The U model was made for mostly city deliveries with a lot of backing and the very short nose to meet the length limits of the day. I drove one in 84 in upstate N Y with the artic cold weather package with shutters and the thermostat controlled fan but with the 300plus with a 10 speed road ranger. Man did it pull
Thomas Ancas the u model was designed to meet the bridge weight limits of the day. The fact that it was short for city driving was a secondary benefit.
Back before STAA the trucks were measured bumper to bumper 55' in some states 60' in others. So 144" wb tandems with 90" short nose Conventionals and single bunk Cabovers Were the standard. So with a 45 ft trailer You only had 10 ft for truck. And gross weight was only 73,280 lbs. In ALLOT of the states. The federal bridge law didn't come into play till mid 80s early 90s with the 48' and 53' trailers.
U models make great spotting trucks. Sitting on the far left side plus its so easy to jump in and out of. We used them and DM's for spot tractors on offroad logging jobs. We called them sidewinders!
Amigo veo que tienes algunos vehículos mack, y se ven impecables y bien restaurados, te felicito, fuiste transportista , trabajaste con esos semi_ tractoras. Mi familia trabajó en ese año 1972, con buses Ford 600, Ford 750, y Ford 350. Saludos desde Ecuador.
Im sorry for your dad passing. Im only 12, my grandfather and I are restoring mine. Ive been into Macks since I was little. Hope you get a U someday!!!
Not as of yet. I would love to restore one like my father drove for 20 years. He passed away January of last year and I just had great memories of going with him in that truck. Some day I hope to get the chance (and funds). Still keep up the good work!
Believe it or not, in 2021 you can still order parts for these through any certified Mack dealer. My company has several that are still in service and we rebuild them from the ground up until they flat can't be rebuilt anymore. Absolute workhorses. Same for the old RD models.
wow nice truck ! i like the 2 tone colors you have there, i drove the same exact 10 wheeler, for 6 years- on a 24 foot flat bed straight job. also had the mack engine and trans with the 5 speed.
Verrrrry Coooool! What I love about those old Mack U and R models of that vintage, is that you could hook that baby of yours to a flatbed, dump, drop deck, or lowboy today and go make money with it today in 2014! In fact, I see some of these old trucks in the northeast still on the road doing just that daily. Love the garage full of Macks at the end of the video you're a lucky guy. Wish I had the cash and time I''d get a U, R, F, Cruiseliner, and Superliner!
Awesome Eric!!! Cool to hear what you sound like. Reminds me of my U, starts the same, RiDeS tHe SaMe, and even sounds the same. Nothin sounds better then our old Maxidynes!!
Love the U model! Can you show the view from the driver’s side...straight out? It’s the same as driving a cabover do to the cab being moved over. They are sharp trucks but I’ve never had the pleasure of driving one.🤩
The DM is a Heavy Duty and the U was regular. The DM was for concrete mixers and off road kind of stuff where the U was more of a over the road trailer pulling, or local delivery type truck
I still want to know if he wants to sell it. I could put it to work tomorrow for the right price and pull a 53’ trailer and still be legal in Va on Rt 15
Cobb Knobbler Technically I am right. That is how the Dm and U models are built. I was being a smart ass. Anyone with half a brain can do a very quick internet search for their question. Thank you for the reply captain jerk off.
Better visibility. When backing. Backs up like a cabover. So your looking down the side of the dump box. Instead of out and to the side. Passenger seat is not very useful for leg room tho.
@@jerrykinnin7941 were used by a few LTL freight companies for local delivery, made backing a box trailer easier as well going into a dock was very helpful
Yes it was kind of a standard engine Mack built, was rated at 315 horsepower, and was intended to be used with a 9,10, or 13 speed transmission I guess you could have got one with a Mack 12 speed as well.
If I remember correctly the 673 was the 237 horsepower and the 676 was the 283, and 285 horsepower engine. The difference was at 1800 RPM it was rated at 285 horsepower At 2100 RPM it was rated at 283 horsepower Sounds strange but kind of neat having 2 horsepower ratings on the same engine
Because the hood is so short, the back of the engine protrudes into the cab. They made the cab offset so the doghouse didn't take up the driver's side footwell.
They were intended for city delivery, when backing an old 96 inch wide trailer you could see the end of the trailer more easily than with an R model With the 102 wide trailers a little more difficult but still better than an R model
The U model was a good tractor but mechanic hated it.hard truck too work big motor the 300 was easy for the R model not the U.filters the heads mechanics cursed the trucks out.some never had AC or power steering.that off set car brings back memories.

