How should I install and maintain the spindle assembly?

Installation replaces your worn or damaged spindle using the supplied hardware; basic hand tools and proper torque are all that’s needed. For long service life, add high-temperature grease through the grease nipple until fresh grease reaches the seal, and avoid excessive overfill to reduce cleanup.

• Compare mounting hole spacing and height to confirm fit before bolting
• Grease through the zerk fitting until grease appears at the sealing ring
• Do not overfill with grease — wipe excess to prevent debris build-up
• Torque bolts to your mower manufacturer’s specification during install

Which OEM pulleys and part numbers does the pulley replace?

The included pulley is specified to replace several OEM references from Ariens, AYP and Husqvarna, making this assembly a practical swap for many service scenarios. If your mower lists any of the referenced part numbers, this unit provides a direct-fit pulley option.

• Pulley replaces Ariens 21546446 and AYP 195945 / 197473
