  • In this video we are line boring and bore welding to repair a Quick Hitch (quick coupling) off a Komatsu PC300 Excavator. The pin positions on the quick hitch have a failed repair by someone else and the weld layer is delaminating and breaking apart so we need to weld them up and bore them out to spec. We also need to repair the spacer plates that have a cracked weld. This shows the step by step process to repair the pin positions using our Sir Meccanica WS2 portable line boring machine. There is also some air arc gouging and welding to repair the cracked welds on the spacer plates.
    In this video we are using:
    - Sir Meccanica WS2 Portable line boring machine
    - WIA weldmatic 500i welder

    I admire company's that let someone who's just getting started have a go at a repair for practice before hiring Kurtis and CEE to get the job done properly. Great camera and editing, Karen. Homie 2, Pigs 0.

    For those concerned with the graphic scenes at the beginning: piggy was clearly suffering a pox infection and was put out of his misery.

    Homeless looks very satisfied with a job well done, RIP piggy.

    Who else here has started having "No Dramas" instead of "No Problems" after watching Kurtis? LOL

    As a mechanical engineering student, watching your videos is teaching me a lot about how different components are made/repaired, and what considerations should be made. Great content!

    Just some lawyer print, if I may: Stunt pig toys used in this video. Stunt growls and grunting along with live staffy footage provided by resident Homey. (Good thing our little hero doesn't ingest all the stuff *points @ annilated toy mess on the floor*) All scenes of gassss shortage were simulated for demonstration purposes only - live gas was passed on the set while under supervision. Background clocks placed for comparison only - your timing will vary.

    It sounds like the customer has a good maintenance team. I'm just glad this was caught before real damage was done.

    Karen, having given us slo-mo tracking shots last time, you now add sound editing to your skills, I really like the way you took a normal speed sound and overlayed it on the time lapse and stop motion.

    Safety Officer has done a thorough job testing the strength of those Dog Toy Pigs & they failed miserably, well done Homey.

    One piggy went to the market, the other two were torn to pieces by Homeless.

    I love the fact that your customers can literally see everything you do showing how much effort you put into ensuring the repair is right first time !

    The sound of those pins sliding in was so satisfying

    You are so blessed to have a dog like Homeless! The work you do is second to none, but Homie is so precious. I wish I had a dog like him. 👍🏻

    I've said this before but you two complement each other perfectly. A fantastic machinist and a very talented videographer. Not forgetting the safety officer of course, who is always a good boi. Health to you all.
