Services

Repair, CAT ECM service and custom engineering

Hands-on work on military trucks, focused on the platforms we know best. Every job starts with a scope review, so the quote reflects the actual truck.

Repair and service

Repair for 1990-and-newer military trucks

We also accept the M939A2 series. Depth of experience differs by platform, and we will tell you where your truck falls.

Platforms

MTVR
Primary specialty and our preferred work.
LVSR
Specialty platform for repair, electronics and parts.
MTV and LMTV
Accepted after we review the specific truck and job.
M939A2 series
Accepted. The one exception to our 1990-and-newer rule.

Work we do

  • Preventive maintenance and inspection
  • Electrical diagnostics and troubleshooting
  • Engines, transmissions, transfer cases and axles
  • Brakes, suspension and steering
  • Cooling, fuel and air systems
  • CTIS and wheel ends
  • Custom parts and modifications

What we need to quote

  • Model, variant, year and serial number or VIN
  • Symptoms, fault codes and recent repairs
  • Photos, data-plate information and part numbers
  • Where the truck is, and whether it can be transported
  • Your timeline and the outcome you want

Acceptance depends on the vehicle, its condition, parts availability and the shop schedule. We confirm scope before you transport a truck.

CAT ECM

Caterpillar ECM programming and rebuild

Two engine families today. Programming covers configuration changes where the ECM, engine and application support them.

Not every ECM is recoverable. We review the part number, serial number and condition before quoting, and before you ship anything.

Send us

  • ECM part number and serial number
  • Engine serial number, if you have it
  • Existing calibration or configuration details, if known
  • Symptoms, fault codes and whether the ECM communicates
  • Any physical, moisture, power or connector damage
  • The result you want: programming, configuration or data transfer, diagnosis, or rebuild

Engineering and fabrication

Replacement parts when the originals are gone

Out of production, overpriced or poorly designed: we develop a replacement that fits and does the job.

How we develop a part

  1. Define the function and the failure

    What the part does, what broke, and why.

  2. Capture dimensions and specifications

    From the original part, drawings or measurements.

  3. Set load and safety requirements

    Safety-critical parts get a specification check.

  4. Choose material and process

    The method that suits the part and the quantity.

  5. Prototype, inspect and fit-test

    On a truck, before anything is produced.

  6. Release for production

    Revisions are controlled, quantities authorized.

Methods

Depending on the part, that can mean CNC machining, laser cutting and welding, 3D printing, or adapting a commercial component. Electrical, hydraulic, pneumatic, cab and mounting solutions are all in scope.

We confirm feasibility, cost and lead time only after a technical review of the part and the job it has to do. Customer drawings and files stay confidential.

Discuss a part

  • Side view of an MTVR cab fitted with the aluminum hard door kit

  • Defroster vent insert next to its housing ring
    Defroster vent insertsMade in the USA with tighter tolerances than the factory part, so the vents stay where you set them.
  • Mounting bracket modeled in CAD on a computer screen

We inspect and service braking, suspension, and steering systems to maintain safe handling and stopping performance under load. All work is completed with an understanding of the unique demands placed on military vehicles.

Cooling, Fuel & Air Systems

We service cooling, fuel, and intake systems to prevent overheating, fuel delivery issues, and power loss. Proper system operation is critical for both daily use and extended operations.

CTIS & Wheel End Service

We diagnose and repair Central Tire Inflation Systems (CTIS), hubs, seals, and wheel-end components common to military platforms. Our goal is to restore proper operation while reducing repeat failures.

Horsepower Upgrades

We offer horsepower and performance upgrades tailored to military truck powertrains to improve drivability, load handling, and overall efficiency. All upgrades are designed with reliability in mind, balancing increased output with safe operating limits for long-term use.

Custom Parts

We design and fabricate custom parts and solutions for military trucks when off-the-shelf components are unavailable or inadequate. Our custom work focuses on durability, proper fitment, and real-world performance in demanding operating conditions.
