Important Compatibility Note

Some earlier-production Xnova 4025 motors were produced with a 2-bearing configuration, while later versions use 3 bearings. If you have an older 4025 motor, please verify the motor model and serial number before ordering.

For later-production 4025 motors, the 3-bearing configuration applies from the following serial numbers onward:

• 4025 / 1.5Y-1120KV 8P: SN V2-0090 and above
• 4025 / 2.5Y-670KV 8P: SN V2-0005 and above
• 4025 / 2Y-830KV 8P: SN V2-0004 and above
• 4025 / 3Y-560KV 8P: SN V2-0066 and above

Motors with serial numbers below those listed above may require the earlier 2-bearing replacement set.
