Comprehensive Mechanical Overhaul & Precision Clearances

Working through major repairs on large-bore marine diesels demands exact technical data. This Baudouin M26.2 Series Engines Repair Manual details internal specifications for the 150 mm bore by 150 mm stroke engines. Inside, technicians will find critical wear limits and rebuild clearances covering:

• Cylinder Block & Liners: Calculation methods for cylinder head gasket thickness selection (Z = X + Y + 0.08 mm for 6M26.2; stepped selection 2.0 mm to 2.50 mm based on liner protrusion D for 8M26.2 and 12M26.2). Includes precise on-engine cylinder block counterbore rectification using specialized cutter tool 15 59 950 0D.
• Crankshaft & Bearings: Journal wear limits, nominal and undersize repair dimensions (1st repair -0.5 mm, 2nd repair -1.0 mm), crankcase wall spreader tool requirements (13599730Q) to prevent main bearing web distortion, and axial end-float settings.
• Pistons & Mobile Couplings: Full dimensional checks for both 4-ring pistons (Series 2000) and 3-ring pistons (Series 5000 and 262-000). Covers ring groove clearances, ring end-gap measurements in a 150 mm gauge, con rod weight classification sorting (classes A through H), and connecting rod bolt reuse criteria (maximum 3 punch marks or 16,000 service hours).
• Valves & Cylinder Heads: Individual 4-valve cylinder heads with single-unit architecture. Detailed steps cover valve seat removal via welded valve technique, cryogenic shrinking in liquid nitrogen, guide driving depths, valve head recession tolerances, and copper injector sleeve replacement and roller-crimping.

Fuel Injection, Governing & Marine Auxiliaries

Fuel delivery precision is paramount on Baudouin commercial propulsion and auxiliary drives. This service manual provides complete procedures for pinning the flywheel to engine reference cylinders (ERC #6 on 6M26.2, ERC #8 on 8M26.2, and ERC #12 on 12M26.2) and synchronizing multi-plunger inline injection pumps. Technicians are guided through using start-of-delivery electronic signal boxes (15058340L), magnetic angle protractors on vibration dampers, and graduated adjusting drums. Coverage extends to injector testing benches, calibrating pop pressures (250 to 260 bar), testing nozzle chatter, and setting electronic actuators for Woodward speed controls and Heinzmann StG 6 governors.
