Not the gear box
fault. You must remove all the old dried grease on tracks and
replace with a non hardening grease. Gear boxes should last another 50
years.

Terry McTaggart here. Over the last few years, I have experianced
two failures in the power window gearboxes in my 300F. Both failures
were identical, in that the plastic gear teeth surrounding the metal disk
inside the gearbox broke, rendering the gearbox useless. Fortunately I
had two spares in the attic and was able to replace the offending part.
Now, however, I have no more spares and the next failure (if there is
one) will be a major problem. Has anyone else experienced this
failure, and if so, might this be a good project for the repro
committee?
