Been gone for over 8 months and you come back with a 2 hour video? This is the best day in history
Well said sir cheers !!
Was his last entry really 8 months ago?
@@ronbuckner8179 Yep. Couldnt believe it myself
I was here yesterday after thinking I havent seen a video in months.... today BLAMO! Video delivered. Gotta love coincidences.
Sure was worth the wait. 2 hour video took me close to 5 hours to watch. Chores, dinner and shower got in the way.
The legend has returned
The commentary is spot on, for example 1:10:22
Needs another tour bus in his life.
@sethp0411 your not wrong 😂
💯
Legend has it....he does not know he's a LEGEND
13:30 “Got the handrail pulled off, shouldn’t be long now until i fall off and break my back”
KT’s matter-of-fact humor always hits home 😂
Got the riff of Shake hands with danger playing in my head immediately
@@bluikkso if you know you know 👍🛠
Mena mena mena mau
Even your cheap work is better than most people’s best. You’re a talented guy.
I agree 💯 %
I wish i could have just a fraction of the know how and luck he has
And his used parts shed. @@CharlesAAnnen-rh4mk

This is absolutely the best mix of talking about stuff, doing stuff, explaining stuff, and skipping stuff that exists in “social entertainment” today. Absolutely the best without question. Thank you.
Mixed with a pinch of dry humor.
Get the natty light boys!! KT3406E has uploaded!!
I need to go get some beers...
🫡🫡
Great, now I remembered I'm out of beer😂😂
1:11:05 “Why put the right oil pump on when you can put the wrong one on right here…”
this guy has a great sense of humor 😂
I spent 38 years working on diesels and tanks for the army and the Marine Corps so I know a little bit. Love your show.
Love your stock pile of parts. Retired now but when I worked on the floor and eventually managed the place, my younger techs would laugh at my stock pile of "junk" they called it I had upstairs and in the storage sheds.
Didn't take long for them to figure out just how good the "junk" was till they had to use it. Having some older trucks in the fleet or an old customer with a "classic" truck that needed something that was too expensive new, or even a parts shortage going on, that " junk" kept everyone working and the wheels rolling. I like the term "good used" as you say it. Excellent video by the way and one of the best engine break in procedures and engine brake test too.
I watched the entire 2 hrs and 10 minutes. If you were...say 75 years old and had worked as a CAT mechanic for 55 years, I could understand your level of expertise on just about everything CAT. I've seen all of your videos and each one leaves me wondering how the heck you learned so much in such a short time. OK...I'll call it a "gift" and be grateful that you continue to produce videos to show the rest of us how it's done. Many thanks.
hes the Cat whisperer
hes in his early 30's, gotta remember the internet and hands on experience he has.

video?
Many people start very young with hands-on work which is the best way to learn, and some just have a special gift for learning specific things! Also there's a lot of information on the interwebs to learn from today, you just gotta sort through it to find the good stuff! 👍🏻👌🏻🛠️🔧🔩🚜🦺🚧
✊🏻🇺🇸🦅🇺🇸✊🏻
@@asconstruction4146Yes he has. You got to look at his older vids.
This has turned into a good Sunday
Fr
Fr lol
Or Saturday
This is probably one of the best cat. Tear down and rebuild videos around! period!!! And i'm a sixty series guy and I watched the whole thing twice
I am not a mechanic but I am a long time trucker and the 3406E is far and away my favorite engine... and I've experienced MANY engines. Enough of that, this content is so incredibly, (and unbelievably), relaxing and enjoyable to watch. I totally understand how the content provider doesn't quite grasp why we keep coming back... but we do! For me, this is what TH-cam is all about.
Well said ❤
HES BACK WITH A 2 HOUR VIDEO!!!
2 things as natural as breathing happen when KT3406E posts a video...we watch it and hit the like button.
You forgot “crack a cold can”
We are watching the Michael Angelo of diesels paint the Cistene chapel of Caterpillars for all eternity! Breath taking!
I am an old shade tree mechanic, and always learn about 10 tricks from every one of his videos. simply the best. I hope every diesel training school in the USA is using his videos. I also appreciate his use of safety equipment. His analysis of wear and damage is spot-on.
