- Working on a Cat D7E bulldozer with a Hyster D7H winch. Installing a new winch hydraulic pump, hoses, filter. Then using the winch to rip a car in half.

Andrew must have ran out of yellow paint. I always enjoy that part of the equipment repair process!
Id recomment putting some cable grease in the winchline, lubrication is very important and will make spooling way easier. Cable grease is also water proof and will penetrate into the cable fibers.
10 minutes of ripping a car apart and Andrew didn't even put it in the title of the video? The man knows how to reward his dedicated viewers! Thanks Andrew!
Don’t ever stop making videos like this in this format. So hard to find good videos like this on RUclips now.
hey andrew, i am a commercial boat owner and a tip i can give you with old hydraulic winchs or any equipment that have been sitting, you can just hook one side up leave the other side of the winch port open, start up the pump hit the proper arm for that direction and collect all the gunk on the other port with a bucket. Usually everything comes off in 2-3 seconds. shut it off and hook it properly. Good video thanks! cheers
Andrew, look in the bottom of the hydraulic reservoir and see if there are sand dunes of metal shavings/filings. These will forever clog your filters. Our injection molding machines came from the factory with piles of shavings in the 1100 gallon reservoir. It looked like a friggin' beach in there.
I have been watching these videos for years now, and I'm still floored by the tenacity Andrew has with projects. Knuckles busted, constantly panting and huffing to try to do something as simple as run a couple hoses. Researching filters and ancient pump systems. You're like a necromancer wrapped in a bald eagle dipped in diesel. God bless you, legend!
Andrew always finds ways to test his repairs.
This channel is truly one of a kind.
Andrew, my entire life is different from yours. I will never do the things you do. Thank you SO MUCH for teaching me about engineering, repair, tools, physics, rock, watercraft, excavators, and retrievers!
Andrew, your hard work is paying off. I admire your work ethic and determination to see things through. You are living life well and you have earned it.
Out of all the hoses I have ever fitted in my whole life. I have never found these hoses so interesting including the voice overs of grasping for air as you tension each fitting. Rechecking that filter makes you an outstanding technician
Andrew, although the Chainsaw Radio Installation will always be a sentimental favorite, this Hyster Stretch Limo Mod may well stand the test of time! Seriously, your videos always tell a great story end to end, and you include the right mix of education, entertainment, and personal courage to just get things done. I can’t count the number of times I’ve repeated to myself your excellent mantra that “cold weather is just an excuse not to work; just do it”. Looking forward to the next video!
I'm an aeronautical engineer , I have never owned a heavy machine or even sat in one ... and i still find Andrew content is so interesting .. i always get excited when i see a new vid is posted
Even at 65 years of age, i'm still fascinated how a small device that pumps a tiny amount of liquid can build enough strength to move such a massive weighted machine. There are literally thousands of pounds of weight involved here but yet that little pump will pull that entire machine on angles and often even up hill with other weight attached sometimes. This generation is also fortunate to have modern machines that are so powerful that they can be operated with a little joystick and a few push buttons and even having such luxuries as Air conditioning and heat and stereo in a enclosed cab. When i started out, everything was still cable operated and motor driven with gear drive units and some push button starters instead of pony motors to start the main motors. From Primitive to almost automated in just a span of 30 years it seems. Amazing.
That old dozer has had a very hard life, from the looks of all the battle scars it is sporting! Retiring to Andrews compound is just reward for it! That winch is impressive!
I am impressed you cleaned out the filter more than once! Nice job sir.
You can tell Andrew is still a kid at heart. Glad to see the old girl working like she should. Can’t wait to see it with a new paint job!
Really like seeing you getting these old machines working again and their attachments. I just bought a fully restored (every nut and bolt removed) 1966 cat D7 with hyster winch also. The history of it is, it was bought brand new here in australia by a western queensland farmer (where i live) to do one job and that was to clear trees and make a road on his farm and make firebreaks around the perimeter of his property. From what i gather he did that and used it mayne twice in the mid 70s and he got sick and it sat ojtside in the sun on his farm until the owner before me bought it in the early 1990s. He started to restore it when he retired in 2007 and slowly worked on it and other machines in his collection. I had wanted a bigger machine but i can't justify needing any bigger. I bought the machine for what i consider a good price and he knows it will be used. He retored it to a condition that he said isnt overly restored. The engine was torn down and rebult and looks new but nkt brand newparts werent pilished but parts that were meant to be painted were. My first job will be digging a new dam tomorrow as we are meant to get some welcome rain. Happy new year from australia
Agree w/John Simpich. The year of the dreadful shelter in place, my wife, my 4 y/o daughter and I binge watched this channel day and night. As this video demonstrates I was educated and we were all entertained. The videos brought my family aww and enjoyment at a needed time. As usual this video had a successful ending but totally cracked us up, especially my daughter.
