Caterpillar 3406E Diesel Engine and Torque Converter Tear Down - 40 Ton Haul Truck

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.

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

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.

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!

"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.

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.

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.

Please upload another video 8 months is way too long!!! You tube is boring without your videos

I worked at Cat Morton back in 2000, in purchasing, ordering friction materials. I got to tour the Raybestos plant where they made discs like that. They stamped the steel core from a coil, flattened the discs, broached the splines, heat treated, nitrided, etc. For the friction material, they made their own paper, impregnated with resin, bonded to the core, and then cut the grooves with a gang saw with 5 or more blades. It was really cool to see the process. Also, the finished friction material was a light brown, definitely not black.

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

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

hey man. if you ever do a runaway diesel again you should add 50% petrol to the diesel and it might run hotter and explode.

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

Dude you curate one of the best YouTube channels, hands down.

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!!!😍😍😍😍😍

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