Detroit Diesel 2-71 Powered Dozer. Allis Chalmers HD-5 2 stroke diesel

[@danielseelye6005]

Starts on the button One oil leak No crazy smoke Brakes are free Cleats are not missing Hydros work (and don't leak) Blade isn't tore up or gouged out Can shift into fast travel Treads are not sagging Bogies are working (and not missing) Made it up Dyno Hill in one shot Other than deferred maintenance, cosmetics and the winch, she's got better than great bones to start with. Fantastic find, Scott.

[@lesgaal4017]

Apart from oil leak from a visual on your video it looks like a great bye , maybe upgrade the roll over canopy with something will withstand a tree or roll over for operator safety cheers.

[@tomhamilton9816]

Awesome new toy, I love ❤it!!!Pretty impressive temporary fix on that oil leak! Also, running the rack should be super easy on this one!! :)

[@londolly]

oil leak rear of engine , cant you read ?

[@prodkey]

A gentle reminder: remember to put it in neutral and pull back / set the hand clutch when idling and or parking. Other wise your throw out bearing is always running. Great purchase! Should help pull a bus up the hill!

[@riccardo3212]

It depends, some clutches on dozers have 2 stages, so you can keep the clutch on without destroying the bearing. This is possible only with specific push plates systems.

[@kg4muc]

This would be a great driveway fixer after the flood up here 😊

[@Hat9757]

Back in the day, my dad had several A-C HD 5 dozers and loaders. Those 2-71 Detroits are hard working engines. I’ve crawled up under a many to get the belly plate off to change the oil.

[@YouScroob]

I've had a 1955 HD6 with a 3-71 for about 27 years. I got screwed when I bought it. It was always a logging machine here in Oregon, with ROPS, rock guards, sweeps, Carco winch and a straight blade with tilt. The previous owner told me he had backed into a stump and tore out HS reverse, But he actually tore it up so bad that the ring and pinion were broken. So, I've replaced the tranny, ring and pinion, added some plates and frictions to the steering clutches. That was a nightmare of a job. He had the tracks packed with mud, so I could not see how bad the undercarrage was. I replaced a few rolls and the track rails. The machine originally had the AC 4 cyl. diesel but that got changed to the Detroit. ( That was the "hot setup" in the old days) Looking at your machine, it appears that it was originally a farm machine, and later the blade and a non stock hard nose was added. I've put about 700 hours on it , mostly building road in rocky, hilly ground, only needing to replace the main clutch a few years ago. If you run into any snags when working on your machine, contact me. I'll gladly tell you what I know about working on these old things.

[@throttlebottle5906]

di you expect otherwise from a "logging machine", they always run everything into the ground and give it full on abuse.

[@marty0715yt]

Oh Hell Yes!!!!!!!!!!!!!!!!!! Pulling bus's up that hill just got easier.

[@BusGreaseMonkey]

It will be fun!

[@railroadenthusiast6246]

Just fix the winch up and it will pull them up with ease. Or tow them

[@railroadenthusiast6246]

​@@BusGreaseMonkeydefinitely will be something great and different to see on that hill.

[@Qrail]

My head was spinning in the start of the video. A “cat” with a Jimmy? Did not compute. Now I get it. You will have hours of fun with that, and it will probably outlive you.

[@michaelholden5131]

Great find, we will get a lot of entertainment with the fixing and operating of this old dozer. You guys are killing this youtube stuff.

[@bigrockauto]

Great buy track gears look good, steering clutches work, small enough to trailer. 2-71 Detroit diesel. You win!!!

[@ChuckNorriz1122]

Needs new grouser pads, sprockets look shot and I’m sure the chain isn’t in great shape. I’d still buy that in a heartbeat! What a fun project.

[@djcommie]

Marty T would approve of the content and quality!

[@normmcrae1140]

OK, Scott - You're READING MY MIND!!!!! I was thinking of how a bulldozer would have made it SO much easier to pull that last bus up the hill - when the tractor started to slip.... And NOW you've DONE IT. It should make maintaining the road MUCH easier, too!

[@notajp]

Biggest thing to pay attention to on any old dozer is the undercarriage. Repairs there can run into thousands if there is a lot of wear to track pins and bushings, drive sprockets, or the rollers.

[@gullreefclub]

From what I can see the undercarriage is worn out. The track pads are worn thin, the sprokets are worn and I can’t believe that the chains are any better

[@jazzandbluesculturalherita2547]

WAY KEWEL OLD DOZER! Love to see it after you've got it painted out.

[@TimsWorkshopTJY]

Cool, can't wait to watch this one later. Deisel Creek at the old bus barn. Love it

[@clockbuilderhg]

Oh man, that thing is cute! I'm glad you saved it!

[@mevinson]

Scott your "Old Alice and Chains" dozer is a gem. You can probably fix that winch with some hard nickel welding providing all the pieces are there, we fixed ours , the gears are cast steel not cast iron so welding is an option. Those old winches are terrific!

[@kylemartin2594]

Get the winch working. Real asset..

[@Sherlock067]

Those AC dozers were built good , this one still ready to work! Great purchase Scott!

[@RJ1999x]

Allis Chalmers 👍

[@louk231]

That tractor got very lucky being bought by Scott...

[@GNX157]

This will make a great addition to the compound. So many possibilities.

