CATERPILLAR D8

[sonick808]

no guts no glory!!!!!!

[justfoo2006]

Looks like a guy doing a demonstration startup at an auction yard actually.

[blanegray1]

they should stick one of those plows on the back of a buggatti forget the air brake

[Arabhacks]

The correct way to start an engine with a pony motor is to pull the fuel kill and engage the pony motor, allowing it to spin the engine for a minute or so, the cooling systems are connected.

The correct way to start an electric start diesel is to start with about half throttle and as soon as it begins to start drop this to idle.

After about a minute go to fast idle and maintain this until the temp gauge begins to rise, at that point restore half throttle until temp becomes stable and than normal

[acres90]

24 liberal democrat tree hugger dislike this video

[DragoonA26T]

Dip shit should let her idle and use the glow plugs............

[bakedsugarcookies]

@DragoonA26T It is probably not his machine so he doesn't give a fuck. 

[gusthedriller]

i think i can ....... i think i can........

[NesteHukka2]

Sorry about duplicate message :( Turbocharged diesels must be held nicely when they start, but I don't believe in it that overloading fuel can cause damage. If unburned fuel accumulates into cylinder, it only step by step raises compression pressure, so it eventually must fire up. Long before possibility of hydrolocking. Ringlands take hits from huge turbopressures, cause powerstroke can simply be too much for stock piston. ...and Diesel... Normally aspired 5 mins idle before run, turbo 10mins

[NesteHukka2]

By the starting sound, am I right that these are direct injection type diesels?

[gusthedriller]

the only thing better than that sound is the smell !

[bigblocksrock]

that chatter cat sounds wonderful cold lol

[jordi2822]

ec e bagual!!!!

[jozzie2000]

lots of arm chair experts on these kinds of videos hahaha you guys are a real joke.

[SquawMtnD4G]

You got to love the clatter and clank of an old cat.

[1206fan]

bad ass ih 1206 baby lol

[DeserTBoB93535]

Someone doesn't know what they're doing. Overfueling at cold start's a great way to yank a sleeve or at least score pistons. Keep that fuel DOWN until enough heat is generated to fire off most cylinders. Even then, keep the Rs low until it warms up.

[NesteHukka2]

@DeserTBoB93535 Is this fact general rule or model specific? I have small diesel tractors from the seventies (David Brown 996 and Leyland 270), and cold starting these at winter there is button on injection pump that when pressed forces even more fuel into cylinders, that it would be on normally full throttle. It is a feature for cold starting in hard conditions without prewarming possibilities.

[1973RoadRunner440]

Definitely shoulda let it warm up for a while though before he decided to pour on the fuel. That wouldn't fly with me.

[fabianoblues]

[3793939]

Sounds like a CAT Clatter And Tick. Buy a Komatsu at least you will have a real piece of equipment.

[1973RoadRunner440]

@3793939 Thats the way caterpillars have always sounded incase you haven't noticed. We had a PC200 piece o shit for a couple years and then traded it in on another 320 Cat

[Bag0fRats]

@1973RoadRunner440"Clatterpill­ars"

[1973RoadRunner440]

@Bag0fRats Yup. I like the way they sound though. Like the 1693s or the 3406s.

[Bag0fRats]

@1973RoadRunner440 There's a good 1693 video on here, I think it's in a Kenworth

[76target]

@1973RoadRunner440 you cat people would bleed yellow if you got acut

[1973RoadRunner440]

@76target Maybe I do bleed yellow

[billesau]

He'd be kickin' a tin can down the road if he worked for me! Unless he's running synthetic oil the bearings will be scored.

[Skid00everest340]

breath this nature haha!!!!

[mountainhunters]

i had a d8k without as cab over here in australia, loved the thing

[generationll]

Mais,It has a 1,246 cid D346 while the 983 has a 3406 at 893cid

[JBurton00031]

YEAH! CAT POWER

[321eriko]

injection probleme???

[AUDIOBARN69]

Didn't start clean

[mais842]

great machines powered by cat 983 engine?

[generationll]

It is indeed a 300hp 71,000lb D8K

[50mi55ile]

sweet music lol ,looks like a d8k

[HwkyPlrs]

i just came 3 times

[TheFordguy89]

Take that Al Gore

[ToonandBBfan]

Listen to that old girl roar!

[irssssss]

i have an old Cat D6 and i aint gettin rid of it ever! i will even see if i can get buried with it. they are such a great machine.

