machine which last till the end of days. we love your videos 1 hour 2 hour what ever we will watch you.
John, When you have completed repairs, you will have a new Cat dozer !!! The challenges that you have solved are amazing.
Great content no stupid background music, nice work and really worth spending 1 hour watching, keep upload good job 👍👍👍
I'd put those track frames in the "run until it explodes" category!
Your willingness to tackle these projects AND share it with us is inspiring. Can’t wait for the next one. Is there a Vevor link? Thank you.
Just added to the description.
Awesome video. American ingenuity on display. Caterpillar never thought anybody would want to clean out that tank.
"Shimming the Idlers" was the name of my 90's alternative rock band!
Blimey that tank was dirtier than my browser history! No wonder it was clogging filters so fast. That was a great solution cutting an access panel next I loved the bottomless box when you were spraying 🙂
John your our master of repairing just about everything...sometimes old paint cans can be revived by soaking the can in a bucket of hot water then shake like a mad man
Really excited to see the next video! You’re a brave man. Soon it seems like you’ll have a fully restored machine.
“shocking that that leaks” Made me smile.
After you finish the repairs you are doing, it will be better than it came from the factory. You will greatly increase the sales value later. A great job, yes sir.
Concerning the drain valve: take one of those magnets with the eye loop, place it above the valve lever, then take a zip tie and hold your valve lever in closed position.
You have definitely helped and improved the performance of that Cat
I enjoy it when any body takes old equipment and fix it up, well done.
That dozer has certainly been good for YT content!
My YT content generator!
Another great video John. In my 40 years of diesel experience compression tests on a diesel are not necessary. If a diesel has low compression white or gray smoke out the stack and excessive blow by will be present. You can temp gun the exhaust ports at idle to test cylinder contribution. Check the intake and exhaust sides of the turbo for possible bad turbo seals. Most large diesels from that era just used a lot of oil.
John, when I was in the Army we used to "purge" fuel tanks on those M60 fuel tanks by dumping a whole bottle of dish soap in the tanks and sticking a hose in and let the water run till got all the soap out. Those bubbles would pick up all the loose particles and float them out. Something to think about.
That sodding thing had it coming. Must have been dispiriting to think about all that time you took fixing it on the pond job, knowing now that it was never going to help you out. Satisfyingly done.
I’m very grateful to you John for putting out these videos every week. I so look forward to them because they are the perfect combination of interesting, educational, entertaining, and motivating. Seeing you tackle jobs gives me encouragement to take on more of my own. How you manage to do all this AND make a high quality video marvels me every time!
Hey John, I’m living my life on the farm vicariously through you these days as had to retire due to poor health so really wanted to let you know I love what you do on your channel. Your video are pro quality, great commentary, filming and the content is always far ranging and interesting and the quality of your repairs is always practical. I could feel your frustration when doing the dam and although you may have paid more than you wanted for that little kitty Cat, she won’t let you down mate. Great job from Australia. Take care
Another excellent video. Interested to see how you tackle the track removal, I would have the dozer out side then release track tension and flick them off with the excavator bucket or chain and walk them off with dozer.
done that with old AC5, and an old JD 420C. But they are both spring loaded, just have to release tension, walked track off with a few long bars
On the one hand, OOF, that you are gonna have to do so much work on the tracks and cylinders, on the other hand, its makes great content lol.
This CAT is getting to be an old friend. We stop back to visit it every couple weeks and see how she's making out. Her situation is gonna be the focal point of that old saying. "If it's not one thing, it's another!"
Soooooo Satisfying watching this episode. I’ll sleep good knowing John did this to the D3
It always brings a smile to my face when I see a new video is out!
I know your taking about sealing the lid from diesel leaking out, but honestly id be more worried about rain water leaking in. Might want to rtv that instead of rubber gasket. Keep up the good work!
Woh up on pulling the tracks off. Try this instead: Fabricate a pair of new wear plates to bolt under the main track arms. Make them full width of the arm for ease of fitting. Then clamp them on with a generous amount of stiff plasticine with a thin film of Glad Wrap top & bottom so it doesn't stick to the wear plate and arm. Unbolt the plates. You now have a pattern to build up the upper surface of the wear plate with weld to compensate for the missing metal on the track arm. You'll need to use the old eye-o-meter to match the plasticine pattern, but it doesn't need to be perfect.
I look forward to your content and you have never disappointed. Thanks for all your hard work.
