[@toeknee5464]

even if you overpaid you know you have a reliable machine you have gone through yourself now

[@woodcox0171]

That looks like a decent planer, the feed tables are interesting. I couldn’t see any snipe there.

[@DuaneMckenzie80]

@@woodcox0171 i was thinking the same thing, couldnt see any snipe.

[@FarmCraft101]

It had some snipe, but not too bad. Agree, it seems a decent planer for a crazy low price.

[@bombardier3qtrlbpsi]

​@@toeknee5464I second that 👍

[@matthiaswandel]

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.

[@These_Old_Engines]

A wild Mattias appears!

[@FarmCraft101]

Makes sense. Good to know, but at this point I hope not to need them anymore! 👍🏻

[@Tjousk]

Indeed

[@tutekohe1361]

“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.

[@FraLin]

It wouldn't matter how far the poles would be apart you would never get sufficient flux

[@andjuju6476]

I don`t get jealous very often but I think I am quite jealous of this guys cool demeanour & ability to fix & improve everything.

[@johnpeplow3985]

I never thought that I would find watching someone getting sludge out of a diesel tank interesting but I found it compelling.

[@Charlee_and_Pipo]

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.

[@Techathy]

When an FC101 video starts with a sigh you know it's going to be an interesting one!

[@gordonagent7037]

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

[@scapriglione8642]

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!

[@alcorbeil6226]

Hi John to remove the track, remove the grease fitting and back the idler wheel back then remove the tracks.

[@DMSparky]

Really excited to see the next video! You’re a brave man. Soon it seems like you’ll have a fully restored machine.

[@ltanthrax8435]

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

[@rjkStudios]

After the past challenges with the fuel system, it was so satisfying to see all that guck removed from the fuel tank. 😎👍

[@WatchWesWork]

I'd put those track frames in the "run until it explodes" category!

[@Ian-iu2tl]

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.😊

[@reakajohanson996]

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.

[@rpetty]

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.

[@FarmCraft101]

Just added to the description.

[@JesusThineBeTheGlory]

Oh yes these next videos are going to be excellent!! The repair videos are my favourite, I hope John get a million subscribers 👍👍👍

[@jamiefultz5937]

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

[@Krunsy]

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!

[@davey4731]

That metal cutting saw blows my mind. Goes through like butter

[@FrozenFingers]

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.

[@markusstaller1752]

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.

[@PaulieVavoom]

You do very good videos. I look forward to watching them every Friday. Thank you for taking the time to make them.

[@JCWren]

6:41 Jon, the flash on your phone is on.

[@mrsuperduty100]

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.

[@szki272]

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.

[@user-rq5eg1yz3n]

John, When you have completed repairs, you will have a new Cat dozer !!! The challenges that you have solved are amazing.

[@paulhammond7489]

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 :)

[@hubertwhitlock9968]

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

[@xyzero1682]

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.

[@haydenc2742]

Yeah and a long term PROPER fix...access port to the tank...wonder why they don't make one from the factory

[@joshuaolsen8844]

John! You’re like the weird uncle we all need! Love the content! Your loss our gain!

Make no mistake, Jon, I am SO GLAD you bought that dozer!

[@download77]

“shocking that that leaks” Made me smile.

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.

[@augustland8952]

Great content no stupid background music, nice work and really worth spending 1 hour watching, keep upload good job 👍👍👍

[@lawman5511]

Awesome video. American ingenuity on display. Caterpillar never thought anybody would want to clean out that tank.

[@rocksfire4390]

the content generation machine blesses us with more content, taking those tracks off seems like a massive undertaking. i'm sure the repairs could be done in like 1/4 the time but you reposition us and give us a good seats every time so thanks.

[@lycanthrope8979]

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. 🙂

[@sjv6598]

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 🙂

[@goltzhar]

It always brings a smile to my face when I see a new video is out!

[@randyballew8795]

You have definitely helped and improved the performance of that Cat

Soooooo Satisfying watching this episode. I’ll sleep good knowing John did this to the D3

[@odiesclips7621]

I'm staying tuned for sequel(s). Hooked on this stuff.

[@thomasrennison9461]

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!

[@pauldriscoll5010]

I do like the temporary fixes like that valve where you find them still in place and working 10+ years later

[@heel57]

Think positive - had the dozer been flawless we would not have had these interesting videos!

[@bmwbaker]

I look forward to your content and you have never disappointed. Thanks for all your hard work.

[@GTNLOST]

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.

[@andymann9861]

Great job, John. I’m kind of glad to see we get additional video. Thanks

[@anthonyhoult152]

Brilliant video John and looking forward to watching your next adventure. A tip on the spray paint cans, when you have finished spraying hold the can upside down and press the nozzle until no paint comes out. This stops the nozzle clogging up with dry paint 👍👍👍

[@mrkenenglish]

Favourite part of the week, new Farmcraft videos.

[@Kalle1995]

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 ❤😂

[@gutsngorrrr]

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.

[@madmodifier]

That used to work. Most of the time now (in my experience) they still spray upside-down.

[@FarmCraft101]

Agree. I always do that but I also let cans sit for years and then complain when they don’t work. 😂

[@incubatork]

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.

[@GRAZINGARIZONA]

​@@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.

[@gcranch9913]

65 Ford is just as great a channel as Farm Craft! He is one heck of an engineer

[@bob9483]

That dozer has certainly been good for YT content!

[@FarmCraft101]

My YT content generator!