“An extravagant amount of blow by.” Quote of the decade!
!!! 🤣🤣. Whatever blows your hair back
That was gold.
😂😂😂 he has a way with word's
Great to see you back. I'm a postman from Scotland and know nothing about CAT diesels, but I've watched every one of your videos. The Knowledge and skill you have combined with your laconic wit is brilliant to watch. Thank you for sharing these videos with us.
Is your name "Pat" or "Jimmy"
@@JohnSmith-wb6kq No. but I used to have a black and white cat.
Have a beer for me mate. Scottish people are cool.
@@philmckrakin6752 Haha! Love the name. Never thought of Scots as being cool before.
@colinmcmillan2642 you know a bit about Cats. You're even cooler 😎 😂
Here I sit dreading a 2 hour drive into the belly of the beast and boom I got a 2 hour video from 3406. Thanks for making my ride tolerant.
Your mechanical knowledge is only matched by your dry wit and humour. I fucking love it, I wouldn’t stay subscribed with this long between videos with out, thank you sir
“Took care of that dumb bastard” Best line of the whole video!😂
48:12-48:36 Touche’ 😂
Followed closely by " If that parking brake don't hold you're fixing to see a show!"
Ummm ok
The amount of knowledge you have about cat machines and engines for your age is impressive
Myself and three others designed the first DJB articulated truck which was eventually bought out by Caterpillar. The D400E was the last of the side cab "swing axle" front suspension trucks Going from a 3306T to a 3406TA was a big step for us, but one we never regretted. We also made a 55t truck with a 3408T, mmmm, not so good! I really enjoy these videos especially those featuring our articulated trucks.
I just watched this whole video without taking a break. This guy is better than anything on prime time TV or streaming and it’s not even close.
The Man. The myth. The Legend. Is back with a 2 HOUR video. I feel bad for my legs cuz I’m not getting off the shitter till it’s over
😮😅💩😅😂
✊🏻🇺🇸🦅🇺🇸✊🏻
You must be the same guy at the TA truckstop in Corning, CA about 35 years ago who fell asleep on the shitter and woke up screaming he couldn't feel his legs. Funniest damn thing I ever saw and heard. I damn near couldn't eat I laughed so hard.
Missed you and your dry humor. My Sunday is now complete.
Watched for the second time, can't get enough and can't stop laughing.
"You put the lube on the bolt. You smear it around. You take the bolt. Stick it in a hole and you spin it. Very exciting."
You kill me brother.
I am not a diesel mechanic, but used to operate heavy equipment for 12 years. I work on gas engines and repair my one cars. I’m amazed with the mechanical ability this guy has and explains everything as it goes along. Amazing videos thank you!
KT your mechanical competence and dry humor are top drawer… have missed your videos
I love how all of this video is just full of common sense no half ass repairs even for the overall content to be a half ass attempt in frame. Thanks for talking to the camera as much as you did it’s nice to learn from the experts who know what they’re doing. There’s those of us that will gladly sit and listen through it all. I learned a lot in this vid thanks for the ride along and the lessons.
Man I was hoping and praying you hadn't retired. Love your content. I'm coming off the road in about 5 years, and all I plan on doing is rebuilding CATS. 👌🏽✌🏽👍🏽
It's the EPA that's trying to put these guys out of business.
There's not gonna be roads
Vacuuming the battery tray looks so satisfying. That vacuum is a champ.
20:40 goes without saying, but THANK YOU for pulling liners with hand tools… absolute turbo genius coworker went to town with an impact on the shop liner puller and mangled all the threads last month
Nice to see a talented mechanic fixing something rather than throwing a truckload of money at it and simply assembling it. Great job.
An absolute treat seeing this legend back on here with a 2 hour special! 🙌🏻
Hell yeah 💪
This was the best $380 rebuild I've ever seen on any engine! And you are very correct in not throwing a lot of coin at this engine knowing the rest of the drivetrain is not in the best shape.
"Daily rents worth rebuild"
Going the 120 degrees on the rod bolts with the impact was my favorite part for sure
7:16, 1:27:55 For anyone wondering why those cam gears have rollers in them: these rollers function as what's known as a _centrifugal pendulum absorber._ These devices are a tuned system where the resonant frequency is always some constant multiple of the rotational speed (that constant multiple is known as the _order_ of the system).
