Cummins not highly thought of in OTR trucks

[Blakers]

The EMDs are still mostly 2 cycle, though they are offering some 4 cycles now to compete with GE.

The old two cycle Detroits were a blast to drive, love that sound! But the best, most fun to drive truck engine was the old 2 & 6 bits (275) Cummins. I have one in a 1965 Kenworth offhighway truck mounted under a hydraulic log loader. They have a roots blower mounted on the right hand side of the block, with a back-draft exaust manifold. The sound pulling is awesome and at night they will stand about a foot of fire out of the stack. If you run a straight pipe, they have been known to break windows in towns with narrow streets, especially on the jake. These engines were very popular with or without the blower in all HP ratings. The next model engine, the 855 was also popular. I liked the big cam 3 the best. The models after this I know very little about, so can't say.

How many of you guys know that all most all of the detroit 60's that are in SWIFT (slow wagon in front towing) trucks are build by Mercedes in mexico.

NIsaacs,



The F350 with the Cummins transplant and 5x3 transmission in your signature looks pretty interesting! - do you have any pictures you can post?

They've owned DDC for almost 4 years ( July 21, 2000)--wouldn't be suprised to hear of a Mexican assembly plant. Almost every manufacturer builds something south o' the border. If they're in Swift's trucks, they're no doubt in many others as well.

Even those proud to be american ford boys build a few super dutys in taco land.

JStieger,



I am new to this site and not very computer literate. I have lots of pictures, but I am not sure how to post them or if I even can with my equipment. I do not know how to use the smiley faces either. I would be glad to send you some in the mail if you could teach me. Check your PM, I am going to try that. Wish me luck!

If you use the "Post Reply" button unstead of the little Reply box at the bottom of the page-



A small box with smiley icons shows up on the left side of the screen. To add one of those to your text just click on one of them. A symbol set will be entered in the text box at the END of the message.



One thing I have done is to transfer these into my word processor (Microsoft Word) and then print the whole page out for future reference. That way you can enter the symbols anywhere in your text that you like.



If that's not enough help, give me a jingle at 480 560 7460

smiley face

John,



I am going to try the smiley face, but am not sure how to get it from the little box over here! Well, the word confused came up but not the smiley face. I did find the other box like you said so I am gaining ground, but no cigar yet. If I can't get it to work, I will give you a call. Thank you for the response!

These engines have been in the Freightliner classic's and cabovers for SWIFT for 6 yrs. rated at 430hp governed to 350hp

 

[bmoeller]

Nick, If you look at the bottom of the box that has the smilies, you will see the words get more in blue. Click on it. Another box will pop up. It has the code next to it for the smiley you want.



For example, a smiley is : ) Type next to each other, no space as I did to show you.



The green smiley with the teeth showing is : D

I am an engineer at Freightliner - here is what I know that some might find interesting . .



Mercedes 4000 (12. 8L) is assembled in Brazil

Mercedes 900 (4cyl = 4. 3 or 4. 8L, 6cyl = 6. 4 or 7. 2L) is assembled in Germany

Both engines are serviced through Detroit Diesel and Freightliner/Sterling/WesternStar

Big Cummins engines are not available from Freightliner, ISC and ISL are. this is since the oct 2002 emmissions change. Due to the emmissions requirements changing in 2002,4,7, and 10, most OEM's have had to drop at least one engine supplier in order to have enough engineering resources to keep up with all the changes that are happening in a short period of time. Freightliner dropped cummins, Volvo dropped CAT, etc.



Keep in mind - at one time Freightliner offered the following in heavy engines - MB4000, DDC60, CAT C10,12 and 15 (formerly 3406), Cummins ISM, N14, and ISX. When ALL of these have major changes at the same time (dictated by the EPA) - its a huge amount of changes. Other OEM's are in the same boat and have had to limit choices. Daimler owns DDC and Freightliner, so it was down to either CAT or Cummins - I am way too low on the totem pole to know the details of why CAT stayed.

Mathew is right. I also work for Freightliner

dl5treez, nope, not a six. Big mambo Jambo . 3408

I'll be the first to say I don't know anything about big rig diesels, but I had an OTR driver tell me that Cummins nearly put him out of business. He said he had to rebuild it four times, one rebuild within a month of the last one. Then he offered that I should pour a quart of ATF into my crankcase before an oil change, that it would clean up the sludge real well.



Seems to me the two statements are related somehow. I know Cummins doesn't reccommend this practice, but is ATF in the oil done in big trucks? Is it possible that this can be done safely on some engines and not others?

Matt,



This guy must have had some kind of failure like coolant or fuel dilution of the oil for a failure to occur that quickly. Or perhaps he beat the poor thing to death right out of overhaul. The real answer to this guys plight could only be found after asking some very specific questions, too numerous to list here.



As far as the ATF goes, that practice is a throwback to 20+ years ago when detergent technology was barbaric compared to today. Adding ATF to oil was a trick to free up stuck hydraulic tappets in sludged gasoline engines, because ATF has superb detergent properties. (I've done this myself to attempt a rescue of a neglected engine)



I wouldn't recommend adding ATF to your crankcase at any time. The current CI-4 oils will provide exceptional service when changed at the proper intervals. Don't do extended drain intervals without oil analysis. (analysis very common in fleets)



A little long winded but I hope this helps.

You ever smell marvel mystery. I use this on old engines before an oil change. A cup of diesel works real well too. Sure quites down any lifter noise.

 

[Wheaties]

V,



No that was just the kind of info I was looking for, not long winded at all, in fact, very informative.



BDT,

I always thought Marvel Mystery was kerosene with a little color and fragrance added. I'd guess it was cinnamon. What it really is is a big secret, right?



This is a great thread!

ive owned 5 IsX's. Some have done better than others. I've since started buying Cats. The egr engines wit the vgt turbo are the most responsive engines I've seen in trucks but not very reliable.
