The discs in that torque are supposed to be a bronze color, the color they are now shows that they are roached, they got real hot, my guess is that they ran it low on oil and burned up that torque converter. That torque is near bullet proof,

"If I was very smart I woudn't be doing this shit to begin with." Story of my life! This guy never disappoints.

The best part about this channel is the unexpected randomness of the video drops. This is like running down the stairs on Christmas morning, and finding double the presents you thought would be there.

Nothing better than a KT3406E video on a Friday night. 👍

Thanks for ya "deadpan" obsevations! Love the teardowns. Thanks for the look and your time.

Started to get worried KT. Thought you done left us.

Yeppers, nothing better than a cold beer and KT3406 video on Friday night. Wish he would do more. Business before fun. The way everything is explained is so detailed. Thanks for another great video. Take care and stay safe.

Putting groves in the old seal at 19.50 to stretch it and make it easier to remove is brilliant.

Magnificent. Your shop is so clean and organized it's scary. You could use it for a haunted house. "Where did Timmy get to?" "He was _...out of place."_

The machine work on all of those parts is just metal porn... so crazy how fine it all looks... and thats after a long service life. Thanks KT!

"You see that bolt right there, wont come off until you take that bolt out" Story of my life!

If you were in the big theaters I’d pay to watch your videos over ANY of the crap that’s been going on the last 15 years or so !

Don't throw shade on yourself saying your are not "smart". You've got knowledge and skills that I would bet most mechanics/technicians can't even compare to. Love watching your videos and the simple ways you explain these complex machines.

👍🏻👍🏻 AWESOME TEARDOWN WITH EXPLANATION !!!!! 👌🏻👌🏻 The discoloration is very excellent and THERE WAS SMOKING HEAT IN THERE !!!! It would be interesting to see a graph on the trans oil temp, and time of day?????.... The crank alone in that engine is GOLD and well worth your invested time in the wrenching.....You got a HELL OF A MESS there in cleanup, 🤔🤔BUT we just got that intriguing wonder of what " KILLED THE CAT " 😏😏 THANKS FOR THE AWESOME VIDEO, ALWAYS INTERESTING TO "SIT BACK AND NOT SKIN MY KNUCKLES" GOD BLESS, BE SAFE!!!😍😍😍😍😍

Seeing a new KT video on a Friday night? Can't beat it.

"If I was very smart, I wouldn't be doing this shit to begin with." LOL! You are hilarious. And another interesting video, thank you.

Thank you for taking the time to put your videos together and sharing with us to enjoy. You have knowledge and talent I wish I had.

The part I enjoy most about your videos is listening to someone who knows what they are talking about, and shared it with us as well. Thank you.

Always enjoy learning new information about motors!!! Keep up the great videos, KT3406E!!! I’m a truck driver, by trade, but, I always enjoy learning the inner workings of a motor and what each part does!!! I know a VERY LITTLE BIT about working on them, but always make sure I keep the oil, coolant, and fuel at the proper levels!!! I’m always wanting to learn more about them, and how to keep from making mistakes that could seriously derate the performance!!!

I wonder where this guy got his training? I heard him refer to himself once as a “hillbilly", however this isn’t remotely true. This is a Master level mechanic with experience decades beyond his young years. Respect!

Best thing about your videos in my opinion: you explain how to do it, and you don't show the redundancy of filling your video with the removal/installation of every single bolt/component you remove or install. Fantastic and informative content sir without all the boring stuff!

I'm learning a lot watching these. Thanks for showing these POS from all angles, got good idea where stuff goes.

Those Speedy Sleeves can be tricky sometimes, but you got the right removal method down.

The legend is back!

Always have to stop when I see a new video. You never let us down with the information of CAT.

You’re pretty Damn smart in my book! I think you have a gift that few will ever know! Love you videos. Ronnie East, Tennessee

Be proud, your an expert in heavy machinery.

Very informative. Thank you for bringing us along!

I'm very impressed the knowledge you have stuffed in your brain Videos are very interesting, thank you

You know it's gonna be a good weekend when KT3406E uploads!

