Why is Kenworth using Paccar if their reputation is so bad?

Your probably right, but even with a Glider you are limited on engine choice, with a true custom truck, like a Marmon, just about anything was possible.

 

I bought a new '15 cascadia evo after experiencing many problems with the 450 Cummins so why would you think a Paccar is going to be any different? FYI I had lengthy conversations with the folks at Freightliner and surprisingly they had some new freightliners with Cummins engines. However they were trying to off load them by giving a $10K incentive. They told me that there are many flaws with the Cummins especially the piston design which has resulted in poor oil consumption. I wouldn't be surprised if a Paccar engine is just the same as a Cummins with a different name stamped on it.
IMHO I wouldn't touch a Paccar, as it seems that they want to hide the apparent flaws in their engines.
at least Detroit has designed their engines from the ground up to accommodate the emissions and I can concur with the gentleman. Their extended warranties are excellent value. I bought a parts and labor package that takes care of the major components for the next 5 yrs.
but I can understand guys loving the quality build of the Kenworth but that engine is its downfall.
Caveat emptor. Good luck.

 

they have to, they earn more money on that way, this is in house engine,

paccar engine is actually daf, but sold under name paccar because otherwise nobody would buy it in US, here they are also called paccar and being on market since 2006

in future you NA guys can expect lot of "strange" moves from manufacturers that are already normal here for decades , all for their own profit

 

How does the DAF perform in Europe? What I am getting at is the problem the motor proper, or is it more the conversion to NA emissions/electronics that is the problem? Same goes for the MAN/International Maxxforce? Is it the platform? Or the crap they are hanging on it?

Thanks Stan

 

Paccar is a B-10 while Cummins and Detroit are B-50s. That means that the Paccar has a ten percent chance of a catastrophic failure while the rest have a 50% chance. The Paccar is simply a better made motor. I've had Paccar since 2011. No major issues with the motors themselves.

 

People think the Paccar MX is a young engine.
It isn't.
First ones were sold in '06.(not in USA)
Mechanically sound,no better or worse then a Volvo or Freightliner,in my opinion.


The thing that bugs me is people who put down a engine when it is the emissions hardware that fails them.(doesn't matter if it a Volvo,Detroit or Paccar)
And those are mostly outsourced by truckbuilders.(ironic when you think about it as most on this forum are in favor off more outsourced parts on trucks)

Hegemeister,if you don't feel comforteble buying a Paccar,then don't.

And if you look at my name you will know what engine i have.
I like it but other don't share that feeling.

 

I have a 13 kw T660 with the Paccar motor have had no issues with it at all other than when new just some software issues in the ecm. but now has over 400K and running good life time fuel mi is 6.56 running 90% over 70 mph. I do my own maintenance very easy engine to work on overheads, servicing ect. does not use oil at all does not leak. As with any of the new engines it doesn't have the throttle response because of emissions. but the power is there it's smooth and linear. very happy with it.

 

From my experience, cummins is the best choice. Our cascadias with DD13's are constantly in the shop. Our paccar engines are gutless, 455 horse with 3.70 rears, and it gets beat by our lower powered dd13s, and the dd13s get beat by the one truck we have that has a cummins.

Our trucks are leased and our mechanics love the cummins since it's only been to the dealer twice for emissions and once for the transmission. While our other trucks have been to the dealer many more times.

We have one truck with a paccar engine that has been to the dealer on monday, come back on Wednesday and went back to the dealer on Friday. Luckily any kws they buy in the future will have cummins engines

 

hm, hard to tell
daf before used copy of layland engines, so daf dont have longest experience on market with engines , also they maybe dont have enough money to develop this good

also i think daf did not know where are real limits, of this engine,

when they first arrive in 2006 , most of those engines were recalled here , they had enormous oil consumption like no other engine before, daf fix that problem without charge, even after warranty

even after rebuild some engines continued to use oil , they have turbo problems, many trucks here did not manage to make 500 000km with one turbo , many had problems with last cylinder
after rebuild here daf reduce turbo pressure to 1.4bar , they got orders from NL,

my cousin run 3 of them ,dont know how much they km now, but around 550-700 all 3 , one is import used recently, other are bought here new

2 of them were opened twice and everything on upper side changed so far , third one had oil in exhaust after scr , i did not talk with him about this he is now in california
after rebuild on next service in daf , they reduce power , so fuel economy rise up to unreasonable 45-47L/100 5-5.2mpg , he was writing to daf NL, and complaining about performances and fuel economy and they allow daf service to return power, and he get 1.9bar pressure in turbo

his trucks are mostly loaded to limit (88200) or sometimes higher 90-92k
he run mixed between highways , and offhighay( highway dont exist there) those roads include lot of hills, 10% 6.5mille is not uncommon
here road infrastructure is still not good, on many routes you have climb up and down , roads are curvy....

and they have only thing in mind, to make 3 roundtrips per weak to italy, , normally you would make 2 , some guys are even making 4
3trips mean you can sleep 5-6hour per day, you must cheat on tacho to fit workday in 15hour in other words in constant grey zone
they drive as fast as they can,they dont respect any traffic rules, they dont secure load as this take time,

as for MAN, this is certanly not best engine on market, both in fuel economy, and lifetime, man have their own deseases, but it is not bad as you guys are writing, so i guess this is all maxforce problem

they go here very well , also MAN have very cheap parts, for example turbo cost only 800€ , common rail injectors are 260€ , water and air radiator are between 700-750, pistons from 200-240€ , cylinders 70€ , alternator 350€,starters are expensive 620€ for older man are 320€ dont remember other prices , but you can get good quality parts non original for even cheaper,
