DIESEL GENERATOR OVERHAUL

WELCOME TO SEAFIX – MARINE REPAIR SERVICES IN VIET NAM!

* A generator engine overhaul is a comprehensive service that restores the generator to a like-new condition. It involves cleaning, inspecting, and replacing worn or damaged components, extending the generator's lifespan and improving efficiency. Overhauls can range from minor maintenance to complete disassembly and reassembly, depending on the extent of the issue.

Basic comments of diesel generator overhaul:

- Repair or replace crankshaft, connecting rod, cylinder liner, valve seat and valve guide.

- Repair eccentric bearing.

- Replace the plunger pair, oil delivery valve pair and needle valve pair.

- Repair and welding of oil pipe and joint.

- Repair and replace water pump and governor, and remove water jacket scale.

- Check, repair and adjust the circuit, instrument, charging generator and starting motor in the power supply system.

- Install, monitor, test, adjust each system and load test.

* When overhaul diesel engine, generally according to specified working hours data and technical situation. Different overhaul working hours for different type of diesel engine. For example, due to improper use and maintenance or poor working conditions of diesel engine (dusty, often working under overload conditions, etc.), it may not be able to continue to use before the working hours are reached.

* Therefore, in determining the overhaul of internal combustion engine, in addition to the working hours, it is also necessary to determine the following overhaul conditions.

- The internal combustion engine can’t work well (the speed drops greatly after loading, and the sound suddenly changes), and the exhaust emits black smoke.

- It is difficult to start the internal combustion engine at normal temperature. After heating, the crankshaft bearing, connecting rod bearing and piston pin have knocking sound.

- When the temperature is normal, the cylinder pressure can’t reach 70% of the standard pressure.

- Significant increase in fuel and oil consumption.

- Loss of roundness of cylinders, shape, clearance between piston and cylinder, the roundness of the connecting rod journal exceeds the specified limit.

When overhauling diesel engine, we should repair main parts. The whole engine is divided into assembly and parts, and inspected and classified. In addition, it has more technical conditions for repair, so that it can be thoroughly inspected, repaired and assembled.

The main contents of the overhaul are as follows:

1. Disassembly and cleaning: The engine is taken apart, and all components are thoroughly cleaned.
2. Inspection and testing: Each part is inspected for wear, damaged, and proper functioning.
3. Repair or replacement: Worn or damaged components are repaired or replaced.
4. Reassembly: The engine is reassembled, ensuring proper alignment and torque specifications.

Benefits of overhauling:

- Extended lifespan: Overhauling can significantly extend the life of the generator.

- Improved efficiency: By restoring or replacing worn components, the generator can operate more efficiently, potentially reducing fuel consumption.

- Restored performance: Overhauling ensures the generator delivers optimal performance and reliability.

When to consider an overhaul:

- Scheduled maintenance: Generator should undergo regular maintenance, including inspections and overhauls, according to the manufacturer’s recommendations.

- Performance issues: If the generator is experiencing performance problems, such as low power output, excessive fuel consumption, or difficulty starting, an overhaul may be necessary.

- Age of the generator: Older generators may benefit from an overhaul to ensure they continue to operate reliably.
