Running Hour Based Overhaul

At YAF Engineering, we offer complete engine rebuilding services for both marine and stationary diesel engines. Our procedures follow OEM specifications and include a full teardown, inspection, and reassembly using new or reconditioned components to ensure maximum performance and reliability.

Our standard full engine rebuilding process includes:

  • Complete disassembly of all engine components followed by thorough cleaning to remove carbon, sludge, and deposits

  • Detailed inspection of the crankcase, crankshaft, and all major structural elements

  • Rebuilding the engine with new seals, bearings, liners, pistons, connecting rods, and cylinder heads, ensuring full dimensional and material integrity

  • Renewal of the vibration damper to maintain proper harmonic balance

  • Overhaul of auxiliary systems, including oil and water pumps and heat exchangers/coolers, to restore full operational efficiency

  • Application of a fresh protective coating to the engine block for corrosion resistance and a clean, professional finish

Each rebuilt engine is tested, documented, and delivered in ready-to-run condition, with complete service records and quality assurance in line with international marine and industrial standards.
