Four-stroke medium-speed diesel engines are widely used as prime movers and for power generation across both marine and land-based applications. At YAF Engineering, our technicians and engineers execute numerous four-stroke engine overhauls every year — ranging from routine maintenance tasks to complete crankshaft and engine block replacements.
Each overhaul project is approached individually, based on engine condition and customer requirements, or as part of a planned engine maintenance strategy tailored to ensure operational efficiency and reliability.
Our engineers are equipped to perform comprehensive diesel engine services on medium-speed four-stroke engines, including:
To reduce onboard downtime, mitigate repair uncertainty, and improve cost-efficiency, YAF Engineering has implemented an engine component exchange program. This concept allows clients to replace critical components with fully serviced parts from our in-house stock — minimizing waiting time and eliminating the risks of on-board emergency repairs.
We maintain a ready-to-ship inventory of key components for common diesel generator engine types, including:
All exchange parts are fitted with new consumables, inspected, tested, and certified by our workshop technicians — ensuring full reliability and immediate usability for any diesel engine overhaul project.
YAF Engineering’s four-stroke diesel engine services are designed to deliver performance, reliability, and peace of mind — whether for scheduled drydock overhauls or urgent powerplant support.
