Im just setting here enjoying the sound of the old girl!! spent alot of time on a 9g and a 9k. retired now and i miss it. wish I could find an outfit that would let an old fart work part time, but I still enjoy the videos guys keep up the good work boys stay safe.
Went on a service call a few weeks back. seen a fenced in yard with a d9g and a few d7s and 8's all pre '80. old man died and the family has done nothing with all the equipment. like they pulled them in after a job and left them.
Those old D9 G models never run high RPM, if you have become accustomed to the newer hi RPM tractors you will be mistaken on how slowly the 9G operated. 1200 RPM makes a reasonable speed , and I have heard of some setting the RPM back to 900 to 1000 which I feel is too slow if hard work is being done.... . I have worked many shifts on those things in the cool night air, you can watch that stack get a bit red and have a fair amount of red in the exhaust smoke. Fine tractor
So was that the muck you cleared out of a pond? OR ..the pond had filled with so much silt and erosion that was all that was left? Eh whatever the case awesome vid.
Love the videos but you need to take the little lever by the steering levers called the throttle and pull it wide open. That's the way that engine is designed to run, not 1400 rpm.
+Dieselman8v92 looks like its running fine, not wasting fuel by speeding up the engine a few hundred revs and gaining very little productivety by doing it , black smoke and high revs is like chucking money in a fire, also prolonging engine and machine life.It don't earn money having its engine overhauled in a shop. Its like the tortoise and the hare story
Well, engines have changed a lot in the past 100 years. As the the diesel in that old girl, it was designed to run wide open like all other industrial and Ag diesels. It will consume less fuel and actually put less wear on it when operating it where it was designed to be ran. Now for your typical gas engine, your statement would be correct.
+Dieselman8v92 Can't see how it would use less fuel at higher revs, my mate has two D9G and I work on 3300 hp diesel engines every day which have computer controlled engines so you can see fuel rate consumption in real time.The van I drive has a fuel rate monitor so I can instantly see MPG as I drive. I can understand if it was constant load, like generator sets. But dozers are not always constant load. Black smoke is over fuelling and wasted fuel and can wear out engines by the not propery combusted fuel washing oil off the bores, fuel diluted lubricating oil etc. , this D9 is running clear as it should do. Part of my job is taking engine oil samples for testing
I know what your saying but it all comes down to how an engine is set up. For example a new diesel engine in a truck is designed to run from 1800-2000 for best power and economy. An engine in a industrial or Ag vehicle is designed to run at full throttle for the best economy and power. An engine running below its power band with a load will work harder, use more fuel, and get hotter than when in its power band. If the engine is just running at partial throttle with no load, then it will use less fuel obviously and thats fine. Take this D9G for example, it was made to run wide open for optimal power and cooling conditions, working it at half throttle can make it get hot, and build up carbon. It just comes down to the set-up of the engine.
I love seeing the Old D9G in action!
Thanks
Your old man lives in a heaven only a few people get to enjoy. Wish I was him.....Enjoy
Man thats my favorite machine out of all the cats you guys own i want that one more than any other.

I always enjoy the videos.
looks like hes a vary good operator not trying to hurt to rush or hurt his cat vary good i would hire him
FordWoman_4 Xxx damn near impossible to hurt those old Cat's. they were built to last back then
He is under revving it though, which is causing more strain on the engine. A few more revs would be much better and easier on the old girl.
It sounds amazing

that old girl still has a lot of juice in her...great video.

I shudder to think of shoveling out those tracks.. wow
Now that's a big citty.
Max RPM's on most dozers will be 2300 at the very most. They usually average about 2k RPM at full throttle in gear give or take 100 RPM.
how do you move all your machinery
why is the D-max getting parked? (just curious)
why don't you drive it? just like the 12 valve more?
D9g:-)
I thought the flatbed Chevy was getting parked?
nice old girl
Why are you not using one of the scrapers for this job?
Bummer :(
I envy yall soooooooooooo much its not even real.
What kind of RPM is that bad boy doing?
...1330 rpm...apparently the D9G was turned up from the 1200 rpm the old naturally aspirated D8s used to turn...
So was that the muck you cleared out of a pond? OR ..the pond had filled with so much silt and erosion that was all that was left?
Eh whatever the case awesome vid.
Don't need a ripper to clean the pond
Go help him clean the tracks
My dad will be driving a vehicle that's smaller and cheaper to operate.
It will be parked very soon.
sounds like she needs a bit more fuel. turn that pump up a lil. watch her go
Dan Lacey seems to be doing fine as is
think its time u clean your under carrage
Good job for a guy with a degree

A Cat tractor with an elevated drive sprocket would look even better
