This is what the average 52 year-old Lucas wiper motor looks like, taken apart. Actually the main case [top, left] and the mount [center, top] have already been cleaned up, ready for paint. This sucker was STIFF and actually had to be carefully pressed apart. 52 years in a crusty old Saab will do that to you, I reckon....
The build date was "02-66", so I wasn't surprised to have to dig the old, dead grease out of the gears with dentist's torture tools. The armature [bottom center] was burned and I carefully turned it just a bit on my lathe. After that it was just a ton of clean-up, brush and spring replacement, greasing [with modern temperature-stable, non-hardening lubricants], and reassembly.
Above is the wiring diagram for this motor in a '68 Sonett V4. The schematic for the same motor in the same year Saab 95/96 is almost identical.
Here is the 52 year old motor, cleaned, reassembled, adjusted, tested, painted and ready to go to work for another 50+ years. Good stuff, Olaf!
