Important Notes

• Verify compatibility with your specific mower model, product number, serial number, transmission configuration, and production revision before ordering.
• Husqvarna parts sources identify 532428450 specifically as “KIT.O-RING/WASHER.”
• Sears PartsDirect describes 532428450 as a genuine OEM lawn and garden equipment engine O-ring kit and cross-lists it for Husqvarna and several related equipment brands.
• 532428450 supersedes previous OEM part numbers 532057143 and 532075143.
• PartsTree specifically documents 532057143 O-Ring Washer Kit as superseded to 532428450.
• Do not select replacement O-rings or washers based solely on appearance. Diameter, thickness, material, hardness, sealing characteristics, and equipment application can vary.
• Inspect the mating shaft, transmission, wheel-drive components, spacers, bearings or bushings, and surrounding hardware when replacing the kit.
• If the original O-ring is cracked, flattened, or deteriorated, inspect the mating surfaces for wear, corrosion, scoring, or other damage that could prevent proper sealing.
• Clean the applicable sealing and mounting surfaces before installation.
• Avoid damaging the replacement O-ring with sharp edges, threads, or tools during installation.
• Do not excessively stretch or twist the O-ring during assembly.
• Install the washer and O-ring in the same factory locations and orientation specified by the applicable equipment parts diagram.
• Some suppliers sell this part individually, while others advertise packs of five, so listing quantity should be confirmed with the actual inventory being sold.
• This listing should therefore state the exact quantity being supplied rather than assuming the manufacturer's or distributor's package quantity.
• This listing is for the Husqvarna 532428450 O-Ring & Washer Kit only unless otherwise specified. Transmissions, drive shafts, wheels, pulleys, bearings, bushings, and other mower components are sold separately.
• Match part number 532428450 with your equipment's illustrated parts diagram or OEM documentation before ordering to ensure proper fitment.
