I have not taken my locked motor apart (see below) but if it is a gear
that is stripped then, as a last resort, these can be replaced with a
custom made one. If you are lucky enough to know someone who is a
machinist, or in the local Model Engineering Society you can get them to
make a replacement from aluminum or brass pretty cheaply. If you need
to resort to a machine shop, depending on you luck, you might get it
made for a reasonable price. Although not for this type of Lego motor,
I have had small gears and parts custom made for as little as a 6 pack
of beer :-)

I also have a motor that is locked along with a second that is
intermittently making a grinding noise. I emailed Lego about getting
them replaced and explained the situation. Unfortunately their response
was to the tune of CAN$37.00 for each motor. Needless to say I did not
get replacements from them. In my case I was lucky and came across 3
kits for CAN$20.00 each that contained a motor.