[aligoraro]

D9 H the best machine ever i onwed one since 1996 and i have never spend a penny on it apart from fuel.and itt working in libyan sahara tuogh conditions

[upallnite88]

Why would you put those new decals on such a beautiful, old machine?

[amigoamid]

I bought a D8K rebuilt certified dozer and evryone was talking about how clean does my machine look .... when we got to the field aftger 1 hour of working the chocking news came to my office the transmission is gone !! that was the certified dozer ..... too bad that it is working overseas and i can not get it to this fucking cat dealer who rebuilt it and certified it !!

[ksmitty79]

probably a certified rebuild. Get a whole new serial number and warranty. For about 1/3 less then buying a new one

[nachos1990]

thats a nice cat probably took alot of work to restore that

[WVhoeman]

not if it was taken care of

[nachos1990]

Yah but the paint at would not be even close to that nice even if it was taken care of

[WVhoeman]

wel your wrong and right but paint isnt nothing

[catskinner619]

Its called a putt motor, runs on gas and the putt motor is what starts the diesel

[xdawg51]

its not a pony motor its just where its cold

[generationll]

Its a 300hp D8K with a 1,246 cid D342

[scpd613]

long live those old cats.....

[Strogenforcer]

Ah looks like an old D8-K

[hasolo1]

I love this machines

[greyhoundjake]

Is this an indirect-injection engine?

[VikesBolts1228]

This girl has to be old. Early 80's maybe? Haven't seen a non hi-drive anything over D6 since early 90's...

[ChewwGrizzly]

Now thats a nice piece of machinary there

[rotundrooster]

Just airlocked a bit,not a biggy.

[generationll]

This 300hp D8K is over 30 years old

[UnderclassFarmboy]

if you ask me, it sounds like its knocking realy bad, almost like my dads backhoe when he spun a bearing on the crank

[hwoods01]

Its "kocking" because he is starting the engine with the pony engine. The operator is using the pony engine to spin the main engine.. The knocking you hear is some partial firing of the cylinders. at 0:41, the main engine warms up enough to finally fire on all 6.. and thats when the "knocking" stops..

[mstaff657]

there is no pony engine on that dozer

that is just a high compression engine.

sounds like it has been sitting for a time.

[ihaveairlockers]

After it started it sounded fine and strong

[mysubsbang]

yeah but the old ones all sound pretty sick when you cold start them like that. they will hurt it someday poor baby lol

[777worldliner]

dont tell al gore!!

[danantnap]

that's a nice cab! Nice dozer!!!

[drfeelnothing]

A new dozer....LOL.....thats black smoke bud,not blue.....have to wait till she warms up first...looks like it is starting to clear up after a few secs

[trappercv935]

Utube...........Tecnocons Robot CAT D3K.....

[stealthbomberjacket]

gee that's alot of smoke for a new dozer

[jjthehick2]

We have a Old Old D7 Runs just like that The thing is allot more of bitch to get started but once it running it's a tank

[alvinox73]

employee revolt in France !!!!

[briancgaz]

his car and pc probably in the shop a lot...rev the car up and load everything on the pc booting up. Good piece of machinery on it's way to the scrapyard

[kunon7]

kurwa ciekawe ile to pali??

[honkey450]

why would you waste money on paint and stickers that old piece of shit?

[sornbergerfarms]

oh well its probably not his machine and it probably has good insurance

[Vicsonvee]

You should let her warm up a little bit before you rev. the engine that high.

[crashly75]

considering where the hydraulic tank is,

it's a D8K

made be a it needs just TLC

glows replaced or electrical work.

[d9oper8tor]

Awful lot of geniuses on youtube,they would probably shit their britches if they ever saw an old cable rig that had to be started with a pony motor,that 8 was just doin what cold start motors do,,,,heat them glows up would help,,,,but shes still gonna clatter

[polompon1]

It's called,,DIESEL KNOCK,,perfectly normal on this and many engines like it,,,,so just stop bitching about it eh,????

And to catskinner,,77v,,if it's,,out of time,,how come it goes,,in time when it warms up a wee bit,????????

Way too many clever people on youtube these days man,,,that have no clue.

[gtsbloke]

thanks for clarifiying what i just said.

[gtsbloke]

As a CAT technician i can definatly say that the so called "slapping" is actually Cold Diesel Knock.

