NEW SERIES H D8 CATERPILLAR POWER TRACTOR 1950s PROMOTIONAL FILM 52564

Support Our Channel : / periscopefilm
The 1950s Caterpillar film This New Series H D8 touts the new 225-horse power tractor (00:37). The D8 has been the yardstick of big tractors for decades, and more than 1,000 improvements have been made since the first D8 was built. For the new D8, engineers design lifetime lubricated tracks and test the product on proving grounds; the H Series D8 is then tested vigorously on Caterpillar’s proving grounds (02:25). The film discusses new features and improvements to design with the new Series H D8, including size, undercarriage, drive and speeds, and other specifications. Operators enjoy the comfortable deck (04:20) with increased visibility on the revamped tractor. The film gives an overview of operations from the deck (04:50), then shows a D8 undertaking a land-clearing job in Central Florida (05:34) and another D8 working a stripping operation at an Arizona mine (07:00). The new D8 is easy to maintain and features some other notable features, including the double reduction final drive gears, a new direct drive transmission, and the advanced lube system.

The D2 and D11 are the only two I have not run. I was amazed that I could do just as fine a grade with D10 as with D8! But D7 and 8 were my favorites because of the jobs they are given.

[@peternewman958]

Fluid hydraulics introduction is probably the single biggest major improvement to any machinery in any field. Diesel engines would be the 2nd . But hydraulics simply allowed a massive increase in what could be then achieved. As both an Automotive Technician and a Mechanical Engineer when you stop and think about what operations in a huge range of engineering fields are done by hydraulics then try and design a way of doing it without hydraulics.

[@thegreenerthemeaner]

That is almost a hard call. Diesel engines had far more torque cubic inch to cubic inch, burned way less fuel, lasted far longer between overhauls. Hydraulics brought more precision and ability to perform a function in a way that power mechanical could not. Blade tilt? Ripper angle? Hydraulics came around almost the same time as diesel. The hands down winner in the earthmoving arena was the diesel engine. Several old dragline/clam rigs were repowered from steam to gas to diesel or straight to diesel. Couldn't quite make them hydraulic as easily as the later ones.

When i was a kid growing up on a small ranch my father would trade work with the neighbor who was a cat skinner he would show up and set me on that Caterpillar with him operating it, it was amazing.

Hi They would finally catch up to the Hd19,20 and the 21 that had all the power assisted steering clutches,torque converter brakes and sealed rollers that the 19 had in 1947. Thanks for listening!

The 8-H was a FINE machine! Ran one a lot years ago and they'll load a 631 pan in a jiffy! Thanks, Periscope!

[@MarkSmith-on5gg]

was my favorite until the R models came out the R was the best. but I loved my old 8H

[@Grungemann]

Ran one when I was 7 years old pushing 621 till I was 8 then I was put on a 631B with no canopy no brake had a lot of close calls to getting killed but I'm 37 years old now dad's died 14 years ago miss the hell out of him he was my hero I ran 491 pull type with D9 pulling 63 cubic yards direct drive transmission when I was 10 all summer .ts14 euclid twin 471 if I had a time machine I'd be there now! .............

Love the FLECO round canopy. It gave a Cat such a cool look. the D8H really came into it when they introduced the Power shift transmission. What a beast.

[@tommyhatcher3399]

Not my favorite vehicle but definitely my most appreciated. Growing up I saw normal Cats everywhere, giant factory on wheels Cats, and countless Cast rotting away in the woods. So much variety, too, back in the day. There were about 30 normal Cats creeping around my neighborhood looking for work, and collectively they probably had every year of Cat on their ranks. I was a boy in the 80's and you can bet there were still some pre-historic Cats around.

[@kalvinlabuik3366]

The best thing about Cat motors they have a good constant bottom end power two I like the roar of that Cat engine working hard loaded or cruising lite and empty it's never changes yup I a Caterpillar man I liked the 955 traxcavator model never had the pleasure though to operate the 977s or 983 lol but I did run the little D6 and D-7G fell in love with the D-7G 3306 power ran the 621B awesome machine yup I am Cat guy lol 👍🏽👍🏽

[@youngmike8645]

I learned how to operate a dozer on a D8K. I am most certainly a CATerpillar man. I miss the old D8ks that engine (D342) would never lug down it would just spin tracks. It was only like 220 horsepower but the torque was INSANE! Grew up around CATs and operate all different yellow specimens on a daily basis. CAT diesel power is the best type of diesel power.

[@pinetorch8181]

If the engineers could have seen the D8T back then after they built the D8H, they would be amazed!

[@digndurt6936]

You can't best these old machines though!!

[@tyfrank3427]

In 2066, 60 years after the first D8T was introduced, we'll see if there are any still running. I doubt it due to too many electronics. Mechanically, the D8Ts are a solid machine, but the electronics are definitely a weak point.

