I've been in the driving game for nearly thirty years and have had the "pleasure " of shunting around Australia with a B model mack and the idiosyncrasies of its twin shifters, in Oz we get the oxy-acetylene torch out and heat the shaft of the shifters so they can (with considerable practice) and the usual amount of common sense and skill be moved with a single hand and a lot less drama.
manufacturers usually frown on this practice, not sure about the transport authorities
I started out on a old B51 Mack with a duplex back many years ago hauling produce out of FL. Hardest thing I ever tried to learn. I never got to the triplex. I talked the company into putting me in a Freightshaker with a Fuller 10 speed Roadranger.
T his guy is GOOD , only time he used the clutch was to take off from a dead stop ! Is one stick a high range / low range & the other a 5spd main stick ?
nice truck, I've got a ford with the same setup. no matter what kind of condition your in there's a gear for it with these 5 and 4's. next video show em how to shift both boxes at the same time.
This tri plex Mack brings back a lot of memories, this is what I learned on. I always liked a tri plex, but was never very find of a quad. Wouldn't want to make a living with either one noe'
This tri plex Mack brings back a lot of memories, this is what I learned on. I always like a tri plex but was never very fond of a quad. Would not want to make my living with either one now!
@ohbill1 You're right. I had a duplex and had to shift gears at the same time with both hands. Left arm thru the steering wheel. The real fun came when you got a triplex. Oh, the good old days.
Mack has always been my favorite truck. I cut my teeth on a my Mack many years ago. The coolest I saw, was a B model, cement mixer, had 3 sticks, which would be equivalent to the 15 speed w/deep reduction. I drove an early R model 2 stick, 5/2 with the Mack 350. Could pull like crazy. Also drove some gas powered tandem dumps with a 5 and 4. These things were crazy, you couldn't keep the rev's up like a diesel, so had to be spot on with shifts. Great experience.
@transamfan81 I drove one of these back in the 1960's (Concrete Truck) and later had a DM with a Maxidyne transmission which is 5 on the first stick and hi, low, netural and reverse on the second stick. Low was mostly off road. On road even with a heavy load, start in third on the lowside and go to first on high side and on to 5th gear. Later with an R, only one stick with hi, low, n and reverse on a switch. They put me in a KW a couple years ago. Back to Mack (Granite) but with Fuller damn it.
well that pattern sure looks like a 4x4. i can tell ya one thing. you know what your doin. thats classic to stick your arm through the stering wheel. lol
I started learning how to drive a quad box. We got this Mack B81 water truck and it's tough ol' girl. I leave it in 1st gear, but I'll use the low/low, low split, high split and then direct. I still can't figure how to shift into 2nd, though.
I remember starting at a company and they sent me out with one of these in the city, 1st reaction WTF? lost it and had to stop and start again, never got enough time in it to learn before I got a 13 eaton thank god. That old Mack was a strong old bugger to. No power steering or air ride seats. No wonder women didn't drive in the old days, no disrespect but it took alot of strength to back up in tight places
That is a quad box 5x4. The lo lo shift is usually not used. The triplex box has the main and compound sticks reversed to the quad box. ie: main lever on left, compound lever on right.
It is a quadraplex 5 and 4 otherwise known as a compound transmission. The benefit is that you have lower shifting increments so you don't lug the engine and burn up as much fuel between gears. Think of it as having two transmissions side by side. You shift the first into 1st and then through 1,2,3,and 4 on the second. Then the first goes into 2nd gear and repeat 1,2,3,4 on the second shifter.
4 stroke trucks with a sufficient torque band to overcome a bigger gear spacing, would burn less fuel when you dont interrupt the power as often, because you dont have to re spool the turbo.
Modern trucks all go back to 12 speeds. They had a need for 20 speeds because of the Detroit 2 stroke with narrow torque band, and in Europe they used a maximum of 16 speeds because the older turbos didnt give such a wide torque band. Modern trucks have VGT turbos and they are more efficient with just 12 spd
Nice vid on handling the TRT/TRQ with a light load. The TRQ-77 has me wanting to figure out what shoehorning one into a Cummins 6BTA5.9-powered Dodge BE2500 4x4 entails---I've had it with the TF518.
I drive a B model as well and I got to say that was very smooth shifting, and no clutch! But you should have not skipped gears. It confuses the green drivers.
at 0:57 are you starting off in 3rd under or 1st under? I don't know what the ratios are but 3rd seems very high from a standing start, even when bobtailing.
