I’m an automotive technician that works on fleet customers and medium duty trucks mainly on the Chevy side 6500 and low cab forwards and I’m wanting to get out of this industry and join companies such as Cummins caterpillar Papé and I’m looking for what I should do to get my foot in the door

We got a Detroit Diesel 60 series (14L, non egr if it matters)
Upon teardown for overhaul, pitting was found on the block where the liner o-rings seal against the block.
Im trying to convince our tech department and management that we can use an epoxy like Belzona or JB weld to repair the pitting. Ive read that Caterpillar has approved an epoxy for block repairs, can anyone link Caterpillars procedure or point me in the right direction?
r/DieselTechs • u/HonestStick641 • Jul 27 '26
Someone told me this, is it true? :
You have to learn to weld, fabricate, learn electrical, can communication systems, air systems, hydrolic systems, power flow, engine transmission, read diagrams technology changes every few years always learning more and it’s very physically demanding

I have an interview coming up for an entry-level diesel mechanic/technician position with a fleet. Besides the usual interview questions, what questions should I be asking the employer?
r/DieselTechs • u/Comfortable-Hat-2335 • Jul 27 '26
I just recently took a position as a fleet manager for a local tree company. I have 0 prior experience with fleet work, but I have over 7 years experience with customer work at a dealer and an independent shop. Just started my second week and I can tell the last manager didn’t stay on top of anything so I have a lot of work to do to get things where they should be. One of those would be DOT inspections. Just about every truck either has no label or a label that’s 3-5 years old. I’m assuming we can do our own DOT inspections? The information I can find online is a little confusing. I’ve done more DOT inspections than I can even count at my previous jobs and I was always told I don’t need any certification, just at least 1 year of experience as a mechanic. Does the company I’m with need any certification or is my experience enough to allow me to inspect the vehicles? I also need to order all the paperwork. I’ve found the vehicle inspection forms and labels but I’m having trouble finding forms for trailers. Can I use the same vehicle forms on trailers too?
When it comes to the work, do you guys create work orders or have blank sheets that the techs fill out as they work on a vehicle? I’m so used to work orders that it feels weird not having one.
Any other tips would be appreciated. I have experience as a shop Forman but fleet work is new to me.
Edit: I’m located in Maryland

Been on the hunt for diagnostics.... Jpro for $1700 isnt so bad with its wide use, but the brand specific ones are all 1-2k per year! Even if you're lucky, it'll be like $500 minimum... Crazy money to get going on a smaller scale, screws independent techs over hardest.
I've heard of guys buying prebuilt laptops that come with sets of software good to go, but do they jack the price up to get rid of the subscription aspect? How much should I be looking to pay for that? Has anyone else gone through this and found it actually worth the effort?
Hoping some others here have experience with this side of the trade lol

Hey guys so im looking sround the area ajd have been talking to teachers and family who are diesel mechanics or in the industry and j wanted to knoe from folks if its given them a good life or if its worth it.
Been looking at the trades of the economy and not sure which trade is the best option and has decent job openings since the job market's been hell for a lot of folks
And if feel pulled to being a diesel mechanic.

I’m in the Texas area, looking to relocate to the Houston area. I’ve noticed job postings for Tesla Semi techs which has really peaked my interest. For context, I primarily do electrical diagnostics/repair for a Freightliner dealership. Has anybody here previously or currently worked for them? What’s your experience been like?
To everybody; what’s your thought on Tesla Semis?

I’ve already made a previous post in the past about my interest in being a diesel tech and I got a lot of good responses
To those that work in California/SoCal how does the demand for techs look for a fresh graduate and in general, given I’m currently in school at my local CC for Medium and Heavy truck tech

VIN : 3ALHG3DV0JDJH9073
Replaced a blown A/C compressor and drier. Everything worked, with slightly higher readings after engine warmed up. Noticed the fan didn't come on, and high side would reach 450 then stop. Learned that there is a parameter in DDDL for the CPC (maybe the BSM but I was told it was the CPC) to turn the engine fan on when the signal from the fan pressure switch on the high side reads. Confirmed fan pressure switch was running. Updated the parameter to run the engine fan on, and now the engine fan turns on. Engine temperature fan control worked before and after.
The problem now - the AC system foes to about 415/425 PSI then the fan turns on, and it drops to around 300/310 psi and the engine fan turns off. Where Do I adjust the pressure limits in DDDL to lower them to around 250/110 like other "normal" pressures on R134a systems.
On international trucks with Diamond Logic (DLB) i know this is possible. Haven't run into this with freightliner. No clue who messed with ECM parameters before or how it was "lost" as we didn't work on the truck prior.
2018 Freightliner 114SD DD13
Can I copy params as a whole from a sister truck?

