Nice show of the operator view! Great ol Cat, I used to have one of those D9G with pony Moyer and hydraulics up front. Definitely fun to run…. And kept you busy with he split dozer controls. I miss the sound and simplicity of those old machines, they all have they’re own personality. Glad to see that machine still working at 55 plus years old, they were built to work hard and last a lifetime, without all the electronics; they keep on working. No machine built today will ever stand the test of time like these, the electronics systems and sensors will fail long before this machine will die! Thanks for showing!
They are tough! I had to finish putting this one back together after a fire that burned up most of the electrical system, and a bunch of the hydraulic and transmission hoses. It took most of a day to completely redo the electrical system, but that was replacing nearly every wire and cable on the machine, making new harnesses, shrink wrap, mounting clamps, etc, compared to weeks to just install new harnesses on the new ones! Lol It doesn't currently have lights, so I didn't have to run those harnesses, which saved me a lot of time. This one had the pony motor replaced with a starter 10 or 15 years ago, which is nice from my perspective! ;)
It still is at this job! Lol I started out on a D9H 35 years ago, and this one runs just about as good as it did back then. And I receive your blessing, and send back blessing and protection and healing for you and your family, in Jesus's name!
As an experienced off roader, you would have gotten stuck! Lol These wood shavings are a very interesting surface to drive on, and easy to get stuck if you aren't paying attention, even with a dozer or large loader. And you would probably roll over backwards if you tried climbing the slope I went down at the beginning, notice I had to engage 6wd and stand on the roll cage to keep from going over the hood lol But, it would be fun to try to hit this pile in a rock buggy, at least it would be a cushioned roll down the side!
@@ke6gwf I couldn't handle a piece of machinery like this, I was poking fun at our conversation from my channel. I could do the hydraulic work on that unit, but I wouldnt have a clue on how to drive it. I built my own house, but my best friend is a professional contractor I like to sarcastically act like his job is easy. I have worked with him, its amazing how arrogant some home owners can be, some clown thats built a deck will act as if he knows his job, guy runs a company with payroll lol
@@Baasicstuff oh, I didn't pay attention to the user name lol As far as learning to run this, other than starting it, you can learn most of the controls from this video alone, and then it just takes practice to get good lol I learned how to run one of these as a young teenager by riding on one about this age and watching the guy, and then one day I asked if I could run it, and he said if I could get it started I could drive it... Of course I had watched him start it, so that was no issue, much to his surprise! Lol (main battery switch on, in neutral, bump throttle lever about half way on, turn start switch to Preheat for 30 seconds to 3 minutes depending on temperature, and then to start until it starts up, and immediately reduce the throttle lever to idle) I worked for him running dozer for a year or two after turning 18, and then when I started working at this sawmill (diesel/Industrial Mechanic and Millwright etc), this became part of my job after getting it running, and I discovered that I hadn't forgotten how to do it! Lol So if you ever have the opportunity, give it a shot (snicker), it's fun, and you will suck at first, but that's normal! And most of the newer ones are joystick controls and much simpler to operate, this is from back in the pony motor and cable blade Era. The electric starter, hydraulic blade controls etc, are all aftermarket conversions on here.
@@ke6gwf nice, I had an opportunity when I was building my wall but it was so close to the house I passed. Looking back I regret not getting the lesson when I could
@@Baasicstuff it's probably best to start out when you have a little more space to practice, these are designed to spin rapidly, and it's a bit tricky in tight quarters, so potentially you made the right decision lol
@@ke6gwf that's cool. I do have a video of the D7E that was taken with an old 8 mm camera, so there's no sound. I guess I could put some music with it LOL
@@ke6gwf Oh okay, interesting, I've never tried that before. I'll see if I can find that old footage of the D7E this evening maybe have it on by tomorrow.
This was the "in cab" shot showing controls and such, I also have a video just before this on a tripod. I didn't have much time to be mounting cameras and setting out tripods, plus it was hot so the camera would often overheat and shut down sitting in the sun.
Power and weight I worked on a few d9g they some beast and a pig when they break down in the field Biggest engine I've ever had to work on installing the driveshaft is fun
I had to do several hydraulic hoses, some at the shop, some in the field, and they can be HARD to put on! Snort and large and odd ends at odd angles going between the transmission and the converter housing.... Lol
Ive never seen a control setup like this on a hydro unit.. mostly see those tillers on the cable versions.. must be a very early model. Great operating though.
It's an aftermarket blade and hydraulic setup, so it's possible that it is using off the shelf parts for the controls. The hydraulic pump and reservoir is mounted to the front of the crankshaft, and so the main blade hydraulic valve is up at the pump with a linkage running back to the tiller lever, probably similar to a cable blade clutch.
The blade tilt lever which is the far left lever was how the early 7,8s & 9s had them, some were also a foot pedal operated out to the left for blade tilt.
