How Crosspoint’s Diesel Engine Repair Restored Fleet Activity
When a Yanmar-powered jetter pump was accidentally filled with gasoline instead of diesel fuel, the engine shut down and the equipment was removed from the rental company’s active fleet. Every day the unit remained unavailable, represented lost rental revenue and reduced fleet utilization. Crosspoint diagnosed the damage, restored the fuel system, verified engine performance under load, and provided preventive guidance to help reduce the risk of future fuel contamination.
The Challenge:
Returning Revenue-Generating Equipment to Service
For equipment rental companies, every machine in the fleet is expected to be available when customers need it. When critical equipment goes out of service unexpectedly, the impact extends beyond the repair itself. Downtime reduces rental availability, delays customer projects, and limits revenue generation.
Our client, a nationally recognized equipment rental company, encountered this challenge after gasoline was mistakenly introduced into the fuel system of a Yanmar-powered jetter pump. Because diesel engines rely on the lubricating properties of diesel fuel, gasoline contamination can damage fuel system components and create significant reliability concerns if not properly addressed.
Rather than attempting a partial repair, the unit required a thorough evaluation to determine which components could be safely reused and which required replacement before the equipment could return to the rental fleet.
Crosspoint’s Approach:
Expert Diagnostics Before Repairs
Crosspoint approached the project by first identifying the full extent of the contamination instead of immediately replacing parts.
Our in-shop technicians completely removed the fuel tank and fuel system for inspection before carefully disassembling affected components. Each part was evaluated to determine whether it could be cleaned and restored or required replacement.
After documenting the findings, Crosspoint prepared a detailed repair estimate and reviewed the recommended repairs with the equipment rental company before work began. This process ensured the customer understood both the scope of the damage and the reasoning behind the proposed solution.
By combining technical diagnostics with clear communication, Crosspoint helped the customer make an informed repair decision while avoiding unnecessary component replacement.
The Solution: Restoring the Engine and Protecting Future Reliability
Once the repair plan was approved, Crosspoint thoroughly cleaned the fuel tank and salvageable fuel system components while replacing those that had been damaged by the gasoline contamination.
After reassembly, technicians performed extensive testing, operating the engine under both unloaded and loaded conditions to verify proper performance before returning the equipment to service.
To reinforce confidence in the repair, the engine was demonstrated in front of the customer, allowing them to see the restored performance firsthand.
The project concluded with a review of the root cause and practical recommendations to help reduce the risk of future fuel contamination. By sharing application-specific insights alongside the repair, Crosspoint helped reinforce long-term equipment reliability and fleet readiness.
The Result: Faster Return to Service and Greater Fleet Confidence
Following repairs, the Yanmar-powered jetter pump was returned to the equipment rental fleet in fully operational condition.
While no specific performance metrics were recorded, the project delivered several meaningful operational benefits:
- Returned a revenue-generating asset to active rental service
- Reduced the risk of additional engine damage caused by contaminated fuel
- Restored confidence through verified engine testing
- Helped fleet personnel better understand how to prevent future fuel contamination
- Demonstrated Crosspoint’s ability to manage complex industrial engine failures from diagnosis through final testing
Rather than simply repairing the equipment, Crosspoint helped ensure the customer understood why the failure occurred and how to reduce the risk of repeat incidents.
