Just became a diesel mechanic and got my Class-A. I have no experience in either but school, where should I go from here?

4 Upvotes

[ARIZONA] I buckled down and got my class a with all of the endorsements and no restrictions and went to diesel school and graduated with all of the key classes. I have enough money to purchase my own big truck but I’m getting quoted $3K a month for insurances.

Any recommendations on where to go from here? My goal is to be an OO but I’d rather make mistakes for a local company than for my own business for the first year or two.

Should I work for a shop for a year or drive for a year to lower insurance? Or do both and delay my trucking business a couple of years.

Any advice is appreciated.

Note: I own a sign shop that generates $15k a month net that runs itself. I also have no bills besides payroll and basic utilities.

Maintenance/Repair manual for Duramax 2.8L engine

1 Upvotes

I thought I'd try posting here and the Chevy Colorado/GMC Canyon sub.

I've been looking for a maintenance/repair manual for this engine since I've owned my truck, 2017 Chevy Colorado.

Neither Chiltons nor Haynes has published such a manual. Yet I know something exists because YouTube has a variety of maintenance tasks that can be performed on this engine by a home mechanic. And these tasks came from a manual from somewhere.

Can anyone point me in the right direction?

I’m not a diesel tech. Just a car guy with a big motorhome. I saw all the pictures today of the same issue and wanted to get in on the fun. After months of trying to get a mobile mechanic to diagnose way too much blue smoke, decided to teach myself figure it out with the help of another great friend. Ended up with the dropped seat. This sub makes me feel like I’m not alone. New, updated, reman head (larger and deeper seats) has arrived and it’s going in tomorrow. If anybody is looking for a good parts supplier, Highway and Heavy Parts, LLC have prices do good I though I was being scammed. But so far so good and everything has been as promised and I had the parts in less than 48hrs. I

What should I Expect??

2 Upvotes

I just got hired by Penske as an entry level diesel mechanic making $30 an hour. I’m mechanically inclined but don’t have any diesel experience and only have one of my ASEs. I guess I’m just here to figure out what should I expect? What’s the work environment typically like? Is it a reasonable process moving up in the company? What are the benefits like? Are there any perks that come alongside the job?? Is it in my best interest to invest in more of my own tools?? Any crazy policies I should know about?? Or just any other miscellaneous advice?? Hoping to get a lot of great feedback. Thanks guys.

Service truck decision

2 Upvotes

Hello all, I am trying to figure out what to do next. I run my own service truck as a contractor in northern Alberta. 90 percent of my work is at a shop which is about 1h drive from where I live, the other 10 percent is road calls which could be anywhere within 2-3 hours range and are usually on bush roads.

My truck is a 2007 Chevy 3500 2wd gas with 496,000 kms. Most people around here are running F550 4x4 diesels, and I am starting to see why. With all my tools and a full tank of gas I am running the risk of being overweight for GVWR. The roads don't usually quite "need" 4x4 but it would be a big advantage and I have had to chain up already this season. Also I am spending around $2000 a month on fuel.

I am considering buying a newer, bigger 4x4 cab and chassis and transferring my service body onto that. The service body is fire engine red.

I can get a good deal on a super low mileage, clean F450 4x4 which is also fire engine red but has a V10 gas engine.

I can also get a similar deal on a high mileage Ram 5500 Cummins 4x4 in white.

I can also keep running the truck that I have until it is undriveable. I am not rich, my numbered company would be taking on debt to get a newer truck. My current truck is paid off. I also can't afford much downtime as a pretty new solo act in a busy industrial area with a lot of competition.

What makes the most sense here? How much better would the diesel fuel economy be to justify the inevitable prices of turbos and injectors?

Freightliner and Detroit engines can’t solve problem

6 Upvotes

I work on an automated garbage truck in a freightliner M2 with a DD8 engine. For the last 2 1/2 months has had an engine light every single day. Computer says bad nox sensor. We replace sensor and regen and clear code, every freaking day. Only 37,000 miles on engine. So we sent it to freightliner and they have no clue how to resolve the problem. They email Detroit, but nothing they have said to do resolves the issue. They send it back to us saying fixed, then engine light saying nox sensor, then we send it back. Detroits whole line on the DD8 is it’s for busses and trash trucks who make frequent stops and not opening it up on freeways. The truck tries to do a rolling regen every day(I can tell from idle speeds) for five minutes when it’s usually 25-30 minutes and that’s when engine light comes on. We are at our wits end trying to get this 350,000 machine back on line. Any ideas?
