Good To Know
Q: Do I need to grease this spindle assembly before installation? A: The assembly arrives pre-greased with sealed bearings, so no initial greasing is required. Check for any grease fitting and follow your mower’s maintenance schedule for periodic lubrication.
Q: How do I ensure correct fit for my mower? A: Match your deck size and the original spindle part number to the cross-references listed. Verify the bolt pattern and shaft length, as production changes can affect fitment.