There are no glow plugs on this machine, it fires on heat caused by the compression of the fuel air mix in the cylinder alone.

And Catskinner is correct if ti was the pistons hitting the cyilinder walls you would find that it would suffer a "Cold Seizure" very nasty

[Catyella]

That's a D8K with a D342 engine and they DO have glow plugs....like catskinner said, they either aren't working or they didn't give her enough heat.

[gtsbloke]

yea mate thanks i know what it is.

all the D342's that i have worked on don't have glow plugs, and a see no reason that this one should unless it was a factory option for cold climates.

[Catyella]

Well I live in a hot climate mate...and every D342 I ever operated...(D8H and K )had glow plugs.

[bugsier5]

as a so caled diesel specialist you would agree that whit use of a preheater (or glowplugs)

this engine wil start a lot easier!

[movefart]

in my opinion it looks cooler the way they did it not to be rude or anything

[bugsier5]

whell it's an old cat so who cares , When the run the run!

[mysubsbang]

that one needs it lol dont sound to healthy at start up

[startup0]

look like we have some 23 year old punk kid that knows it all

[KZ55083]

looks like it dont it buddy

[redroadhammers07]

I bet that thing would snort like a beast at idle,I wonder how big of a snort you could get before stalling it?

[Poszukiwacz86]

Bad mofo

[cowbubbles]

my dad has had at least 10 of these dozers

[constructioncartoons]

I take it this was rebuilt?

[1majorgearhead]

listen to that thing pur it is sweet

[badvavles1]

listen at that bitch puttin,that mothafucker sound like sombody put water in the fuel tank[sugar] heeeheee

[tripster9]

its a turn over presedure its not even running yet when its clanging just turning over

[badvavles1]

man if you dont turn that ragney piece shit off[heehee]

[A1972LS5MAN]

Ran one exactly like it before i got laid-off,still love that sound though its music to my ears!

[d9oper8tor]

amen brotha,love that old work horse iron.take one of these newbies out of a cabbed machine,,,,put em out there in the cold and the heat and the dust,runnin that hot ass iron in the summertime and freeze ya doodads off in the winter,,,find out whatcha made of!

[A1972LS5MAN]

Try runnin one in 120 degree arizona heat in the middle of summer! you learn that theres better things to do for a living,but i still would do it again any day!!

[generationll]

This is a 300hp D8K that was introduced in 1974.

[CatSkinner77V]

actually introduced in 1973. starting with powershift serial number 77V00001 and the direct drive was 66V

[bunny27059]

CatSkinner77V

I agree with most of what you say, being an old Catman myself. But......77v made in USA, 66V made in Udingston, Scotland UK

[jdeerem]

that cats got 1 or 2 oval valves ( dont remember the technical term) in which when you start it up it sound like its missing do to the piston being oval instead of round, after you worm it up it sound right.

basically the piston shrinks when cold and expands to correct size when it worms up, you can tell in this here cat cuse it sounds like it missing when it fires up and sound good when it's warm

[CatSkinner77V]

ummm no actually, That machine has some problems, either the glowplugs don't work or its out of time. They take awhile to fire up because those are pre-combustion engines. they have a precombustion chamber where the diesel fuel atomizes and it needs heat to ignite. it has nothing to do with oval pistons or valves?!?! are you retarded or something? valves don't go oval, they wear out and loose thier seating if anything.

[jdeerem]

umm no valve do not get "oval"

i ways saying the piston the piston "shrinks" and is smaller and hits/ slaps the cylinder wall and make a sound like that( a newholland chopper did it at my uncles farm)

when the piston heats up it returns to its normal size and runs as it should

i do agree with u on the valves loosens there seats or wear

i think it would be glowplugs myself and you can clearly tell that think has been idling a bit

[CatSkinner77V]

haha you really are retarded the amount of space that a piston shinks and expands, never in a million years would there be enough space to make a "slapping" sound. and if you do hear a "slapping" sound best shut it off before it comes unglued bigtime. That clattering sound you hear is misfiring and possibly lifters clicking because they have no oil pressure yet. thats the only sounds you might hear. if a piston was truly slapping around in the sleeves. it wouldn't last very long,.

[jdeerem]

the slapping only need about 5 thousands of an inch which can be easily gained

[Markmeblablabla]

now with acert technology!

