So I am reading in my "Modern Diesel" book for school (I am in Heavy Duty Diesel - truck tech) and they mention that the 7.3 is a Navistar creation and not International. Is Navistar a branch of International or what? or ar they completely different makers?

 

International is a brand of Navistar as is Maxxforce engines, IC bus, and Workhorse custom chassis. At one time, they called themselves International Truck and Engine Company. They've since dropped that name. Not sure what they called themselves during the development of the 7.3L.

 

"Navistar International Corporation (NYSE: NAV) is a holding company whose subsidiaries and affiliates produce International® brand commercial and military trucks, MaxxForce™ brand diesel engines, IC brand school and commercial buses, and Workhorse® brand chassis for motor homes and step vans. It also is a private-label designer and manufacturer of diesel engines for the pickup truck, van and SUV markets. The company also provides truck and diesel engine parts and service."

 

Oooo, so International is the branch off. I just thought it was the other way around. They revived themselves after they created the pile of scrap iron 5.7 Chebby diesel which was a dumb attempt in the first place.

 

The 5.7 liter Chevy diesel was a General Motors creation.
International should not get blamed for that one.

 

good book i just got finished studying out of that one
what school do you go to?

 

Yeah, it is good to read even though its almost 13 years old. But it still is close to what the trucking industry has now. But it needs a overhaul for the newer engine electronics thats out there now. I go to Dakota County Technical College in Rosemount Minnesota and I am in 2nd year, you?

 

i go to great basion college in elko nevada
i am getting my A.S. is diesel techin 46 weeks
and i have two years at area technical trade center in las vegas i also studied diesel tech. so all together im going to be in in 3 years
and im only 19

 

Kool, I am just doing the diploma program here. I already have my 2 yr diploma in Automotive tech and recently having a birthday im 23. I never did the secondary stuff in highschool I just read and did whatever besides talking to my cousin about restoration stuff. Are you guys going through the Bennet Heavy Duty truck systems 4th edition then? or are you doing light & medium duty only? Yesterday we went on a field trip to a rebuilder here called CATCO in Minnesota. I saw a Mack triple countershaft manual transmission for the first time, talk about massive lol. Twin countershafts are a pain already. But Right now my partner and I are wrenching on a 3406E Caterpillar. Its fun, heavy stuff but fun.

 

Yeah those cats are big and heavy. The first inframe I did was on a 3406, the truck was stuck in the corner of a shop and we had to pull the head of by hand. It was 3 of us and 2 ended up on the floor. It's funny to look back and laugh but we did get scared when it happened. Have fun at school.

 

i have done the 3406 thats a fun engine
i just got done building a dt466e and put it on the dyno
it ran 230 hp and 754 ftlbs of torque pulled way over rated specs
thanks to a new turbohousing and bigger injectors out of a dt530e
i love going to school so i think when i graduate from here i might look into wyotech or uti because i want to know everything there is to know.
does your school do Skills USA or Vica?

 

I've done a few of those 466's and for some odd reason the cam on all of them has been worn down. I'm not sure what it is but I think it's from idling them to much.

 

A 3406E Caterpillar? That's really heavy! And a tough one too. so how's the wrenching now?

 

Their all heavy by what most people consider, if your looking at my avatar that's a detroit series 60 in the bed of my truck. My truck was practically sitting on the bump stops. Didn't give me to much confidence on the freeway.

 

Yeah my school does the Skills USA stuff. When I was in the auto program my buddies wanted me to do that but I didnt. Ya know this week I found that the school I am going to is replacing the "Modern Diesel" book we have been using after I graduate, DAMNIT!! lol My suggestion, if you want to learn everything there is and retain it, that won't happen because the brain can only handle so much. Most of retaining info amounts to about 10% that is taught and the other 90% is just knowing where to find it. I have heard plus' & minus' of Wyotech & UTI. I think they just get you into the company's door easier. If I were you I would learn another field for something to fall back onto if needed. But The heavy diesel will be around a long time. especially in trains. But just because the "BIG" schools seem so great alot of the time they don't teach ya much (depending on who you are). Example ASEP for GM, they dont let you work on old, rusty, dirty stuff. you mainly do warranty. Now if you were to take a general automotive diploma/degree whichever. You will be working on all makes, rusty, dirty, and learn how to break loose, fix, and diagnose problems that are ocurring because of the worn out parts. That is where you get your knowledge.I don't know if I am going to do the Diesel competition at the Skills comp in the spring. I am not a person to work the best I can under pressure on something I need to be precise on. But if I feel that I am comfortable enough I will try. And if you noticed on your 3406E Cat kept the old in-block cam area the same, just moving the cam to the cylinder head. Are you strictly Diesel driven?? or are you into automotive also?