[@parker1ray]

I had a driveway from hell just like yours when I live in Knoxville! When I built my new home just north of Chattanooga, I had the home placed 35' off the front property line and my drive is 20' long! Thank goodness. I also had a small dozer blade on my tractor and used to have to fix the gravel drive three or four times a year after heavy rains!

[@richardhughes9074]

Great addition that will be a fantastic work horse for you ! No more fixing dead buses at the bottom of the hill !

[@youdandee1]

That Detroit Diesel is right up your alley for sure I operated a HD 25 allis charmers for a while in the 80s

[@RJ1999x]

If it was an Allis Chalmers it was a HD21

[@steamfan7147]

Sweet little machine, those 2-71's are bulletproof little engines. I have a 2-71 genset off an old RR refer car, it's rated at 25 KW continuous power, but still sips fuel.

[@xr7coug]

Nice find, its a perfect size for a home owner with a "big" yard

[@DontCryAboutIt]

The engine is the least of your worries when buying vintage heavy equipment

[@maxvanrunkle1052]

That wonderful dozer just got very lucky to have found such a good home!! Congrats!! Love it!! Looking forward to seeing you guys fix it up!!

[@Friedbrain11]

I remember seeing one of these when I was young. Farmer thought the guy couldn't do what he needed to do with a small dozer, but that guy knew what he and his dozer could do and he got it done! That is the little dozer that can get it done:)

[@dennisreeves632]

What cool little machine. That should pull a bus up the hill!

[@buddyweiz]

Also John @ farmcraft101!

[@quiet_desperation]

Good job you know someone that knows their way around a 71 series Detroit diesel 😊

[@pdxRetired]

That dozer will help keep your road nice!

[@PepperKingsley]

May granddad had one just like this in rural Alberta, I believe it was an AC, it always started and could put in a full days work!

[@carlthor91]

Scott, I don't know if anyone has mentioned, but, ITR America, does have a LOT of track/pads/rollers etc., for most equipment. Best wishes from the far North.

[@bobjohnson4025]

I have basically the same AC dozer... a 1956 Hd6B, 344 ci. diesel 4 cylinder and winch. Only have had to do clutches and brake bands in the last 35 years I've had it. They are good strong dozers. Good Under carriage parts are extremely tough to find these days.

[@elrobo3568]

That looks like an old fire line cutting unit. the blade is like we used in wild land fires. I think you got a sweet unit!

[@dont-want-no-wrench]

now that is what you need around there.

[@BusGreaseMonkey]

Can’t wait to get a nice weekend to play on it!

[@rudycarlson8245]

@@BusGreaseMonkey do you think the oil leak would be easy to fix?

[@dennisgardiner43]

Very cute old school tractor. One of the smallest HD tractor made back then. Have a JD myself, the engine was a diesel originally, JD made a gas version of it, that is a beast.

If you play back the dozer plowing sequences at double speed it looks like a new machine!

[@russellwood5867]

Scott the scecret to long life on those old dozers is gease grease and more grease.

[@carlwilliams1570]

Nice old dozer! I usually pull the pin on the break away switch to lock the trailer brakes if the trailer has a good battery. It keeps the trailer from rocking and banging the trucks parking gear.

[@railroadenthusiast6246]

I absolutely love old school bulldozers like that one. I'm going to name it ( old timer de) the de standing for Detroit. I think it's a good name for it. Hope to see more videos of it and the engine rebuild project on it. Weather it's a bus, or construction equipment with a diesel engine you sure know how to fix them up to great running condition I've learned alot from your channel.

[@lilreb601]

Awww yeah! I can WAIT for more videos on repairs on this! I love, LOVE old dozers and BGM!

[@gtr1952]

It looks like someone has given it some attention. New(er) hoses, bits and bobs. We bought an old Cat. It was in the early/mid 80's and I don't remember too many details. Being a lump of rust that ran was one! Another was replacing the pony motor by machining holes in the bell housing! I don't remember the starter details, but it replaced the pony motor, and we got really lucky with the starter hitting the ring gear just right!! 6 sets of eyes and a lot of luck!! LOL But it worked!! Lot of fun too! 8) --gary

[@gewing61]

Great find Scott. Looking forward to upcoming videos

[@NathanPellham-yo8pl]

I love my hd5b with the 3-71 Detroit Conversion loads of power with it, if you hook onto something that doesn't want to move the drum with that 3-71 running at 1/2 to 3/4 throttle will have the nose of the cat looking up at the sky as your draged backwards, I also rebuild the spring pack and added an extra main leaf that goes into the factory saddle, there about 1/8 inch thicker then the factory main is and added 2 extra clamps one to each side to help keep the spring pack together better, broke the original ones shoveing out cherry trees root and all in an orchard of my ol neighbors.

[@bartfranklin1358]

The operator is pretty good! Grading with a dozer is pretty tough until you get the hang of it. Your butt is your guide to cutting a good grade. May need to replace the track shoes (plates) as those are pretty worn. Thanks for sharing!

Well it won’t set any land speed records, that little dozer is going to be an invaluable tool for you folks. Nice score!

Hi, new subscriber from Australia, started watching this vlog on the dozer as always looking for guys who love saving old iron and then saw the bus thing and thought well if he wants to save a dozer then maybe I could look at his bus vlogs to and so far watched a couple and really enjoying the new content. Can’t wait to see you sort the issues out on this dozer and catch up on the back log of your posts. Well done
