What we do
Heavy-Duty Fleet Repair & Maintenance Services
Full-spectrum heavy-duty diesel services for Class 5–8 fleets — mobile repair, OEM electronic diagnostics, and custom preventative maintenance programs — carried out at your yard, backed by dispatch that works around your yard’s schedule.
The full range
Nine services, one call
Mobile diesel repair, OEM-level diagnostics and custom fleet PM — including LNG/CNG alternative-fuel systems — from a team with thirty years of OEM-dealer experience, performed where your trucks are parked.
Diesel Engine Repair
Cummins and Detroit Diesel engine work carried out at your yard — diagnosed with OEM software before a single part comes off, by technicians who spent seventeen years doing it inside Freightliner and International dealerships.
Read moreElectronic Diagnostics
Reading a code off a generic scanner tells you a circuit is unhappy. OEM-level diagnostics tell you which part is failing and why — and that difference is usually the whole repair bill.
Read moreDPF & Aftertreatment
A truck that regens constantly is not telling you the filter is full. It is telling you something upstream is putting soot into it faster than it should.
Read moreCNG & LNG Service
Very few shops in Los Angeles will touch a natural-gas heavy-duty engine. If you run CNG or LNG and have been told to take it to a dealer, talk to us first.
Read moreClean Truck Check
A Clean Truck Check failure does not just cost a retest. Compliance is tied to DMV registration — an unresolved failure can stop you registering the unit at all.
Read moreBrake, Air & Suspension
An out-of-service brake defect takes a unit off the board until it is corrected. We carry the components and the tooling to correct it in your yard rather than in a shop queue.
Read moreDrivetrain & Transmission
Wheel-end and axle work is the job most people assume has to go into a shop. With the heavy jacks and tooling on board, most of it does not.
Read moreElectrical Systems
Electrical faults are the ones that get parts thrown at them, because the symptom moves and the cause hides. We trace them instead.
Read morePreventative Fleet Maintenance
PM programmes scoped to duty cycle and the DOT/BIT calendar, documented per unit and run at your yard.

Advanced electronic diagnostics
OEM-level diagnostic software for Cummins and Detroit Diesel engines — including Cummins LNG/CNG systems. Reading a code off a generic scanner tells you a circuit is unhappy; OEM diagnostics let us interrogate the ECM, run tests and pinpoint the actual fault.
- Cummins & Detroit Diesel diagnostic software, including LNG/CNG
- Full engine & aftertreatment fault-code scans
- DPF regen & emissions system diagnostics
- ECM reflashes where the platform supports it
Preventative maintenance
Custom fleet PM schedules
Every PM program we build is scoped to your duty cycle and DOT calendar. A standard inspection covers:
- Engine Oil & Filters
- Air Brake System
- Wheel-End & Tire Wear
- Fluid Levels
- Battery & Electrical
- DPF & Emissions
- DOT Inspection Points
Everything but engine-out
More of it happens on site than you would think
Our mobile units carry OEM diagnostic software, air brake and wheel-end tooling, DPF regeneration equipment and the heavy jacks a Class 8 tractor needs — so the jobs most people assume have to go into a shop get finished in your yard instead.
We work Freightliner, International, Isuzu, Hino and Autocar chassis, and Cummins and Detroit Diesel engines including natural-gas platforms used by refuse, municipal and transit fleets.
