Marine generators are continuously exposed to varying loads, operating temperatures and demanding engine-room conditions. Over time, internal wear can affect compression, fuel consumption, lubrication pressure, cooling performance and electrical output. Our Marine Generator Overhaul in Lome service provides comprehensive inspection, dismantling, reconditioning and testing for auxiliary and emergency generator sets onboard ships.

A generator overhaul goes beyond routine servicing. The engine is systematically dismantled so that critical components can be measured and assessed against the manufacturer's specified limits. Depending on the condition found during inspection, worn components can be replaced or reconditioned before the generator is rebuilt and tested.

COMPLETE DIESEL GENERATOR OVERHAUL

The overhaul scope can include cylinder heads, pistons, piston rings, cylinder liners, connecting rods, crankshaft bearings and valve components. Components are inspected for wear, scoring, cracking, corrosion and abnormal operating patterns.

Measurements such as cylinder liner wear, bearing clearances and component dimensions help establish whether parts remain within acceptable limits. This condition-based approach allows repair work to be based on actual component condition rather than replacing every part unnecessarily.

CYLINDER HEAD, PISTON AND LINER SERVICE

Cylinder heads are inspected for valve condition, valve seats, springs, guides and signs of combustion-related damage. Where required, valves and associated components can be reconditioned or replaced.

Pistons and rings are examined for wear, carbon deposits and damage. Cylinder liners are checked for wear patterns, surface condition and dimensional changes. Correct piston-to-liner clearances are important for compression, lubrication and long-term engine reliability.

BEARINGS AND CRANKSHAFT INSPECTION

Main and connecting rod bearings are examined for abnormal wear, overheating and signs of inadequate lubrication. Bearing clearances can be measured during reassembly.

The crankshaft journals are inspected for scoring, wear and surface damage. Where required, additional dimensional checks can determine whether machining or further corrective work is necessary.

Correct alignment and assembly of the rotating components are essential for reducing vibration and preventing premature bearing failure.

FUEL, COOLING AND LUBRICATION SYSTEMS

Fuel injectors and fuel pumps can be serviced and tested as part of the overhaul. Poor injection performance can contribute to uneven combustion, excessive exhaust temperatures and increased fuel consumption.

Cooling pumps, thermostatic components, heat exchangers and associated piping are inspected when cooling performance is a concern. The lubrication system is also checked, including oil pumps, filters, coolers and pressure-related components.

Turbocharger condition can be assessed for deposits, bearing wear, rotor condition and abnormal operating clearances.

ALTERNATOR AND PERFORMANCE TESTING

A complete generator overhaul also requires attention to the electrical generating section. The alternator, insulation condition, terminals, excitation system and voltage regulation can be checked following mechanical work.

After reassembly, the generator is started and operating parameters are monitored. Where vessel conditions permit, load testing can be performed to evaluate voltage stability, frequency, temperature, vibration and load response.

For a ship calling at Lome, overhaul work can be planned around the vessel's port schedule and available working time. Our Marine Generator Overhaul in Lome service is suitable for planned major maintenance as well as generators showing signs of serious internal wear.

Whether the ship requires a complete overhaul, top-end overhaul or condition-based component renewal, detailed inspection and testing can establish the required scope and help return the generator to dependable service.
