Repair a CRACKED Caterpillar 789 Dump Truck Suspension Part | Machining & Welding

In this video we are machining and welding to repair a cracked Caterpillar 789 Dump Truck suspension part. This part is the top cap of the suspension Front Strut on the dump truck. There is a crack right through the weld joint holding the pin into the top cap and the pin has been damaged. To repair we need to machine out the damaged weld and pin before drilling, boring and weld prep machining the top cap to suit the new pin. We machine up a new pin using 150mm (6” inch) 4140 solid bar and then interference fit into the top cap before MIG welding with Hobart Fabco XL525 dual shield wire. The suspension part is then back in the lathe to finish machining the weld and pin down to size. We then drill and tap a 1" (inch) hole in the pin to complete.

6 thou in banana's 😂😂 great work mate 👍👍

[@CuttingEdgeEngineering]

Hey mate! Hahaaa yeah that gave few people a laugh 🤣🍌👍

[@bradgreen6923]

A big "Well Done" to Mrs Cutting Edge, the camera work and editing is always spot on!!!

[@AJKir123]

The last Guy that done it, what about the first Guy that done it was it not his doing that failed first?.

[@DuncanAitken]

4:46 Trippy! The framerate matches the lathe RPM.

[@Ricky-kt9dv]

Because there is a crack, wouldn’t the run out be a bit exaggerated seeing as the crack would have caused some miss alignment? Just curious if that is a factor you take into consideration or if it is negligible. Love the videos, cheers!

[@CuttingEdgeEngineering]

Hey mate good question yeah the crack will slightly exaggerate the run out. The pin itself hadn't cracked and was still in position but out of alignment

[@Ricky-kt9dv]

@@CuttingEdgeEngineering Cool. Thanks for the insight!

[@davecunningham7018]

Amazing!! Great repair if you can call it that. Better than when it left the factory! Great skills and love the workshop 👍🏻👍🏻

[@sandy1653]

Some silly bugger's been at it with the marker pen, bloody crack's big enough Ray Charles could see it.

[@CuttingEdgeEngineering]

😂😂😂 4 arrows just in case we couldn't see it

[@sandy1653]

​@@CuttingEdgeEngineeringThat's just silliness. It's as if they're worried you're going to fix the wrong crack or something. The missus is getting pretty good with those slo-mo shots as well. Thanks for another video, enjoy your weekend.

Seeing and hearing how robust and versatile the button inserts are, has really opened my eyes to better machining. I had thought one had to work only within the very specific strengths of each tool type. So cool, thanks Kurtis!

[@dalethedentist]

Your channel really is some of the best entertainment around, congratulations. Best bit , the pin drop in

[@markfryer9880]

That was pretty sexy, and oh so satisfying!

[@CuttingEdgeEngineering]

hey mate thanks for saying so we appreciate it! Yeah that was satisfying!

[@atlara]

As always, excellent and impressive. Greetings from Brazil! Alex.

[@CuttingEdgeEngineering]

Hey Alex thanks very much mate!

[@Matt-my7pz]

Weird how off center that "flange" was when the hole was finally bored out.

[@maxmintz511]

Beautiful. Great editing, too.

[@CuttingEdgeEngineering]

Thank you very much!

I'm here for the little head movement after a good plan has been set, don't mind me

[@FishFind3000]

20:35 you could almost use those large blued curls as Christmas decorations or ornaments on the tree...

[@CuttingEdgeEngineering]

Hahaa yeah at 30:46 my missus said that we were making Christmas tinsel 😂🎄

[@rainbowananas5040]

That whistle tells me it was damn near perfect :D

[@CuttingEdgeEngineering]

Hahaa you know it

[@Flyb4ck]

I believe you're talking about the whistle at 20:40, right? Why does it happen?

[@toysareforboys1]

@@Flyb4ck Pretty sure it's talking about 31:31 :)

It sounded that way didn't it lol

Good to see someone getting paid to fix up another’s stuff ups👍 also letting people know that fact.

[@CuttingEdgeEngineering]

Hey mate keeping it real 😎👍

[@Kowalski301]

Honestly, i'm not a fan of it's always "the last guys fault" I mean, have you ever heard a machinist or mechanic say "They actually did a pretty good job"? Remember, that the first guy who repair something, is repairing a FACTORY made part that failed in the first place, in other word, that repair could have been just as good or even better than factory, yet it often fail becuase the operator abuse the machine.

[@FlushtheSystem]

"Not a great deal of weld in there" Would you call that lack of root penetration? I would assume they should have repaired with a complete joint penetration weld?

[@CuttingEdgeEngineering]

Hey mate 100% lack of root penetration and weld itself.

[@leehotspur9679]

@@CuttingEdgeEngineering A bad penetrated root run, is a crack waiting to happen , fitter welder Ret Good luck for the future You have the gift Regards from Kiwi land

[@joespratt413]

How often do you check your lathe’ s chuck clamp for run out?

[@johnwalker4602]

Another amazing piece of work from both of you.

[@CuttingEdgeEngineering]

Cheers John! Appreciate it mate

[@motoflyte]

That's cool how the frame rate of the camera atches the holes when turning

[@Booyamakashi]

Yeah RPM was almost twice the FPS, so it almost perfectly aligned :) Some day we will see 24fps/48rpm or 25fps/50rpm.

[@ptroinks]

When was that?

[@phuongduy6134]

e thấy tay nghề a rất là cao

[@kevinkeating9090]

Why is there a hop in the plate when in the lathe? Was that from the last repair?

[@WendysAnime]

Kurtis be looking nice 😳, Great job as always!

[@CuttingEdgeEngineering]

Keeping the viewers happy 😎👍

[@michaelc.3812]

Karen, you really do an AMAZING job with the videography and editing. The outtakes are gold, and your artistic videography keeps me looking for new episodes every week. Thank you both!!

Thanks for watching mate

Great work sir, I have worked for a Cat dealer for over twenty years, we use the same tools lust have different names. Love your work.

Absolute legend. Love the channel and the out takes are total gold.

[@CuttingEdgeEngineering]

Hey cheers mate! Thanks for watching

[@notasbignow1]

As usual Kurtis I loved every minute I love the process of cutting the badly fitted pin and watching you turn down a new pin and welding it back in and turning the new pin down for the finished job absolutely amazing best regards from Scotland 🏴󠁧󠁢󠁳󠁣󠁴󠁿 🏴󠁧󠁢󠁳󠁣󠁴󠁿❤️
