Year's ago I worked for a hard rock contractor who always ran old iron. 1 of those was a 1958 D9H No ROPS or FOPS, no hydraulic either. It was a "cable dozer" that used a 2 cylinder gasoline Pony motor that was used to start the main engine, it's starter was the size a Ford V8 gas engine starter. You started it, then once it was running you engaged it to the main engines flywheel, letting it spin the big diesel engine as you slowly fed it fuel. It would then chug to life and kick the pony motor out. On cold mornings you would spin the big Cat engine for 2 to 3 minutes so it could build enough heat it the cylinders by compressing just the air ( which is how they run- compression ignition) before putting fuel to the injectors.
Good video I'm a very proud owner of a ex us cat generator fitted with a cat D315 power plant same as fitted in the D4 this power plant is still working in its arignal working clothes and the generator is all caterpillar All new parts for service and repair still can be perched from finning cat UK this just shows how good these old caterpillars are and still out doing a 12hr days work at the vintage shows today Brilliant classic cats will always live on
My dad was Army Corps of Engineers building airstrips in the Pacific during WW2. He was a big fan of Caterpillar equipment (dozers, graders, etc). I was a US Merchant Marine engineer and found Caterpillar emergency generators on ships going back to WW2. They were even seen on later (1980's-90's) German ships I worked on.
The RD models stood for Rosen. Art Rosen a Caterpillar engineer in the 30's and 40's was the designer of the D9900 engine that was the first diesel placed in a Cat track type tractor, in honor of his work tractors were designated with the RD cast in radiator tops from1935-1937.
May early model cars with old flathead engines could put out 60hp, but they couldn't run a ten ton tractor. Let's hear about the TORQUE these engines were producing. Thank you for these videos.
It's not just the torque, but also the beefy components that allow them to run at 70 to 80 percent of rated horsepower all day long. Cars only needed big horsepower numbers to get up to speed or pass other cars, cruising along at a steady speed only took 15 to 20 horsepower. Similarly, starter motors to crank the engine only became popular when the manufacturers finally realized that the motor didn't need to be developed for continuous duty, but max 30 seconds of use.
I am surprised you didn't mention the Caterpillar Semi Truck pre WWII they only made 4 trucks, I wish I could remember what motor it had. I worked on one of them back when I was in College (1979) getting a degree in Heavy Equipment Mechanics. It was the largest Semi Truck of it's time, dwarfing all other trucks.
Excellent and informative video! You must have scoured RU-vid for some time to accumulate footage featured here. I recognize quite a bit of the vintage footage, as well as the short video of the Diesel 60 being started up. That engine was listed for sale some time back by an equipment dealer in NY, and this video showed that it started easily and ran well. The tractor is now fully restored (there's a video out there of it at a show). Quick note... Haven't watched #2 yet, but the the D13000 replaced the D11000 in the later RD8 and D8. The D11000 in RD8's is pretty rare, at least in surviving machines. I've only seen one or two on RU-vid, with the majority of D11000's as part of a genset (diesel generator), at least in surviving units. There's a few iterations of D11000's as well, which can be identified by the type/position of the air cleaner/intake, as well as the intake and exhaust manifold type/configuration. The D17000, as well as being a marine engine (new to me), was produced as an OEM diesel for locomotives, draglines, excavators, gensets, etc... A few industrious individuals have retrofitted them into D7's and D8 in modern times and I've read that some dealerships "back in the day" offered that service to customers, though I've never seen any photographic evidence of it done. There are several videos of "modern" D17000 retrofits here on RU-vid. Makes for a "beast" of a tractor! Again... Great video!
My first ride in a rig was 1978... a mack v8. I declared it the greatest rig engine ever. I asked why all rigs are not v8s.. and it is due to the tracks of dozers and road building equipment needing a 6cyl for width. They could make a v8 of the 90 degree kind and be most welcome today. Mack is the only one that did something real, and they went away. 41 years of family trucking.. change my mind.
@@sheepdog271 the real shame is that the "then owners" of Mack trucks were squandering the company's assetts and mismanaging things. It seemed they had a total disregard for what was going on in the industry. That's what led to the sellout. The other part of that shame was they sold to Renault. Once Volvo took over, the product got much better.
Yes, a good video - with so much detailed information it was difficult to comprehend. The pace of narration could be much slower with supporting text for model and engine details other wise a great American story. I hope this helps. Cheers
What is not mentioned here is that over the road diesel engines were not really possible until fuel injection systems could be made small enough. That happened about 1925 or so,and the company that manufactured the buses for London Transport pretty much pioneered the technology. AEC I think it was. So Caterpillar was right up there following a new technology in an application different from moving buses over paved roads. A smart thing to do,continuing research until sure of customer satisfaction rather than spitting out a product in a hurry and hoping for the best. Cats were never cheap to buy. Antagonizing people who have spent much money is never wise. Good for them.
