Hobbiest ownership of such a beast requires a very serious commitment. Just moving it from one venue to another is a serious logistical puzzle. Hats off to the people who bring them for us to oggle.
Dad and I had a call from our local scrapyard telling us it’s one of these was delivered. We ended up picking it up and it was worn flat out but we were able to get about 1000 hours out of it before it was just dead. It did push like a beast.
I drove one of these for a couple months pushing pans in a kaolin mine here in middle Ga. many years ago. It had straight pipes and a spring loaded blade. She was a monster. When I first started my timing was off and when the pans would stop I hit them so hard it sounded like a train wreck Lol... I got used to it after a short while and the pan operators sure were glad. I think some of those guys still suffer from whiplash. The company I worked for at the time was contracted to remove overburden. They had two of those machines. God that was a lifetime ago...
In 1972 or 3, Dravo Corp moved a fleet of equipment to Meadow Creek Co. They built a dam at an area known as Western Box. The dam site is @ 1100 feet above sea level. They had a brand new HD 41 on that job. It was brought to Fraser Co on a Rio Grand train assembled, then moved several miles to the dam site. We thought it was the coolest thing ever.
Northern improvement in north dakota had 4 and sometimes 5 of these HD 41 pulling a plow for putting in pipes for rural water in the 80s and 90s . I followed them for miles while I worked for an engineering company supervising putting in the systems
Thanks for posting. These were built in Springfield, Illinois. I did the prior to guards and final inspections on the 41's. Standard track length 32 inches. ROPS canopy was special equipment until OSHA. Then ROPS canopy, seat belt, back-up alarm, and horn were made standard equipment on January 1,1977. Note hydraulic oil cooling radiator in front of fuel tank with a deflector to keep hot air off operator. Fiat got control on January 1,1974. In 1976 and 1977 were record sales and by 1985 they closed the doors.
I remember the IT hauling these to East Belt yard in Springfield where I grew up. Chances are, I was standing next to the track when this was going by me just south of Cook st. I was 10 years old.
The hydraulic cylinder on the left side of the blade is for side to side tilting. I hope whoever owns it would take some time to replace or tighten all of the loose track pad bolts. It also looks like the sprocket segments are pretty worn. All in all a pretty awesome machine. It's great to see people showing off their old iron thanks for the walk around.
D10 ish size machine, when the biggest Cat was a d9h. I worked on our U.S.C.G. polar class ice breakers that have shafting and controllable pitch propeller systems made by Allis. They were a super power in the day. Those shafts are hollow and weigh 1 ton per foot, the long (wing) shafts being 90' long, centerline is around 70'. Built in early 70's here in Seattle back when we did stuff, anyhow, cheers bud!
Worked at Cummins Ontario in the 70s. It is a V1710, sort of like 2 NT-855 engines together. The pistons had tephlon inserts on both sides and they were 2 cylinder heads on each side instead of the 3 heads 855 had. They were incredibly reliable engines and had very few problems and generally lasted until they were worn right out.
Cool my grandpa said he got a lot of overtime doing welding on those. He got to drive some of them around to get painted as well said that was a unique machine to run.
Great walk around video. I am surprised how clean the exhaust was from the Cummins. Must be in good condition. I was working in my shop doing a refresh on a my first tractor restoration (1978), a McCormick Deering WD-40. I always use new lock washers when I reassemble. They were bright and shiny, I had the thought that Squatch would not approve. I also have been known to reuse lock tabs.....love your channel!
My dad ran a hd11 I believe back in the 70s for the power company dragging H structures across the fields after a ice storm took em down high voltage power out of Toledo Ohio He thought that was big
In 1976 the 400 hp model 31 was introduced which really killed the 41 sales. About 1980, 41 serial numbers were skipped to give the impression that more were sold than actually were. An old inspector told me that skipping serial numbers was common practice by Allis Chalmers over the years on other dozer models too. I worked for AC / FA from 1970 to 1983.
Monstrous machine in there day, hey I Hate to be that guy that seems like a know it all commenting but….. the hydraulic cylinder on the left side mounted to the push arm is for blade tilt not pitch
Like the tandem push. I would have thought that the the pusher would have a "normal blade" instead of being a pusher only. Maybe it did and I did not recognize it.
Just asking. I thought 1970 was the year OSHA started requiring roll over protection. For sure i was in Jr. High when that was required because us farm kids were opposed to roll over protection on tractors, and skid steers. We never needed it before ? Tusen Takk.
This HD-41 is more like a D10, in the “triple push” clip near the end of the video the tail end unit is a D9 and it’s noticeably smaller than the HD-41 👍
@@squatch253 This was the largest Dozer built and prompted Caterpillar to design the D10 which overtook Fiat-Allis as the largest dozer at 77 tons@700 hp in 1976, until then dual D9's (DD9) were the norm to push load large motor scrapers
Gotta love the old school engineering mentality…. This thing needs to weigh 100000 pounds to push what we want it to so let’s just make every part heavy vs make parts light and bolt a bunch of weights on it
The biggest bulldozer in the world when it was released. I couldn't imagine the cost involved with owning one, I wouldn't to be able to afford to change the fluids let alone the fuel to run it. From what I have heard there aren't a lot left in good order as most were worked hard in quarries and run until worn out.
I’ve got a few old Cat skinner friends that already had a couple decades’ seat time by the time I was born, and the ones that ever ran A-C’s for any amount of time all say they built machines that would run right along with the Cats and some would even out-perform them.
@@squatch253 I have a WD45 diesel that will fight like the devil to try and pull a 9 shank all purpose plow through red clay. If it wasn't from an overheating problem, I'd use her more. But she came from a tractor puller and was abused pretty good. And that 6 cylinder Buda sounds amazing too.
Conduit & Foundation Corp. owned two of them. Their equipment manager Joe Fitzpatric (Joe Fitz) described them as having all the grace and agility of a "three legged hipo" he was not a fan...
I’m not sure where they picked it up from, but it’s been living on the show grounds for quite a few years now. About all it does now is push some dirt for a few days every few years, and hibernates inside a huge shed for the rest of the year 👍
Because typically with equipment that is owned by a show organization, if it runs and moves for 4 hours one weekend a year that’s as good as it has to be, as there are far too many pieces of equipment and far too few volunteers to keep everything in perfect condition. It sounds negative, but that’s the reality with this equipment 👍
👍 Continental railroad was already built 🤣 , Erie Bucyus get the credit for the Panama Canal leaves me to wonder how many mountain tops it tore off strip mining 😲🤷♂️ just reckless speculation!!! ✌️🤙
I actually steered clear of the 150 for the most part, because they have their own channel and social media feeds plus a lot of other people have already made videos of it 👍
@squatch253 understandable. I've watched his video about building it, machining the parts, casting everything. When your family owns a foundry making parts is easy. Lol. It's a beast of a machine.
During the HD-41’s production run, no other manufacturer came close to it for size, weight, or horsepower. The closest thing Caterpillar had at the time was the D9, but it was a lot smaller (in the clip I recorded here of the “triple push” near the end of this video, the tail-end unit is a D9 for comparison). It wasn’t until the development of Cat’s D10 in 1978 that the HD-41 was dethroned, with the D10 weighing 50,000 lb more and having 150 additional horsepower 👍

