Important Notes

• Verify part number 539112124 before ordering
• Confirm compatibility with your specific Husqvarna mower model and mower deck configuration
• This component is identified for an applicable 52" mower deck application; the 52-inch designation refers to the deck/application and should not be interpreted as the physical diameter of the pulley
• The exact pulley diameter, overall width, groove width, belt profile, bore diameter, hub dimensions, offset, material, finish, bearing configuration, and mounting dimensions are not identified in the supplied product information
• The specific pulley position or function within the deck system—such as spindle, idler, tensioner, or other drive position—is not identified in the supplied product information; verify the applicable parts diagram before ordering
• Compare the original pulley’s diameter, groove profile, bore or mounting interface, hub configuration, offset, alignment, and installation position
• Do not substitute a pulley based solely on approximate diameter, appearance, or mower deck size
• Inspect associated mower deck belts, spindle assemblies, idler pulleys, tensioner arms, bearings, shafts, springs, belt guides, brackets, washers, retainers, and mounting hardware for wear or damage
• Check the pulley for worn or damaged grooves, cracks, bending, wobble, corrosion, rough rotation, excessive play, misalignment, or abnormal belt wear
• A worn, damaged, or misaligned pulley may contribute to belt slipping, belt derailment, abnormal noise, vibration, uneven belt wear, reduced blade drive, or premature belt failure
• Repeated belt failure may indicate another problem such as pulley misalignment, seized or worn bearings, incorrect belt routing, improper tension, damaged belt guides, or worn spindle components
• Verify the correct belt routing before removing components and follow the applicable mower deck routing diagram during reassembly
• Make sure the replacement pulley aligns correctly with adjoining pulleys and allows the belt to track properly without rubbing nearby components
• Keep pulley and belt surfaces free from oil, grease, fuel, and other contaminants that could affect belt performance
• This listing is for the 52" mower deck pulley; do not assume that belts, bearings, spindle assemblies, idlers, tensioners, springs, washers, retainers, mounting bolts, or additional deck components are included unless specifically stated
• Shut off the engine, remove the ignition key, disconnect the spark plug where appropriate, and allow the blades and all moving components to completely stop before servicing the mower deck
• After installation, verify proper pulley fitment, mounting security, alignment, belt routing, belt tracking, component clearance, free movement, and overall mower deck operation before returning the equipment to normal service
