CNG & LNG Heavy-Duty Engine 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.
The work
Natural-gas work we handle
Natural gas is where Los Angeles fleets have been pushed hardest — refuse fleets on municipal contracts, transit and school buses, and heavy-duty municipal vehicles. The trucks exist in large numbers. The people who will service them do not, which is why a CNG unit with a fault so often ends up parked waiting for a dealer appointment while the route it was covering gets absorbed by everything else in the yard.
We service Cummins natural-gas platforms with the same OEM diagnostic approach we bring to diesel. The fuel is different, the ignition and fuel-metering strategy is different, the safety procedure around the fuel system is different — the discipline of diagnosing before replacing is identical.
- Cummins CNG and LNG platform diagnostics
- Ignition system — coils, plugs and misfire diagnosis
- Fuel-metering, regulator and pressure faults
- Engine control and sensor faults
- Cooling, charge-air and boost-side work
- Scheduled maintenance intervals specific to gas platforms
- Emissions and derate diagnosis on gas engines
When to call
Fleets we most often do this work for
- Refuse fleets running municipal collection routes
- Transit and school bus operators
- Municipal heavy-duty vehicle fleets
- Any operator told their only option is the dealer
Coverage
Engines and makes
Cummins and Detroit Diesel, including Cummins LNG and CNG alternative-fuel systems, across Freightliner, International, Isuzu, Hino, Autocar.
Natural-gas platforms have their own maintenance rhythm — plugs and ignition components in particular do not follow a diesel interval. A PM program scoped to the platform rather than a generic chart is usually where the savings start.

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.

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 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.