Amazing to see the crazy engineering it took to build these monsters.

The way you removed that lip seal was gangster

We miss your videos !!!

Love this kind of raw unfiltered content.

I love how quiet the Milwaukee impacts are.

Another great video! I always have a great admirmation for your work ethic and knowledge. I have absolutely no clue about heavy equipment operation but if I saw that discoloration in a light duty truck I'd lean towards low fluid level at some point in the past. Of course by the time they get to me they've already changed filter and fluid and everything's always fresh and full. Probably for the first time in that vehicles life.

The torque converter hardware that you were referring to that you were unfamiliar with is the one way clutch for the stator. The stator is only allowed to spin in one direction to assist with multiplication of torque. It takes fluid from the tc turbine and redirects to the tc pump when there is a big delta in pump vs turbine speed (accelerating from a stop)

When you see the huge number of parts that have to fit and work together, you realize someone had to design all those parts to fit and work together. Amazing how it all does work as well... Thumbs Up!

Constant tension, and spraying with silicone oil, or silicone based penetrating oil helps with removal of O-ring sealed connection.

Miss you kt

Man you crack me up , " If I was smart I wouldn't be doing this " I said the same thing about working in the oilpatch.👍

I could think of a large quanity of service techs that should watch these videos. I feel like I need to go buy a 359 Pete and ship a C15 to KT and get back a turned up C18. Seriously I enjoy the videos... Thanks for all the efforts.

Just made my night with this

Never get sick of hearing you call something a greasy piece of shit, makes my day 😂

I was trying to find your career video how you changed careers and couldn't find it. I admire you for having the guts to totally change gears and do something else no pun intended

I never had much interest in this big machinery ! That has all changed now . This is one of my favorite channels now . Great commentary and expertise! I now know more about this big iron than I ever thought would ! Thanks 🌵

Thank you so much for the upload. I always really like your tear downs.

Check the internal clutch splines the friction disks engage with. We had a case/IH years ago tie up between 2-3 gears. We wanted to make sure any problems were evident on teardown so we ran it in the field pulling a large disc while binding between gears until the exhaust pyrometer pegged, let it cool down, and repeated until we knew for sure this warranty job was worth the trip. You couldn't stand beside the tractor. On teardown the clutches still looked brand new with heat signs in the case around them. The only failed part was the splined shaft the clutches engaged on. They had miniscule knicks due to a soft metal shaft allowing the clutches to dent them around .001" for every tooth and barely visible. But the knicks were in a way they held the fiber clutches together engaged with the steels causing drag. You may not have had a slip so much as a non-release causing heat build up.

Impressive product knowledge and breakdown analysis. The filming ain't bad either. Thanks.

I never understood diesel engines, nor wanted to work on them. My brother on the other hand went to trade school for them while I went the USAF Jet Engine Mech route. Now I enjoy watching diesel mechanic videos. Thanks @KT3406E for doing this and making it educational as well as enjoyable.

Your knowledge on everything is mind-blowing. Keep up the killer work.

Great video! Thanks for taking the time to put this video together! Thats just the right Torque Converter I need for my Dodge. Keep up the awesome work!👍

Thanks KT. Always worth the wait.

you know its a good day when KT uploads

KT, morning... I thoroughly enjoy your videos... I think it's because I know so little about diesels... You express yourself well... Easy to understand and learn from... Thanks for the relaxing times... Dave

yay another upload. love watching your stuff

Thanks for the show a lot of work chasing down a failure but a learning event just the same

Thanks for continuing my education. You explain things so well I don't sound ignorant talking to my smart son.

You are really good at a first time teardown. knowing what to look for that lead to the component failure. that is definitely the sign of a top notch technician.

Man I learn so much from people like KT3406E.

🎉👍Nice to see @KT3406E back on the YTube big screen! Thanks again for all you do my man.👌👍🚜⚡💥💨🛠️🔩🔧⛓️📏⚠️🚧🚚😀🍻

The thing that you didn't know what it was at 39:45 or so with the long rollers is a one way clutch. It lets the unit spin one way and locks against rotation in the opposite direction. Same as car and truck transmissions.

