Day 5 : Actual trouble shooting Cummins 6.7/7 engine
On the fifth day of the Cummins 6.7/7 engine training, the emphasis transitioned from theoretical concepts to practical application as technicians participated in hands-on troubleshooting exercises. The day commenced with a brief overview of common engine fault codes and the utilization of diagnostic tools, including the INSITE software. Participants were organized into small groups, each assigned real engine units with simulated faults for direct assessment. They tackled issues such as sensor failures, fuel system blockages, EGR malfunctions, and low boost pressure, systematically applying the troubleshooting procedures learned in earlier sessions.
Safety practices, accurate interpretation of diagnostic data, and the
correct use of multi meters and scan tools were highlighted throughout
the exercises. One group successfully identified a malfunctioning
turbocharger actuator that was affecting engine performance, while
another resolved a crankshaft position sensor error through effective
testing and replacement.
Instructors provided ongoing support, correcting any improper techniques and fostering critical thinking. By the end of the day, technicians emerged with increased confidence in diagnosing and repairing real-world engine problems, reinforcing their understanding of the Cummins 6.7/7 systems and the significance of methodical diagnostics for ensuring engine reliability and performance.
Day 6: Theoretical and Actual Troubleshooting of the Hydraulic System
On the sixth day of training, the emphasis was placed on both the theoretical aspects and practical troubleshooting of hydraulic systems. The session commenced with an in-depth exploration of essential components such as pumps, control valves, cylinders, hoses, and filters, highlighting the impact of hydraulic fluid pressure and flow on machine performance. Participants learned to recognize common issues like slow operation, leaks, overheating, and erratic movements.
Technicians were instructed on reading hydraulic schematics and utilizing tools like pressure gauges, flow meters, and infrared thermometers for accurate fault diagnosis, while also reviewing safety protocols for working with pressurized systems. During the hands-on segment, technicians engaged in a step-by-step diagnosis of simulated faults, addressing problems like stuck valves, air in the system, and clogged filters. This practical experience allowed them to apply real-time troubleshooting techniques on actual machines, enhancing their skills in isolating issues, confirming root causes, and replacing defective components.
Day 7 Theoretical Training – BS305/306 Transmission
On the seventh day of our theoretical training with the technicians, we delved into the operational principles and internal components of the BS305/306 transmission system. The session commenced with an in-depth discussion on the transmission's critical function in power delivery, emphasizing its role in transferring engine output to the drive train while maintaining precise control over speed and torque.
