4. Maintenance
Regular maintenance of your Exmark equipment, including the spindle and seal, is vital for extending its lifespan and ensuring safe operation. While the 116-3341 is a sealed unit, general deck maintenance is important.
4.1. General Maintenance Tips
- Regular Inspection: Periodically inspect the spindle assembly for any signs of wear, damage, or excessive play. Check for unusual noises during operation.
- Clean Deck: Keep the underside of the mower deck clean to prevent buildup of grass and debris, which can put extra strain on the spindle bearings.

- While the 116-3341 is a sealed unit, any visible leakage around the spindle housing could indicate a seal failure or damage to the unit itself, requiring replacement.
For persistent issues or complex repairs, it is recommended to consult a certified Exmark service technician or refer to your equipment's detailed service manual.
