[Yaaarc] Repairing LEGO motors 71427

[Steve Hassenplug]

I don't have a suggestion for repairing the motor, but I have found LEGO to 
be VERY good about replacing defective motors.  I've talked with their 
customer service on more than one occasion, and they've been pretty quick to 
replace them.

I was hoping to assemble a quick and dirty LEGO Sumo for the upcoming Sumo 
Contest.  As luck would have it one of my Lego motors (old gray 71427) is 
seized up.  I'm pretty sure that the motor worked fine when I put it away 5 
years ago.  It was easily able to remove the back cover but I can't seem to 
disassemble the motor any further.  I googled and could fine no active 
disassembly instructions.  I did fine one reference that said the permanent 
magnets are made of sintered magnetic power which seems to turn to dust in 
about 1/3 of the motors.  If anyone knows otherwise please let me know.

Thanks
Jim Ronald
