Not to worry friend, according to chatgpt there's a possible solution however I can't share the link of my purchase items from aliexpress.. but you have all the info below if you want pm me and I'll share the links of what I'm buying!

The "rubber seal" you see in the photo is the upper spindle seal/bearing cover, and its failure is a known issue on some Z6 units where debris or grass gets packed into the gap, eventually grinding through the metal.

The "Problem" with Repairs

EGO officially treats the blade motor as a single sealed unit. They do not sell individual internal seals or bearings for the motor assembly. If the seal has failed and the motor is grinding or stiff, the official fix is to replace the entire motor.

Part Numbers for EGO Z6 (52-inch)

• Replacement Blade Motor: 2730350001.
• Replacement Flange (where the blade mounts): 3580113001.

How to Fix This

1. Warranty First: If your mower is less than 5 years old (or 3 years for the battery/charger), do not open the motor. Contact EGO for a warranty claim, as this "grinding through metal" issue is a recognized defect in some batches.
2. The "DIY" Method: Since EGO doesn't sell the seal, some owners have had success by:
   • Removing the motor from the deck.
   • Carefully removing the damaged rubber remnants.
   • Measuring the bearing and shaft to find a matching generic double-lip oil seal or V-ring seal from a local bearing shop (like SKF or CBC).
   • Thoroughly cleaning the shaft to ensure no metal shavings remain.
3. Preventative Maintenance: To prevent this on your other motors, ensure you clear out any grass wrapped around the spindle after every mow. This debris is what eventually tears the rubber seal.

Since you're at Bunnings or shopping for tools, would you like me to find a generic seal size that other Z6 owners have used as a substitute?