[@mikecubes1642]

@@tyfrank3427 thats why they put electronics on them now so they will break down faster and need to be replaced. all that computer crap is not needed on equipment

best tractor ever built

[@stevebrygadyr1675]

Great video! When I was a young heavy equipment operator, I actually got to operate three different 8Hs. Thet were the later models so they all had hydraulic blades. One of them was a direct drive pulling a cable scraper. That crawler was impressive how quickly you could load up, gear up, and go spread. The other two I operated were just for dozer work. Both of them had a single shank ripper that was hinged so you could actually rip while turning so ripping straight in heavy frost was easy. I really enjoyed operating those units. This brought back good memories. Thank you.

[@J.Goncalves55]

Parabéns PeriscopeFilm, ótimo video sobre o D 8.

[@bryanhiland8972]

Thats a 35A or 36A it’s direct drive The 46A was mainly power shift

[@tyfrank3427]

The 35A and 52A are torque converter drive, The 36A and 22A are direct drive, and the 46A and 68A are power shift. The 35A, 36A, and 46A are American machines, and the 22A, 52A, and 68A are the British counterparts. This video is 1958 as the powershift came out in 1959. The 46A took over and the torque converter drives were eliminated in 1961. Due to lower production numbers of direct drives, the 22A model was eliminated around 1970... At the end of production in 1974, only the 36A, 46A and 68A models remained and were replaced with the 66V, 76V and 77V D8K tractors. In 1965 and 66, significant changes were made. The 270 hp machine came out in 1966, and with it came many improvements.

[@bushwacker3292]

Awesome video 👍

i have one of the last ones built still runs strong no plastic or computers u can fix it with ease

Nowwa days its.... Oh no! the ECM shut everything down, right on the slope of a mountain or in the bottom of a new pond and rain on the way!!!!!! now whatta I do???? got to call CAT [Call Another Technician] "Oh....well were three hours out, oh and dont forget we charge the time we leave from the shop to the job site" CHA CHING $$$$$$$$$!!!!!

[@josephrivett6158]

That is why a person is better off buying an old machine, spending $$$$ on a complete re manufacturing, and actually save/make money.

[@Only-one-life-68]

cletrac 12c Bang on All the manufacturers have got greedy. Must of been great working these old machines The only thing that’s improved is the driver comforts The rest is just poorer quality and to much environmental things going on..

When a Cat was a Cat

[@jamesanderton344]

Great history Periscope....where are the hydraulics? Cables lift the blade?

[@jimharvard]

all dozers used cables to lift the blade up through the early 1960's. there was no down force to the blade, only gravity and the weight of the blade provide downward force. the cable blade systems were pretty ingenious in that the winch on the back of the dozer provided the pulling force of cable that ran along the right side of the machine to the front "idler pulley" at the top of the radiator which then fed the cables down to the blade. the large "swing handle" beside the operator ran the winch "back and forth" which raised and lowered the blade. naturally, the cable system was no where as efficient or accurate as when hydraulic cylinders took over for lifting and "pushing down" on the blade. but because the front blade was so heavy, the cable system worked well in its day.

[@thewidower1]

If you paid attention to the video there was hydraulic controls on some of those machines. It was available even back then as an option but it was expensive. The cable control was thought to be adequate at the time. They weren’t to concerned about side cuts or slopes back then. A good cat skinner could always make it work.

[@Species5008]

Wish they would do some of the newer equipment likely this.

[@peternewman958]

Its funny but watching these old films reminds me of how little attention was paid to the finer details of surface finish and paint back then. I remember our machinery looked better after they had an overhaul and repaint than they did when my grandfather bought them new!!! Nowadays you would have trouble selling at huge discount these machines with their poor finish. People want better quality now than back then. Its all related to the cost now.

Cable was still available as an option up to the late 60s if not early 70s.

[@daryllitke8133]

@@wailnshred my dad had a 46A (D8H). It was serial number 10695, a 1967 model I think. It was originally delivered as a cable dozer but then converted to hydraulic a few years later.

[@MarkSmith-on5gg]

you could get it both ways then

[@tyfrank3427]

You can get cable on D8Ks too. Even cable dozers were optional, but every D8K I know of with a CCU was used for pulling scrapers. The early Hs with hydraulics had the hydraulic unit in front of the radiator.

Only 225HP? How is this possible? I know nothing about those things, but seams a bit low to me.

[@rossgray3070]

Power shift ones were 235 hp and later models went up to 270 hp, the K model were 300 hp.

[@yogevbarshavit]

ross gray here is why it sounds so low to me. My car has 327 HP and weighing less than the dozer. This is why in my head it doesn’t make sense, but I’ll take your word on this.

[@Only-one-life-68]

Yogev Bar Shavit Your car may only be a 4 cylinder 2 litre engine These ole cats were 6 cylinders with huge litres Also been a diesel the low down torque is unbelievable as they only rev to may be 2600 rpm.. Turbos were a huge help also but turbos consume fuel..

Only one life thanks!

[@iBackshift]

@@yogevbarshavit Those engines ran full throttle at 950 rpms (1250 lbs torque) and pulled/pushed hardest at 650 rpms(1500 lbs torque). That D8 engine made about 45hp at idle (325rpms @ 720 lbs torque), more than twice the torque your 327hp engine has at 4750 rpms.(350 lbs torque)
