PACCAR

[daugen]

It seems the Dutch own Kenworth and Peterbilt, which I guess is ok, the Dutch
sure do have a touch for quality, that's where Feadships and most historic high end megayachts have been made.
The Dutch motorboats/yachts I have been on were pretty remarkable, the quality was so evident, the construction so strong.
And DAF I believe designed one of the first CVT transmissions.

But what are Paccar engines? What is their lineage?
Are they rebranded somethings or a unique engine to themselves?
Does anyone other than Kenworth and Peterbilt offer them in their trucks? Heavy machinery?
Just curious and I'm sure one of you know.
thanks

A lot of the Kenworth trucks are built here in Chillicothe including their newest model, though I can't think of the model name right this second. Traditionally you could get about any engine you wanted in one, but Paccar never built their own engine. That changed a year or so ago. Paccar designed and built their own engine. Everything I've heard has been good about it. Decent fuel mileage and no major problems so far. And with this being a small town, if Kenworth is having issues, everyone knows it.

umm, it's the other way around. paccar is an american corporation that owns the kenworth and peterbilt truck lines in the united states, daf trucks in the netherlands, and leyland trucks in the united kingdom.

But what are Paccar engines? What is their lineage?

the class 8 truck market used to be based on the concept that one could order pretty much any major component from any of the major truck manufacturers, ie one could order cummins engines and dana axles in kenworths, peterbilts, internationals, etc. these days, life has become much more segmented, with just about every major manufacturer building their own engines, transmissions, and such. basically, all the manufacturers have become like mack.

the paccar engine is new on the american market and i believe is only available on paccar products. paccar's daf subsidiary has been building diesels for many years so i would presume that the technical foundation of the american diesel is based upon the daf engine.

Thanks. It wasn't clear from their website.

Not quite.
As far as I know, most transmissions in American Class 8 trucks are RoadRangers (Eaton). Every now and then, you'll come across a Spicer (Dana). Same with drive axles, usually Eaton or Dana. That's about it, except for the Macks.

I think, not sure, the Paccar engine is very close to a cummins.

When I saw the cylinder heads, that's what I thought of too, but then some Ivecos and other diesels do also.
Probably some common dna, though everything now has to be high tech, common rail, etc.
There isn't a motor I don't find interesting, and this engine is just one I wasn't familiar with. Is Mack still making a unique engine?

 

[dhagood]

bigfoot62, meritor also makes class 8 axles. meritor also makes transmissions, although the last i heard was that they have stopped selling manual class 8 transmissions in order to concentrate on class 8 automatic transmissions.

wnc3, just about all the class 8 truck engines resemble each other. they are just about all 6 cylinder turbocharged engines of various sizes from 11 or so liters up through 16 liter displacement. paccar building their own engines directly cuts into cummins market share. cummins is now pretty much odd man out at this point. paccar (kenworth and peterbilt), mack, volvo, freightliner (detroit and mercedes-benz) all make their own engines for their trucks. as far as cat goes, the last i heard they were getting out of the class 8 engine market. i don't know if that ever actually happened.

Yep. Mack Powertrains

I'm aware of Meritor, but don't actually know of anybody that has one. :confused3: But, my KW has a Meritor air dryer on it, if that makes you feel better.

IIRC, the only way to get a CAT engine in a new Class 8 truck is to buy the CAT truck. CAT CT660

 

[dhagood]

i've driven a number of volvos that had meritor axles and meritor 10 speed transmissions. i didn't like the transmissions very much for a completely idiotic reason: i hate the gearshift knob. the center section had a meritor logo in a plastic cover. after a number of years, the cover would either crack and irritate the palm of your hand or the cover would fall out and be even more uncomfortable to hold. i much prefer the eaton shift knob.

the longevity of both axles and transmissions were as good as eaton; i have no idea of the cost differential.

and that's the first i've heard that cat is making their own class 8 truck.

i wonder what cummins is going to do? i have a lot of miles sitting behind cummins engines.

Cummins has just teamed up with Navistar again, now that International has abandoned their enhanced EGR exhaust treatment (after major loss of market share and realizing they couldn't meet EPA targets before using up all their credits). ProStars are just now being built with ISX engines with SCR (urea after treatment), with other models of trucks and engines to follow later this year. International had been using MAN - based diesels for their 13 litre engines and were working with CAT on an enhanced EGR version of their venerable 15 litre engine, before they gave up on that whole idea. Of course, International continues to build all their smaller engines. BTW, the CAT truck is based on a highly modified International Paystar. There's been speculation in the trucking magazines about Navistar being a takeover target for Scania and Volkswagen!
Back to Paccar, I believe the small engines used in their medium duty trucks are really re-badged Cummins.

Cummins head design (well more accurately I suppose their valve covers because that's what you see) are pretty distinctive so the Paccar
I saw looked pretty similar. I'm more used to seeing the Cummins in boat engine rooms, they are extremely popular in boating, have a great reputation,
and battle neck and neck with Volvo and Caterpillar all the way. And usually Cummins wins, unless someone wants the Volvo's integrated propulsion system, a lower tech pod drive.
It's been my experience that Cat owners are very loyal; if they had one boat with a Cat, they wanted their next one with it too.

So I guess we'll see more of Paccar.

I've been drooling over motorhomes, not my time yet, but seems the diesel pushers are all either Cummins or Cat. In the 300-400 hp range, not sure
either engine has an advantage, both seem very premium.

And just to make things more confusing, the CAT truck is actually designed and built by International ...

Where did you hear that or see that?

It's true.

The Caterpillar CT660 is actually built by Navistar, who builds International Trucks. It’s a new set of clothes on an International, to appeal to a whole different audience.

 

[QRTRHRS]

Not sure but I was thinking that the Paccar engines came from DAF or a DAF subsiderery?

 

[dhagood]

This would seem to confirm that paccar engines are technologically linked with daf engines.

Back to Paccar, I believe the small engines used in their medium duty trucks are really re-badged Cummins.

I always thought the PACCAR 6.7-liter was a rebadged Cummins since they looked almost identical in pictures I've seen.

In this global economy, it's tough to know who is in bed with who so to speak.

sure does, since 2006 they seem to have put their stamp on the PACCAR engine.
interesting history, very entwined in recent years with Leyland
