I.S.X. OR CAT ?
 

ANYONE?

isx

between those two chooses CAT

What year?
It's always a CAT for me, but i've been advised, by CAT dealer folks, not to buy 2007 CAT, and wait at least a year, too many complications... :roll:

Cat
What's up with the 2007?

My dispatcher decided to start driving again, so he is taking an o7 pete with a new engine... we do not know what engines are coming... some I.S.X. SOME CAT. I'm glad to take a bridge c 15 till we sort things out...

I don't think anyone knows, anyone tell us? every one I know wants a 06 engine

There is to many emission "improvments" on it, and too many things, could go wrong...not quiet tested yet! :sad:

that always seems to happen when they raise emission standards

They're all going to be more complicated, not just CAT.

Either way, no post 2007 truck for me for many many MANY years.

Same as ALL of the '07 engines... DPFs, new technology. The new 07 CATs have a spark plug, ignition coil, and fuel injector in the exhaust system. The DPF is an oxidation catalyst as well as a particulate trap. An electronic exhaust system with inlet and outlet pressure and temperature sensors to trigger catalyst regeneration.

Oh, and a closed crankcase, too... no more draft tubes.

'07 (DPF) enignes are NOT available until 01/07... because truck manufacturers are not forced to install them until then.

[quote=solo379]The exhaust and closed crankcase are the only visible changes...

WOW :shock: I wish I could talk our shop Foreman into swapping out engines, I'll take a regular C15 please, just think of the better auction price... My 01 Pete got sold at auction yesterday, in Grande Prarie. :cry:

just to throw in a different rub here.....its pre-03 for me. I have still not come to terms with EGR let alone all the newer crap! Just keep rebuiling as long as you can!!!

CATs didn't have an EGR, till 2007, and frankly, i'm quiet happy, with my Acert...so far(246,000) :roll: :D

Just to clarify... DDC and Cummins got EGR in the fall of '02 (octoberish).

CAT isn't using EGR at all... they will be using CGI (clean gas induction) in '07.

The difference is where the gases are routed from. The "dirty" gases from the EGR engines are the cause of most of the EGR valve failures.

Cat.

Cat is crap !
Cummins ISX is now a proven engine and totally compliant !
The ISX `07 has a better built EGR valve, located farther down stream and made by a different manufacture. The biggest change is a serviceable muffler ( that means it can be cleaned ... not replaced ).
The `07 Cummins ISX is a highly superior engine ... and moving up from a very good foundation !

CAT SUCKS (then they blow up).

an old E6 300 mack 8)

Cummins ISX !! The CAT twin turbo sucks .

Did you ever drive one? :roll:

We just took delivery of our 2006 International Eagle with an ISX motor.

Beautiful and smooth power.

I will let you know how good of a choice it is in about a year.

Where ya been Rockie? I was lookin for you last week, heard about some wrecks on the hill, just rumors...? I only drove an I.S.X. 1 day, I liked it. Just as good as a CAT :lol: I had an accert 550 for a year... :cry:

It was a sad year... That was a 04 ? maybe beter now ? I like the c15 550

We have been crazy busy at work. I have been getting the new tractor operational and working on getting it working on our new thing.

We are going to use it to train new drivers with 140,000 lb Super Trains. It still will take some work to get it going, but it is our new direction and I want to make sure it is done right so we can get the effect out of we want.

Wrecks on the hill... ? I also wanted your opinion on the 1.8 meter high signal light rule that we have, not allowed over 1.8, 5.5 ft... every tractor around here is (non compliant) THESE are the only lights visible in weather? Idiots! ie. Headache racks... Frieght shakers come with, on the mirrors...

OUCH! Did you get bit by a CAT?

I agree as well, but to clarify... 1. Cat's acert engines ARE compliant (only "bridge engines" paid fines). Also, CAT's DPF is sericeable as well.

There was a fuel truck up there this summer that rolled over and blew up. Other than that I don't know of any others.

I have not heard of the light rule.

The super b fuel tanker, I think I know, knew him... His name was Leo, I've tried to findout online... Creston paper, Cranbrook... no luck

I have the article at work. I will see if his name is in it and if so let you know. He overheated his brakes and then drove by three run away lanes and lost it on one of the last corners before the bottom. It was a single vehicle crash. I don't know much more than that.

Thanks Rocky, :wink: notice I got your name right... duh :oops:

EGR is EGR. Because they pull it from a different spot doesn't mean they can make up a new name. But you are right, it will be cleaner.

The biggest difference will be soot. The only other "harmful" item would be sulphuric acid, and that's all but eliminated with the new fuel.

Then why was there a recall for the post-bridge engines involving reducing nox? Something about a computer reflash?

I have the "post-bridge" engine, never heard of any "recals"! :roll:
As of to "reflashing" computer, they do it every time, when you service it, and update is avable. Mostly about performance, didn't say nothing, about "nox"!

No, that's not a reflash, that's pulling the codes etc..

reflashing means changing the fuel maps etc..

Yes. It is a different between 2001 C-15 or 2006 C-15. We are se the different. Fuel , speed we are think must be the new emission or something.

I had a 2000 ISX and for the first two years (starting with the first trip) it was in a Cummins shop every week for one thing or another.Lost a small fortune in down time every week.Oh yea 2 inframes and a crate motor they would only back up for a year no more.A friend of mine has an EGR version and his is no better,I would not recomend this motor to anyone.
My '05 Cat. has had the head crack at 161,000 and I was down for a couple days out of almost two years I would say I am way ahead of the Cum'apart.

Name an engine that doesn't get reflashed regularly? Reflashing ECMs today is more common than changing oil.

The truck electorics have followed the automotive world, where reflashing is done to repair computer glitches and software conflicts... quite common and not usually of any concern to the operator.

Have you ever installed a windows security update on your home computer? How about a patch for a computer glitch you've never even noticed? Same difference.

You guys are confusing "reflashing" with "reading codes". The two are totally different.

CAT had to go in and redo some fuel maps, due to not complying with NOX standards.