Yes, 3rd under. The truck has 4.62 rear gears and starts very easily in 3rd. With any kind of hill I'll go up to 2nd. As long as I don't have to ride the clutch, it's low enough.
All American trucks over 18,000 lbs use diesel engines. SOME trucks under 10,000 lbs use gas, such as the Isuzu NPR or a Ford cube van. Then there are some much older trucks over 26,000 lbs that have gas engines, like a early 80s Ford LN or a IH S1900.
Hey I'm trying to follow the shift pattern on this thing, I always get lost. I would love to play with one of these but it looks like it would take some practice and getting used to.
The right hand stick is the main box, with a dog leg H pattern, ie first is bottom left. It's a 5 speed box with wide ratio gears. The left stick is the compound box, basically a 4 speed splitter. Top left is ultra low, bottom left is under, bottom right is direct, top right is over drive ie a U pattern. ultra low is a crawler gear and not used in the shifting sequence. The actual sequence depends largely on load, and grade. It's possible to skip gears, particularly low down, if bobtailing.
I just began driving an Older Mack with a maxidyne, and a dual stick. I only use the low side when I'm loaded and only 1st or 2nd. You find that 3rd Lo is like 1st high so there's really no need. truck on COAL haulers..
Sorry, can't help you on that question. I just posted the video on Youtube. I took it on a trucking forum about 5 years ago. I think the real driver of the truck already made some comments here. Look for the user 59mack.
beautiful job with that duplex. Hard to believe that nobody has yet noticed that most, if not all, of the shifts are done without clutching! I learned on early 1950's binders with non-synchro trannies
And to think that 'kids' these days are learning to drive big trucks with automatics!! I learned on a 10, Super 10, and 15 speed. The old Road Boss I took my DOT test in was barely roadworthy, and had air steering, but I passed in 1994. Been doing it ever since.
I'd love to try to drive a B-model sometime, but don't know anyone who has one..
Thats the same thing I said when I watched the video. These guys and gals come out of school and get right in the big condo, some with auto. I learned on a 56 B model in 79, the truck was a year older than me. And I'm still at it today.
My mother said that if I did'nt stay in school I'd be digging didtches.
Thank god for overdrive and range swithces....to have to select a range with a second lever in heavy traffic would take hours of practice....you think they would put the range selector as a fouth pedal or something easier back in the 70's....
What got me into trucking was an Uncle who lived across the street and when he came into town i'd ride along with him. He taught me to drive an old B-62 MAck .. that was 40 years ago, I've been driving for 34 years now and still look forward to going to work..
Had the fun of runnin a 5 an a 4 that was bout wore out you dont put it in the hole perfect you stick it an only way to free it was crawl underneath with a baby sledge.
I know to find one that works, either A.your going to find that needs some serious rebuilding or B.Pay outta the booty hole for one that works and the better it works the more your paying.
great to see a twin stick box bein shifted the right way! leave the (one arm through the wheel) method to the cowboys! first bad road and your arm is broken! lol
mack248man i used to work for a company called cannys carrying company in wangratta they had a few old b61 out the back etc might be what ya looking for possibly cheers
okay, so you know how on like a 10 speed there's 5 gears, split it, then 5 more? well this one here i think is a 20 speed (maybe 15, but we'll go with 20). there's 5 direct gears on one shifter, and 4 gears (Low low, low, high, overdrive.) on the second shifter. say you start in the Low gear. you have 5 gears in there. then once you use the 5 in low, you shift back to first on the direct shifter, and put the second shifter in high. then same while going into overdrive.
real trucks are manual, forget the clutch you only need it to start and shift to reverse, It's all about R.P.M.'S, Gotta love the Mack Compound Transmission!!
Haha. I won 50 bucks of friends because they didn't believe I could drive a car without a clutch. Not too many people outside the trucking and mechanical trades know the finer points of trainsmissions.
Clutching is the most important part of shifting a NON-SYNCRO gearbox.....IF YOU LIKE DOING A WHOLE LOT OF WORK FOR NOTHING!! HAHAHAHA....to all your real drivers out there...keep the wheels spinnin' and the beavers grinin'
The person who said " you should step on the clutch while shifting" Obviously knows nothing about semi trucks. I mean I always wondered why the shifter always made grinding noises when I tried to shift!! Thank you for clearing that up for me! HAHAHAHAH
No need, if you shift gear at the right RPM, the gears will be synchronised. You can shift like this in a regualr car too, but it's not necessary, because regualr cars have a synchronised gearbox.
