We Bring the Shop to Your Yard

A truck sitting in a shop queue is a truck not earning. Our mobile units work on your property — yard, lot or terminal — and the expertise, knowledge and tooling to tackle almost any job on site.

What rolls into your yard

On-Site Mobile Diesel Repair

Qualified technicians and tooling to tackle almost any job in your yard, so the truck never leaves your property.

Advanced Electronic Diagnostics

OEM software diagnostics for Cummins and Detroit Diesel — including Cummins LNG/CNG — precise fault-code and ECM work that cuts guess-and-check downtime.

Custom Fleet PM Schedules

Tiered PM programs — routine checks, advanced diagnostics and DOT inspections — built around how your trucks are actually worked.

On-site diagnostics

OEM-certified diagnostics — Cummins, Detroit Diesel & alternative fuels

Our technicians are factory-trained through seventeen years at Freightliner and International dealerships, running OEM-level diagnostics on Cummins and Detroit Diesel engines — including Cummins LNG/CNG systems — across Freightliner, International, Isuzu, Hino and Autocar trucks. All of it happens where the truck is parked.

Diagnosis where the truck sits
We pull and interpret fault codes with OEM software in your yard, so the repair starts from the actual cause instead of a parts-swap guess.
The unit never leaves your property
No shuttle driver, no shop queue, no second trip to collect it. The truck is back in service from the same spot it was parked.

On-site capability

Heavy axle & wheel-end tooling

Fully equipped mobile rigs carry the heavy tooling needed for axle, wheel-end and hub repair on Class 5–8 trucks and trailers — the work most people assume has to go into a shop.

Air brake & DOT defect correction

An out-of-service brake defect takes a unit off the board until it is signed off. We carry air brake components and the tooling to correct the defect in your yard, so the truck is back in the rotation rather than waiting on a shop slot.

Not what we do

We are not a roadside assistance or towing service. We do not take breakdown calls on the freeway shoulder, and we do not tow. Our work happens on your property, where there is space to do it properly and safely.

Engine-out work and major drivetrain teardown need a shop. Everything short of that we do on site.

Straight answers

On-site repair questions we get every day

Do you come to our yard, or do we bring the truck to you?

We come to you. Our mobile units work at your yard, lot or terminal, which means the unit never leaves your property and nobody spends half a day shuttling a truck to a shop and back. We do not take roadside or breakdown calls on the freeway.

Can a Class 8 truck really be repaired on site?

Most of it, yes. Our units carry OEM diagnostic software, air brake and wheel-end tooling, DPF regeneration equipment and the heavy jacks a Class 8 tractor needs. The work that genuinely needs a shop is engine-out and major drivetrain teardown; everything short of that we do at your yard.

What should I tell dispatch when I call?

Five things get you a faster fix: the yard address and how to get through the gate, the unit number, the truck make and engine, what it is doing or refusing to do, and any fault codes on the dash. Tell us where the unit is parked and whether there is room to work around it.

Do you answer at night and on weekends?

Yes. We schedule around your operation, nights and weekends included. That suits on-site work better than shop hours do, because the best time to service a truck is usually the window when it is parked in your yard rather than out earning.

Which engines and truck makes do you work on?

We are factory-trained on Cummins and Detroit Diesel engines, including Cummins LNG and CNG alternative-fuel systems. On the chassis side we work on Freightliner, International, Isuzu, Hino and Autocar — the makes our technicians spent seventeen years servicing inside OEM dealerships.