@@jerrykinnin7941 Thanks Jerry
One of my favorite Macks, the U-model! Great video!
Back when trucks sounded like trucks
Thanks for that. I wish I still had mine.
Very rare to see one of those without a body on them. That is a sweet truck, I hope you still got her.
Awesome truck! I'm glad to see someone else appreciate the old U models!
Wonderful condition; I would love to see more of the B model Mack too
Esta ermoso ese camion max atte nicaragua

That's a tough as truck the thing about these old Mack trucks is it looks like the lights are frowning at you shit is so awesome

I love them 5-speed Mack Transmissions

...And the nicest part...no EGR, DEF or any power-robbing emissions crap. Just pure diesel!
Yep!! and you don't need a computer tech to service it! just a good set of hand tools and some air tools and you can do it yourself!
What made me pay attention to THESE u model Mack's is the strange offset cab and the how the headlights look
Now that was a truck. Damn shame they don't make them like that any more.👍👍💪⭐⭐
Because they are junk
STRONG RELIABLE TRUCK
saludos desde colombia aquí hay muchos mack, excelentes camiones
Mack Attack!😎👍
Custom built for Swan Oil Company , too cool
3:13 of course we want to see more!
I drove one, it was a tough truck air clutch and a 5spd+ hi low aux.
Love those old Macks
I remember this truck in a magazine.
that mack 611 one axles nice project that truck is maybe fast i like
Ya cool, I like how you say, "we'll play with those trucks another time"
I DROVE MANY MACKS @ THE U MODEL ALSO FOR OSBORNE TRUCKING 👍
Beautiful Plain Jane, She is a Winner All Day Long... Thanks for sharing
BOB REIMER drove and loved Mack trucks. He wrote THE B MODEL MACK SONG by
THE COUNTRY TIGERS CANADA. Drive safe.
Great Trucks. The camal back suspension road ruff but it was Awesome 👌
I drove that truck in the 80s steel everything in the cab lots of rattles.
That’s a real truck not like the plastic junk they make today
That is one awesome truck.
Good looking ford ranger
Great Bulldog ! Greetings from south Germany
Very nice truck
Used to haul iron out of US Steel Homestead works with one of these
William Thieshen you’re going way back
You got a bad ass ride donnnnt let your sell it.wouldnt be right keep it in the family
they were great in the city...
Awesome Eric!!! Cool to hear what you sound like. Reminds me of my U, starts the same, RiDeS tHe SaMe, and even sounds the same. Nothin sounds better then our old Maxidynes!!
Nice trucks!!
Great , very nice condition....
Only drove a couple U models but drove many miles in DM's It was a strange truck to get use to.. keep running the right side up on curbs,, loL
I heard MOSKOWITZ mentioned,, that's one I haven't heard in awhile..
OK. I will be waiting, I'll have to get a driving vid this weekend when I go to Nana and Papas.
Rubber duck Truck! Cool
Nice restoration, only I never liked the sidewinder cabs. Prefer the centered cab R model or superliner.
SteamGent Well hurray for you
Love the U model! Can you show the view from the driver’s side...straight out? It’s the same as driving a cabover do to the cab being moved over. They are sharp trucks but I’ve never had the pleasure of driving one.🤩
No problem sir! Love it! Some day hope to be the owner of an 83-84 (funds willing).LOL
Nice ol dog bro
You got anymore videos of that truck? Nice Truck 2 Man
had the exact same truck with a 15 cubic yd dump body - made a lot of $ 28th that baby in the 80's....
wow trucks in great shape, i drove same truck for 10 years, workhorse for sure.was it restored ?
I love the visabilty of the DM and U models. I driven several different DMs, whats the difference between
the DM and a U?
The DM is a Heavy Duty and the U was regular. The DM was for concrete mixers and off road kind of stuff where the U was more of a over the road trailer pulling, or local delivery type truck
Wowwww really beautiful mack..
Sweet looking truck. What's the difference between a u and a dm model? I own a 1984 dm685s dump truck and the cab looks identical to this one
The DM is the heavy-duty version of the U. It was made for more rigorous applications.
These where even wierder looking then cabovers how did they drive these things
would like to see the engine compartment.
I still want to know if he wants to sell it. I could put it to work tomorrow for the right price and pull a 53’ trailer and still be legal in Va on Rt 15
IO IN LIBIA HO AVUTO LA FORTUNA DI REVISIONARE POMPE D'INIEZIONE DEL MACK MODIFICANDOLEBX MANCANZA DI SPARE PARTS
You from Mass bud?
hey man could you do an update of the truck ?!
Good looker
I see it says "not for hire" on both doors.
1988diesel That's what Swift Trucks should say on the Doors
Why is the cab offset?
That is how the DM and U models are.

Why is the cab offset I've forgotten
For a local delivery type truck, with the cab offset it was easier to see the rear of the trailer than with an R model made backing easier
The r model could be a pain in the ass with those big fenders backing into a tight space the u had better visibility drove them both

300 + ?

@@bertgrau9246 I learned in a 74’ DM800 300 plus and 15 spd tri plex, #55,000 bogies, she was a beast
237?
If I remember correctly the 673 was the 237 horsepower and the 676 was the 283, and 285 horsepower engine. The difference was at 1800 RPM it was rated at 285 horsepower At 2100 RPM it was rated at 283 horsepower

Can anybody tell me the advantage of those offset cabins?
Because the hood is so short, the back of the engine protrudes into the cab. They made the cab offset so the doghouse didn't take up the driver's side footwell.

Do they make r models with that pug nose?
no
Fala o valor
That's definitely not a 72 cab

Do you have a U model? Check out my channel and videos, my U models on there. They are my favorite.