I never drove a B model that had power steering,offroad if you hit a rut, the steering wheel and wing window would try to amputate your thumb,verry painful.
ok i know how to drive a manual and what the differences are in a splitting a gear and taking a whole gear is but is the stick closer to the driver is that the splitter and the stick farther from the drive that the whole gear right? Awesome driving the only other person I know who could drive a quad box is my father.
cool thanx. Love the sound of diesel, keep them road a rollin a them trucks a truckin guys. Thaks for being there to drive and demonstrate the simple to simplistic.
My dad did the same thing but I never got a chance to drive one and did you notice that the driver was not using the clutch! now that is how you do it.
Yes, the only time I use the clutch is in reverse, and starting out forward! I call it floating the gears. It's nothing special, lot's of people are able to do that. In a few more years I think all big trucks will have automatic transmissions in them. You see more and more everyday now.
No mames, es la 4 y 4, k tiempos aquellos, dice mi jefe que jalaban de poca madre esas transmisiones, estiraban parriba como demonios, na mas no correteaban.
does this have a maxidyne motor in it? I never heard this sound before. It almost reminds me of the 262 cummins where it had a big turbo and didnt build much boost psi.
good changes man this transmission is like of 4 and 4? I saw one of those but with knob air with a single lever good video greetings from chihuahua mexico!!
Anything about the truck, engine, transmission, etc. you can ask directly to 59Mack. He is the owner of the truck in the video. He already posted some comments here. I just uploaded the video on You Tube.
I've heard a lot of storys from guys who used to drive quad boxes and they say it was common practice to put one arm through the spokes of the steering wheel so they could change both sticks at the same time and still keep the steering happening.
Yup. You can see in the picture the lever closest to him gives small changes, call it under/straight/overdrive. The one on the right is a 5-speed with larger changes. So you can go 1-under, 1-straight, 1-over, 2-under, 2-straight, 2-over etc 3x5=15 speeds. Watch the video "Quad Box Shifting" starting at 2:20 he goes through (almost) the whole sequence.
Yes! A lot of the older trucks had setups like this. I drove a '69 international that had a 10 speed main transmission (5 speed with air operated high/low range selector), 3 speed secondary transmission (with a little driveshaft inbetween the transmissions) and an air operated 2 speed rear axle, making a total of 60 forward and 12 reverse gears! Normally you just shift the 10-speed and use the others as conditions require.
WOW! (I've heard of setups like that. The older midwestern Rocky Mountain three trailer and Australian 12 or so tailer trucks 60 years ago had to have had a lot of gears).
yup, that's how you move 100,000+ pounds with an engine that is no more powerful than the average pickup truck. This particular truck had a 318 HP 8v71 detroit diesel. The older trucks could do some mighty big jobs, they were just (very) uncomfortable and slow. You're shifting all day just like this guy.
correct. I was talking about the 69 international I mentioned in my earlier post. I know for sure it had an 8v71. Yeah you can tell the sound of a jimmy from 20 miles away.
my dad always tells me how he used to drive one of these back in the day looks like a pain in the but but i guess once a person knows wich stick to shift at the time i gues it would be ok i wonder when a person comes to a stop and starts back up you have to set both sticks again from the beginning ?
It's not terribly difficult it just takes a lot of practice.. LOTS.
All you're doing really is splitting the gears.. it's like a 5 speed but with 4 ranges: Low-Low, Low, Mid, and High. The lowest of gears you really don't use, but once you get rolling it's just a matter of using momentum and splitting the gears.
It's just like a newer 13-18 spd, only instead of flicking a little lever on the stick(to split gears) you have to move a lever. Same principle, different action.
Actually this isn't an aux tranny unit. That's more like a five-and-four.. which is essentially two transmissions, one behind the other. This is all inside the same unit, with two sticks, but one transmission. Mack's unit was a little different. It was a 20 speed all together. See my comment above. I've a lot of family that used to drive stuff like this at one point or another.
Like I mentioned, it's a "married unit", but the 3spd is "like" a aux. You use it to split the 5 spd main. They are bolted together, though separate boxes because that is how they configure what was ordered. 5spd main box(either straight or OD), then bolt on 2,3,4 spd on the back. They made 9-18 spds depending how the ratio's worked out between the two boxes.
This truck has a 5x3 in it, I know this because it's my truck.
Just to clarify, that display by 59mack was as good as I,ve seen.

