Diesel Engine In Frame MaxxForce DT

If you told me we would be rebuilding one of our MaxxForce engines in six years I would have laughed and then went into total denial.

Touring a Tire Retread Plant

This was my first experience getting a tour through a tire retread plant. Kal Tire supplies our recaps for our bus fleet and they asked us to come down and see where it all happens. It’s a long process from start to finish and I can see why they do not want to find a… Continue reading Touring a Tire Retread Plant

MaxxForce DT Diesel Engine EGR Cooler Failure

As you can see the EGR cooler from this Navistar DT MaxxForce engine is massive and it weighs I’m guessing around 50 pounds. Why is it so large?

School Bus Fleet GPS Telematics

Years ago… 20 to be exact when I started working for this school bus fleet we relied on land lines and 2 way radios to get a report on break downs.
