Quoted from DavisAZ:Has anybody cleaned or fixed the motor for the spinning bumpers?
I actually have both the Replay and Add-a-Ball versions of Loop-the-Loop, but haven't gone
through either yet, but have experienced in many 50V motors.
Sometimes the motor's casing does need to be takin' apart, but many times just cleaning the
armature shaft makes a huge difference. Even sometimes just a couples drops of light weight
oil on the armatures shaft, but what I would first try is taking the fan off the motor, then pulling
the two screws behind where the fan was so the armature can be pulled out. Keep an eye out,
sometimes there's some small chims. No big deal, just have to put them back in place.
Then clean the stems of the shaft and apply a thin layer of oil on the stem. Put the armature back
in place, and before screwing back on the piece, clean the hole that the stem rides in and maybe
apply a drop of oil. Then the fan, and all set. Doing this can't hurt, but could make a big difference.
On the mushrooms, pulling the C clip should do the trick..