before there were air shifted compounds(like the typical 13 spd), you had to do it manually, thus a second stick.

And to think that 'kids' these days are learning to drive big trucks with automatics!! I learned on a 10, Super 10, and 15 speed. The old Road Boss I took my DOT test in was barely roadworthy, and had air steering, but I passed in 1994. Been doing it ever since.
I'd love to try to drive a B-model sometime, but don't know anyone who has one..

Thats the same thing I said when I watched the video. These guys and gals come out of school and get right in the big condo, some with auto. I learned on a 56 B model in 79, the truck was a year older than me. And I'm still at it today.
My mother said that if I did'nt stay in school I'd be digging didtches.
Boy was she wrong.

Thank god for overdrive and range swithces....to have to select a range with a second lever in heavy traffic would take hours of practice....you think they would put the range selector as a fouth pedal or something easier back in the 70's....

What got me into trucking was an Uncle who lived across the street and when he came into town i'd ride along with him. He taught me to drive an old B-62 MAck .. that was 40 years ago, I've been driving for 34 years now and still look forward to going to work..

why is there two shifters?
daaaveed 3 years ago
This is before "air shifted" range boxes. You had to do it manually. The new trucks is all air controlled by switches on the shifter handle.
59Mack 3 years ago
okay, so you know how on like a 10 speed there's 5 gears, split it, then 5 more? well this one here i think is a 20 speed (maybe 15, but we'll go with 20). there's 5 direct gears on one shifter, and 4 gears (Low low, low, high, overdrive.) on the second shifter. say you start in the Low gear. you have 5 gears in there. then once you use the 5 in low, you shift back to first on the direct shifter, and put the second shifter in high. then same while going into overdrive.
dant387 2 years ago
That's backwards. The 5spd is the main box, you split each of those with the compound(left stick) of 3 spd-lo, direct, hi.
1st lo, direct, hi-then 2nd lo, direct, hi, etc.
The video is kinda hard to follow as I'm skipping ALOT of gears along the way.
59Mack 2 years ago
Incorrect. You split each MAIN gear, not the other way around. 1st LO, 1st Dir, 1st OD, 2nd Lo, 2nd Dir,...ect.
This truck(mine by the way) is a 5x3(15 spd).

59Mack 3 years ago 3
If you're not precise enough and grind the gears, it's a better idea. Rookies are better off clutching in the beginning.
teamwounder 3 years ago
No need, if you shift gear at the right RPM, the gears will be synchronised. You can shift like this in a regualr car too, but it's not necessary, because regualr cars have a synchronised gearbox.

ok i know how to drive a manual and what the differences are in a splitting a gear and taking a whole gear is but is the stick closer to the driver is that the splitter and the stick farther from the drive that the whole gear right? Awesome driving the only other person I know who could drive a quad box is my father.