[@Brauma54]

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.

[@stephenvale2624]

It is truly amazing how much labor is required to keep old iron working!

[@captaincrunch1949]

Excellent video! I have an old excavator and skid steer that require constant maintenance and repairs. Now I just learned from you how to fix my excavator plugged fuel line. The camera trick is a good idea!

[@tracywagoner4907]

The joys of buying used machinery. I am getting there on my backhoe currently but so glad I have learned what I know about the machine through fixing it.

[@trespass2085]

john you are a brave man to take on that cat d3

[@benclark5225]

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. 🙃

[@BPeterson730]

Would love to see you do a full fluid service change on your next video! I really enjoy your Cat D3B videos! You have taught me so much with mine. It’s a 1979 Cat D3B. Almost looks identical to yours.

[@UptownMovies]

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!"

[@MarkKelly1307]

Really glad I chose to watch this tonight. Ended up pulling the trigger on that planer. Been looking for a while now. Cheers, Mark

[@jerrodsimmons8356]

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!

[@reiteralbert3118]

Well Jhon I think many of us admire your tenacity to start and finish things ! keep up the good work! and thank you for sharing with us good and bad things! It happened to me a lot having so manny bariers but who else would fix them if not me! so we understand you very well!all the best!

[@silicon.alchemist]

Jon: Great video as always! I always take the spray nozzle off a paint can when I store it, and drop it in a glass bottle of acetone or lacquer thinner for storage. I have a whole bottle full of clean spray nozzles to choose from when I need the paint again...

[@terencecottington4273]

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. 🙂

[@LinkinPark4Ever1996]

No need to, now it's clean

[@DB-yj3qc]

I thought that too.

[@terencecottington4273]

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

[@jimnaz5267]

your repairs are very inventive, and fascinating to watch. One of if not the most interesting on KZbin. Thank you for sharing. I am not a mechanic nor do I have any heavy equipment, but I look forward to every one of your vids. Again, thanks

[@williamharbaugh3202]

Always fill your fuel tank at the end of the day and before storing it. Leaves no room for condensation and no more rust. Doing a great job and thank you for your videos.

[@martinvs6415]

Finally got time to watch this. No wonder you were going through all those filters, Jon. I think it was the best idea to open the tank and clean it up good. Although the tracks are a big job, I am convinced that if anyone could fix them right, it would be you. Thanks for taking us along on this adventure and looking forward to the next one.

[@paulpowell9579]

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.

[@joegrant662]

Hey John ! Where the track ends come together have teeth that mesh together. Find those and thats where the master pin is. Really enjoy your videos!

[@donaldbrown9437]

Glad you have a lot of equipment that enables you to do lots of repair work! Keep up the interesting video!

[@kennethelliott9092]

I really enjoy your videos. You actually get things done and explain why you're doing them. Everything is weighed against all the options of achieving the desired result and you are way braver than I am on tackling some of these problems. Have a safe and healthy day.

[@andrewdavy8166]

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.

[@walterlotz2085]

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

[@katbeck1867]

I've been waiting for that tank video! Didn't disappoint! I caught that pin being a pain at the very end...can't wait to watch.

[@TonyLambregts]

52:00 spoiler for your next video! Looking forward to it. Thank you for taking us along with your endeavors. Great video as usual BTW.

[@davebennett5069]

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.

[@jaywalt1311]

you cant do that on a lot of the newer cans, they are designed to paint in any orientation (or so they say lol), =(

[@ChiefNonsense]

Came here to say this but figured someone already had.

[@jefferywright4204]

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.

[@dannydunnagan3267]

You are like me always working on something, but it makes me feel good and glad I am able to do it.

[@wayneswonderarium]

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 😂

[@lennyf1957]

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.

[@ehcatsfaneric2211]

Your work ethic is so immense..very impressive

[@HazItMade]

At least it wasn't a tankless job! John, for many years my friends would refer to me as Tim, even though my name is Mark, as in Tool Time Tim from Home Improvement. They seemed to think I owned every tool known to man. And back then I had a lot more than I do now. But you have me beat, hands down, by miles and miles. They say that, "He who dies with the most tools is still dead", but if it were, indeed, a contest, you would be at the very least a contender! I have to say though, your ability in terms of "ounce of prevention/pound of cure" has both my admiration and respect. Wish so badly I was better at that! Anyway, glad you're on "track" to getting this thing 100%! Namaste

[@neffk]

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.

[@KerboOnYT]

Wow, it's no wonder that poor fuel system was cranky. Thanks for the video!

[@aresler6085]

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.

[@barrygrant2907]

What I like about your channel is your attitude. When I was training young airmen to be NCOs, I tried to impress upon them sometimes you have to make a decision and live with the consequences--right or wrong--because you own it. Doing something is better than doing nothing. Even when things don't go or aren't as you planned, your "It is what it is" is true, and you just deal with it. As for the tank, job well done. I would have painted or rust-treated the underside of the cover plate and also the fill neck since both those areas are more prone to air and condensation exposure. But yes, a full tank is a happy tank when it comes to rust prevention. One last comment, you could have placed one of the magnets on the inside of the tank next to the pickup tube opening to catch any metallic particles. Add me to your subscribers.

[@lucilleking7495]

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

[@Pwn3dbyth3n00b]

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.

[@thewayidoit8895]

😂 hey John, I know you were thinking to say this: about that thickness planer, the 6-1/2" yeah that's me on my best day!
