80s Mack Trucks

I am on the hunt for a dump truck to use mostly for farm duty but occasionally use in my business.
I like Mack trucks for some reason and their goofy offset cabs.
Most of the trucks I am finding have an Auto Transmission, which I'm not too fond of in a big truck like this.

I cant seem to dig up any info on them, everything I find when I search is related to their newer mDrive stuff that I doubt is relative.

Anything to be concerned about with them?

They're good trucks. They don't quite have the dealer network like other brands and they have more make-specific parts, so parts are a little harder to get.

Mack is a black and white subject. People will either love or hate them, not much of a gray area.

I cant fathom a reason to own one.

Mack, the name just says power, strength, the ability to get the job done with no extra rills. Just a solid truck!
Peterbuilt, sounds like a porn stars name.
Kenworth, sounds like some rich guy bragging.

Not sure what you are seeing autos in. Maybe ex highway dept or refuse trucks, but most r models ive known were built with a standard trans.

They are a solid truck that gets beat on harder than most. I like older Macks, and I worked for a Mack dealer for a few years. I can get in depth with what to look at if you come across one for sale. They do have some specific things that are different than other makes.

The Mack in the picture is called a Rb Mack. The trucks with the cab in the center are Rb models where as the cabs that are offset are dm models. I still have a Rb Mack dump truck. It is my favorite truck of the fleet. Find yourself a 400 hp one with the Mack super ten style transmission with low low and you’ll have one of the best dump trucks ever made. Ten forward speeds and 5 shiftable speeds in reverse. The only flaw with these trucks are they will more than likely have the Mack toploader rear ends. The axles are the fuseable link in the setup. I have prolly broke 10-12 axle shafts in my toploader Mack’s. Good luck they are fun trucks.

Get a one with a Rb air ride cab. Most of the dm where solid mounts and they shake like a mofo going down the road. There are newer ones called RD I don’t like these as much as they are more blocky and are the precursor to the cl models.

10 years ago there were tons of these guys around. They all got bought up and sent oversees to be used up. The third world countries love those trucks as the are simple to fix and run forever.

That’s a Mack super liner. It has too light of a front end prolly only 12,000. That does not have a 600 hp Cummins in it. That is a Mack e7ish engine. I would steer clear. Anything you haul in that thing will instantly overload the truck. This is probably a day cab semi the (large fuel tanks give it away) turned into a dump truck. I cannot tell by the pictures but count the number of studs on the rear axle shaft. 6 bolts are the Mack heavy 44,000 pound rear end. 8 bolts are the lighter 30-34,000 rear axles.

Here is some picture of a correctly spec’d Mack truck. This is a newer cl model. Heavy front axle. 600 non egr Cummins small fuel tanks heavy rear axles.

Lol you want it yuuuge when you pulling a 160,000 object. This guy actually has two steering boxes on it one on each side. No excuses for it not turning.

How does it turn the second one? Hydraulic circuit plumbed in parallel with the first so the piston always moves the same was as the one the steering shaft goes to?

Does Mack not make their own engines anymore? My neighbor has an older dump with the small cab. I drove it and it shook the shit out of me. If I had to drive that thing every day. Iíd need another back surgery to fuse the rest of my spine!

I'm familar with Mack RB 10 wheel dumps from the 70-80's. They were the dump truck to have here in the east.They have a repuation for ruggedness.But IHC Paystars were also popular...Even now, you still see them doing daily work...Macks seem less popular in the West...

Now a days itís a Mack/Volvo engine. My truck was ordered new with a Cummins. Mack used to sell new trucks with Cummins in them if you really wanted it today not so sure.

I drove a lot of Mack refuse trucks. They will run on 5.cyls, that I do know &#x1f602;

Were they nice? Absolutly not. I think the Mack engineers asked each other how cheap and basic they could make a cab, but my truck started every morning.

I much preffered the Autocars, as a driver.

What he said^^
I drove an offset cab for two years. Tough truck and rough on the driver.
It was the 238HP 6cyl 5 speed full Mack. one thing about them that was great was a cold start. Set the RPM for warm up and they would hold it while warming up. Unlike a Cummins bumping up to 2100 rpm.
One more thing, don't slam the door like a frateshaker.

The truck from Convoy was an RS-712ST. An RB is a setback axle R model. The offset cabs were found on the DM and were available with either setback (later) or the earlier axle forward style.

Iíve spent the last 8 years running old Mackís at work and I fucking love them. Stay away from the Mack 7 speed, itís a hunk of shit.

Mack Driver joke, SDCJ you probably should stop here since it involve Saints heaven, hell...
















Told to me by a truck driving friend back in the 80s
A driver had scrimped and saved his entire 30 + year driving career and could finally afford a new Peterbilt, done just the way he always dreamed of he was out on his first run in his new rig when he had a heart attack while parked for the night. Suddenly he was driving up this long sloping road towards what looked like the biggest truck stop he had ever seen on the top of the hill. When he got to the top there were gates blocking his way in. Setting the brakes he got out and walked over to the guard house and there stood Saint Peter!
Saint Pete says "Sorry we're full up of you drivers who always seem to buy a new rig then die", The driver was arguing with him, yeah he had run some miles he hadn't logged, taken a few pills to make a scheduled drop, maybe hadn't always been as faithful to his wife as he should, but so had other drivers, and how about his new Pete, he should be allowed in.
Suddenly an old rusty one hole Mack (Single exhaust stack for the unknowing) was coming towards them with a flatbed loaded with steel, black smoke rolling out of the stack. Saint Pete says " Not this guy again I keep telling him I can't let such a ugly rusty old truck in here it'll ruin the neighborhood."
The first driver said " If I can get him to leave do you think you could find room for me?" Saint Pete allowed how he probably could maybe squeeze him in, it wouldn't be in the front row mind you but it wouldn't be in the very back either. The driver headed out to his rig and got on the CB, all the sudden the Mack driver stood on the brakes, down shifted did a U turn and headed back down the hill gathering speed as he went up through the gears, black smoke just pouring out!
As he pulled through the gates Saint Pete asked him "How did you do that?"
"Simple was the reply I just told him the scales were open, and you know those steel haulers they would rather go to Hell than cross a scale!"

think of the plumbing like using the second box as just a hydro assist cylinder and idler arm. There's no screw in it, just the hydraulic piston
