Mack M-45SX Documentary

[@mikewhipkey6863]

It amazes me that you don't have equipment manufacturers beating down your door trying to hire you as a spokesman.. You would be pretty good you probably know more than most of their employees

[@PAmining]

The truck is currently awaiting an engine rebuilt with an uncertain future. Thanks man!

[@lancecluster]

Love these PAmining videos, neat old equipment with a ton of information and history, delivered in a straightforward way where you can tell he really cares about the subject. Wish there were a lot more of them.

[@jowenjv4463]

You speak really well. (Kind of dumb to say this, but it really amazed me how clear, regular and understandable you are)

[@petermalanchuk8210]

Thank you for the excellent video. The front axle looks to be a very popular Rockwell FU901; 28,000 Lb capacity, used on nearly all logging off highway trucks with cast spoked wheels (Hayes HDX, Pacific P12 & P16, Kenworth 850 and Peterbilt 397 off highway tractors). Clark 150,000 Lb. rear planetary axles were quite common in this class truck and tractor. I like Mack's super strong frame, looks to be an "I" beam cross section with 3/4 in. web thickness and not a "C" section. I'm impressed that Mack made their own "Plani-drive" (sp) rears. The engine is for sure a Cummins, V12 but don't know if its the older NHV or newer V1710C engine. I don't know if the V1710 C was naturally aspirated of turbocharged. This truck looks quite restorable!

[@garylantz8630]

Excellent job of documenting and explaining an important part of North American heavy vehicle history! Your information was on the money.

[@josephalexander3884]

Thank you. Fantastic video. Short, concise, extremely informative. I’m looking forward to seeing more of your work.

[@PAmining]

Your welcome, glad you enjoyed it!

[@lewiemcneely9143]

Where I used to work started out with old DM-600 concrete trucks with rock beds. Then got a couple of R-35 Eucs and an R-22. Then a RD-800 and DM-800 with rock beds, 12 speeds with 350 Dog motor and a 400 V-8 Dog. Then the got the 771 and 773 Cats and the RD-800 went to stockpiling. I drove a DM-600 with a bed about like that that came fro W. Va. It had a headgate you could camp on and a strut in the middle of the bed to keep it from spreading apart. Glad those days are over.

[@cheechchongfan97]

My grandpa used to have a red Mack DM600 that he hauled coal with. It was very rough riding but I always enjoyed when I would get to ride along on hauls with him. Thanks for the video, I'v never saw a Mack like that before. I hope she gets rebuilt so she can run again.

[@curtisforbes8650]

This guy is the professor of Mack trucks.

[@adreabrooks11]

Great video - informative, concisely presented and without a ton of drama. You let the truck and its features speak for themselves, and that's appreciated. Also, the climb into the cab made for a great visual experience.

[@joshtaylor4249]

I'd love to hear it run.

[@gangesexcavating]

I think this is one of the better videos you have done. Real good solid walkaround, with loads of pertinent information.

[@jontheoldmechanic]

Great to see all these old machines that I grew up working on

[@ScaleCarModels]

Another amazing walk around love Mack trucks especially these older ones.

[@PAmining]

Thank you! Glad you enjoyed it

[@craigsibley8161]

Great content 👍👍👍 A few Mack's made it to Scotland but were a rare sight indeed...

[@Cumminsmaniac16]

awsome!!! i always enjoy your doc vids. man that ol mack sounds tough with an ol cummins & allison. i bet "Big Red" has big balls

[@stevieg2305]

Pa mining your vids are awesome and addictive !!!!

[@PAmining]

Haha, I imagine they are. Thanks!

[@vinnysantucci1596]

Very cool. You really know your stuff!! I have that same Mack emblem, as on the front of this. I always liked the M's, because of their offset cabs, like my favorite the U model. Also love the big Mack logo on the door.

[@MrAirbiscut]

Now that is how you do a narrative on a truck, nice job, that truck is so big it needs 2 bulldog's perched up on top of the radiator

[@jamesiec61]

Very informative presentation as usual. Impressive truck, presumably still in use.

[@canvids1]

excellent walk around with the big Mack truck Justin

[@bigredc222]

Good job, very informative. Thanks

[@paulde0]

U rock, watch all your stuff.

[@zekefisher2120]

I work with a man who's worked on that truck since he started. The idiots scraped the truck before the Mack museum could get it and the joke of it is the museum would have gave them way more then what the thing went for scrap. It's a shame that the truck got scraped but already the grill and Axel's were keyed from the scrap yard. Stupid things people do to hurt the history of the mining and history of American hard work.

[@Error-5478]

This dude is amazing... I was thoroughly interested.

[@rmbarkey]

That was a great documentary! Thanks so much for putting it together. I bet that Mack is pretty loud inside the cab. It looks cool but I’d hate to drive it for an 8 hour shift every day as I would imagine you would be very tired. Thanks again!

