Welcome

On-Site Heavy Equipment Repairs Across Colorado, Wyoming, and Nebraska

NoCo Diesel Services LLC provides reliable heavy equipment repair for diesel-powered machinery used in construction, agriculture, utilities, and commercial operations. Based in Johnstown, CO, we offer 24/7 mobile equipment service for businesses and job sites throughout Northern Colorado, Southern Wyoming, and Western Nebraska.


Whether your loader is down, your excavator won’t start, or your generator has a fault, we bring dealership-level expertise directly to your location—eliminating the cost and hassle of transporting large equipment off-site.

What Is a Wheel Seal, and Why Does It Matter?

Wheel seals are designed to keep oil or grease inside the hub while preventing dirt and moisture from entering the bearing system. Over time, seals can wear out, become brittle, or shift due to heat, contamination, or excessive movement. Once a seal fails, lubricant escapes and contaminants may enter the hub—leading to bearing failure, brake contamination, and unsafe operating conditions.

Common Heavy Equipment Problems We Fix

Heavy equipment is built to work hard, but it’s also exposed to demanding conditions that accelerate wear and tear. We handle a wide variety of repair needs in the field, including:


  • No-start conditions and hard starts
  • Loss of power or poor engine performance
  • Electrical failures and wiring issues
  • Faulty sensors and dash warnings
  • Fuel system problems (filters, priming, injection)
  • Air intake and turbocharger issues
  • Hydraulic pump or line failures (basic hydraulic support only)
  • Cooling system leaks and overheating
  • Battery, alternator, and charging faults
  • Exhaust and aftertreatment system problems (DPF, SCR, DEF)
  • Preventive maintenance (oil, filters, inspections)


If your equipment is down or showing signs of failure, we can respond quickly and provide expert diagnostics on-site.

Breakdowns don’t wait for business hours. That’s why we offer 24-hour mobile repair for heavy equipment. Whether your loader fails during a concrete pour or your generator won’t start before a weekend job, we’re ready to respond with the right tools and parts to restore functionality. We work in environments where uptime matters:

  • Construction sites

  • Job site trailers and mobile offices

Equipment Diagnostics and Troubleshooting

Heavy diesel equipment often uses advanced electronics and control systems to manage engine performance, emissions, and safety features. We use professional diagnostic tools to perform:

  • ECM code scans and troubleshooting
  • Live data monitoring for sensors and actuators
  • Voltage and continuity testing
  • Component-specific fault isolation
  • Resetting of fault codes after repair
  • DEF and aftertreatment system analysis

We also inspect supporting systems like cooling, intake, and charging systems to ensure proper function and prevent repeat failures.
