    hey matt, former forklift mechanic here, we had the exact same crimper machine in our workshop, dont waste time trying to calibrate it, when you change dyes for a different size it will all go to waste. the way you use it is how you did it the first time... crimp the first hose to the chart size and turn the knob until the light turns on, a couple tenths over is perfectly fine, but never go under the chart size or the metal sleeve will split and/or crush the hose. as long as you do this it will work 99% of the time with no leaks
    ...also, the lube is for the tip of the hose to slide the fitting easier, not for the dyes, we just used the same hydraulic oil to lube them

    Mango Bango and I thought reinstalling the main rotor transmission and GE T58 turboshaft jet engine on a Sikorski HH52a Seaguard amphibious helo was a b#@ch.
    What Matt took on is way more complicated.
    We had Polaroid picts to refer to making it fairly easy to hook up the various types of hoses and wiring harnesses.
    Plus every connector and assembly were match print labeled or stamped to the various assemblies.
    Kudos to Matt for doing such a excellent job restoring his Dozer and excavator.
    I'd fly in any aircraft he decided to restore because I've absolutely no doubt he'd go the extra mile to educate himself on what he'd be doing and his work would easily pass API inspections.

    Matt, in order to test the accumulator, run the hydraulic pump with no parts moving, with a gauge on the output. If you have pressure, that's a good sign. If you have normal system pressure when a control is moving but it drops to zero when nothing is moving, the accumulator is bad. Hydraulic pumps don't create pressure, they create flow. Pressure comes from the resistance to flow, either from work being performed, resistance to being pushed down the lines, or from the pneumatic charge in the accumulator. If the diaphragm is bad or the pneumatic charge has leaked down, the accumulator will be solid oil and provide no resistance, and thus no pressure. Loving the series so far!

    Hi, I really enjoy seeing you rebuild these projects entirely, piece by piece. Keep it up! I have done lots of hydraulic hoses at my current job with one of those handpump crimpers, and it keeps you fit 😅. Couple tips: If you have two 90° and they don't quite fit, you can put some vice grips on the ferrule and twist it, even after crimping. It's not perfect but works perfectly fine. Secondly, it is extremely hard to over-crimp the hoses in my experience. Doing it by hand, you can feel it getting exponentially harder quite a while before doing damage, and with an air pump, you will hear it slowing down massively. No need to worry too much about it! Thirdly, bigger hoses are harder to line up in the crimper, but generally easier to crimp since the metal is a lot easier to move than in the smaller ferrules. It will be interesting to see how long that crimper will last. The one we got at work doesn't look all that different and is over 10 years old and has probably done well over 10000 hoses, and only now you can see it getting tired.

    why excavators cost a fortune. HOW MANY people are needed in the factory to install everything on the big machine. The FIRST time I've ever seen an excavator completely DIS assembled and now....being put back together. Crazy stuff.

    In the Aluminum plant i worked at about 10 years we had a hydraulic shop with shelves with all the fittings. We had a table with a chop saw and on the bottom shelf of the table a hydraulic pump. There was a big old die crimping part bolted to the table which did the crimping. I've never seen a hand crank pump for this kind of thing. But you have your own portable crimper now. I'm an electrician but occasionally we wanted a hose that wouldn't be damaged as easily as flex conduit was so a 5000 psi hydraulic hose came in handy so we learned to crimp our own hoses. Nice video Matt.

  • @erickvond6825

    Could use a normal torque wrench with a crows foot wrench for the hose fittings, if you keep the crows foot at 90 degrees to the torque wrench handle you can still use the specified torque value for the fitting, any other angle needs an adjustment to allow for the altered leverage. You are doing a great job restoring this machine
