Bolt Hole THREAD REPAIR Bulldozer Transmission Cover | Keysert Key Locking Inserts

The bolts holes are stripped and damaged on this Caterpillar D9T Bulldozer transmission cover! Someone has also tried to repair one of the holes using a self tapping thread repair insert but the hole is in the wrong spot. This video shows the step by step process to repair the damaged bolt holes including drilling and tapping using the milling machine before installing new thread inserts. The inserts we are installing are Keysert key locking heavy duty thread inserts and are one of the best methods for thread repairs!

I love this channel and especially seeing another beautiful Caterpillar casting! I was a wood pattern maker apprentice at the Cat Mapleton IL foundry back in the 80's. We made the wood patterns and mock-ups that started the prototyping process for each casting part number. The wood side had 50 journeymen and 2 apprentices; it was the best, most exciting job I ever had. The pattern shop was connected to but separated from the foundry. It was well equipped, well lit, air conditioned, and quiet. Some of the journeymen served their apprenticeships right there at Cat. Others came from all over the globe and from all aspects of industry. One journeyman learned the trade during WWII while serving on a submarine tender ship in the north Atlantic! All were immensely talented. I was moved around the shop every 6 months so I could work and learn from all of the journeymen. Patterns and core boxes were made 'old school' by hand from mountains of mahogany. I remember working on the first wood patterns for the then new 3600 series engines. The V12 variant was so big it took 5 days for the casting to solidify! By the mid-80's cnc machining was coming on fast and the Cat pattern shop (and most corporation shops) was no longer viable. Being a lowly apprentice, I was first to be laid off. I finished my apprenticeship at another pattern shop specializing in aviation super castings and worked as a journeyman on castings for F-14, F-18 aircraft, and various other defense components. I heard the Cat pattern shop closed in the early 90's. I think back at my time at Cat with great pride. Fond memories of mahogany patterns being shaped up by hand to make the first prototype castings… many looked just like this one!

I listen to your videos while I’m working occasionally just for the shop sounds. Back in my early days we did the drilled bolt trick but we drilled and pinned the edge kinda like your inserts. I appreciate your videos. It’s nice to see a different side of things.

[@macstmanj3]

Hi Kurtis, great work!! I've done a lot of engineering work with castings and especially threads and repairs. One thing I've done pretty often is filling out of place holes with bolts/threaded studs, machining them flat, then drill a 2-4mm hole on the transition between the casting and the bolt. Drive an oversized pin in there, and no way on earth will that thread repair move ever again. Your repairs are always top notch, I just had to be an engineer and give my opinion which no one asked for.

[@MathijsHeideveld86]

what keeps surprising me is the endless patience you must have to keep delivering consistent good work. the tolerances are so small, on pieces so big, yet (what we see on camera anyway) is consistent good work! hats off to you. also, happy birthday to Homey!

[@1arm_658]

Great job. Just a bit of advice from a Loctite engineer. Blind holes need to have some Loctite placed into the hole as well as some on the thread. The airlock created in the hole will push most of the Loctite out of the hole as you thread the screw in. Look at the video closely to see how much Loctite ended up being wiped off.

[@TheBibliofilus]

Also Loctite is truely terrible for ones health and is just about the only chemical I keep of my skin at all costs!

What a fantastic way to repair a bolt hole, never seen that before.😲

[@user-yc7nv2qx2n]

In fact, this method is very common. It is often used in repair workshops. In actual production, it is also used, such as machining a bolt hole on POM that bears a lot of force.

[@marklowe330]

​@user-yc7nv2qx2n you are correct it's how it's done.

[@SeanBZA]

Also used as shown here to walk a bolt hole if it is off, fixing a mistake a lot easier than making a new part. Very common on moulds, where you often just have to tweak a few of the mounting points for different machines that do not all fit a common pattern. Also done with bolts that need to handle a lot of load, so the parent metal interface is much larger, to spread the loading out to something it will survive.

Never see an 11 y.o. dog who’s so lively. Wow.

[@hamongog]

I've watched most of these. At least a couple of years? This is one of the best. Curtis is a serious MF. His partner seems to have things figured out. That dog cracks me up. I'm about as far as one can get from machining. I look forward to Fridays because of this shit. Thank you!

Excellent video on a different type of repair from the master. I thoroughly enjoyed it.

[@CuttingEdgeEngineering]

Glad you enjoyed it

Once again the title fooled me. I was expecting a transmission part laid up on the counter and repaired with a thread repair system. WRONG! I forgot that CEE repairs come in the door on a pallet carried by a forklift. I guess I should have paid more attention to the word bulldozer. An excellent thread repair video--just done in XXXL size!

Видео очень понравилось! Сама работа честная и вы помогаете сэкономить клиентам деньги. Это очень хорошо! Хоми с днем рождения🐶!

Nice work. I've not seen these inserts before, they look good! I was wondering why you hadn't faced the bolt down then of course it was with the facing of the mounting surface later. I especially like the extra work on those extra hole faces. Noticing & taking the time to repair them is the extra service people really appreciate! Good Stuff!!

Nice job there Kurtis, seeing those CAT inserts takes me back 45 years when I worked in a machine shop in the plant workshops on a road building project in SE Iran, most of the kit was Caterpillar, D9H, D8K, 966, 980 etc. plus generators. Wish Homey a happy birthday from a damp and dismal Somerset, England.

Real engineering 101 stuff. This is often more interesting than many other things as we see how you overcome issues.

[@diepzeekomkommer]

These videos have become a week ending ritual for me if that makes sense. I look forward to them every week, keep up the marvelous work 👌 Thank you for the awesome content😊

[@Thepriest39]

Excellent work. You are able to think outside of the box for repairs like this. You defiantly take pride in the work that you do. That is becoming rare these days.

[@bobqzzi]

That was a tricky repair; a lot could have gone wrong. Well done

[@user-tz2nt5mn1n]

Kurtis is indeed a reliable mechanic, with a manual machine he can make very precise items. The video display is also very good, I have watched all of your videos, very impressive.

[@petermcconaghie7745]

No doubt about it - you do very fine work folks, these are so bloody good to watch!

[@michaelmclachlan1650]

Hear hear, that refacing of the bottom bolt mounting faces shows the work ethic we respect.

[@brenwyattm0rij909]

Wow, what can I say, what a video ! I usually predict what’s going to happen, eg. fill with weld, start again etc. But not this time and as for the home made Shear Bolt… Bloody Brilliant Mate. Great team, keep um coming please.

[@Watchyn_Yarwood]

100%

[@freethought2296]

Going the extra mile, it means everything.

[@javig5045]

Oh yea Happy Birthday to Homeless, Homeless indeed, what a contradiction in terms, what a happy boy he is, just a bundle of love and joy, love to see that...Javi G.

[@SubramaniamLakshminarayanan]

This video should be used by engineering schools and colleges as a text-book example of thread repair, giving all due monetary and emotional credit to Kurtis. Awesome!!

[@cat02791]

Because of you I have metal lathe machine. I am a welder. Thanks for your great videos that inspire me. Khartoum, Sudan.

[@CuttingEdgeEngineering]

hey mate that's awesome!

[@cat02791]

@@CuttingEdgeEngineering really thank you very much.

[@franktyphoon98]

Those thread-repairing inserts are some of the coolest thing I have seen in a lot of time! Loved watching them being applied

[@Redneckweapons12]

I absolutely love watching you work the pride you take in your work is amazing. I also think your dog is so well behaved he listens so well to you and he’s so handsome.

[@mk84ldb]

Removes that insert like a Boss!! If I ever need anything repaired, I am sending it to you and I live in the US!!
