FINALLY fired this guy on April 1st. He was doing whatever he wanted. Jerry rigging things. Sending trucks to the tire shop for a single tire when the tire could easily have been repaired.
Replacing brake pads on one wheel instead of the whole axle. Not knowing how to properly diagnosis diesel DPF and DEF issues, I have diesels going into re-gen mode 2-3 times a week and drinking DEF like it’s free.
On one of my diesel MT55’s he replaced the ignition switch three times because the truck would just shut off at random. I had a actual mechanic scan the truck with a proper scan tool and turns out the coolant temp sensor was bad. $35 part was sending a over heat signal to the ECU which was shutting the truck down in self protect mode. The temp gauge and ECU use separate sensors so the needle on the dash never gave any indication to a problem with the sensor.
The mechanic we are now using is a mobil mechanic, he only comes to our building once a week so I am still trying to find a local replacement.
In the mean time I am doing the PM’s on my trucks.
Here is a prime example of the kind of work the old mechanic did, or rather, didn’t do.
Factory installed oil filter. You can’t buy these oil filters aftermarket. Motorcraft you can, but not FoMoCo (Ford Motor Company) oil filters.
Not a single drop of grease anywhere on this truck. Steering drag link.
King pin’s.
This truck was brand new in October. I personally drove it from the dealer to our building. I was the first to drive it. And the first to change the oil. The oil smelled like roofing tar. It took almost a full tube of grease to grease it too.
I also changed the oil on two other vans, one had 30k on it’s last oil change, the other was more recent.
My job is more difficult as of right now until I am finished with triage on the fleet, then I can go back and tackle the next set of wounds.
The day’s I go down there are long, I leave home at 5am and do not return back home until around 8pm and drive 250-300 miles on those days.
It is worth it though. In the long run it is going to save our company money.