John, listening to your self-depracating and humorous take on things, make me think you're in my head. 🙂 It's very familiar territory, and at the same time, you inform and instruct in the best way possible; by trying things logically, and not being afraid to try...something that seems lacking in some of the generation...making a mistake, owning it, learning from it lauging at yourself and moving on. Please keep up the good work and content. I look forward to spending almost an hour listening to you doing things and letting me ride along in your head while you do it. 🙂
I'm staying tuned for sequel(s). Hooked on this stuff.
Thanks for encouraging me to struggle through difficulties by your example led. There is no accomplishment of anything without sacrifices.
33:49 soak the tip in mineral spirits for a minute and you can clean out the clog. If it's because the paint in the can is just not mixed well, Adam Savage showed a drill attachment for spin mixing paint cans, and someone on here used hose clamps on an old recip saw blade. Both options are much more effective than our puny arms 😂
Oh yes these next videos are going to be excellent!! The repair videos are my favourite, I hope John get a million subscribers 👍👍👍
John! You’re like the weird uncle we all need! Love the content! Your loss our gain!
You may find you want to use nutserts/rivnut to hold the cover on. The steel of the tank is pretty thin, and only a few threads will engage. This will make it really easy to strip out the threads. Nutserts will give you much more engagement and better hold.
its fine
@@bradenwuesthoff5639everything is “fine”, but the comments are so people can suggest better ways of doing something. Then everyone learns something new 💁♂️ it’s taking nothing away from this guys work on the day
Hopefully he never has to take it off again.
The problem with those nursery’s is they are not flush with the top of the sheet metal, meaning the gasket would have to be thicker to compensate for the non-flat mating surface
@@henryoppermann134 I believe you'd countersink the top plate hole slightly? (we are talking 2mm for an M12) Or just welding some nuts underneath would do. If the plate is really thin you can punch out a hollow for it to sit down into. That said, if you never open it up again then it'll be OK, but the idea is worth bearing in mind for other projects.
Appreciate the pick line is a 1/4" off the bottom but I would have raised that even more to minimize the risk of anything further being drawn into the fuel line. You done a fantastic job cleaning all that gunk out. At least now you have an access hatch for next time. 🙂
No need to, now it's clean
I thought that too.
You'd be surprised what another 1/4" would make. Providing that tank stays as clean as it is, I agree with your comment but I'd rather play on the side of caution and still raise it off a bit more but then that's me and a lot of OCD 😀 @@LinkinPark4Ever1996
Favourite part of the week, new Farmcraft videos.
I would have put twice that many bolts in the cover. I’ve seen leakers on tanks from too few bolts. Just sayin. 😊 If you are getting bounced around in the seat the fuel will be doing the same.
yeah, and why cot the middle out of the gasket? all that does is give another surface for leaks. Oh well, not our problem to fix eh 🙂
I know the trash from that tank has caused you lots of grief. It has a lot of crap inside it and fortunately you’re smart enough to accomplish a job of this magnitude. You will definitely be rewarded in being able to use the dozer in the future without those issues that have plagued you for a long time. Great job!
If you are only going to use the dozer infrequently, then consider placing those strong magnets inside the tank, place them close enough to the pick up tube to capture any errant rust particles, it'll save some of the issues. Or simply wait for your in-line filter to clog and then clean the tank :)
Hey Jon, thank you for what you do - all the way from Croatia. I’m 23 and always watch your videos after work (read: graveyard shift) to fall asleep relaxed. I find your videos very entertaining and I especially like the random emojis you put in them, it’s very funny (especially when you say something’s gonna be easy and you put a fast nope on the screen😂). You remind me of my dad when he was a bit more capable of doing jobs with me. Keep doing what you do and keep the style!
You do very good videos. I look forward to watching them every Friday. Thank you for taking the time to make them.
One big reason I built my truck transfer tank out of stainless steel. It’s 16 years old and looks brand new inside and out. Obviously different than an existing equipment tank but still… think about the future. It will save you time and headache. 😉
Also remember that the steel tank mostly redirects the magnetic flux along the layer of steel rather than through it to the other side. I know I didn't describe that super well.
John - When you finish using your paint rattle can, invert it. and clear the supply tube and spray nozzle by releasing some of the propellant until it no more paint is released. Keep the spray can inverted and store in that orientation until the next use. This should solve your spray paint problems for the future. Hope this suggestion helps. Use it for all the rattle cans you keep around.