For an inline-6 engine, the torsional excitation which the camshaft experiences is always six times its rotational speed, so an absorber on the camshaft would be tuned to the 6th order. Though, practical absorbers are always slightly overtuned (i.e. the actual tuned order is slightly higher than the exact order), due to limitations imposed by transmissibility and stability.
The path that the weights travel on also matters a lot. For smaller applications, a circular path is sufficient, but circular path absorbers suffer from a problem where the system's tuned order will decrease as the amplitude increases (specifically, the tuned order at 180° of swing is 15.2% lower than at 0° of swing), and if the weights move too much, the absorber can become unstable and actually _amplify_ vibrations instead of suppressing them. If this happens, you then need to decrease the engine speed to restore the system's stability, often to a speed which is a lot slower than that where the system destabilised in the first place.
Circular path absorbers are typically overtuned significantly (at least 20% or so) to prevent them from becoming undertuned (which is where they risk becoming unstable), while larger absorbers typically employ epicycloidal paths so that the tuned order is the same regardless of how much the weights swing. Also common on larger absorbers are bifilar (two-point) suspensions, which enable the use of larger and heavier weights than simple roller-type systems, which decreases the required amplitude of motion.
Newer engines are taking this a few steps further and putting pendulum absorbers directly in the powertrain. In an even-fire 4-stroke engine with N cylinders, the dominant excitations on the crankshaft are those of the N/2 and N orders. People in academia are even experimenting with multi-order systems where the system consists of two or more sets of absorbers of different orders which are attached or connected to each other (on a 4-stroke engine, one set of weights tuned to the N/2 order, while the other would be tuned to the N order).
In practice, I see putting these things on single-mass flywheels as a great alternative to dual-mass flywheels.
I love the sharing of knowledge in the comments of channels/video's like this :)
Thank you for that explanation. I suspected those might be for vibration damping, but it's wonderful to get an explanation from someone who knows.
that is completely false
@@UltraMagaFan2 What's false?
@@UltraMagaFan2Troll shut up
Perfect sunday morning treat
The man, the myth, the legend. KT3406E. He returns! And we appreciate it. Cheers ol boy
Thank you for taking the time to talk to the camera, always fascinating and educational!
I used to sell auto parts for a living. I used to have a few customers like this young man that when they came in, I just sat back and enjoyed myself. I always learned something new. They would help anybody in the store that were having trouble with their car.
Thank you for showing the rolling in of the main bearing. Heard about this, people just say "roll them in", but never seen the bolt / grease used nor how it was actually done. NEAT!!!
These videos could be a part of CAT training if you ask me, or at least required viewing.
@@johngreydanus2033 You know when it comes to CAT anything I'm a total ignoramus but I must agree!
@@kd5byb Ah, you're pretty well educated now, didn't think I would watch every minute but I did, a real gem at 53:00
I will never own or use a heavy Cat, but watch all your videos. Learn so much. Not sure where I will use it, but I learn a ton! 😂
The ECM is fuel cooled? Well you learn something new everyday!
I did a double take when I saw KT3406E 2 hour video in my feed! I am going to set aside some prime time to watch my favorite mechanic rebuild my very favorite engine! Now I must gather some cold beverages and snacks and put my phone on mute!
This man knows his sh-t and has the get er done spirit.
Just a real treat of a video! only half hour in but I could watch this all day.
I love this video. You always see videos of complete engine rebuilds new and machined everything. This video proves that you dont need a factory spec rebuild to make it work for another 10000 hours.
Sure have missed your videos. Thanks for not forgetting us and not being scared to throw us a nice long video like 95% of other creators appear to be terrified to do. Cheers brother.
Welcome back KT and thanks for making a great Sunday!
Just looked at the channel last night to make sure I didn’t miss a new video only to see that it’s been 8 months. Wake up this morning and instantly see a 2 hour movie of my favorite content to watch!!
I could honestly watch your videos all day, like today for instance. The simplicity and amount of information is incredible.
I’m no mechanic by any means but your videos fascinate me. Your attention to detail and your mechanical knowledge is brilliant. Well done.
