In order to keep your motor in top running condition, you need a good set of bearings. Occasionally, after a crash or landing in the dirt, the bearings can become damaged and need to be replaced. The Scorpion 40mm Motor Bearing Kit includes a set of three original equipment replacement bearings to fit all of the Scorpion 40mm S-Series motors.

The 40mm Bearing Kit is designed to fit the earlier model S-4020 and S-4025 series motors, built before November of 2010. This kit contains three bearings, one for the rear side and two for the front side of the motor. The rear bearing measures 13mm OD x 6mm ID x 5mm thick, and the front bearings measure 10mm OD x 6mm ID x 3mm thick. These bearings are exact replacements for the stock bearings that come with the motors. If you have a newer model S-4020 or S-4025 motor, or one of the updated SII-4020 or SII-4025 motors,you need to purchase the Version 1.1 S-40mm Bearing Kit.

Please note: The bearings are an exact fit into the motor housings, so they do fit snugly. When removing the old bearings, you may need to gently tap them out. However, when installing the new bearings, do not tap them in with anything, as this can dent the ball races and ruin the bearings. When installing ball bearings they need to be pressed in by the outer part of the race. Never apply pressure to the inner race, as this can damage the bearing and lead to premature failure.

If you have never changed the bearings in a motor before, we suggest that you watch the following video that shows the correct methods to change your bearings.
