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 HK-40mm Motor Bearing
Kit includes a pair of original equipment replacement bearings to fit the
Scorpion HK-4025 and HK-4035 Series motors.
These bearings measure 16mm
OD x 8mm ID x 5mm thick, and are an exact replacement for the stock bearings
that come with the motors.
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.