At first I thought the issues with the engine was an oiling issue.
Which was seemingly "confirmed" by the incorrect oil pump pressure relief valve spring tension setting.
Only to find out that the real culprit was unfiltered air.
Seems like the airstream carried the majority of abrasive particles directly to Cylinder No 3.
But all in all, it was quite interesting and satisfying to watch the teardown and rebuild.
Thank you for sharing this video with us! 👍
Excellent observation and proof of why you need good air filters on any engine.
You should be teaching this to young men at a tech school witch we know so much.your a genius, waited 8 months, love your channel
This is an epic video. I've watched smaller stuff on other channels (Caterpillar D2 rebuild, etc.) but this mammoth effort (days or weeks of work condensed into 2 hours for our viewing pleasure) brings intimate awareness of Cat heavy haul powertrains to the average viewer. KT3406E you are truly a legend. All respect for your skills and knowledge and kudos for the excellent videography the entire time, I know how much effort it adds to any project. Thank you, sir.
I'll probably never do this kind of work on one of these, since they're not that plentiful here in Sweden.
But that don't make this video any less interesting.
Your knowledge of these engines is awesome. Insane, but still awesome.
Good to see you're back in action here on TH-cam 💪🏼.
Always educational, always something to learn.
Your good old R5, R6 Scania or Volvo is not that different. Get on it!
Glad to see him back. Always a clear concise explanation in easy to understand common language !
Glad you are back . My Grand pa had a bone yard in the woods on his farm , Lots of old chevys he got drunk and crashed and crashed running from the law . He would take a torch there and cut 2 or 3 chevy small blocks out of them and bring to his garage and I would help , He would Tear them all down and pick the best parts and build a engine for his old truck . He would get 100k mi out of it and then do it again and again each time it blew up . He drove that old truck till the day he died . You reminded me of him building that engin and making it work I sure miss him . Thank you .
Hell yes! That jake seems like it would stop a freight train. Sounds really sweet!
That is flippin great man!! You have the wisdom and experience of a 200 year old man. God bless!
Always love your videos! Have watched your videos for years. You’re a LEGEND for sure! Always impressive whatever builds are. I’m 70 years old and totally enjoy your skill set. Ronnie East, Tennessee
My dad and his friend used to own a sandpit back in the 80s. When I was a kid, I was put to work there loading trucks on a front end loader and running a track hoe in between. I had to replace the occasional busted hydraulic line and maintain the machines daily during operation. Never in the weeds mechanically like you do here. I haven't been around that work in many years. Your videos are quite informative and you obviously have a lot of knowledge at such a young age. I never knew there was this much to a piece of machinery aside from the limited work I did on the machines. I am really drawn to your ethics on repair and the willingness to do the job right. That is the most impressive part of your videos to me. You do an excellent job at keeping your shop neat and clean so you can work. I also like the fact that you keep those cores around to use on other repairs. This makes it affordable for the smaller operators to cover the cost of those repairs. I know it is time consuming recording and editing out videos. You would be surprised at how many people enjoy watching things like this. Nice to watch when you need a relaxed moment.
This stuff is what youtube was made for!
I have zero experience with any of this content but i absolutely love your videos.
Glad you're back. You should do videos more often, please.
What a fine surprise this sunday morn, glad to see all is well!
Noticed this last night at about midnight UK time & thought "Oh great I'll take the laptop to bed, headphones on & I'll enjoy that a lot", 15 minutes in & I noticed how long it lasted, so three AM by the time I got to the end, loved every minute, truck starts sweetly & sounds great, Thanks for sharing it :)
I like how you tackled all the problems and resolved them one at a time. Also like the humor. Looks like your truck is ready for this job. Thank you.
1:52 that's a mighty fine bit of blow by indeed.
I swear to god if I have to wait another 8 months for another video i'd be ok with that lol, top notch as always!!
Thank you, this was better than any movie I have ever watched !!!
I never sit still for a 2 hour video. Except these. As always, with the wait
Getting all of the remaining goodness out of old iron… well done.
Great vid! I used to build them machines for Cat in the UK, in fact its 50% chance thats a front frame i built, i used to watch the engines go in, in the assembly shop and always wanted to get involved. If ever they had to take the engines apart, i used to go into that shop and have a nosey. Retired now, and i miss the hands on dirty jobs.