This guy is awesome! So talented, a pleasure to watch!

Thank you KT3406E, great video 😊Normally the American guys talk half the videos then do a bit of work, you use a minimal amount of words explaining as you go along KT3406E (JAKE?) ITS BRILLIANT Mate 👏👏👏👏👍🍺😊

Thank You for the time and efforts to share the information. Best Wishes.

hey kt great to see ya back you do get stuff keep at it!

Might’ve never locked up thus generating a tremendous amount of heat in the fluid. Your videos are excellent thanks for taking the time to share!

I liked that trick using the chisel to stretch the inner sleeve on the rear main seal, I'll have to remember it next time I come across similar problem.

I appreciate your ability to clearly explain things. I don't have any background in diesel engines, but I'm learning!

this is the best part of youtube right here! never know when the videos are gonna drop! and it's always a good thing to see! keep the vids coming!

The stator one way clutch doesn't just freewheel when the converter is locked up. When there is a big speed difference between the input and output, the stator is back driven and multiplies the torque. As the slip decreases, the stator is no longer back driven and will start spinning. That lets the torque converter transition into being just a fluid coupling with less slip. The clutch on the stator existed back in the days before locking torque converters were in use.

Now that's a breakdown, love this channel.

Always appreciate your videos.

In the 90,s I worked at Avon gear and we cut those teeth in the torque convertor housings. I believe that part # is 8551? Since your videos I have seen a lot of gears I cut in all different applications. Keep up the good work on these videos, I really enjoy them.

Glad to see another upload man, I hope to see you do the build that cranks going in.

That looked like a 1-way clutch on the stator. When you find out KT, you should make a video or something on your findings. Nevermind I wrote the comment before you finished the video.

Another great tear down video 👍

I would guess a failing lockup solenoid or caused a drop in main pressure to the lockup piston in the torque converter and it got hot because of that. The valve issues and everything else that got effected was from them not paying much attention to converter temps or just not caring. I don’t know anything about these transmissions but I work on a ton of twin disc transmissions that are the same setup and same issues. Been wrong before though.

Good job explaining why a piece of equipment cost a million bucks without saying this is why they cost a million plus

Diesel Jesus! I hadn't noticed you uploaded until 5 months later. Gotta get notifications for this!

Thank you for still posting videos sir.

I will give you credit dude you are smart when it comes to heavy equipment and and cat engineering and motors

KT college is in session. Learn so much from you. Keep ‘em coming and never think you’re not very smart.

Great work big guy very informative to a layman like myself but always like watching to see how things work on complicated equipment and to see how to properly disassemble a piece of equipment the way it’s supposed to be done no cat dealer or shop is going to illustrate how each pump,filter,sending unit gear works and how to replace or repair Thanks again and will wait patiently for the next posting

Thanks for the video KT

Nice, guy. I enjoy your videos.

this one is the best one yet keep them coming

another great video.. Not many of these out there with explanations and dry humor.. Thx!

Your a good man 💯 working on CATS.. time and patience

It's really a lot of work, apparently you know how to put it together, I would think so because you're a professional! !

One way trip for this truck... parting it out? Very interesting what goes into the drivetrain. Thanks for showing that in detail...

wow! another amazing video from the master himself!!!

I enjoy your explanations. You're smarter than me

Something to be said about peeling off that perfectly aged, crispy crunchy gasket! Love it! ❤️

Great video as always! Thank you!

You are very good at what you do love watching your videos lots of parts on those engines great work bud .

Great video and nice details. Cheers for sharing! As an heavy vehicle passionate, you make me wanting to get such a CAT piston as a display item XD

This guy is awesome. Love your content.

"If I was smart I wouldn't be doing this shit" I don't know man, as an engineering student, I see machinists, craftsman and tradesman equally. I don't mess with those people, they know their shit. Y'all are smart too.

You're the man KT!