I think it’s kept at the showgrounds year round..? I’ve always seen it at this show
Yes, it’s lived on the show grounds in a giant shed for quite a few years now 👍
Well, the engine is almost exactly the same size as the Rolls Royce Merlin in a P 51. I wonder which would cost more to own? LOL

As Tim Allen would say "More Power". Awesome piece of equipment. Able to move mountains.

What a weapon of a machine.
Big old girl! The V12 Cummins was pretty quiet especially for its size!
It's not doing anything, it was simply a demo
Awesome video so much power could not keep traction .
Excellent video that is a really massive crawler meant to do a lot of work
Allis Chalmers and Cummins, what more could be asked for lol
@kylechrist that is true i put a 4bt Cummins in my Allis Chamlers 706 B forklift it's a excellent combination
great video! getting parts for any Allis dozer is now very difficult
Beast in yellow. Trackzilla!
The one cylinder on the blade makes it tilt side to side, not a pitch adjustment.
Agreed.
Thanks for the walk around Toby! That thing is massive
That is a truly amazing piece of equipment, thank you for sharing!
A masterpiece of beauty and brawn.
It makes your D2s look like toys!!!
Love that heavy iron!
Thank you Toby ,for a look see on a great old dozer
Appreciate the walkaround. 👍👍👍
My dad ran a hd11 I believe back in the 70s for the power company dragging H structures across the fields after a ice storm took em down high voltage power out of Toledo Ohio He thought that was big
Thanks Squatch
A machine that size is one hell of a commitment for someone to undertake
Very glad people do though 👍
I was there when they had a D2 parked on the canopy. That really makes the Cat look small and the AC look BIG.
THAT VIDEO HIT ON ALL 8 ! Thanks Toby these last few videos are very cool!
What a beast that dozer is, thank you for the video Squatch.
Thanks for the video, Toby. That is one massive machine.
That is a beast of a machine!
thanks for the tour!
I have a new power shift transmission, new steering clutches, new actuators, PM kits, and final drive if you need parts
At 4:20 that cylinder is for blade tilt and if you want to change the pitch you can use the manual adjustments on the other side.
Love them trackers.🤗
Looks like that Cummins V-8 is a "hot-vee" design. Great video, thanks for sharing!
V-12
@@jimanderson1355 I was also referring to the placement of the exhaust manifolds.
This thing looks almost like the killdozer from the movie. Im sure this thing was hell of expensive when it was new. Love the Cummins diesel sound.

425 horsepower 1150 c.i. inline 6 cyl. cummins KTA
Like that big dozer
There is one of those in Adam's Run S. C. that I have been on it is a giant
Wow what a monster!
It would be fun to see a D2 parked in front of the blade on the behemoth.
The AC monster is big.
Now it would interesting to get the D2 the HD 41 and compare to the D11.
The work to be done requires the right sized pusher.
Basically the Cummins equivalent of a 3412. Like 2 855's together, just like the 3412 was akin to to 3406's.
I got a feeling you can find some spare parts for that stuck in an old Navy Sea Bee warehouse. Those guys LOVE big earthmoving gear!
I have a new transmission, final, steering clutches PM kits for the 41

Good video
I couldn’t afford to change the oil in that thing ! lol
The only difference between the 41 and31 is the engine and length of tracks the 31 uses the cummins kt1150
I think they would push about 36 cubic yards of material

That's a mouth full of dirt for the Chalmers! Must be somewhere between 6 and 10 tons of dirt on those pushes.
