SAAB WIPER MOTOR 3RD SERIES

The third series of Lucas wiper motors used by Saab for the 95V4 wagon and 96V4 sedan was an interesting combination of several Lucas units. I always make extensive rough drawings of ANY mechanical part I take apart, like the rough of this motor, shown below. That way, after the parts are all cleaned, reconditioned, painted, etc, and scattered all about, I know how it all goes back together again, with no guesswork.

While Lucas wiper motors are all similar, there are important differences. The drum wheel [lower left in the drawing] is different from one style motor to the next, as are mounts and self-park switches. Incidentally, the drawing is one of FIVE I made to further detail this Lucas motor.

This is the disassembled motor. You can see why the rough drawings are important. I have already cleaned the grunge off the outer "can" and the main mount [top, center]. I have also cleaned out 30 years or so of nasty, mostly hardened grease off the gear case and drum gear [center left]. The badly worn brush plate and wire assembly is at bottom right.

AH! NICE LIKE NEW DEPT: The armature [left] has been thoroughly cleaned and the commutator [the brass "thingie" at the center of the armature] lightly turned. The main gear case has the new brush plate assembly installed. Time for lubrication [with modern, temperature stable, non-hardening lubes] and final adjustment and assembly.

Here is the finished, assembled motor ready to go to the owner. I showed you my test bed for wiper motors in an earlier blog and this motor passed the bench test with flying colors. No reason this motor won't give years and years of reliable service.