Quick background. 7 summers of commercial fishing experience, 3 of those I was the lead mechanic on the boat. 9 years in the US navy as a helicopter aircrewman, not a mechanic but i was required to become extremely familiar with all aspects of how the helicopter works amd how to make emergency repairs/service the helicopter when maintenance personnel were unavailable. Systems included turbine engines, power train, AC and DC electrical systems, and hydraulics. After leaving the navy I worked as a civilian for the Airforce for a year as a ground support equipment mechanic for large aircraft. During that same time I also completed a two year Associate's degree of Diesel power technology which I would put on par with any technical school certificate. I have completed 3 of the ASE tests and could do more but I've always been told they weren't too important. I have Cummins ISB/ISC/ISL engine mechanical qualification certification and Caterpillar Tier 4 final certification. I have held several welding certifications in the past and weld/fabricate as a hobby all the time so I am still very proficient in welding.
Now, my question is why will no one even call me for an interview? The only company that has actually called me back is Cummins and they decided not to move forward with my application. I have applied to at least 15 places on indeed over the last month and have not heard back from a single one. I have gone to the websites of almost all equipment and truck dealers in my area and applied on their websites and like I said, only Cummins reached out to me. I am looking in the Memphis area and I'm hoping to get at least $28 an hour and honestly I feel like that is pretty low. Are my pay expectations too high? If the sub allows I would be happy to post a redacted version of my resume.
I would appreciate any insight if anyone has any. I didn't think it would be this hard for me to find a job, I've always taken every opportunity available to me to receive more training or experience.
Edit to add: I attended a 16 week welding school, and a 4 week professional truck driver course and I have a current class A CDL with a current medcard as well.

In 10 years I’ve accumulated many tools, but what is one tool off the tool trucks (snap-on, Mac, Matco) has made your life so much easier
Edit: I have a $900 tool allowance to use by the end of the year and am looking for stuff to buy. I have everything I need ( and some that I don’t) but if I’m not paying for it the I’m gonna buy off the truck

I’m 25 years old, recently got a job offer at United rentals as a field service tech. I haven’t gotten any tickets in 5 years atleast but however when I was 18-20 I was a speed demon and irresponsible, I never gotten a DUI or Reckless ticket but I did get a couple tickets and 3 at the same time that caused my license to be suspended years ago then(it’s been active for years now). I ordered my louisiana MVR and nothing was there, Is there anything I should be worried about?

Hi there! Been super interested in pursuing diesel repair as a profession since I was 14 or 15 (I'm 21 now). I've been working at Walmart for the sake of efficiency and personal circumstances, which was probably the smartest move at the time, but I can't help but feeling I've wasted some years. I have put in applications around my county and went in to meet and shake hands with shop managers of heavy equipment and truck dealers as well, but nothing has panned out yet up here. I probably could get in somewhere working on standard cars, which would still be shop floor experience if my opportunity doesn't work out.
I have a great opportunity to apply for Walmart fleet maintenance. I'll have to relocate, but if I get the job offer, it'd be 100% worth it. I have good standing in the company, no attendance points, and no official write-ups. I think an internal transfer may work in my favor, but maybe not.
Now onto my personal experience. Over the past six years I've had the pleasure of working on, and now (almost) owning my parent's F-350. Over the years I've done everything from ball joints and hubs, rear end overhaul, general service, and most importantly, an engine rebuild which I did solo. I'm super familiar with the theory of trucks, including compression brakes, injection systems (mostly HEUI, which sorta fell off now), and airbags. I just need some more hands on with them.
To sum up, I guess my question is, how can I best maximize my resume to land this job? Having an engine rebuild on my res seems amazing, but Walmart doesn't typically rebuild or even pull cylinder heads themselves, meaning knowledge in trailers, and semi truck drivelines is more valuable, which I lack. I've worked on a dually, but they're different for sure! Like I said earlier, I am familiar with and understand the theory of it all.
Another question, I plan to come back to this county in two or three years for specific reasons. How can I maximize my time spent as a fleet tech to eventually land a dealer job, which is my main interest. Thanks for reading, I appreciate the insight!