[justinappleton]

ive ran a D8K with the plow for burying fiber optic cable. had the plow chute on the rear and the reel rack on front. it was on old 70ish machine but it was a tough machine

[Entertainmentcenter]

What year was that cat? Was it a '62?

[thefarminkid8760]

man let it warm up a little bit and plug the block heater in

[mikxr]

was that injector knock?

[GoldenRatio]

Sa-weet! Cat D8s are great.

[gfpd2722]

sounds just horrible

[carlos9939]

verga pa q sepais :S ..... debe ser nuevesita la makina esaaaa xxxxDDDDDDDD

[wolfshadow666]

you think thats horrible you should hhear my d8

[ocram12345678]

fantastic d 353 engine

[TopGun11980]

She a smoker, Gotta Love that diesel

[d8h2u]

I owned a 2u and 46A, both had pony starts.

Although it was time consuming dealing with two engines on a start, I had no problems on cold starts.With the compression release off, I could get the diesel side warmed up,oil moving,compression going, then throw the compression release on and bingo, easy start.

[GreatestSongs]

Great vid!

[baggu250]

Thats a nice D8 there.

[shovel950]

Thats her throat cleared, now strech her legs!!

[DeLong95]

nice

[dankcorey2424]

the old d models

[dankcorey2424]

the d models start on gas to warm up then they switch it to diesel.

the bearings are NOT bad

[xdawg51]

no that is the old d models actually wasnt just the d models but almost all of them. this as someone has said before looks to be a late 80's model which someone used either to start the engine any diesel will knock after sitting for awhile because there isnt any oil in the cylinders after it has sat all the oil drained back into the pan and bam there it is that explains the knocking.

[makanusa]

q lo mpario

[gslice2120]

sounds like an ether start to me

[dozerdriver1962]

heck man ya got er goin let her be :P

[mozebasic]

nice bearings lmao.

[therealdrbyte]

heard of warming up? lol

[themattster1991]

Don't you feel like whacking the guy upside the head with a hammer for not warming up the machine? The engine needs to warm up to operating temperature and build up oil pressure. I would warm the machine up for about 20 minutes while doing so he should be doing his inspection and shoveling the swingframes while warming up the engine.

[therealdrbyte]

perhaps that wasn't an absolutely cold start?

[mshawme]

You woke the old gal up, now what? She is ready to go to work.

[finegradefrank]

yeah mybe early 80's ,was running a d-8 back home in west virginia and it was a early 70's model.ran great for and old machine.went from that to a new d-8r,now that is a sweet dozer

[crysaxo666]

explosionssss

[rednecksinspace]

Cold on gas, hot on diesel?

[rtparx]

To answer MrFoxman360's question, it probably an 80's model, but the D8 is still in production, & to devilwinz666, its where u would connect the blade. I use 1 like this where i work, it just has no glass or doors.

[MrFoxman360]

Anyone know what year this machine would be? It looks fairly fresh, but I thought the D8 was an older model.

[devilwinz666]

wats on the front? weight?

[mailman747]

Nope, there's just no blade on it.

[marshallvalvestate]

haha i laugh at ppl that argue on youtube LOL

[b75mackray]

music to my ears

[robby844]

it sounds like that because they used ether on the engine.

[catscraperman]

the only reason she is knocking like that is that the dude in the seat never preheated it long enough. I have a similar D8K with a d342 in it and if you don't glow it for 2 minutes it will not hit smooth for like 40 seconds of idle.

[Fentanyl3]

I'm amazed at the sheer number of people that obviously know nothing about cold starts and diesels

[Dirtbikeracer250]

another reason either is bad for engines is because it will bend rods

[robby844]

finally somebody i can talk too

[ZzDe0]

You make me laugh...

[cummins595959]

its sounding loud because some cyliners are not firing cuz of the cold air the air in the cylinder has to get over 750 degrees before they fire rite and either is bad for engine cuz it exploseds faster than disels and the engine is not made for it so it brakes the rings and then they lose compression thats is also how they get addicted to it

[tpvalley]

A reason ether is bad is it washes oil off cylinder walls, the lack of lubrication that results causes excess wear, maybe breakage?

I have noticed that it tends to make engines lose compression.

[cummins595959]

sorry for making a little spelling mistake no need to get so fucking upset

[ZzDe0]

Take your Canadian flag and pound it up your FUCKEN ASS!

[Honda22891]

Nothin runs like a deer, unless its being chased by a CAT