@@rossgray3070 I think this one may have originally been foot pedal for blade tilt, there was another smaller valve under the floor plate that it was originally hooked to when the hydraulic blade tilt was added 20 years ago, but then when the slope board was removed, the hoses were extended over to the much larger fender mounted valve. It was all aftermarket in any case, and the mechanic who installed the blade tilt hydraulics is still working there lol
That's the blade tilt lever. On these old dozers, Cat didn't sell them with blades or rippers or winches, or even the rops, they just sold a tractor and you could tow a plow with it or add your own accessories or implements, so everything on these has been added aftermarket or custom, rather than factory designed in. So on here the main hydraulic pump is hard mounted to the front of the crank shaft, and sits inside a hydraulic tank mounted in front of the grill, with a little bulge in a custom "grill". The main blade control valve is up by the pump, with a long linkage back to the big tiller lever on the right. Then there is a big valve body by your left toe on top of the "fender" for blade tilt. You can see the rounded thick cast aluminum cover over it behind the tilt lever and shift lever. So basically the aftermarket just had to figure out where to weld and bolt things, and how to route all the goodies through the tractor, which makes working on them interesting some times lol
You are missing something... lol This was switching a large wood shavings stockpile from expansion mode into loadout mode, and working on rounding over the tall end so that material could be pushed back to where I could easily get to it with the 988 loader with a 14 yard chip bucket and fill trucks with it. The steering clutches were having problems on the steep slope though, the pump would suck air and you would lose steering until you got back to level ground, so I wasn't able to do it like how I wanted because I had to make sure I always could get to level without having to steer! Lol So it may not look logical what I was doing, but if you could see the pile, and how we were loading trucks from it, it would make sense.
That's the blade tilt lever, the valve is under the big rounded cast aluminum cover just in front of the lever. On these old machines Caterpillar didn't make blades or rops or rippers, it was just a bare tractor with a tow hitch on the back probably. So all the hydraulics and accessories are aftermarket. In this case it originally had a slope board, and that valve and lever was for it, but then it had hydraulic blade tilt added and another small valve was added beneath the floor with a lever by the left leg, but it was too slow because of the small valve, so when the slope board (a wing that comes off one corner of the blade to cut road banks etc) was no longer needed, the tilt was switched over to the big valve and the outboard lever. The blade originally had a manual turnbuckle style tilt, which makes it a lot harder to cut slopes lol
For someone like me, none! Lol For an old one like this, it's noisy and hot or cold and windy and dusty, the controls all take a lot of physical force to operate, and you have to dance between all the controls to make it work well. Then you have to have the know how to use it to move the material that you are working with, and do it fast and efficiently without overloading or damaging the machine. Basically, it's just about the same as running a small dozer, just scaled up. In many ways its actually easier to run a big dozer than a small one, because you have a lot more power and traction, and it's a smoother ride generally. The downside is if you are trying to do little dozer work with big dozer, and you barely fit in and can barely see what you are trying to do lol Basically, you have to get on a dozer and start doing something with it, but then get better with practice, regardless of the size.
The D9G is going to move more per pass because it's got a much larger blade, but a modern D6 is going to have a faster travel speed, but it would take several passes to move one D9 blade full of material, so I think the 9 would still be faster at moving bulk material. We also have a D7 that I used a lot before I got the D9 running again, and it was no comparison, I was quite a bit faster with the 988 loader than the D7 at moving material because it just has such a smaller blade. Now, I would prefer a new dozer with ac, but this old iron is certainly fun to run for a while... Lol
Why did you watch it then? Lol This is interesting to people who enjoy seeing how the controls work on old equipment, or enjoy watching equipment in operation. You apparently aren't in one of those groups lol
Nice show of the operator view!

Awesome D9! Love that dozer! Fun video, great point of view!
Our first dozer was a D7E, (early 70's) then we bought a a D9G with a 16-foot U dozer. The U dozer would carry a lot of dirt each pass.
We also have a D7E, I think I have a video of it working as well
@@ke6gwf that's cool. I do have a video of the D7E that was taken with an old 8 mm camera, so there's no sound. I guess I could put some music with it LOL

@@ke6gwf Oh okay, interesting, I've never tried that before. I'll see if I can find that old footage of the D7E this evening maybe have it on by tomorrow.
The D9G is a 40 ton tank with so much torque!. This one looks like it was built in the 1960's and its still going strong!
Although I miss having a quiet cab and AC, this was a blast to run, just raw power and cast iron!
They made them strong

They’d have to drag me off that gem….I’d like to see how long it’d take me to level that whole lot of chips from corner to corner then back…..
I would have loved to do that, but I had to limit myself to bulk moves to support loading it out and making room for new stuff lol