@@wilburfinnigan2142 Oh Wilbur,Wilbur. The bad Catholic.The despicable Irishman. Anything English is the spawn of Satan and must be hated. The language you used to describe Winkle Brown the test pilot who is a better man on his worst day than you ever were on your best day. Utterly despicable. The seven deadly sins,Wilbur. Envy. And the others.A brave man risked his life,using competence Wilbur. For abstruse knowledge. And you hate him for both. So your Irish buddies and relatives encourage you to troll . Go away Wilbur. Find a hole and fester,like Gollum. The One Ring is not for you. Bravery is not for you. Decency is not for you. Merely because you can type does not make you a man. There really are better looking maggots than you crawling in the eyes of a dead dog,Wilbur. Go to confession,admit your sins and try hard to be a better human. Very difficult for you,but God always gives us the choice. To be petty and squalid and evil or to strive for decency. Go away Wilbur. Try to be a man your mother could have been proud of.
@@garethifan1034 Yep. Think I got under his skin with at least some of that. And a good thing too. Decent people making decent comments ended up shocked at his unprovoked gutter language. A gutter mentality with a gutter mouth. As you say,his Duh stuff and other crap are junior high mentality. Well put.
@@nztrucker1542 likewise mate, I fix them all now instead of peddling and I gotta say I don't have to put a spanner near a yellow engine anywhere near as much as the other breeds on the loose.
And underwater. Check out Million Dollar Point in Vanuatu. The US Military dumped heaps of gear there at the end of WW2, when the island govt wouldn’t agree to pay for it. Dozers, forklifts, trucks, building materials etc. I worked as a dive guide there a couple of times in the very late 1990’s.
I just learned all this 😂. I just finished my first semester in the CAT ThinkBig program. I already had a lot experience of experience with them but I figured I’d go get certified.
Honestly I never was too certain about CAT Corporate after just learning about Fabick Cat and all the newer stuff. I know I'm in my second year of the ThinkBig program and I'm still learning all of this. It's really unique to know how groundbreaking Caterpillar really is
@Saint Fifty One I had an olds Tornado 1979 with the 350 diesel, a powerhouse it wasn't, but it was great on fuel mileage. I was able to get 21MPG from mine. It would bury the speedodometer too. Of course the speedodometer only went to 85. It was dependable even in 10-12 degree weather it would fire right up after 15 seconds of glow plug on
Please... Detroit Diesel (aka GM) built this country. Before anyone knew what a Cumapart was Screaming Jimmies were powering military equipment, interstate road building equipment, and pretty much every type of road tractor known to man. The only people that think Cumaparts are great are light truck users.
@@prevost8686 We had one or two truck manufactureres in the UK that fitted the E/N 14 to their trucks..and apart from poor fuel economy they were fantastic engines that never missed a beat all running at 44 Tonnes (about 97,000lbs in old money) nowadays they are no more..pity. They were beasts
they are only available outside the USA and Canada because of our environmental guidelines , the newer detroits and cummins engines will never last like the old ones because of the restrictions put on them .
@Dez Nutz the emissions equipment on the new diesels reminds me of the early 70s strangling gas engine emissions equipment. But in the case of the diesel they stopped development there and said it's good enough.
Jeff Frearson - Truckers may not like DEF, but we all have to breathe. There are more people who want to breathe clean air than there are truckers. A lot more.

See now the RD series broke into two series: The D series (Diesel, D2, D4, D8 etc) and the R series (Gas, R2, R5, etc). My hypothesis is that they were called RD because the diesels required a gas "pony" motor to start the diesel. Why they chose R as the designation idk, just fruit for thought.
Fascinating.. let’s face it .. there is nothing in our lives that doesn’t have a diesel component.. remember that next time you buy a box of beer .. diesel is even used to make it .. go away you greenies
Well, in the beginning, they partnered with deere and built engines that couldn't be started without a gas engine. Then they built indirect injected engines, that the heads were cast entirely from tiny cracks. Then they built the 3406, which was good. But also a bunch of v8's, which were not. They built small electronically controlled engines, that were worse than their v8's. Then they got in bed with perkins to brand little junk engines with poorly sealed heads and inadequate cooling, with the cat logo.
I was always a cat man until I got my 1993 379 with 600 horse detroit 60 I get better fuel mileage it will make cat run away with its tail between its legs
