When a Class 8 semi goes down on I-80, the driver faces thousands in downtime costs per day. We repair heavy duty trucks where they sit — engine diagnostics, transmission work, air brakes, electrical systems. Call +1 308-270-3596 and we will roll to your location in Kearney or the I-80 corridor.
Everything needed to keep a Class 8 semi running on the I-80 corridor. Cummins, Detroit, and PACCAR engines. Allison and mechanical transmissions. Full air brake and electrical diagnostics.
Cummins ISX, Detroit DD13/DD15, and PACCAR PX engines. Fuel systems, DEF, air systems, sensor failures — diagnosed and often repaired on-site.
Allison automatic, Fuller manual, and other Class 8 transmissions. Shift faults, pressure issues, solenoid failures. Roadside diagnosis and minor repair.
Compressor faults, brake lines, solenoid valves, and anti-lock modules. Air system problems are safety critical — we treat them that way.
Alternators, starter motors, wiring issues, and control module programming. Many Class 8 electrical faults can be resolved roadside.
U-joints, drive shaft balance, wheel bearing issues, and differential faults. Mobile repair for common axle problems.
Overheating issues, coolant leaks, thermostats, fuel filters, and fuel contamination. Winter diesel issues in Nebraska cold.
A Class 8 semi is not a big pickup truck. Air systems run at 120+ PSI, engines produce 400+ horsepower, and transmission systems handle 1,400+ lb-ft of torque. Electrical systems run 24V and control multiple computers. The Nebraska DOT and CVSA scale officers know what they are checking — if you fail an inspection, you need someone who knows Class 8 construction, not a general mechanic.
On I-80 near Kearney, breakdowns happen during harvest season (grain hauls, cattle trucks, machinery movers) when pressure is highest. A stuck engine or air brake fault can take a truck out of service instantly. We carry the right tools and know how these trucks are built. We are not guessing at your repair.
Call +1 308-270-3596 with the make, engine, and what the truck is doing. We will tell you straight whether it needs a shop or if we can resolve it on the road.
Class 8 refers to semi-trucks over 33,000 lbs GVWR — the standard commercial haulers on I-80. Engine, transmission, air brake, and electrical repairs on these trucks require specialized knowledge and equipment.
Yes. We carry scan tools for Cummins, Detroit Diesel, and PACCAR engines. Roadside diagnosis and repair of fuel systems, sensors, air problems, and DEF systems. Complex engine rebuilds require a shop, but many issues resolve on-site.
Most Class 8 mobile calls run $400–$1,200. Engine work, transmission diagnostics, and brake system repairs run higher. We give you a real quote before we start.
We diagnose transmission issues and handle many common faults on Allison, Fuller, and other auto transmissions. If a rebuild is needed, we discuss options and arrange shop work.
Class 8 trucks run higher pressures, heavier loads, and more complex emission systems. Air brakes, multi-axle drivetrain geometry, and electronic controls require specialized tools and experience.
24/7 mobile repair for Cummins, Detroit, and PACCAR engines on I-80.