[@PAmining]

The trolly brake is basically the same as stepping on the foot brake on the floor; only difference is that it locks down one set of tires while the brake on the floor locks down all tires

[@oscartonga2668]

Excellent video. Can't wait to see more!

[@PAmining]

"Float" is when the box is completely lowered on the back of the truck

[@joelchils]

Now that's a big Mack

[@lindro123]

would love to hear that baby go!

[@beetragg]

Cool video! what a beast, would have loved to see and hear it working.

[@PAmining]

I think we all would have. Thanks!

[@PAmining]

Absolutly, that way I know what I'm talking about. I also plan how I want to film the machine and in what order I want to talk about stuff

[@1stinenergylimitedmdevelop533]

50 tons per load. That truck has worked bloody hard

[@sammhill8686]

Great documentaries. In the early 70's, in a storage lot on the Minnesota taconite range, I saw a bunch of old, not used anymore, haul trucks. Each had 2 six cylinder diesels, 2 transmissions, and tandem rear axles, with a driveshaft from each transmission going to one of the axles, giving four wheel rear drive. The shifting levers were bolted together.Somewhere, I have a picture with me standing with one foot on the top of each engine, as the hoods were long gone.Any idea who may have built those trucks?

[@PAmining]

+Samm Hill Those sound like Euclid FFD or LLD models for sure. I've filmed both types. They were a very popular truck on the iron range back in the day.

[@michaelrhodes9178]

Great vid..

[@ToonandBBfan]

Splendid old truck but as you said it would be noisy and very hot in the cab in summer and no doubt very cold in winter!

[@danielmarshall4587]

Lovely vid, lots of info thank you.

[@elliot330]

Nice video, thanks for taking the time to put it on here. 1 question, was is "float" referred to on the tipping bed? Thanks Elliot

[@gangesexcavating]

great looking truck. What big red burly beast!

[@ckelley63]

Very informative!

[@TourettesOrc]

What a bad ass dump truck

[@JasonWaterfalls13]

Hell of a walk around vid!! Awesome job man! Love that Mack. What's her fate? Is this truck still being used or is it donzo and heading for the scrap yard? I'd love to see a working vid of it! Thanks.

[@ableone7855]

Good video!

[@barrywhite1821]

Great job bro and thanks.

[@PAmining]

No probs, glad you liked it!

[@bert26a]

I've seen in some heavy equipment magazines that Western Star is offering trucks of that size. Have you seen any of them in PA?

[@brentsmith4394]

Very good video

[@guerrillaradio9953]

Awesome. You out in Altoona, Somerset? I'm from York, PA, born and raised.

[@NickHey]

This looks like a precursor to the articulated off-road haulers

[@PAmining]

Thanks

[@arborist460]

I could see mines here in eastern ky getting alot of use from a fleet of these. id love to see one. talk about an orange blossom special...this beast would pull the frame out from under these new plastic toy trucks lol built for the work

[@scottprendergast3143]

so true...its been said that the 2 strongest trucks the WORLD HAS EVER SEEN are: MACK BULLDOG U.S. OF A. & KAMAZ of Russia

[@PAmining]

I've seen a lot of Western Star triaxles used in mining, but no off-road trucks of this size

[@bakfixx]

Amazing payload capacity.

[@sinclairopaline]

Tough just massive tough,hot dirty ,smoky,justbphukin love it.

[@jasonthompson8668]

I like that dump truck it is cool I wish you could have started it up I wonder if it still goes to work I like this video

[@PAmining]

Thank you!

[@PAmining]

Thanks. Oh I'm sure she does!

[@Heavytruckphotos]

Awesome!

[@scottprendergast2680]

Detroit or cummins-? In the great arctic convoy if '56 MACK BULLDOGS WENT TO THE EXTREME MAGNETIC 🧲 NORTH POLE- their bulldogs produced 600hp and PATENTED FAMOUS MACK BULLDOG 4wd BOGIES- So my question is - with a royal pedigree going back to Gus Mack of the mack brothers, brooklyn NYC IN THE 1890's, when they built horse drawn teamster wagons- then a bit later on -buses- yes many are totally unaware that the first MACK TRUCK was in essence.... a bus- it worked prospect park in brooklyn, around 1903-06, and was called the "MANHATTAN" It was a large flat affair with wheels of course and 20 or so seats for the passengers- one up front for the operator. Interestingly enough, Mack didn't have a bulldog on the hood until '32 on..when chief engineer by the name of MASURY while in hospital for appendix surgery, in spare time, carved the bulldog out of wood - of which an exact mold was taken for the famous "mack" bulldog, that you see today- look close and see he has his own little pat. Pend. No.on the front of his thick collar- yes, look sometime- preferably not when the Growling BULLDog is on the move though! Before the '32 design of the chrome bulldog in the hood where the motometer once was- there was a metal plate which had a bulldog crazily ripping up account sheets (bills) with the caption "CUT COSTS WITH MACK"( usually on the early ab and ac models- which were built up to the ak years)when the bulldog hood ornament was adopted - after the 1932 ak models) the motto of the company then changed to: "PERFORMANCE COUNTS" I know not as much as This gentleman and really not that much about Mack Trucks but Insure do love them

[@jw4620]

What a beauty!

