Description

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 V1.1 is designed to fit the later model S-4020 and S-4025 series motors, built after November of 2010, or the new style SII-4020 and SII-4025 motors. This kit contains two bearings, one for the rear side and one for the front side of the motor. Both bearings it this kit measure 13mm OD x 6mm ID x 5mm thick. These bearings are exact replacements for the stock bearings that come with the motors. If you have a older model S-4020 or S-4025 motor that has 3 bearings in it, you need to purchase the Version 1.0 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.
