  • This is a set of Planetary Housing plates from a Caterpillar 785 Haul Truck transmission. The bushings in the reaction pin (guide rod) positions are loose and need to be replaced. In this video we show making the new bushings on the lathe including drilling, reaming and machining. We also show the cryo-freezing and shrink fit installation of the bushings into the plates using liquid nitrogen.
    In this video we are using:

    A tip for you that I have seen another machinist use - Put a thin rod in your tailstock, run it into the part to catch it as it falls off to avoid the possibility of getting injured by a chip or something.

    When you said “I will do that 17 more times after that” I could hear the resignation in your voice. However, as I’ve seen the way you work I’m sure that the 18th part will have exactly the same dimensions as the 1st. You have also demonstrated the benefit of having a good relationship with your suppliers. I hope some big companies take notice because often it is your supplier’s knowledge that makes your work easier. Again, great explanations about your methodology and more educational quality filming and editing from Karen.
    ps. I love the expression “love taps”. It reminds me of an engineering entry I saw in one of our aircrafts’ tech. log. An engineer had written “Percussion applied”. I think we all know what that means.

    Great video! Working with liquid nitrogen is something I'm very familiar with. I'm a retired Master Craftsman for a corporate jet manufacturer of 42 years. Part of my job involved was making and installing freeze plugs. Most of my job was pretty easy because Engineering would specify the diameter of the plug, but they only gave me a .0002" tolerance. Making plugs on a machine that only had .001" tolerance was a challenge to say the least, and I have made hundreds of them over the years. The small ones in the range of 3/16" was a real a** kicker. What was fun was taking the left over liquid nitrogen, usually about a cup full, I would pour on the concrete with a little toss and it would roll across the floor for a good 30 or 35 ft. Very strange looking the way it did that.

      clutch pilot bushings/bearings are generally removed the same way, pretty much any blind bush/bearing... slather some grease in there and giver a smack. sometimes the bearings are a bit troublesome due to the space for the grease to evacuate.

    • @chrisforgan731
      @chrisforgan731 2 ปีที่แล้ว

      i've seen it done to free a seized piston in a large stationary engine. the owner removed the head made a cover plate to suit tapped it for a grease nipple filled the bore with grease by hand before bolting the plate on and pushed it free with grease pressure from a normal grease gun most of them generate around 10,000 psi so that's a lot of force.

    I work on aircraft with tons of freeze-fit brass bushes in basically every larger fastener hole. A trick I have for dealing with small bushes is to use a normal vacuum insulated coffee mug as the nitrogen receptacle. They don't take much liquid to fill and are remarkably good at keeping your nitrogen in there for a very long time without it vaporizing. Plus they are much harder to lose small parts in among all the fog. Love the video!

    I once had to got to a Royal Engineers vehicle workshop in Woolwich, where I was fixing office equipment, to get some grease to pump out a bearing in a large Photocopier, and was surprised when the guys in the shop did not seem too know what I was doing. Used same technique for a Land Rover series 1 input shaft bush many moons ago. Think I peaked then....

What a relief when they all went in so smoothly (aside from the one in the offtake that you spared us!). Thanks for a very entertaining and enlightening video.

    I've done that! Only once on my own, though. A mate of mine (probably the best engineer I've ever worked with) showed me how to 'pop' bushes out of blind holes, by filling it with grease and then just tapping it with a drift. Some years later, I needed to get a worn phos/bronze bush out of a flywheel. The mates I had with me were all talking about butchery, until I had the opportunity to say; "Stand back, watch this." And 'bingo', out it popped. (They all said I was a smart arse!)
    Engineering is all about making that job look easy, but as Jack Nicklaus once said; "The more you practice, the luckier you get." You must practice a lot. Well done Kurtis and Karen.

I see this lathe work as a therapy that some people with the talent that this requires,,, are lucky enough to do, because it evades you from everything that surrounds you and all your attention is focused on each project that you create from a piece of metal
