Important Notes

• Verify part number 544039001 before ordering
• Confirm compatibility with your specific Husqvarna equipment model, engine model, and production configuration
• The exact crankshaft dimensions, stroke, journal diameters, shaft lengths, taper, keyway, thread configuration, and engine applications are not identified in the supplied product information; verify these specifications before ordering
• Do not select a crankshaft based solely on general appearance or approximate dimensions
• Compare the original crankshaft’s overall length, journal diameters, shaft ends, tapers, keyways, threads, shoulders, bearing surfaces, and connecting-rod interface
• Inspect associated crankshaft bearings, connecting rod, piston, crankcase, seals, flywheel, keys, clutch or drive components, and mounting surfaces for wear or damage
• A damaged crankshaft may be associated with additional internal engine damage; inspect related components before reassembly
• Check crankshaft bearing and seal surfaces for proper condition and verify that mating components fit correctly
• Verify whether bearings, seals, keys, washers, nuts, connecting-rod components, or other engine hardware are included or must be purchased separately
• Use the applicable manufacturer procedures and specifications for assembly, lubrication, clearances, fastener torque, and crankshaft alignment
• Keep all internal engine components and mating surfaces clean and free of dirt, abrasive particles, and other contamination during installation
• After assembly, verify that the crankshaft rotates smoothly without binding or abnormal resistance before completing engine installation and returning the equipment to service
