Important Notes

• Verify part number 539101231 before ordering
• Confirm compatibility with your specific Husqvarna equipment model and idler assembly
• Compare the original spindle’s overall length, shaft diameter, threaded sections, shoulder dimensions, mounting configuration, attachment points, and overall profile
• Do not substitute an idler spindle based solely on approximate dimensions or appearance
• Inspect the associated idler pulley, bearing or bushing, idler arm, belt, tension spring, belt keeper, washers, spacers, retainers, and mounting hardware for wear or damage
• Excessive spindle wear can contribute to pulley wobble, misalignment, uneven belt wear, noise, or improper belt tracking
• Check the idler pulley for smooth rotation and excessive radial or axial play before reassembly
• Verify whether the idler pulley, bearings, bushings, washers, spacers, retainers, nuts, or other mounting hardware are included or must be purchased separately
• Do not apply lubricant to belt-contact surfaces; lubricate spindle or bearing components only when specified by the equipment manufacturer
• Shut off the equipment and ensure all moving components have stopped before servicing the belt or idler system
• After installation, verify proper spindle mounting, pulley alignment, free rotation, belt routing, tension, tracking, and clearance before returning the equipment to normal operation
