Yep, I have about 8-10 broken pairs now, cuz cuz I keep grabbing a pair and playing with them... eventualy after flipping them pulling them apart a few times waiting for files or in chat rooms etc.. they break

, usualy when I show them tos ome one else I wind up breaking them lol... I should problysell all the broken ones for something
If I were to install a pair into an X-Speed I would not need a soldering iron.. to do it

. unless I hapen to break a power or capacitor wire...
I usualy remove the end cap, by seperating it from the brush holder... then I bend the capacitors up, bending their wires, doing this too often to a capacitor WILL break it sometimes just once... then I remove the armature, swap the mags bend the brushes back down, make sure the brushes are siitting as good as possible... then I put the plastic end back on...
The trick/problems to X-Speeds is the metal bushigns on the shaft, if they are not inline once the motor is reassembled the armature will drag on them... eating at some of the torque, this is why I prefer bearing cans... but even then you need the bearings inline.. just does not have to be quantum accuracy.