I do like the temporary fixes like that valve where you find them still in place and working 10+ years later
Squatch has a nice homemade pin press. I realize that doesn’t do you any good, but I’m confident with your skills you could build one just as good! Good luck!
Great video John, I thought you were going to sandblast the inside of that tank to remove the rust,But you got it clean. Vevor stuff seems pretty good. I bought a 85 ft garden hose reel from them, Noticed the back was separating on the swivel mount, contacted customer service they were excellent to work with even though I'm in Canada , fixed it myself( like you would have) got payed back for materials used & money back for the product . Would buy from them again. Gord
Just keep buying old machines so you have "material" to do the videos ! Love the channel John.
To recharge your spray can, take a needle inflater for balls... and attach it to the spray can after you take the spray nozzle off. Turn on the compressor and press down on the needle attachment to allow air into the can. I use a milfaaukee 12v compressor set to 50 lbs. Shuts off when at said pressure. Works for wd40 cans.. should work for any can.... although the air may cure some of the paint... but hey... you want to finish the spray can... not store it for another year... or decade... or for your grand kids...
Yay new vid!!!!! Makes fridays even better!
Thank you John for such awesome videos.
When I lived in Brooklyn New York years ago fixing a gas tank meant removing it, putting it under the nearest fire hydrant, filling it with water, and soldering away. Gas pockets at the top made gentle explosions until all the fumes were gone. Ah, youth. Regarding your fuel tank patch, my concern would be rain water getting in: it looks like you've got it sufficiently sealed to prevent that.
John that’s a cast iron rail guide. Preheat rail to 400 degrees F and weld with silicon bronze.
I have used a porta power in a rectangular shaped steel cage to drive those track pins out. Oh, and lots of JB Blaster. I don't recall how I got the steel box over the track properly but I remember it was out in the woods in close proximity to a hornets nest.
IF you can't get the tracks off - I'm seeing a thick copper shim between the bracket and the bottom of the rail. Use a hard wire in the MIG and do build up to fill the missing area. Then find some strips of AR400 (or 500) and weld them onto the bottom of the rail as new wear strips. Oh, and always remember that there is "new cat yellow" and "old cat yellow". Not sure when the change happened.
I knew you would likely have to fix the tank, and I'm glad you got in and scrubbed it. Its maybe the most SATISFYING video you've made. Nice work.
Yeah and a long term PROPER fix...access port to the tank...wonder why they don't make one from the factory
A perfect example of why metal fuel tanks should be refilled daily. Condensation killed that tank. Nice job cleaning and fixing for future access.
Sorry Jon that you going to have to do more work on this machine, but I definitely interested to see the repair. Can't wait for next video.
Idler wheels. Fill the uneven area below with weld then put new wear strips over that.
Always enjoy your videos. I must admit, however, that I enjoy watching you fix stuff a tiny bit more than watching you use them when they are working.
51:50 It's very definitely a design flaw on the part of Caterpillar do not put an access panel into the fuel tank. Fantastic job as always.
Slowly i start to feel pity for you...but your pain in the required fixings is our benefit in watching a new interesting video!!
Seems like the bottom of those rails have 2 threaded holes @ 42:37. I'm wondering if you aren't missing some sacrificial piece that is supposed to prevent all that rail wear that you are seeing.
Hi John and great video. I really like your methodical, logical approach to repairs. I hope this isn't a stupid question. What kind of tool was that when you were punching the bolt holes through the nitrile gasket (for the tank access cover)?
You can often clean spray paint tips. Replacement tips are also good to have on hand. Invert and spray a little too clean, then wipe with a solvent. For supper 77 toulene works. Mineral spirits, paint thinner might work. You can also recharge the can with compressed air if you run out of propellant or get a chunk before the spray tip.
When I was doing Heavy Equipment Mechanics what we would do with those worn idler arms was grind them flat and smooth then weld a piece of sacrificial flat stock on top. When it wore to a certain point we would grind the welds and put another piece of material on top. This saves a bunch of time instead of welding up the surface and lasts almost as long.
john you are a brave man to take on that cat d3
Your work ethic is so immense..very impressive
Great job, John. I’m kind of glad to see we get additional video. Thanks
The cause of all you fuel dead acks is usually the fact the tank wasn’t filled at the end if each day as well as being unused or setting for a long time . Always keep tank filled to eliminate condensation
