Tow Starting Caterpillar D8 Bulldozer

Tow Starting 1952 Caterpillar D8-2U with a 1963 Caterpillar D8H-22A. The 2U had not been started in over 2 years so took a couple of attempts to get the oil around and ready to fire. Check out our website www.bostonpowercat.com for more videos, pictures, forum and blog.

This is going back 35 years, I was a mechanic, and we had cable blade, pony start dozer. We also had a old dozer that had the clutch/brake to turn. I remember changing out the driveshaft brake for the clutch several times. So long ago, I cannot remember the CAT model numbers. Was not long after that we transitioned to Hydrostatic transmissions. My favorite was a Fiat/Allis that ran a non-muffled stack right out of the turbo. Loved to smoke out my fellow wrench benders on start up, lol Thanks for the memories.

[@howdafkshdino8902]

The sound of the turbos is awesome.It sounds like inside an engine room of the old oil supply boats from the 70`s and 80`s...Thanks bostonpowercat.

[@justforever96]

Oh, I love it! Thank god for people who keep these things running. Sounds partly like a steam locomotive, and partly like a jet fighter when it fires up! And of course, I have to add that a "bulldozer" is technically just the blade attachment. The rest is actually a "caterpillar tractor". Just like how a "backhoe" actually refers to an attachment that fits to the back of a tractor. Anyway, point is, you can't call a bulldozer without a blade a "bulldozer", technically. Not that that will stop me!

[@Bostonpowercat]

Glad you enjoyed 👍👍 and yes you are totally correct in saying that it isn't a bulldozer without the blade, we put bulldozer in the title as not everyone knows what a D8 tractor is, but you have a good point 👍

A number of years ago I ran a 2U that had serial number 15501. It was bought from James City County in Virginia. It was originally a US Army COE machine. It had been adapted with a 24V starting system and the PONY removed by the CAT dealer, also had bolt on track segments. We removed the double drum winch to lighten it up a bit. To my knowledge it's still alive and walking in the Upstate area of South Carolina.

[@Bostonpowercat]

Any idea what year it was, I guess it must have been late due to the bolt on segments? Good old Cats never die, be great to see it in action :-)

[@gbh559]

+Bostonpowercat If memory serves, it was a 1951 model. It had the bolt on segment ring welded on by the CAT dealer. The electric starter motor made starting a breeze even in cold weather. I especially liked running it in winter. After a few minutes of running, you were plenty warm. In the summer, it was HELL with a set of tracks. The cooling fan wasn't reversible, made you want to ride naked because it was so hot. I always wanted to try one out with the pull scraper. I bet that was quite an orchestra to conduct. :)

[@Bostonpowercat]

Lol riding naked, now that would get a few looks on the job site!! Just done a bit of research the 2u ended in 53 at serial number 23537 so 51 sounds about right. The bolt on segments were a huge improvement, so much easier to work if they needed changing. Would love to get a pull scraper ourselves!! So you still in the industry? Cheers

Year's ago I worked for a Hard rock contractor that had an old Cat D9H Built in 1958. that had a gasoline pony motor like this one. Year's later while working for a pipeline outfit which used D9 based Pipeliners. We were in a very remote section of mountains in southern Arizona when we had one lose it's starter. They were so old that Empire Machine(Cat dealership) had no rebuilt units nor did anyone else, so I pulled it out shipping it to our shop in Farmington NM via Greyhound (It weighed 98 pounds) a few days later a second D9 lost its starter. So for the next 2 weeks I had to start 1 D9, pull it's starter, then travel to the next D9 install the starter, fire it off, pull it, travel to the next D9 and repeat.

We then drove back to get his Little leyland tractor, battery flat! We tow started that with his ute, across we go again, this tractor wouldn't do it either grass to wet and tractor to light. Back again to the shed with the leyland to get the big nuffield, you guessed it battery flat again! towed the Nuffield with the Leyland. Then back and towed the D4 with the Nuffield!. Total time taken 2 hours, time to fill the ditch 10 minutes Oh and before we started that morning we had to crash start the ute! because it had a stuffed battery too!

Do you guys just do this for fun, or is this to preserve the engines and drivetrains, so they don't just sit there and rust? Also, where does all the smoke coming from under the hood of the second D8 come from? The intake manifold, or is that just leakage from the exhaust?

[@Bostonpowercat]

Bit of both really, it is a hobby, but it does the machines a world of good to give them a run now and again, gets the oil around the engine and keeps the tracks running freely. Well spotted on the smoke from under the bonnet on the second D8, it's from the exhaust manifold, the manifold is pretty rusty and there's a few holes in it so not all the smoke is going up the stack!! It's on the list of jobs that need doing, it's just a long list that never seems to end is the problem!!

How does pulling a dozer in reverse "jump start" it? Does it work with all dozers or only a certain engine type?

[@Bostonpowercat]

Hi, are you specifically talking about starting in reverse? If so any Diesel engine that has a manual gearbox will start in reverse as long as the engine is turning over when you pull the clutch in it should start weather your going in forward or reverse. If the engine has an automatic box then you can't jump start it at all. Hope this answers your question?

