SAAB WIPER MOTOR PART TWO

This is what usually gives up in a Lucas wiper motor--the brush plate. I keep a good supply of these on hand because ALL these 40+ year old Lucas motors need a new brush plate to run like new once again.

After about a jillion rotations of the armature, the brushes wear down, the brush springs get weak [and sometimes rusty]. Result? Motor runs slow, or not at all. No big deal unless it rains...

At this point, I have turned the armature commutator, installed a new brush plate, lubed the moving parts and tested the self park switch. Lord Lucas' wonder is ready for the final assembly, adjustments and bench testing.

This delightful array of switches, wires, relays and holders is my bench tester for ALL the Lucas wiper motors. With it, I test the speeds, self park and general operation of the assembled motor. It's nice, y'know, to see that the sucker is actually working right when it's connected to an actual circuit, just like the one in the car.

This is what the reconditioned Lucas wiper motor looks like just before I chuck it into a CLEAN bag, box it and ship it to the customer. Pretty cool, eh?
