Neil, that's the motor. It may (or may not) be the same electrical guts as
other Bosch blower motors with a different plastic housing and/or fan. I
don't know.
I have had them apart like shown in the samba link. Someone on our list had
an even better tutorial, it has worked great on several motors. After
refurbishing sewing machine motors for years, I can tell you that I have
had good success with sewing machine oil--nice and thin--and pack in and
around the bearings with Singer grease. It comes in a tube, and when it
gets hot from friction, it melts a little bit of itself again and again for
years. If you could find some sintered or oil filled bronze bearings to
fit, or sealed bearings, you would never have to do this again. But without
that, the grease and oil seem to be a reasonable solution.
Some people, even in the sewing machine community, use tri-flow, a bicycle
chain lubricant with teflon powder, basically. Since a bicycle chain gets
up to maybe 100 degrees, I am not certain that a lubricant designed for a
chain would work well in the tight clearances and higher temperatures of an
electric motor. So, I stick with sewing machine oil and singer grease. I
have never had to re-do one, but I hope to live long enough to have to.
If you are going to use the Mullendore Port of one if its variants, just
use spray lithium grease. Before the vehicle evaporates and leaves you with
thick white grease, it is thin enough to penetrate some ways. You may have
to keep doing it every few years, but once the hole is in place, that is a
small price to pay.
