Line boring and REPAIR Cylinder on CAT 12M Grader | Sir Meccanica WS2

Published 2021-09-03
This video is a job we did to repair the damaged articulation cylinder and replace the bushings on a Caterpillar 12M Motor Grader. The bushings are worn out in the chassis and one of the articulation steering cylinders is damaged. This shows the step by step process to repair bushing position on the chassis by welding and line boring using our Sir Meccanica WS2 portable line boring machine. There was limited space and it was a challenge! We also show the steps to repair the cylinder clevis that is bent and worn out from the steering pin and then complete the job with some paint before putting it all back together.

In this video we are using:
- Sir Meccanica WS2 Portable line boring machine
- BOC Smootharc Advance ii 250C
- HMP-150T Hydraulic press

  • Trying to convince my wife that I need a line borer to put the holes in her donuts, it's not going well..................great job Team CEE, keep up the good work.
  • This man is too young to have so much knowledge and equipment. Guys like him make me feel like I’ve waisted my life.
  • @davemaccarter64
    Wow, returning repaired parts to factory new standard dimensions so the customer can do field maintenance with standard size parts ! What a concept. The owners of that machine certainly did pick the right shop for that work to be done. A fine piece of workmanship you have done there Curtis and an enjoyable watch. Give Homeless a pet or two for me.
  • @maxnex7676
    I liked the "fuel cell" installed by the customer 1:38, I could have sworn it was a 5 gallon plastic jug. Great repair job, and another fine video by Karen. Thank you.
  • @adambrown2626
    I can’t articulate how much I enjoyed this one, you guys are definitely a grade above the rest. Love the longer vids.
  • @boNOOBod
    All that weld by hand. Without any holes after boring. Very impressed.
  • @peterdubya1788
    I can't wipe the smile off my face. You 3 are the best. Here, you gave me snap gauge line bore check, I give you Bridgeport front of the table T Slot mounted pillow block bearing, then line bore, swing that head over, the imagination is key. Take care, love it.
  • You sure tell how much you enjoy your work. You and Caron and Homeless do a great job as a team. I am in no way a machinist or mechanic, but I certainly enjoy watching your videos and have Evan learned a few things in the process. Keep up the great work!!!!!!
  • @justaddwata
    Have to tip my hat to Karen - great camera work there. Some real tight and difficult shooting locations - and I am sure Kurtis is not always the easiest guy to be filming around! Great job guys!!
  • I'm rebuilding the driveshafts in my K5 Blazer. You know I'm going to be using that rolled up piece of paper in the u-joint holes when it comes time to re-paint it.... Thanks, Kurtis! Such a simple solution when I've always gone back with brakekleen on a rag to clean overspray.

    One guy, some solid equipment, one giggler, one good dog, and a bunch of chewed up machinery. Fuck it, let's make a YouTube channel. Subscribed.
  • @scruffy6151
    That explains why you have the whole machine instead of parts. Well done.
  • @bretf5371
    You've got to admit, with the power of video editing you hide all your impatience and look like a saint...that is until you get to the out takes and see just how frustrating your craft really is. I so look forward to the f-bombs at the end of the videos!!
  • @reddpanda7343
    I was glad to see that Homey did the safety check before any work was started.
  • @zachiotis
    Love seeing young blokes working with passion, congratulations to both of you guys specially to the young lady for taking care of not only video recording but editing and uploading as well. And am saying that as no one can understand how difficult, time-consuming, and what level of expertise needed for the final result.Great effort!!! Am a huge fan!
  • The welding on the machine is called "Acrobatic welding" Nice to perform as a Circus act also. Camarawork as always "perfect"
  • @Daniel_cheems
    This man is a wizard and his lovely wife knows how to get those great camera shots for us. Awesome repair!
  • First off.. HUGE PROPS to the customer that actually prepped that machine for you!! 👏👏👏 Not having to deal with a dirty mess and pulling a ton of parts off just to get to the already pain in the ass location of the problem is so appreciated!!! THAT is how you get on the best side of a shop owner!! Awesome work as always you two and pup!!
