 Wiper motors again! This ugly duckling is a Lucas motor for a late SAAB 95 or 96. This one was in its fairly ugly, not working, state when I received it.   Nasty....
 Here is the same motor...DE-nastified, and ready to be reassembled and tested.
 Ah, Henry Ford would be proud of me....three of 'em reconditioned and ready for reassembly.
...and here they are, ready to do their duty happily in a vintage SAAB 95 or 96.  All have been tested for both speeds, plus self park.  Neat, aye?


 SAAB speedometer reconditioning time again, but this time a SAAB 99 EMS speedo!
These units are full of plastic gears [typical of bean counter work at VDO, I assume] and in the top photo you can see the END of one [of 2] bad plastic gears in this speedo. It is the white gear between the two spiral gears.
This is the speedometer out of the 78 EMS. All looks good here.

 The top [main] register has a grey, toothed gear at the right end --it is mostly lead and is pressed onto the register shaft. After umpteen years of work, it loses its grip
--literally--and the odometer stops odometering.  I replace that gear--using a number of very special puller and pusher and holder tools--with a gear made of some modern, miracle plastic that is tough and won't slip on the shaft.
This photo shows the bad [cracked and slipping] small, white gear, the main register shaft, and just inside the speedometer frame, the bad [also slipping] part lead drive gear. I replaced both gears, lubed the unit, set the odometer to the  figure the customer wanted, then reassembled it and calibrated the speed. Every speedometer has a specific gear ratio. The master VDO book [which I have] shows speeds for the speed needle, given various input speeds [from the speedometer cable]. I use a calibrated input speed, and set the speed needle to agree with the VDO figure for that speedo's gear ratio.   No guess work.  We all like the speedometer to read right. This one is ready for another 87,000 miles.... 


 SAAB/Lucas wiper motor reconditioning time again--three of 'em at a time. Most of 'em look like the one shown above when I take 'em apart---YUK!  No wonder they don't  work worth a damn.  Well...over 40 years of working wiper blades....
 Here are three of them--reconditioned. One assembled [on the right], two ready to go together.  
 Ahh...that's better. The brush plate inside has been replaced on this one--you can see where the wires to the self-park switch and main connector have been spliced.
Here is one of the motors on my test bed. I can test any style Lucas motor with this unit. The electrical connections are exactly the same as if the motor was mounted in a car.  No guess work here---I run the motors for a while, on both speeds, and test the self-park feature.  Nothing like the right tools for the job--aye?
