Class 8 Diesel Services Built for Port Operations.

Unplanned breakdowns are the enemy of port operations. Our preventive maintenance programs are built around your fleet's specific duty cycles, mileage intervals, and manufacturer specifications. We use OEM-grade fluids, filters, and components to maximize engine longevity and protect your investment.

• Engine oil and filter changes (all major brands)
• Coolant system service and flush
• Fuel filter replacement
• Air filter inspection and replacement
• Lube service — chassis, fifth wheel, and driveline
• Belts, hoses, and clamp inspection
• Fluid level checks and top-offs
• PM documentation for fleet records

Modern Class 8 engines are complex systems. Our technicians are trained on Cummins, Detroit Diesel, PACCAR (MX), Volvo, and Navistar platforms, and we use factory-level diagnostic tools to pinpoint faults fast. We don't guess — we diagnose, document, and repair with precision.

• Electronic fault code diagnostics (all major ECMs)
• Cummins, Detroit, PACCAR MX, Volvo D13/D16, Navistar
• Injector testing and replacement
• Turbocharger inspection and service
• Cylinder head and valve train repair

• Brake system inspection
• Steering and suspension check
• Lighting and electrical inspection
• Tire and wheel inspection
• Coupling devices and fifth wheel