Yes, left of compound, right is main box.
Some trucks were swapped around.

arubberball 3 years ago
My dad did the same thing but I never got a chance to drive one and did you notice that the driver was not using the clutch! now that is how you do it.
cnrailman2 3 years ago 2
Yes, the only time I use the clutch is in reverse, and starting out forward! I call it floating the gears. It's nothing special, lot's of people are able to do that. In a few more years I think all big trucks will have automatic transmissions in them. You see more and more everyday now.

I've heard a lot of storys from guys who used to drive quad boxes and they say it was common practice to put one arm through the spokes of the steering wheel so they could change both sticks at the same time and still keep the steering happening.

Is that the same sort of thing with tractors where one lever is ranges and the other the gears
numptybaws3 4 years ago
Yup. You can see in the picture the lever closest to him gives small changes, call it under/straight/overdrive. The one on the right is a 5-speed with larger changes. So you can go 1-under, 1-straight, 1-over, 2-under, 2-straight, 2-over etc 3x5=15 speeds. Watch the video "Quad Box Shifting" starting at 2:20 he goes through (almost) the whole sequence.
castirondude 4 years ago
Its like 2 gear boxes one behind other on the line(axle) ??
staszekalkatraz 4 years ago 2
Yes! A lot of the older trucks had setups like this. I drove a '69 international that had a 10 speed main transmission (5 speed with air operated high/low range selector), 3 speed secondary transmission (with a little driveshaft inbetween the transmissions) and an air operated 2 speed rear axle, making a total of 60 forward and 12 reverse gears! Normally you just shift the 10-speed and use the others as conditions require.
castirondude 4 years ago 2
WOW! (I've heard of setups like that. The older midwestern Rocky Mountain three trailer and Australian 12 or so tailer trucks 60 years ago had to have had a lot of gears).
SteveCarras 3 years ago
yup, that's how you move 100,000+ pounds with an engine that is no more powerful than the average pickup truck. This particular truck had a 318 HP 8v71 detroit diesel. The older trucks could do some mighty big jobs, they were just (very) uncomfortable and slow. You're shifting all day just like this guy.
castirondude 3 years ago
if you listen this is a straight 6 mack not a V-8 a detroit would be louder and screaming.
dshine55 3 years ago
correct. I was talking about the 69 international I mentioned in my earlier post. I know for sure it had an 8v71. Yeah you can tell the sound of a jimmy from 20 miles away.

my dad always tells me how he used to drive one of these back in the day looks like a pain in the but but i guess once a person knows wich stick to shift at the time i gues it would be ok i wonder when a person comes to a stop and starts back up you have to set both sticks again from the beginning ?
dunn98632 4 years ago
It's not terribly difficult it just takes a lot of practice.. LOTS.
All you're doing really is splitting the gears.. it's like a 5 speed but with 4 ranges: Low-Low, Low, Mid, and High. The lowest of gears you really don't use, but once you get rolling it's just a matter of using momentum and splitting the gears.
GrEmLiN76X 4 years ago
It's just like a newer 13-18 spd, only instead of flicking a little lever on the stick(to split gears) you have to move a lever. Same principle, different action.
59Mack 4 years ago
So what is it, 4 ranges with 4 speeds?
ntxic8td 4 years ago
5 spd main box and 3 spd compound(aux). The Mack tranny is a married unit.
59Mack 4 years ago
Actually this isn't an aux tranny unit. That's more like a five-and-four.. which is essentially two transmissions, one behind the other. This is all inside the same unit, with two sticks, but one transmission. Mack's unit was a little different. It was a 20 speed all together. See my comment above. I've a lot of family that used to drive stuff like this at one point or another.
GrEmLiN76X 4 years ago
Like I mentioned, it's a "married unit", but the 3spd is "like" a aux. You use it to split the 5 spd main. They are bolted together, though separate boxes because that is how they configure what was ordered. 5spd main box(either straight or OD), then bolt on 2,3,4 spd on the back. They made 9-18 spds depending how the ratio's worked out between the two boxes.
This truck has a 5x3 in it, I know this because it's my truck.
59Mack 4 years ago 2
Does'nt look like driving a twin stick would be very bad once you got use to it.