[@PatrickDKing]

Bostonpowercat Hi. I mean it looked like the dozer being pulled somehow got "jump started" because of the other dozer pulling it. Kind of like how you can take a manual truck and let it coast down a hill, pop the clutch, and have it start. I just wondered if that was the same thing that was happening to the dozer being pulled.

[@Bostonpowercat]

Yep you've got it, exactly the same as if you were to coast a truck down a hill and pop it into gear to get it started, just in this case we used the other dozer to pull it along to get the momentum going!!

[@norbertsiewert3917]

Some diesel engines can be started in the wrong direction, if the gear is set in reverse, and the vehicle is pulled forward. Not good. There is no oil pressure, and the dirty exhaust exits through to air filter. Better stop it immediately!

[@RDCST]

The pedal are brakes? What about the levers? What are those two big pots at rear?

[@Bostonpowercat]

+RDCST Thanks for the questions, yes the pedal is the brake, the levers operate the steering clutches. When you brake and pull the lever at the same time it only applies the brake to one track so the machine turns left or right depending on which lever you pulled. Hope that makes sense? The two big pots on the rear is the winch, technically known as the cable control unit, the steel rope can be used to operate a compatible scraper box or it can be used to lift the dozers blade up and down when attached. Everything is hydraulic these days, but before hydraulics became prevalent the dozer blade was lifted up and down using steel rope, besides just fitting the blade a whole gantry has to be fitted so the cable can run from the rear to the front. Any other questions just let us know. Cheers 👍

[@RDCST]

Thanks for you answer, About the two big pots, in both models they look different, in one model the to big pots are front to front, in the other model they are in one side each, like to eyes. Sorry, I don't know how to explain better. Their job are the same? Because it looks like you are talking about the one that the big pots are front to front.

[@Bostonpowercat]

+RDCST Glad you got back to us with another question 👍 They are both cable control units, just different designs and yes they do the same job, but I know what you mean they do look different. The machine doing the towing has the two big pots front to front, that cable control unit (ccu) or winch would have been more common on the bigger machines, the Caterpillar D9. The two big pots front to front earned it a nickname with guys in the industry, it was called the "Mae West" winch after the actress who had two rather large assets just like the winch!!! Any other questions just let us know. Cheers 👍

A very manly video indeed!

[@Bostonpowercat]

Thanks very much, you certainly have to be prepared for some oil and grease working with these!!

[@Jean-vz8co]

Je connais tous les modèles de ces machines de 1935 à 1980...... et jusqu'au dernier boulon!!!...

[@shreddder999]

What do you do with them? The web site stated in the description/comments does not exist, btw.

[@anthonymacneil2279]

Where can I buy one of these old Dozers in Canada

[@Bostonpowercat]

+Anthony Macneil we are based in the UK so not sure where you would go in Canada, but you could try looking at www.acmoc.org and you can even post a wanted advert on their forums and see who gets back to you. Also have a look at machinery trader. Hope this helps. Cheers

What is this? A big boy toy box.

[@hlyautey]

Are they "parade ready" now?

[@Bostonpowercat]

Not yet!! Still parked where we left them after making the video! They only really need cosmetic stuff doing to them really apart from the one needs an overhaul of the pony engine so it can start on its own. Have been busy working on another project over the summer which should hopefully be ready soon.

[@hlyautey]

+Bostonpowercat I was joking, of course. I don't believe crawlers like this would be welcome in the Christmas parade.

[@Bostonpowercat]

Ahh I see!!! I didn't realise you were referring to the Christmas parade, I thought you meant a vintage machinery show where they have parades as well !!

[@romnada]

cool i didn't know that ?

[@Bostonpowercat]

Hi, what didn't you know?

[@bestamerica]

' try bulldozer D11... very big, strongest, super heavy weight... where to get 2 videos in 1 video same time

[@Bostonpowercat]

Would love a D11, but they aren't cheap!!!

[@bestamerica]

who is a word -- they --... dont ask about currency cheap or not... not important currency... D11 is the great machine

[@Bostonpowercat]

+bestamerica yes your right the D11 is a great machine.

[@bestamerica]

yea yea... thank catpower D11

[@deweys]

I wish I had a bulldozer :(

[@gruntabro1]

tried doing that once with a D9E, crash started it down a slope and the old bitch backfired and blew the oil out of the airfilter oil bath all over me haha

[@Bostonpowercat]

Lol not a good experience !!

[@Zayjug]

where does the turbine sound come from?

[@Bostonpowercat]

The turbine sound is coming from the turbocharger on the engine :-)

[@Zayjug]

Oh it isn't N/A! Didn't know about it. Cool!

[@Bostonpowercat]

No this one isn't N/A, the turbos on them are quite often referred to as the dustbin lids they are that big!! Thanks for stopping by and asking the question though 👍

[@satyaanweshi]

Great display of mechanical power, thanks, but the website www.bostonpowercat.com does not work..

[@renohuskerdu4592]

How about dozing some bulls next time? Like, put on a blade and squash some crappy little Pryus or something.
