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.
We explored key components such as the torque converter, planetary gear sets, hydraulic control system, clutch packs, and output shafts, with particular attention given to the hydraulic valve body, which governs gear shifting based on sensor input. Additionally, we highlighted the significance of fluid quality and the necessary calibration procedures following maintenance. Through interactive Q&A sessions and cross-sectional diagrams, we aimed to solidify the technicians' understanding, ensuring they could identify major components, articulate the gear shift process, and grasp the fundamentals of transmission troubleshooting by the conclusion of the training.
Day 8 – Dismantle and Assemble Training of BS305/306 Transmission
On the eighth day of our technical training, our team concentrated on the disassembly and reassembly of the BS305/306 transmission. The session commenced with a safety briefing that highlighted the necessity of using appropriate lifting tools, personal protective equipment (PPE), and maintaining cleanliness when handling internal components. We then engaged in a meticulous step-by-step disassembly, identifying key parts such as the torque converter, planetary gear sets, clutches, valves, and shafts.
Technicians were encouraged to actively participate by inspecting worn components, assessing tolerances, and recognizing signs of overheating or mechanical wear. Following a thorough inspection and cleaning of all parts, we demonstrated the assembly process, stressing the importance of proper alignment, torque specifications, and sealing techniques to prevent leaks and ensure optimal performance. Throughout the session, we reinforced the significance of adhering to the service manual and utilizing the correct tools. This hands-on experience not only bolstered the technicians' confidence but also enhanced their precision in both disassembly and assembly tasks. The day concluded with a Q&A session to address common field challenges, solidifying the learning outcomes and contributing to the team's overall technical proficiency.
Day 9 – Certificate Awarding to the Technicians
On Day 9, the training program wrapped up with a significant certificate awarding ceremony for the participating technicians. After several days filled with hands-on learning, technical discussions, and practical demonstrations, the technicians were honored for their commitment and successful completion of the program.