[@barrywhitley2535]

Excellent video and a great truck. One question: Say the truck has been standing a long time and loses all air pressure, how would you start it?

[@georei]

Air compressor big enough to turn the starter

[@jimsonbrown9768]

Doesn't have to be a big air compressor. Just pump the tanks up to 120 psi or so.

[@jamminwrenches860]

He said it had a 25 horse pony motor. It's probably a little 3 cylinder diesel that can start from a normal car battery. So if she has been sitting then use jumper cables or throw in a new battery (say from the pickuptruck you drove there in) fire up the little motor and wait for it to build air pressure. Or use a portable compressor or a semi trucks air compressor to build up the pressure needed. I would love to try

[@justinmartin8887]

Most guys park air starter trucks near shops in case that happens, they just charge the air system with shop air

[@librandancer]

Nice video.

[@JHaggis]

That is some bad ass truck! Ready go some horror movie i think. What paper hang on steers? Awsome video again.

[@elliot330]

Thank you..

[@GearHead1625]

how does the trolly brake work?

[@victorbart]

Cool video! thanx for making it. I have on my channel footage of a m45sx from mammoet.

[@kaydanandthebestfamilyinth4688]

Cool

[@13frontrow]

good video buddy what would the top speed of this & the klien hauler be..

[@PAmining]

Thanks. In the range of 40+ mph

[@lewiemcneely9143]

the RD and DM-800's was 35. We had to road them for service before the shop was built at the boulder hole.

[@PAmining]

Your welcome!

[@UnitCrane514]

Which Cummins engine is installed in this truck? I know thats not a 12v-71 Detroit! Is it out of order? I see its been red tagged! Air start is way better than electric in some ways!

[@ModelingSteelinHO]

Now this is a truck ! Any chance of getting video of it in operation ? Bet she purr's.

[@jed-henrywitkowski6470]

I think there is a dump bed from one at the FMRX yard in my town.

[@Mariusdubose]

I watch alot of your videos and I have to ask....Do you visit the equipment before you video them and do research or is this personal knowledge?

[@dougbruce4978]

comming from southeast ky i can rember them as well as the r models

[@cuzinitr]

Great video! Count me as a new subscriber.

[@TJV83]

We call them Mountain Macks here in northern Kentucky and southern Indiana

[@1988diesel]

The engine in the truck in this video looks like a Cummins V-12.

[@suzanne19720000]

Just wish I could have heard the air start otherwise great video

[@johnnysmith6028]

What size wheels and tires? And tire ply capacity

[@8068]

Is the truck still in service or has it been scrapped?

[@PAmining]

This truck was scrapped a couple years after I filmed it

[@Justinofalltrades1]

wow very interesting, my great uncle used to be president of Mack truck in Tennessee. pual cannon i think his name was if i'm not confusing him with one of his brothers. he sadly just passed away although i didn't really know him. he was 88

[@SuperAgentman007]

1:00 how come Mack did not use their own engines? :-]

[@fordnut4914]

that is the year I was born.

[@Natethanastysnake666]

Start er up!!

[@franktechmaniac7488]

246 trucks were built in total? Doesn't sound too successful. Were they too expensive or what was the problem?

[@PAmining]

Thanks. Actually she's out of service for an engine rebuild.

[@MadaraUchiha55910]

It’s strange this truck being a Mack that it doesn’t have a Mack powerplant

[@paulpochan9631]

.. I have the "Tonka" version of this truck...!!!

[@brandonhersey197]

cummins power

[@crushed1126]

Looks like Mack used a Euclid cab and fuel tank on it.

[@bradleyogden5688]

Sure looks similar to a Pacific, except the dump bed.

[@nilamor2830]

Realmente perfecto

[@gregorysampson8759]

OPEC on wheels

[@ericlakota6512]

They take thease big boys if they can find them and take the dump off for a masive heavy hauler truck halamore in rodisland has one you can see on utube its a beauty all fixed up with a fifth wheel

[@donaldbartram6315]

A real quarry truck. not come Yamahachi BS

[@stephenhansen8906]

Mack sold out a quite a few years back

[@jamielacourse7578]

no bulldog on the hood on these trucks?

[@AlarakTheHighLord]

I thought it would be 6x6

[@JohnDoe-pf2ps]

C'mon man don't tease us by not turning that monster on
