I have a few questions about motors.
In over the road applications which motors are more reliable Detroit cat cummins Mack? For some reason I have been interested in big trucks and the performance aspect of it. To me it seems like most people would prefer a 6nz or c15 c18 over a isx or 60 series. Do they last longer,? More power?

Cat is typically longer life span before an overhaul is due.
Isx Cummins aren’t even suitable for boat anchors they are so worthless. Detroit’s given they are the correct engine, you’ll find some that love them and some that hate them. I’m a cat guy, however I do like Detroit as well. 6nz is just a serial number of c-15’s. They are over rated if you ask me. Easy to make decent power with. There’s really nothing wrong with a good emodel cat either. The bottom ends just aren’t as stout as say an accert engine. I know nothing of Mack engines so I’ll bow out on that one.

The only acert exp i have is a c18 acert and a 32 acert in boats. The 32 is a monster. You wouldnt think that about cummins, maybe its just the isx. I know the m11 use to pop heads and our brush trucks have 855 in them, yeah

Mack can be hard to find parts for, depending on where you live. The 12.7's are good engines, Detroit seemed to be the only ones that could figure out how to get a 12 liter to make power and stay together. The 3406e/early c15 is cats best work, imo. They're reliable and tough and don't require any fixes to work well. The later ones are good too, but they can take a few dollars to get right.

To each their own really. Used to be everyone liked one engine and that was it. Now it seems everyone likes any pre EGR engine regardless of color. Detroits were reliable cheap to rebuild but leaked oil and were a bit gutless. Cats cost more to rebuild had a tendency to last a bit longer and pulled like freight trains.
Give you an idea my dads volvo d12b has over 2 million miles on it the head has never been off. You would never get that with an EGR engine. |
Still calling BS on the Volvo engine just as I did in the other thread.

No one wants any emission motors.. in light duty heavy or medium. I think the maxxforce 7 is possibly the worst engine ever built.. (6.4) put in the terra stars or what ever.
Do all the semi truck amd ag equipment have the same issues with the dpf systems like big 3.? It also seems to be harder to delete medium/heavy duty ( as far as finding tuners to re flash the ecm and piping ) |

They are also a joke on marine side. Easy to make power though because C18 marine parts fit C15 and 16. |

I have a few questions about motors.
The idea that Cats cost more to rebuild is complete BS spread by people that have never priced parts from other brands. An actual Detroit head is almost $2000 more than Cat. Cummins parts are almost always higher. Cat injector is $100 cheaper each. Maxxforce in any size is the biggest pile on the road. The easiest way to tell what’s good is look at selling prices. There is a reason the Mack/Volvo/Maxxforce powered trucks sell just over scrap price. Internet option is one thing but when people are asked to put their money where their mouth is honesty comes out.
You get a truck with a Cat/Cummins you can get parts and Service anywhere. Try that with a Volvo. And to make matters worse the only way to get a Volvo Motor is to drive a Volvo. |
You guys are amusing comparing d13s to d12s. Theyre completely different engines.

No I’m not. Check TruckPaper genius and look at how cheap they are. Such an amazing engine you have to take a bath on at resale. You would be amazed at the people around here that owned S60’s with good luck and went out and got a newer DD15/13 thinking they were getting the same engine. Only to find out Detroit got infected with European stupidity. “Built like a Mack truck” is now followed up with laughter thanks to the same infection. |
I don’t know much about heavy duty motors except the ones I used to deal with in the Army. I believe they were all D60 series, supercharged and turbocharged. They were dogs.
Anyway, as I’ve been looking at motorcoachs and toters I’ve found that Volvo’s have the highest resale value and freightliners with Cats or Cummins are less valuable and Mercedes seem to be the least valuable. Any thoughts? |
