did you lubricate the motor after this treatment and, if so, what lubricator
you did use?
As you may have read in the 'Z Club 92' Club Revue 4/2000, my little F7 machines
run during a 4 day exhibition in Cologne on my layout without problems for more
than 35 hrs a distance of about 13 miles! Only then, one loco of the double
traction set refused to run further. I used as lubricator 'Ballistol'.
> New experience: I had a motor from a Marklin F7 which was unusable due to a
> "ring of fire" running around the commutator. No chemical, brush, or solvent
> I had would touch it. But thanks to another member, I got the opportunity to
> drop the motor into a 70% alcohol bath in an ultrasonic cleaner (MicroMart,

> the best motor I own. It ran for hours and hours non-stop at last week's two
> day GATS show here on the Z-Bend Track modules. Very impressed. I'm saving