Watched all the way through. Excellent interesting video. Thanks for that. Loved it.
What a beautiful symphony of a 3406 under load, a full set of jakes and flawless transmission shifts up and downhill. Thanks for demonstrating that you don't need to spend a bazillion bucks on a decent enough rebuild to keep good old equipment running. well. Nice work!
Great to have you back! I can tell you don’t care talking into a camera, but your videos are the best on TH-cam. They are Gold! Please keep them coming as I cannot go 8 months for the next one. It is amazing to have such an expert to watch and explain how and why. Thanks. Norm.
Even though it was a cheap rebuild you did this job throughly and meticulously. Outside as always 💪🏻
In Mississippi we have a machinist who can repair lower bores with the motor still in the frame. He has saved us multiple times over the years.
I was thinking some kind of line bore chamfer refresher cutter. You could make one pretty easy. Then just hook it up to your Milwaukee 1/2” and run it slow under its own weight two or three turns and you’d be good. I’d love to see it done.
I'd like to see that setup! Very cool.
I'm sure I've heard of this been done without removing the engine
@Flyanb That unfortunately would not even come close. There is a large amount of material that has to be removed to remove all the damage, and then an insert has to be put in to replace it.
@@KT3406E i would have just used the epoxy too. We have an iron filled epoxy that we use for foundry tooling that is tough as nails, tolerates high heat and expands similarly to the ductile iron cast block. I bet that’s the ticket! I suppose if it comes out and gets in the oiling system it’s so small it’s like bearing or other metal shavings you don’t want a lot but a little won’t wreck your day
This is impressive! I had no idea that it was even possible to do a rebuild without taking the engine out. Congratulations on a great project.
2+ hour video man.. I love every second of it. Your videos are just pure class! Keep doing it, we sure need it.
I sure wish you made videos more often, I learn alot and enjoy watching them
The cleaning of the battery box had me mesmerised. Such great sucking technique! Very insightful video. Thanks.
Hi, at first, I thought +2h was abused, but I watched it entirely - it is always a great pleasure to watch a man of the art working thoroughly. :)
That's my Sunday evening viewing sorted! The legend has returned!
Thanks for the post. Best two hours of entertainment for a hot afternoon. Hope to see more soon. Take care.
I'm no diesel mechanic but stayed for the entire ride. You have some real skillz! And great camera work & editing too!
The Jake diagnose and fix sequence is exquisite, thanks!
Probably the best video I have seen this year , fantastic
Agreed.
This made my Sunday 1000x better. Thank you!
I really appreciate the common sense approach to rebuilding an engine using what you can reuse and only replacing what is needed. Your comment is always very informative and no fluff. Looks like a good useable haul truck. Thanks for the videos.
I didn't think I would watch that whole video, but it was a good one.
Keep in mind this guy films everything himself, does ALL the work himself, and then goes in and edits the entire video himself. I think that's why this is one of my favorite channels on TH-cam
Yes, 3 full days spent just in the editing and uploading on this one. Thanks for watching.
@@KT3406E bless ya 😇🙏
Deadly video Sir, i watched it twice
I know I’ll never rebuild a heavy equipment engine but I like watching any type of engine repair or rebuild video. New subscriber here now.
I missed your unique sense of humor and your style of delivery! Great Sunday evening !Thank you.
Howdy KT! You post, I make time on the spot to watch 👌🏼
The CAT Master is back! Great Information as always!
I can see why you have 180k subscribers, that was an excellent video being both interesting and educational for me. You seem to get the balance just right with what to show and what to simply mention so it doesn’t become a boring “how to” video. Being extremely knowledgeable in your field not only helps you but helps the viewer understand what is right and wrong on the machine. I’m so glad you found that missing plug or you would be right back where you started in no time. Cheers, Stuart 🇦🇺
In my opinion this is a fine example of how you can achieve doing the wrong things the CORRECT way if done properly like this young man has done so .. One must respect how he has taken the time to explain and show in full detail how you can do these thing correctly on a budget and cutting corners BUUT the correct way..Absolutely perfect well executed and beautiful done !!!! 🤙
